Dear Porsche-Owner

Before going on a trip...

A lot has gone into the manufacture of your

Porsche, including advanced engineering,

techniques, rigid quality control and de-

manding inspections. These engineering and safety features will be enhanced by

you...

the safe driver...

who knows his car and all controls, who maintains his vehicle properly, who uses his driving skills wisely, and always

drives within his own capabilities and his level of familiarity with his vehicle.

You will find helpful hints in this manual on how to perform most of the checks listed on the following pages. If in doubt, have these checks performed by your Porsche dealer.

First things first

• Turn the engine off before you attempt any checks or repairs of the vehicle.

• Be sure tires are inflated correctly. Check

tires for damage and tire wear.

• See that wheel bolts are properly tightened and not loose or missing.

• Check engine oil level, add if necessary. Make it a habit to have engine oil checked

with every fuel filling.

• Check coolant level to assure sufficient

engine cooling.

• Be sure you have a well charged battery.

• Check brake fluid level. If too low, have brake system checked.

• Replenish windshield washer fluid.

• Check if front hood is latched safely.

• Replace worn or cracked wiper blades.

• See that all windows are clear and unobstructed.

• Keep air intake slots and area between engine hood and windshield free of snow and ice, so that the heater and the

windshield wipers work properly.

• Check whether all light lenses are clean.

• Be sure all lights are working and headlights are aimed correctly.

• Check under vehicle for leaks.

• Be sure all luggage is stowed securely.

Emergency equipment

It is good practice to carry emergency equipment in your vehicle. Some of the things you

should have are: window scraper, snow

brush, container or bag of sand or salt, emergency light, small shovel, first-aid kit, etc.

Page 10

In the driver's seat...

On the road...

• Check operation of horn.

• Position seat for easy reach of controls.

• Adjust inside and outside rear view mirrors.

• Attach your safety belts.

• Check operation of foot and parking brakes.

• Check ail warning and indicator lights and

the information system display with ignition on and engine stationary.

• NEVER leave car idling unattended.

• Lock doors from inside, especially with children in the car.

• To prevent inadvertent opening of doors

from inside or outside, drive with locked

doors.

• Never drive after you have consumed alcohol.

• Always have your safety belt attached.

• Always drive defensively. Expect the unexpected.

• Use signals to indicate turns and lane changes.

• Turn on headlights at dusk.

• Always keep a save distance from the vehicle in front of you, depending on traffic, road and weather conditions.

• Reduce speed at night and during incle-

ment weather.

• Observe speed limits and obey road signs.

• When tired, get well off the road, stop and

take a rest. Turn the engine off. Do not sit

in the vehicle with engine idling. See

WARNINGS on "Engine Exhaust".

• When parked, always see the parking brake. Move the selector lever to "P" (Au-

tomatic transmission) or move the gear-

shift lever to reverse or first gear (Manual transmission). On hills also turn the wheels toward the curb.

• When emergency repairs become necessary, move the vehicle well off the road.

Turn on emergency flasher and use other warning devices to alert other motorists.

Do not park or operate the vehicle in areas where the hot exhaust system may come in contact with dry grass, brush,

fuel spill or other flammable material.

• Make it a habit to have the engine oil checked with every fuel filling.

Page 11

Break-in hints for the first

1.000 miles/1.600 kilometers

Engine exhaust

There are no specific break-in rules for your

Porsche. However, by taking a few precau-

tions you can help extend the service life and

performance of your engine. During the first 1.000 miles/1.600 km, all

working components of the engine adjust to

each other to a certain degree. Therefore:

Avoid full throttle starts and abrupt stops.

Change speeds frequently. Vary the throttle load.

Do not exceed maximum engine speed of

5.000 rpm (revolutions per minute). Do not run a cold engine at high rpm either

in Neutral or in gear.

Do not let the engine labor, especially when driving uphill. Shift to the next proper gear in

time (use the most favorable rpm range). There may be a slight stiffness in the steer-

ing, gearshifting or other controls during the break-in period which will gradually disappear.

Never lug the engine in high gear at low

speeds. This rule applies all the time, not

just during the break-in period.

Breaking-in brake pads

Brake pads do not have maximum braking efficiency when the car is new. Therefore, more pedal force is necessary during the first 100 to 150 miles/150 to 250 km. This also applies to replacement brake pads.

Breaking-in new tires

New tires do not have maximum traction.

They tend to be slippery. Break in new tires

by driving at moderate speeds during the

first 60 to 120 miles/100 to 200 km, and

longer braking distances must be anticipated.

Engine oil consumption

During the break-in period oil consumption may be slightly higher than normal.

As always rate of oil consumption depends

on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant.

WARNING

• Engine exhaust is dangerous if inhaled,

• Never start or let the engine run in a

closed garage. Never sit in your car for

prolonged periods with the engine on

and the car not moving.

• Although exhaust fumes from the en-

gine have many components which you can smell, they also contain carbon monoxide, which is a colorless and odorless gas. Carbon monoxide can be fatal if inhaled.

• If you smell gas fumes in the vehicle,

drive with the windows open but keep the hatchback closed. Have the cause immediately located and corrected.

• Because of inherent hazards, we do

not recommend transporting objects larger than those fitting safely into the luggage compartment. Keep the hatchback closed while driving to prevent poisonous exhaust gas from being drawn into the vehicle.

• Never carry additional fuel containers

in your vehicle. Such containers, full or partially empty, may leak, cause an explosion, or result in fire in case of a collision.

NEVER invite car theft!

WARNING

An unlocked car with the key in the

ignition switch invites car theft.

A steering wheel lock and a gong

alarm are standard equipment in

your Porsche. The gong will sound

if you open the driver's door while

the key is still in the ignition lock. It

is your reminder to pull the key out of the ignition lock and to lock the

doors.

WARNING Always remove the ignition key,

especially if children are left unattended in the vehicle. Unsupervised use of any vehicle key may

cause serious personal injury. NEVER leave your vehicle unat-

tended with the key in the ignition

lock. Take the key and lock the

doors.

a Key with built-in flashlight

b Flat key c Rear glove compartment key d Key for lockable wheel nuts

Keys

Three keys are supplied with the vehicle.

Each fits the ignition lock, door locks, hatch-

back lock, fuel filler cap lock and glove com-

partment lock. There is one flat key which you can keep in

your purse or wallet, for instance, as an "emergency key". If you remove the plastic

head of the flat key, you can clip on an illumi-

nated plastic handle (available from your

Porsche dealer). Vehicles with a rear seat glove compartment receive two additional

keys for the compartment lock.

NEVER remove the key from the steering lock while you are driving or as the car is rolling to a stop. The steering column will lock when you remove the key, and you

will not be able to steer the car. This may

result in a serious accident.

Because of the symmetrical shape of the key

shaft, there is no "wrong" way of inserting

the key in the locks. The new format of the keys makes unau-

thorized duplication of the keys virtually im-

possible. This means, however, that you

yourself will not be able to get replacement

keys cut, unless ordered from the manufac-

turer.

For the lockable wheel nuts, three identical

keys, are included. When taking the vehicle to your Porsche dealer or to a workshop for wheel or tire service, remember to leave one

key with the service attendant.

In case of loss, duplicate wheel look keys cannot be furnished by your Porsche dealer. Do not leave these keys in the vehicle. Keep

them in a safe place. See "Lockable wheel nuts" for details.

NOTE: It is a good idea to also keep a re-

cord of your key numbers in your wallet together with your license.

Page 14

Key number

The key number of the ignition key is impressed on a plastic tag which comes with the keys.

Detach this tag and keep it in a safe place.

For your protection against theft:

• Record the key numbers and keep them in a safe place, such as your wallet. Do not keep them in the vehicle.

• If you should lose a key, provide your Porsche dealer with the key number and

the vehicle identification number to obtain

a duplicate key.

Key light

Two of the keys have a built-in flashlight in the

key head. The beam from a small bulb in the key head illuminates the lower part of the key

stem. The flashlight is on as long as the contact but-

ton is depressed. The flashlight is powered by a 15 Volt button

battery. When the beam begins to fade, replace the battery, because an old battery

may leak and damage your clothes.

1. Use your finger nail or a small screw driver to carefully lift the key handle cover.

2. Insert a new, commercial available battery (1.5 V) in the contact button.

3. Assemble key top as shown in the figure.

Page 15

Anti-theft alarm

The alarm system is activated automatically when one of the doors is locked with

the key. Light-emitting diodes in the lock-

ing knobs flash to indicate that the alarm

system is activated.

If an attempt is made to force the driver's or passenger side door, engine compartment

hood or the hatchback or if the ignition is switched on while the alarm is activated a specially protected siren will sound for about 90 seconds. The engine cannot be started. Additionally the fog lights and stop lights will flash intermittent for the same time period.

The alarm system is switched off automati-

cally when a door is opened with the key. The light-emitting diodes go out.

If the hatchback is opened with the alarm

system activated, this alarm status is auto-

matically interrupted until the hatchback is reclosed.

Keep plastic tag with key number in a safe place. Do not leave it in the vehicle.

Central door locking system

The central door locking system enables you to lock or unlock both doors simultaneously. The doors are locked when the key is turned

in either door lock, or when the key is turned

further anticlockwise in the lock of the hatch-

back. Unlocking the hatchback will not unlock the doors.

The central door locking system functions

only when both doors are fully closed. If one door is "centrally" locked before the other door is fully closed, the "centrally" locked door will unlock automatically.

Page 16

The car is safely locked when locking knob "A" is fully down on both doors. If locking knob "A" is not fully down on one door, open that door again, close it firmly and repeat the

locking operation.

On a centrally locked vehicle, the passenger door can also be unlocked and locked from inside by turning locking knob "B". Locking knob "B" is operational only with door fully closed.

Central locking button With the ignition key in Pos. " 1" or "2" both

doors can be locked or unlocked by pres-

sing the central locking button in the center console. The button is illuminated when the doors are locked.

With the ignition key in Pos. "0" the central

locking system is operational by turning

knob "B".

Doors

To open doors from outside, pull the reces-

sed door handle.

To open doors from inside, pull recessed

handle "C" above armrest.

The armrests have a built-in storage com-

partment. To open, press knob in hand cutout and tilt armrest outward. To close, tilt compartment toward door panel.

The courtesy light in the lower door panel

"D" will come on when a door or the hatch-

back is opened. The light can also be turned on or off with the switch on the light housing.

Power windows

WARNING

Door warning lights

The red spot lights in the rear doorjambs will come on when a door or the hatchback is opened.

To open or close, depress the rocker

switches in the center console in front of the

shift lever. The power windows are operational when

the ignition is turned on. When the ignition is turned off or the ignition

key removed, the power windows can be op-

erated until one door is opened.

Do not put anything on or near the windows that may interfere with the driver's vision.

Remove the ignition key to shut off power to the window switches when the vehicle is not attended by a responsible person.

Remember, power is still supplied to the

window switches until one door is

opened.

Page 19

Front seat adjustments

The correct seating position is all-important for safe and fatigue-free driving. In order to satisfy individual requirements, the seat has

infinitely variable adjustment.

We recommend the following procedure for finding the correct position for the driver's seat:

1. Operate longitudinal adjustment until your leg is fully stretched with the clutch

pedal depressed while your foot is bent.

2. Adjust desired fore/aft height.

3. Clasp upper portion of steering wheel. Then adjust backrest inclination so that

both shoulders remain in contact with the backrest even with your arms fully stretched.

4. If necessary, correct the longitudinal adjustment.

Steering wheel adjustment

For maximum legroom and unobstructed view of the instruments, the height of the steering wheel, together with the instrument cluster unit, can be adjusted.

Release locking lever under instrument cluster for desired positioning (arrow), then lock securely.

Page 20

Lumbar support (B)

The lumbar support, which supports the spine, can be adjusted continuously with switch (B).

Lumbar support extend/retract

Lumbar support raise/lower

Seat heating system (A)

The heating system in the seat cushion and

backrest is switched on and off by pressing

the rocker switch.

Press upper half of switch - heating on Press lower half of switch - heating off

Front seats

Two multi-function switches control the electric motors for longitudinal adjustment, seat height and angle of backrest tilt.

Heating temperature is controlled with the aid of the knurled knob set in the switch; the temperature is held constant until the seat heating or the ignition is switched off.

Turn knurled knob up to increase temperature Turn knurled knob down to reduce temperature

Manual operation

Should the electrical seat adjustment fail, you can use the hexagon socket-screw in

the tool-kit for longitudinal seat adjustment

by turning the servo-motor below the front

of the seat.

Page 21

Seat position memory

The seat position memory can store up to three different sitting positions. Each position stored in the memory comprises longitudinal adjustment, seat height, backrest angle, position and size of lurnbar support and the position of the outside mirrors. The

positions can be adjusted, stored or called up regardless of whether the engine is on or

off.

Selecting a position

Adjust the seat and the two outside mirrors

to the desired position by operating the switches for seat and mirror adjustment,

Storing a position

To store a position in the memory, press the

memory button (arrowed) and the appropri-

ate position button (button 1, 2 or 3). The

memory button must be pressed before the position button.

Calling up a position

To set the seat to the position stored in the

memory, the appropriate position button

must be depressed until the seat reaches its final position. The procedure is curtailed as soon as the button is released. The buttons are illuminated for ease location.

Once the seat reaches its end position the

mirrors are set automatically to the positions stored in the memory.

The seat switches always take priority over

automatic adjustment. If a seat switch is operated, automatic adjustment is immediately interrupted.

.Pilotlamp

A red pilot lamp is set in the memory button

If adjustment is initiated, the pilot lamp lights up until the adjustment is completed. If the procedure is interrupted, the lamp goes out approx. 60 seconds after the ignition is switched off.

Page 22

In order to adjust the backrest, pull the in-

side locking lever at the front of the seat upwards, set seat to desired position and release the lever.

When there is no load on the backrest, it will

always be pushed forwards by spring force

when the lever is pulled.

WARNING

Front seat passengers should not ride in

a moving vehicle with the backrest reclined. Safety belts only offer protection when the backrest is upright and the belts are properly positioned on the body. Improperly positioned safety belts can cause

serious personal injury in an accident.

Sports seat

Longitudinal adjustment and backrest seats ad-

justment are carried out manually on sports seats

To move the seat backwards and forwards,

Pull the outside locking lever at the front of the seat upwards, move seat into desired position, release lever and ensure that the seat engages securely.

Never unlock the driver's seat while the

vehicle is in motion: the seat may move suddenly, causing you to loose control

over the vehicle.

Backrest release

The backrest can be folded forward for easy access to the rear seats. To release, pull the lever on the side of the backrest up (arrow)

and, at the same time, tilt the backrest forward. When the backrest is tilted back, the lock will engage automatically.

WARNING

For driver and passenger protection, backrest locks must be engaged at all

times while the vehicle is in motion.

Rear seats

The backrests of the rear seats can be tilted

forward to provide additional luggage space.

To release backrest, pull the lever on side of the backrest up and, at the same time, tilt

the backrest forward. To prevent luggage and other objects from

sliding around while the car is in motion, you can secure them with the luggage net. The

eyelets for this purpose can be found behind the rear bolster and on the luggage compartment floor.

Page 23

Heated outside mirrors with remote control;

When the rear window defogger/defroster is

switched on, the outside mirrors are also

heated electrically. The outside mirrors are adjustable from inside of the vehicle by a four direction switch and a rocker switch located on the left door next to the side window

vents in the armrest. The rocker switch

selects either the left or right mirror for ad-

justment. Press the rocker switch into the ap-

propriate position. Then the four direction switch will adjust the selected mirror in any of the four directions.

The mirror housing is hinged and can be

folded flat against the car in either direction to prevent damage in tight parking spots.

If necessary, the outside mirrors can also be

adjusted manually.

Rear view mirrors

Adjust the outside and inside mirrors before driving. It is important for safe driving

that you have good vision to the rear.

Inside day-night mirror

You can adjust the day-night mirror from clear daylight visibility to non-glare visibility

at night, by moving the lever at the bottom of the mirror forward or rearward.

Do not put decals or other signs on the windows that may interfere with the driver's vision.

Page 24

Safety belts

Warning

Failure to follow safety belt instructions may result in serious personal injury.

Instructions

• For your and your passengers' protection, use safety belts at all times while the vehicle is in motion. Use child safety seats for all small children.

• Safety belts must be properly positioned on the body. Improperly positioned safety belts can cause serious personal injury in case of an accident.

• Porsche recommends that all infants and children be restrained in child restraint systems at all times while the vehicle is in

motion in accordance with applicable

laws.

• The use of infant or child restraints is required by law in all 50 states and the Canadian provinces. The child restraint system should be one that complies with

U. S. Federal Motor Vehicle Safety Standard 213 and should be secured by a lap belt or the lap belt portion of a lap-shoulder belt. A statement by the seat manufacturer of compliance with this standard can be found on the instruction label

on the restraint and in the instruction manual provided with the restraint.

• When using an infant or child restraint system be sure to follow all manufac-

turer's instructions on installation and

use.

• Infants and small children should never be held on the lap, nor should they share a seat belt with another occupant while

the vehicle is in motion.

• Children too big for child restraint sys-

tems should use regular seat belts. A shoulder belt can be used providing it

does not cross the face or the neck of the

child.

• For maximum safety and protection, we recommend that small children travel in

the rear seats.

• For maximum effectiveness, the lap belt

should be worn low across the pelvic

crest.

• Belts should not be worn twisted.

• Do not wear belts over rigid or breakable objects in or on your clothing, such as eye glasses, pens, keys, etc. as these may cause injury.

• Several layers of heavy clothing may inter-

fere with proper positioning of belts.

• Belts must not rub against sharp objects.

• Keep belt buckles free of any obstruction that may prevent secure locking.

• Make sure that belt of the unoccupied

passenger seat is fully wound up on its retractor so that the belt tongue is in its

stowed position.

• Belts that have been subjected to exessive stretch forces in an accident must be

replaced.

• If belts show damage to webbing, bind-

ings, buckles or retractors, they should be replaced.

• If belts do not work properly, see your au-

thorized Porsche dealer.

• Do not modify or disassemble the safety

belts in your vehicle.

• The belts must be kept clean as otherwise the retractors may not work properly (see

also "Car care instructions").

• Never bleach or dye safety belts.

• Do not allow safety belts to retract until they are completely dry.

Safety belt warning system

An audio-visuel warning system is inter-

connected with the driver's safety belt.

Every time the ignition is turned on, the seat belt warning light in the instrument cluster

will come on for about 6 seconds as a remin-

der to buckle up. If the driver does not fasten

the safety belt, the gong will continue for the

duration of this 6 second period. The gong

will go off as soon as the driver has buckled

up.

Inertia reel retractor

The combination lap/shoulder belt with iner-

tia reel locking mechanism adjusts automati-

cally to your size and movements as long as

the pull on the belt is slow.

Rapid deceleration during hard braking or a collision locks the belt. The belt will also lock when you drive up or down a steep hill or in a sharp curve otherwise the shoulder belt will not inhibit your upper body movement.

• To fasten, grasp belt and pull belt in continuous slow motion across your chest and lap.

• Insert belt tongue into buckle on inboard side of seat. Push down until it securely

locks with an audible click. Pull belt to

check.

• Pull shoulder section to make sure belt fits snugly across the hips.

• Belts should fit snugly across the pelvis and chest. Make sure any slack is wound on the retractor.

Page 26

• To unfasten belt, push in release button on buckle. Belt tongue will spring out of buckle.

• To release a locked belt, lean back to take

the body pressure off the belt.

• To store lap/shoulder belt, allow belt to

wind up on retractor as you guide latch to

its stowed position.

Child restrained anchorages (Canada Models)

If your child restraint seat or seats require the

use of a tether strap you will want to use the anchor points provided on the panel behind the rear seats.

The right child restraint anchorage is shown

in the illustration (see arrow).

The hardware needed to attach the tether

strap comes with your Porsche. The

hardware can be moved to the other anchor point if required.

If a child restraint system is to be used, the necessary upper anchorage fitting must first be mounted on the respective anchor point.

Additional hexagon head bolts, spacers and

fittings are available from your Porsche dealer.

To ensure proper installation the anchor fittings or fitting assemblies should be instal-

led or repositioned by your Porsche dealer.

Warning

Child restraint anchorages are designed to

withstand only those loads imposed by

correctly fitted child restraints. Under no circumstances are they to be used for adult seat belts or harnesses.

Brakes

Functioning of brake system

Your Porsche is equipped with a power assisted hydraulic dual circuit brake system with disc brakes at the front and at the rear.

Both circuits function independently.

In the unlikely event of hydraulic failure of one circuit, push the brake pedal down firmly and hold it in that position. A mechanical linkage activates the second circuit, and you will be able to bring the vehicle to a stop.

Parking brake lever (arrows)

Parking brake force is mechanically transfer-

red to the rear wheels by means of cables.

Use the parking brake only after the vehicle has come to a full stop.

To set the parking brake

Press in the release button (arrow) at the end

of the lever as you pull the lever up. The park-

ing brake engages as soon as you release

the button in the raised lever.

To release the parking brake

Pull the lever slightly up as you depress the release button. Keep the button depressed

as you lower the lever.

WARNING

• Release the parking brake fully. A partially engaged brake will overheat the

rear brakes, reduce their effectiveness

and cause excessive wear.

• Always set the parking brake when

parking your car. Move the selector

lever to "P" (Automatic transmission) or move the gearshift lever to reverse or first gear (Manual transmission). On

hills also turn the wheels toward the curb.

The parking brake light and the fault message in the information system display will

go out after the engine is started and the parking brake is fully released.

WARNING

Failure of one brake circuit will impair the braking capability resulting in an in-

creased stopping distance.

If one brake circuit has failed, the other will still operate, However, you will notice an increased pedal travel when you step on the

brake. Should you encounter such experience, bring your vehicle safely to a full stop.

Avoid driving the vehicle and instead have

it towed to the nearest authorized Porsche dealer.

Page 28

Brake pedal

Brake operation and brake warning light

WARNING

• The movement of the brake pedal must never be obstructed by a floor mat or

any other object. In case one of the two

brake circuits fails, increased pedal

travel is required to bring your vehicle to a full stop.

• Make sure that the size of your floor mat does not hamper the movements of either brake, clutch or accelerator pedals in any way.

• Secure the floor mat against sliding into positions that could interfere with

the safe operation of your vehicle.

• Do not "ride the brakes" by resting

your foot on the pedal when not intend-

ing to brake. Overheating and prema-

ture wear of the brakes will result.

• Before descending a steep grade, re-

duce speed and shift transmission into a lower gear or driving position to control speed. Do not ride the brakes or

hold pedal down too long or too often.

This could cause the brakes to get hot and not function properly.

Make it a habit to check the operation of your brakes before driving.

The brake fluid warning light in the instru-

ment cluster comes on accompanied by the

fault message in the information system dis-

play to indicate that the level in the brake

fluid reservoir is too low. With correctly adjusted brakes, and a cor-

rectly working brake system, the pedal travel

to the point of brake actuation should be

1 -3/16" to 1 -9/16" or 30 to 40 mm. Whenever

the brake pedal travel exceeds this distance,

have the brake system checked. Keep in mind that the braking distance in-

creases very rapidly as the speed increases. At 60 mph or 100 km/h, for example, it is not twice but four times longer than at 30 mph

or 50 km/h. Tire traction is also less effective when the roads are wet or slippery. Therefore, always maintain a safe distance from the car in front of you.

Brake booster The brake booster assists braking only

when the engine is running.

When the car is moving while the engine is

not running, or if the brake booster is defective, more pressure on the brake pedal is re-

quired to bring the car to a halt.

Moisture or road salt on brakes affects

braking.

Driving through water may reduce the traction. Moisture on brakes from road water, car wash, or coating of road salt

may affect braking efficiency. Cautiously apply brakes to test them after being ex-

posed to such conditions. When the vehicle is driven on salted roads for extended

periods, the brakes should be hosed down thoroughly about every 2 weeks. An automatic car-wash facility cannot do this job properly. Brakes will dry after a few cautious brake applications.

Brake wear

Our automobiles have excellent brakes, but

they are still subject to wear, depending on

how the brakes are used. Have the brake system inspected at the intervals recom-

mended in your Warranty & Maintenance

booklet.

New brake pads or linings

Brake pads or linings may not have the highest possible braking efficiency when new.

Therefore, allow for longer braking distance

during the initial 100 to 150 miles or 150 to 250 kilometers of normal city driving if fewer stops are realized.

Page 29

ABS brake system

(Antilock brake system)

The ABS system represents a major contribution to the enhancement of active safety

in your vehicle. This system prevents the

wheels from locking in a panic stop on al-

most all road surfaces.

With ABS system in your vehicle, the fol-

lowing areas are enhanced:

Full steerability, vehicle remains steera-

ble under all braking forces.

Good directional control, no swerving caused by locking of wheels under braking conditions.

Excellent stopping distance, stopping distances are usually reduced because controlled braking is maximized.

Prevention of wheel lock up, no brakeinduced sliding and thus no localized tire

wear from emergency braking.

The crucial advantage of ABS system over a

conventional brake system is in the area of

maintaining directional control and man-

euverability of the car in emergency situa-

tions, including panic braking in turns.

WARNING:

In spite of the improved handling afforded

by the ABS system, it still remains the re-

sponsibility of the driver to adapt the driv-

ing style to the prevailing road and wea-

ther conditions, as well as, obeying traffic

laws. In no case, should the higher degree

of safety offered by ABS be regarded as a

justification for taking greater risks.

Other vehicles not equipped with the ABS system may not be able to maintain control, especially on wet or poor road surfaces and thus may be more likely to im-

pact you in the rear. To minimize that risk,

use your ABS system to increase your ability to maneuver to avoid dangerous situations and not merely to try to stop in the shortest distance possible.

Driving with the ABS system

A wheel speed sensor is fitted to each of the

four wheels. If wheel slippage of either of the front wheels or the rear wheels is sensed dur-

ing braking, the brake pressure is adjusted

automatically until the wheel no longer slips. The brake pressure is regulated for each front wheel individually and for both rear wheels together.

On a road surface which is slippery on only one side, the rear wheel which is braking on

the slippery surface determines the brake

pressure which will be applied equally to both rear wheels. This ensures that direc-

tional stability is maintained. However, if

braking force approaches the wheel lockingup point for all wheels (panic braking) the

ABS system will intervene in a way compara-

ble with rapid rythmic braking. The proper operation of ABS is perceived by the driver as a pulsating brake pedal in conjunction

with audible noise and perhaps some vibration. The driver is thereby warned to reduce vehicle speed appropriate for the prevailing

road conditions.

If your ABS system should ever malfunction,

the ABS system is automatically switched

off, but the normal brake system, without

ABS, would remain fully operational. Such a

malfunction would be indicated by the illumi-

nation of the "ANTILOCK" light accom-

panied by the fault message in the informa-

tion system display.

If the ABS system becomes inoperative,

take your vehicle to your authorized dealer immediately.

Page 30

Clutch

Due to the hydraulic operation of the clutch, a free travel of the clutch pedal of 0.1 " or 2.5 mm is necessary.

Should this free travel suddenly become bigger, it could mean a malfunction of the clutch. See your Porsche dealer for rectifica-

tion. Always depress the clutch pedal fully when

changing gears. Do not hold the car on a steep hill with the clutch pedal partially de-

pressed. This will cause premature wear or

damage.

Page 31

There are 4 switch positions:

0 Steering locked. All electric circuits

wired through the ignition switch are turned off. The ignition key can only be

. withdrawn in the "0" position. The parking

lights can be operated in this position by pushing the turn signal indicator lever up

and down (also see "Parking lights"),

1 Steering unlocked. In this position all

electric circuits are operational except for the following: turn signals, back-up lights, outside mirror remote control and rear window defogger/defroster.

2 Ignition on, steering unlocked. All elec-

tric circuits are operational. With the engine stationary, all warning lights will light

up for a bulb check. (Lack of engine oil can, in contrast to all other functions, only be checked with the engine turned off and with the vehicle on level ground.)

3 The starter is operated by turning the ig-

nition key to the right. As soon as the engine starts, release the key. It will spring back to position "2". With the engine running, the warning lights should go out except the warning light for the stop lamp, which will go out after depressing the brake pedal and the park brake light after

fully releasing the parking brake.

To conserve battery power, the electric

circuits for headlights, rear window defogger/defroster and wiper/washer system are temporarily interrupted during the starting process.

The starter should not be operated for more than 10 to 15 seconds at a time. If the engine does not start the first time or stalls at any time, the ignition key must be returned to the "0" position. The non-repeat lock in the switch prevents the starter from being operated when the engine is running and thus

from being damaged.

To remove the key and to lock the steer-

ing, turn the key back to position "0" and pull

it out. Turn the steering wheel until it locks.

WARNING Never remove key from ignition lock or

turn key off while vehicle is moving. The steering wheel will lock, causing loss of control.

Gong

If you leave the key in the ignition/steering lock, the gong will sound when the driver's door is opened. This is a reminder to remove

the key.

Starting procedures

WARNING

• Fasten safety belts before driving.

• Never start or let the engine run in an enclosed, unventilated area. Exhaust

fumes from the engine contain carbon

monoxide, which is a colorless and odorless gas. Carbon monoxide can be fatal if inhaled.

• Never leave engine idling unattended.

An unattended vehicle with a running engine is potentially hazardous.

• Do not park or operate the vehicle in

areas where the hot exhaust system

may come in contact with dry grass, brush, fuel spill or other flammable ma-

terial.

• Never leave engine idling. When starting engine, be ready to drive immediately. Maintain moderate speed until engine is warm.

Manual transmission: Move gearshift lever to Neutral.

Automatic transmission:

Move selector lever to Park.

Temperature sensors on the engine automatically provide the correct fuel/air mixture re-

quired for starting.

Therefore, it is not necessary to depress the

accelerator pedal while starting a cold or a

warm engine. When starting at very low outside tempera-

tures, fully depress the clutch pedal, so that the starter only has to crank the engine.

As soon as the engine starts, release the ig-

nition key.

If the engine fails to start after 10 to 15 seconds of cranking, wait about 10 seconds

before engaging starter again.

Do not let the engine idle to warm it up. After starting, drive vehicle at moderate speeds and with gradual accelerations. Avoid high rpm and full throttle operation until the engine has reached normal operating tempera-

ture.

Stopping engine Turn key back to position 0.

Do not stop engine immediately after hard or extended driving. Keep engine running at increased idle for about two minutes to prevent excessive heat build-up before turning off engine.

WARNING

• Before you check anything in the engine compartment, let the engine cool down. Hot components can burn skin on contact.

• The radiator fan switches on automatically when the coolant reaches a certain temperature and continues to run (even with ignition off) until the coolant temperature drops. Therefore, never touch the fan blades as they will rotate spontaneously when the thermoswitch turns the fan on.

If you have an automatic garage door...

The transistorized ignition system in your

Porsche may interfere with your electronically operated garage door. To check this: drive your Porsche close to the garage door and run the engine at different speeds.

If the garage door opens or closes without

your operating the garage door unit in your

car, contact the dealer who installed the au-

tomatic garage door to have the frequency

and/or coding of the garage door signal modified.

Page 34

Tachometer

Indicator system for position of gearshift

Speedometer

The transistorized tachometer operates on

the pulse count principle and shows engine

speed in revolutions per minute (rpm).

The red mark at the end of the scale indi-

cates the maximum permissible engine rpm.

Before reaching this area, the next higher gear should be selected. Earlier shifting saves fuel.

Shift to the next lower gear when the engine rpm drops below 1500 rpm.

Automatic transmission

Whenever the ignition is switched on, or the vehicle lights are switched on, the position of the gearshift lever lights up in the display field of the instrument cluster.

The display goes off when the key is re-

moved or when the vehicle lights are

switched off.

The speedometer indicates driving speed

per hour.

In USA: miles per hour In Canada: kilometers per hour

The odometer reading and the readings for tripmeters I and II appear in the information system display.

Page 35

Oil pressure gauge Oil pressure warning light

Fuel level gauge and

warning light

Engine oil pressure is shown in bar. At 5000 rpm with the engine at normal operating temperature the oil pressure should be about 5 bar. A slight drop in oil pressure at higher

temperatures is normal.

Should the oil pressure suddenly drop while driving or if the fault message appears in the informations system display, pull off the

road and stop the engine immediately.

Check the engine oil level. If oil level is correct, do not drive the vehicle as severe engine damage may result. Contact your nearest Porsche dealer for assistance.

Oil pressure warning light

The oil pressure warning light comes on when the ignition is turned on and goes out

as soon as the correct operating pressure is reached. Should the light come on during driving, this indicates that the oil pressure is not correct.

With the ignition on, the amount of fuel in the tank is indicated by the fuel gauge needle.

If the level is too low the fuel level warning light comes on and fault message appears in the information system display.

Fuel level warning light

This light comes on when the fuel reserve

level in the tank is down to about 2 U.S. gals, or 8 liters. Time to refuel.

Page 36

there is a malfunction in the electrical sys-

tem. If this is the case, contact your Porsche

dealer. If the light flickers or stays on while

you are driving, the V-belt may be loose or

broken. The belt should be retensioned or replaced. The fault may also be in the regulator

or the alternator itself. In this case, keep electrical consumption at a minimum and drive to the nearest workshop.

Needle in right field - warning If needle enters the right field, the engine is

overheating. The warning light comes on and fault message appears in the informationsystem display. Reduce speed and engine

rpm. If the needle does not return to the center field, and the central warning light re-

mains on, pull off the road, turn off the engine and let it cool down.

Coolant temperature warning light

Voltmeter Alternator warning light

The voltmeter shows the overall condition of the charging system. The needle should nor-

mally stay in the 12 -14 volt range when the

engine is running. A temporary drop below

12 volts when starting the engine is normal.

A fault message appears in the information-

system display if voltage is too low.

The alternator warning light comes on when the ignition is turned on and goes out as the

engine rpm increases. If the light does not light up when turning the ignition on, or if it does not go out after starting the engine,

Coolant temperature gauge and warning light

Needle in left field - engine is cold

As long as needle is in left field, avoid high

speeds and high engine rpm, until engine

has reached normal operating tempera-

ture. Do not lug the engine.

Needle in center field - normal

Under normal driving conditions, needle

should remain in center field. The needle

may reach the right field, especially at high engine loads, but should return to "normal" when engine load is reduced.

If the warning light comes on, check that the fans are working. See section "Cooling air flaps and fan control". If the fans are not

rotating, the power supply to the fan control

is defective. The cooling air flaps must be open. If necessary, open the flaps by hand as described.

If the problem cannot be readily located, be

sure the engine has cooled down sufficiently.

Then drive to the nearest Porsche dealer, but

carefully watch the coolant temperature gauge and the warning light. Try to avoid engine idling, very low speeds and engine

speeds in excess of 4000 rpm.

For other details refer to "Cooling System".

Page 37

Warning lights

The warning light comes on and stays on

until parking brake is fully released.

Every time the ignition is turned on, the seat belts warning light in the instrument cluster

will come on for about 6 seconds as a remin-

der to buckle up. The light will go out as soon as the driver has buckled up.

The warning light goes on in the event of a

malfunction in the ABS system. The system is switched off; the normal brake system remains fully operational. If the light comes

on, take your vehicle to your authorized dealer for service immediately.

The turn signal indicator light for trailer op-

eration is not connected.

The turn signal indicator light in the instrument cluster will flash with the switch lever in either up or down position. If a turn signal

bulb becomes defective, the indicator light flashes at about twice the normally frequency.

The high beam light in the instrument cluster

will light up when the switch lever is pushed

forward. The blue light will go out when

switching to low beam.

The indicator comes on when the parking

lights are turned on. The light will go out as soon as the headlights are switched on.

The warning light comes on and goes out after depressing the brake pedal. If the light stays on a bulb is defective.

The warning light flashes when the brake fluid l e v e l falls below the required minimum.

Page 38

Information system

The information system helps enhance road safety and operational reliability. Automatically and without any action on the part of the driver, it provides notification of faults in

a number of systems. In the event of a system malfunction, a symbol appears in the instrument cluster display, accompanied by an explanatory worded message.

The messages have been subdivided into three priority groups:

Priority I

Faults which are detrimental to road safety

and operational reliability are indicated by

red lettering and flashing symbols. Stop and

rectify the fault immediately.

Priority II

Faults which could cause damage to your

Porsche are indicated by red lettering and a symbol which does not flash. The fault in question must be rectified at the earliest possible opportunity.

Priority III

If a part has to be changed or the water in the washing-water reservoir topped up, the fault is indicated by red lettering and a sym-

bol which does not flash. In this event, it is not necessary to interrupt the journey immediately or seek the assistance of an au-

thorized Porsche dealer.

If the oil level is too low, the corresponding

fault message will appear as soon as the ig-

nition is switched on, irrespective of whether

the engine is started or not. The other fault

messages can appear once the engine has been started and the brake pedal pressed. If

the park brake is not released the warning

lamp remains lit, accompanied by the fault message at speeds above 10 km/h (6 mph).

Acknowledgement

Pulling the control lever acknowledges the fault message and cancels the worded message. The messages issued for priority I and

II faults are repeated 15 minutes after acknowledgement and 30 minutes after every engine start until the fault in question is rectified. Messages for priority III faults are issued once only. If the fault in question is not rectified, the message reappears every

time the engine is restarted only.

Faults of different priorities occurring simul-

taneously are displayed in sequence. Once

one fault is acknowledged, other faults of the same priority can be displayed, followed by those of lower priority. Each fault message

must be acknowledged in turn, before the on-board-computer and auxiliary functions can be called up.

tomatic speed control. The spring loaded

control lever operating the automatic speed control is located just below the wiper/

washer lever.

While driving with the automatic speed control set (at speeds above 30 mph or 50

km/h), do not bring shift lever into the Neutral position as excessive engine rpm

will result.

To operate the automatic speed control

Accelerate to the desired cruising speed,

push lever toward instrument cluster (arrow

1) and release. This sets the cruising speed

and stores it in a memory. After a second or two, automatic speed control will take over, and you can remove your foot from the accelerator pedal. The set cruising speed will be maintained automatically.

WARNING

Do not use the cruise control when it may be unsafe to keep the car at a constant

speed. For example, a constant speed

may not be safe in heavy traffic, or on

winding or slippery roads. With the cruise control system engaged, the engine speed will not return to idle when remov-

ing the foot from the accelerator pedal. Please observe all local and national

speed limits,

f Passing: When you want to drive faster for

a brief moment, for example when passing

another vehicle, actuate the accelerator.

When you take your foot off the accelerator

pedal, the preset speed will automatically be

resumed. Gearshifting: When shifting gears, the au-

tomatic speed control is only disengaged as

long as the clutch pedal is depressed. The preset speed will be resumed as soon as you

take your foot off the clutch pedal.

Braking and stopping: Whenever you apply the brake or come to a stop, the automatic speed control is disengaged. Move the lever down (arrow 2), and the preset speed will be resumed.

Switching system off: To switch the automatic speed control off, move the lever toward you (arrow 3). To resume the preset

speed, move the lever down (arrow 2).

To change the preset cruising speed

Increase preset speed:

Accelerate by depressing the accelerator

pedal. When the desired speed is reached push lever toward instrument cluster (arrow

1) and take your foot off the accelerator

pedal. Now the new cruising speed is set

and stored in the memory.

As an alternative, you can hold the lever in

the front position (arrow 1), without depressing the accelerator pedal. The car will accelerate on its own. When the desired speed is

reached, release the lever.

Decrease preset speed:

Apply the brake, which will disengage the au-

tomatic speed control. When the vehicle has slowed down to the desired speed, push lever toward instrument cluster (arrow 1) to set the new cruising speed.

As an alternative, disengage the automatic

speed control by moving the lever toward you (arrow 3). When the vehicle has slowed

down to the desired speed, push lever toward instrument cluster (arrow 1) to register the new cruising speed in the memory.

Note: When driving up a hill, if the engine

power is insufficient in a particular gear, the speed control will be disengaged automatically. Shift to a lower gear to avoid lugging the engine.

The air outlets for the windshield and the

footwell are fixed in place. Only the fan switch is used to regulate the air flow.

Center and side nozzles

The air flow from the center and side nozzles

can be varied by pivoting the nozzle inserts and by adjusting the vents.

A lever attached at the side of the nozzles

provides continuous control for the air flow to the side and center nozzles.

The heater works only when the engine is

running. Maximum heating output and

fast defrosting can be obtained only after the engine has reached operating temperature.

Servomotor-controlled air mixing valves au-

tomatically mix the cold and warm air. The temperature inside the vehicle (tempera-

ture sensor behind the screen mask) and

outside the vehicle (temperature sensor jn the wheel box) are used for quick identification of temperature fluctuations and control

of the servomotor.

With sudden fluctuations in temperature, the

automatic system regulates the control of warm air, fresh air, and, if the air conditioner compressor has been switched on, the sup-

ply of cooling air until the preset inside tem-

perature is reached.

The air conditioner works only when the en-

gine is running, The higher the engine rpm,

the more intensive the cooling effect. Air from inside the car is drawn through the

evaporator for cooling and then reenters the car interior through the air outlets.

Proper operation of the air conditioner is guaranteed only if the windows and roof are closed and the outlet nozzles at the side and

the center are fully opened.

Automatic climate control

This system automatically controls the air flow distribution and the temperature level

inside the car according to the occupants

wishes. The distribution and mixture of cool

and warm air is electrically regulated and

kept constant, regardless of weather condi-

tions.

"AC" pressure switch

When the weather is warm, supplying of fresh air is not always enough to attain the

desired temperature within the car.

First set the temperature desired using the

temperature lever. Then switch on the air

conditioner by pressing the AC switch in the center console (arrow).

If no cooling of the air is required in transitional or colder seasons, the air conditioner should not be switched on due to consider-

ations of fuel economy.

If the vehicle has been standing for a fairly long time in intense sunlight, it is recommended that the inside of the vehicle be

thoroughly ventilated by opening the car win-

dows and switching on the air conditioner.

When the air conditioner is switched on, ad-

ditional cooled air reaches the glove compartment through a nozzle.

In damp weather it is recommended to switch on the air conditioner, even if the outside temperature is low. This dehumidifies

the air and prevents the windshield from fog-

ging up.

Important notes:

Temperature control - upper lever

Supply of outside air and fan switched

• The air conditioner operates only with the engine running.

• When the air conditioner is switched on, at least one airoutlet vent must be opened, since otherwise the vaporizer can ice up. The condensate forming during operation of the air conditioner escapes through openings at the bottom of the vehicle.

• The air conditioner must be switched on briefly at least once a month to lub-

ricate the seals and bearings of the air conditioner compressor and the expansion valve. This is particularly important in the winter when the air conditioner is not needed. The outdoor

temperature must be above 32° F/0° C.

• Whenever the air conditioner does not function properly, e. g. no cold air es-

capes even though the unit is switched on, switch it off and immediately see

your Porsche dealer.

The following controls make possible optimum adjustment of the unit to your individual air conditioning desires.

The lever provides continuous control for the

temperature in the passenger compartment.

Shoving it to the right raises the temperature.

The value on the temperature scale corres-

ponds to an average inside temperature. No automatic temperature control takes

place in program settings and

Gearshifting

manual transmission

Reverse Reverse should only be selected after the

vehicle has come to a complete stop.

The clutch pedal must be depressed several seconds before shifting into reverse; only then move the gearshift lever to the left, over-

coming the spring resistance, and to the

front.

Both back-up lights come on when the transmission is put into reverse (with ignition on).

The gear positions are illustrated in the dia-

gram. If you wish to shift from 1st gear into Re-

verse, the gearshift lever must first be

brought into the Neutral position and then shifted into Reverse. This is necessary because of the reverse gear lock-out mecha-

nism.

For smooth shifting, observe the following shift points which apply to standard gear ratios only:

Maximum downshifting points

5th to 4th gear

135 mph/215 km/h or 4800 rpm 4th to 3rd gear

100 mph/160 km/h or 4900 rpm 3rd to 2nd gear

70 mph/115 km/h or 4700 rpm 2nd to 1 st gear

45 mph/ 75 km/h or 4300 rpm

Minimum upshifting points

1st to 2nd gear 15 mph/24 km/h or 2000 rpm

2nd to 3rd gear 25 mph/40 km/h or 2200 rpm

The Porsche transmission with servo-lock synchronisation permits rapid and precise shifting of gears. When changing gears

make sure that the clutch pedal is fully depressed to the floor, and that the gearshift lever is completely engaged. The engine

speeds for the individual gears are listed on this page.

3rd to 4th gear 40 mph/64 km/h or 2500 rpm

4th to 5th gear 48 mph/77 km/h or 2300 rpm

Please observe all local and national speed limits!

Controls for automatic transmission

The individual driving ranges are selected automatically depending on

• selector lever position

• speed

• accelerator pedal position

The position of the gear shift lever lights up

in the instrument cluster display field whenever the vehicle lights or ignition are switched on.

Remember the following basic rules:

Apply the parking brake or foot brake before selecting a driving position. When the selector lever is in a driving position, the car may creep even at idle speed. Therefore, do not

release the parking brake or foot brake until you are ready to move.

Do not accelerate while selecting a driving position. At this time the engine must run at idle speed so that no undue stress will be placed on the automatic clutches in the

transmission.

Do not step on the accelerator until posi-

tive contact has been made.

Under no circumstances may the selector lever be moved from a driving range to N

while the car is travelling at speeds in ex-

cess of 40 km/h (25 mph) - see "Towing, Tempostat".

If the selector lever is unintentionally moved

into Neutral (N) while driving, take your foot off the accelerator pedal and wait until the engine speed has dropped to idle before selecting a driving position.

Never shift into reverse (R) or Park (P)

when the car is in motion.

Never get out of the driver's seat when the engine is running and the selector lever is not

in the " P" position. Move the selector lever

to "P" and apply parking brake.

Always make sure the selector lever is in the

"P" position when checking under the hood. Otherwise, any increase in engine speed

may set the vehicle in motion, even with the

parking brake applied.

A driving position must never be used for

holding the vehicle at rest uphill. Always use

your foot brakes when stopped on inclines.

WARNING While driving with the automatic speed

control set (at speeds above 30 mph or 50 km/h), do not bring shift lever into the Neutral position to prevent excessive engine rpm.

Starting the engine

is only possible when the selector lever is in Neutral or in Park (N or P). As long as one of the driving positions is engaged a safety switch prevents the engine from being started.

Driving the automatic transmission

The Automatic Transmission has 4 forward gears and one reverse. In driving positions

D, 3 and 2 the Automatic Transmission

changes gears automatically while driving. The push button in the selector lever pre-

vents inadvertent selection of a lower range. The button must be pressed to select 1, R and P. At speeds of more than 15 km/h (10

mph), a hydromechanical lock prevents

selection of R or R To avoid damaging the

engine, do not under any circumstances exceed the engine speeds listed below when selecting a lower driving range:

From D to 3 4250 rpm or 190 km/h (118 mph) From 3 to 2 3700 rpm or 110 km/h ( 68 mph)

Position D

is the driving position normally used for city and highway driving. It ranges from zero to top speed, and all four gears shift automatically depending on driving speed.

Position 3

is to be used for mountain driving or slow driving, when towing a trailer and also when you want to make use of the engine's braking effect. In "3", the first, second and third gears will engage automatically.

Page 59

Position 2

WARNING

Position P — Parking

This position is intended for driving conditions in which it appears advisable to remain

in 1 st or 2nd gear (e. g. when climbing or descending extreme gradients and towing a

trailer on mountain roads). Since the trans-

mission does not shift past 2nd gear, the

braking effect of the engine is increased.

The reverse position R

Reverse position should be selected only when the car has come to a full stop and the engine is running at idle speed.

The back-up lights come on automatically when you engage Reverse (with ignition on).

Emergency starting

Should the engine fail to start see

"Emergency starting with jumper cables" or consult your authorized Porsche dealer.

Do not start or tow the car without ATF in the transmission, as this will result in serious damage to transmission and torque converter.

Putting the car in gear

With the parking brake or foot brake set, shift

into the range you wish to use, usually posi-

tion D. To accelerate, release the brake and

depress the accelerator pedal.

Do not release the brake before you are prepared to move, because power is transmitted to the wheels as soon as a driving range is engaged.

Selecting a driving position while driving

is easy. Simply release the accelerator pedal and move the selector lever from the position you are into the position you want. Then step on the accelerator again.

WARNING

Do not shift to a lower driving position

until vehicle speed has dropped below the specified limits. Engine speed will suddenly increase and may cause engine damage and loss of vehicle control.

Stopping

When stopping temporarily, at traffic lights for example, it is not necessary to move the selector lever to Neutral. Simply apply the

brakes. To start again release the brake and accelerate.

When parking your car, apply the parking

brake first, and then move the selector lever to position P. To do this, depress the button and push the lever through R to P. The trans-

mission is then mechanically locked. Park

may only be engaged when the car is stationary.

Do not remove the key from the ignition steering lock until you have parked the car, because removal of the key locks the steering wheel.

Shift out of the Park position, before releas-

ing the parking brake.

When the car is parked on a steep hill, shift-

ing out of Park may be a little harder. This is due to the weight the car exerts on the trans-

mission.

Position N — Neutral

Shift to this position for standing with brakes applied.

Never use Neutral for coasting downhill. You may lose control over the car because of reduced braking and cause serious damage to the transmission when a driving range has to be selected.

Page 60

Maneuvering

Accelerator pedal position

When alternating between forward (D)and reverse (R) (for instance, while maneuvering

the car into a tight parking space), only shift

into Reverse or Drive when the car has come to a full stop and the engine is running at idle speed.

Stuck in snow, mud or sand

When alternating between Drive and Reverse in an effort to free the vehicle, depress

the accelerator pedal lightly while the trans-

mission is in gear, and release the ac-

celerator pedal while shifting. Do not race

the engine and avoid spinning the wheels.

Do not repeat "rocking" back and forth with wheels spinning at high engine speed and heavy throttle, as serious damage may be caused in the automatic transmission and other critical parts.

• Under moderate acceleration in the partload range, upshifts are effected at low speeds for the sake of economy and quietness.

• Under full acceleration, the upshift points slide to higher speed ranges.

• To achieve optimum acceleration (for

overtaking), the accelerator pedal must

be pressed down past its point of resis-

tance at full load (kick-down). The trans-

mission can shift down to a lower gear,

depending on selector-lever position and

roadspeed. When engine speed in-

creases, the transmission shifts up into the next gear.

Be careful when using the kickdown on slippery roads. Rapid acceleration may cause skidding.

As soon as you release the pedal from the

kickdown position the next higher gear can

be automatically engaged.

If you cannot free the vehicle after a few "rocking" attempts, call for help or a tow truck.

Please observe all local and national

speed limits.

Exercise extreme caution when

working under the engine hood

The engine compartment of any motor ve-

hicle is a potentially hazardous area. If

you are not fully familiar with proper re-

pair procedures, do not attempt the adjustments described on the following pages. This caution applies to the entire

vehicle.

• Only work on your vehicle outdoors or in a well ventilated area.

• Ensure that there are no open flames in the area of your vehicle at any time when gasoline fumes might be present. Be especially cautious of such devices such as hot water heaters which ignite a flame intermittently.

• Before working on any part in the engine compartment, turn the engine off and let it cool down sufficiently. Hot engine compartment components can burn skin on contact.

• Even after the engine has stopped, the

radiator fan may continue running until temperature of the coolant has dropped to a certain level. Therefore, never touch the fan blades as they will rotate spontaneously when the thermostat

turns the fan on, even with ignition off.

• Be alert and cautious around engine at all times while the engine is running.

• If work has to be done with the engine running, always set the parking brake, and make sure the shift lever is in either Neutral or Park.

• Exercise extreme caution to prevent

neckties, jewelry or long hair from get-

ting caught in the fan blades, the drive

belts, or any other moving engine parts.

• Your Porsche is equipped with a transistorized ignition system with breakerless distributor. When the ignition is on, high voltage is present in all wires connected with the ignition system; therefore, exercise extreme caution when working on any part of the engine while the ignition is on or the engine is running.

• Always support your car with safety stands if it is necessary to work under-

neath the car. The jack supplied with

the car is not adequate for this pur-

pose.

• When working underneath the car without safety stands but with the wheels on the ground, make sure the

car is on level ground, that the wheels are blocked, and that the engine cannot be started.

REMOVE THE IGNITION KEY.

• Do not smoke or allow an open flame around the battery or gasoline.

• Keep a fire extinguisher in close reach.

• Incomplete or improper servicing may cause problems in the operation of the car. If in doubt about any servicing, have it done by your authorized Porsche dealer or any other properly equipped and qualified workshop.

• Improper maintenance during the warranty period may affect your warranty

coverage.

Page 63

Engine oil

It is normal for your engine to consume oil.

The rate of oil consumption depends on the

quality and viscosity of oil, the speed at

which the engine is operated, the climate,

road conditions as well as the amount of di-

lution and oxidation of the lubricant.

Because of these variables, no standard rate of oil consumption can be established, but drivers should expect an increased oil con-

sumption at high speeds and when the en-

gine is new.

• The engine in your vehicle depends on

oil to lubricate and cool all of its mov-

ing parts. Therefore, the engine oil should be checked regularly and kept at the required level.

• Make it a habit to have the engine oil level checked with every fuel filling.

• Lack of sufficient engine oil may lead

to severe engine damage.

• The oil pressure warning light is not an

oil level indicator.

The oil level should be between the "max" and "min" marks on the dipstick. If the oil

level drops below the "min" mark, a fault

message appears in the information system display when the ignition is switched on. Top up the engine oil.

Checking oil level

To get a true reading, the car should be on

level ground. After turning off the engine,

wait a few minutes for the oil to return to the

oil sump.

1. Pull out dipstick and wipe it dry with a clean cloth or paper towel.

2. Reinsert dipstick; push it in all the way down for an accurate reading.

3. Pull dipstick out again. The oil level is correct if it is between the "max" und "min" marks on the dipstick.

4. If oil level is below "min" mark, or not showing on dipstick, add oil immediately.

The difference between the two marks is about 1 .6 U.S. qt. or 1 . 5 Liter.

Should the engine oil level be too low, the central warning light and the engine oil

level warning light will flash as soon as the ignition is turned on (see "central warning light system"). Do not start the engine but add oil immediately or contact your Porsche dealer.

See "Cautions"

Adding engine oil

Only add the amount of oil that is needed. The correct oil grade and viscosity recom-

mendation is given under "Engine Oils".

1. Remove oil filler cap (arrow).

2. Top up with quality oil labeled "API Ser-

vice SF or SE".

3. Check oil level with the dipstick - upper mark should not be exceeded.

4. Replace cap and tighten.

WARNING The oil filler cap and dipstick must be se-

cure to avoid oil spills and resulting fire

hazard.

Page 64

WARNING

Changing engine oil

Changing oil and filter

High quality multi-grade oils are suitable for all year round driving. Seasonal oil changes are therefore not necessary. Only if multigrade oils are not readily available, a single-

grade oil of the correct viscosity can be used. Specifications of the various oils to be used are detailed under "Filling Capacities and Engine Oil". The use of oil additives is

not recommended by Porsche.

• When removing oil drain plug with your fingers, keep your arms as high as possible. This will prevent hot oil from run-

ning down your arm. Wear eye protec-

tion.

• Always use a new gasket when reinstalling the plug. Do not over-

tighten the plug.

Before changing the engine oil yourself,

make sure that the disposal of the engine oil and the oil filter as special wastes is carried out in the proper manner. Do not dump it on the ground, into open streams or down sewage drains. Your zoning regulations or environmental rules will tell you how you can dispose of it. Should the disposal of old engine oil present a problem,

we suggest that you have your oil changed at your dealer or at a service station.

Oil change intervals specified in the Warranty & Maintenance booklet accompanying the

vehicle apply to normal operating conditions

and must be adhered to, including intervals

for oil filter change.

If you drive mostly short distances, or if you

operate the vehicle in dusty areas, or under

predominantly stop-and-go traffic conditions, or when temperatures remain below freezing for extended periods, the engine oil

should be changed more frequently.

With the engine at operating temperature

and ignition off.

Remove the engine guard before working at

the bottom of the engine.

1. Loosen and remove oil filler cap.

2. Loosen oil drain plug (arrow) on oil pan and allow oil to drain completely.

3. Loosen oil filter element with appropriate

wrench and remove.

4. Lightly coat new filter seal with oil.

5. Screw on new filter element until seal just contacts the crankcase. Only hand-

tighten according to filter manufacturer's

instructions on container or filter element.

6. Clean oil drain plug and replace, using a

new gasket. Do not overtighten the

plug.

7. Fill the crankcase with the required

amount of engine oil labeled "API Service SF or SE" (see "Filling Capacities").

Do not overfill.

8. Reinstall oil filler cap and tighten securely.

9. Run engine at various speeds for 3 - 5 minutes and check for leaks. Check the oil level with dipstick. Top up if necessary.

See "Cautions".

Engine oils

FOR THIS

LABEL

Use only engine oils which meet the specifi-

cations designated by Porsche. Your

Porsche dealer will be glad to advise you on

the correct type of oil for your engine. These oils can be intermixed.

Since, however, each brand of oil has a spec-

ial composition, you should, if possible, use the same oil brand if it becomes necessary to top up between oil changes. Porsche en-

gines have long intervals between oil

changes. You can make best use of these

long oil change intervals by using multigrade oils or multigrade fuel efficient oils since these are largely independent of seasonal fluctuations in temperature.

If your vehicle is used frequently in stop - and go traffic in winter, the engine will not always be properly warmed up. Condensation from

products of combustion may accumulate in the oil. In this case, it is advisable to change the oil in spring so that your engine once again has a 100% efficient engine oil.

Engine oil performance class

Engine oil is not only a lubricant, but also

serves to keep the engine clean, to neutralize the dirt which penetrates into the engine through combustion and to protect the engine against corrosion. To perform these functions, the oil is provided with additives which have been specially developed for

these functions. So-called mineral oils are

produced directly from crude oil.The oils can

be further refined (hydrocrack) or totally converted through a number of chemical processes (synthetic oils). These oils are structurally more efficient and require fewer addi-

tives than simple mineral oils. The efficiency of an oil is expressed, for

example, by the API classifications which are divided into categories "S" and "C". The degrees of quality are expressed by final letters

in alphabetical order. The requirements for

Porsche engines are API class SE/CC to SF/ CD.

Viscosity

Like all liquids, engine oil is viscous when cold, and thin-bodied when warm. The viscosity of an oil is expressed by its SAE class.

For cold viscosity (measured at temperatures below 0° C) the SAE class is given as a number and the letter "W" (as in winter); for hot viscosity (measured at 100° C) the

SAE class is given only as a number. The viscosity of an oil is, therefore, always

the same if it has the same number of an SAE class.

E.g.: A 10 W-30 oil and a 10 W-40 oil have the same viscosity when cold (below 0° C); when hot (at 100° C) the oil with the number 30 is thinner than the oil with the number 40.

Single-grade/multigrade oils

Oils with two viscosities are called multigrade oils; oils with only one viscosity are termed single-grade oils.

Single-grade oils can only be used for the narrow temperature range identified by their SAE number; multigrade oils cover a wider temperature range (see chart).

Fuel efficient oils

Fuel efficient oils require low viscosity at low

temperatures and high thermal stability at

high temperatures.

As high-performance oils, these oils are

manufactured only as synthetic or hydrocrack oils at present.

Manual transmission oil

The transmission oil has to be changed at the intervals listed in your Maintenance

Schedule.

Hypoid oil SAE 75 W 90 labeled "For Service API/GL5 or Mil-L 2105B" must be used for the manual transmission (also for limited

slip differential). Also see "Filling Capacities".

We recommend that you have the transmis-

sion oil changed at your Porsche dealer, who

has the required lubricants and the neces-

sary filling equipment.

If you suspect an oil leak in the transmission,

have your dealer check it out immediately.

Automatic transmission fluid

The torque converter and the transmission

are lubricated with Automatic Transmission Fluid (ATF). The final drive requires hypoid oil SAE 90 only.

Do not tow the car or run the engine with-

out ATF in the transmission. The automatic transmission may be dam-

aged by even a tiny speck of dirt, only a clean funnel or spout must be used when

adding ATF.

Checking the ATF level

The ATF should be checked at the intervals

listed in your Maintenance Schedule. A correct ATF level is very important for the proper

functioning of the transmission. The reading should be done when the ATF is

warm, with the engine idling, the selector

lever in Neutral and the parking brake applied.

The level of the ATF can be checked visually through the transparent reservoir, located at the rear end of the transmission housing. You

have enough ATF, if the fluid level is between

the MAX and the MIN mark on the reservoir.

The level should never be above or below

these two marks.

Should the fluid level in the transparent reservoir drop below the MIN mark or rise above

the MAX mark, do not just add or drain ATF.

Have your dealer check and correct the cause promptly.

In the event of a noticeable loss of ATF,

contact your dealer immediately.

Changing the ATF

The ATF has to be changed at the intervals

listed in your Maintenance Schedule. When refilling, the level must reach the mark below the MIN mark. Also see "Filling

Capacities".

Page 67

Windshield washer fluid reservoir

The transparent fluid reservoir is located in the right rear in the engine compartment, in front of the expansion tank (see illustration). As clear water is normally not adequate to

keep your windshield and headlights clean,

add a cleaning solution to the water.

To assure that the windshield washer and the

headlight washer (where applicable) sys-

tems also function at freezing temperatures,

anti-freeze/cleaning solution must be added to the water beforehand. Follow the instructions on the can for the right amount to be

used.

Do not use engine coolant antifreeze or

any other solution that can damage the car paint.

Cooling system

For year round driving, anti-freeze is added

at the factory for temperatures down to:

-23° F/-300 C for U.S.

-40° F/-400 C for Canada Because of its anti-corrosion properties,

antifreeze should also remain in the cooling

system for summer operation. Cooling system capacity and specified anti-freeze and water ratios are listed under "Filling

Capacities".

Use any quality phosphate-free anti-freeze

containing ethylene glycol, available at your

Porsche dealer. Anti-freeze other than

specified by Porsche for aluminium en-

gines and radiators may cause corrosion

of the cooling system, leading to engine

overheating and damage.

Only for topping up coolant, a small amount of anti-freeze containing ethylene glycol and phosphates may be used if recommended.

The anti-corrosion properties and the antifreeze consistency will diminish gradually. We recommend renewing the coolant mixture at least every 2 years.

WARNING

Even after the engine has stopped, the

radiator fan may continue running until temperature of the coolant has dropped to a certain level. Therefore, never touch the fan blades as they will rotate spontaneously when the thermostat turns the fan on, even with ignition off.

Checking coolant level in expansion tank

A correctly functioning cooling system re-

quires only minor care. The coolant level should be checked from time to time, and

always before going on a longer trip. The expansion tank with filler cap opening

is located in the right rear of the engine com-

partment (see illustration). Since the expan-

sion tank is transparent, it is not necessary to unscrew the filler cap.

When the engine is cold, the coolant level

should reach the manufacturing seam on the

expansion tank. When the engine is warm, the coolant level will be above the manufacturing seam.

Page 68

Since the closed cooling system loses al-

most no coolant, topping up is normally not

required. An obvious loss of coolant indicates leakage. The fault will be indicated by a fault message in the information system display. Top up the coolant and contact your dealer.

WARNING

• Do not open the filler cap when the en-

gine is hot because of the danger of scalding. Allow the engine to cool

down. Protect your hands, arms and

face.

• Using a thick rag, open the cap care-

fully and only enough to allow excess

pressure to escape before removing

the cap.

To avoid damage to the engine, only add

cold antifreeze and cold water to the cool-

ing system when the engine is also cold.

A warm engine should only be topped up if the coolant level has dropped appreciable

below the manufacturing seam. Too much added coolant will escape through the pres-

sure cap when coolant warms up.

For more details see "coolant temperature

gauge and coolant temperature warning

light".

Winter operation

At the beginning of the winter season, have

the coolant checked for anti-freeze concentration.

The ratio between water and anti-freeze,

necessary to prevent freezing, depends on

the anticipated outside temperatures. The

ratios can be taken from the mixing chart listed under "Filling Capacities" or from the

container of the antifreeze manufacturer.

Increasing the anti-freeze in the coolant further than shown on the container is not only uneconomical, it is also detrimental to engine cooling.

Intensive windshield cleaning

system reservoir

The reservoir is located in the engine com-

partment beneath the windshield.

To prevent damage and discoloration to paintwork, you should use only "Porsche Special Silicone Remover". Other cleaning agents are not suitable for intensive cleaning, but can, if this special cleaning agent is not obtainable, be added to the water of the washer system in the mix ratio stated by the manufacturer. "Porsche Special Silicone Remover" is safe against frost down to -25° C.

Page 69

Power steering fluid reservoir

The reservoir is located in the engine com-

partment on the left side.

To check fluid level...

1. Remove cap from reservoir.

2. With engine running at operating temperature, the fluid level should meet the mark on the reservoir. If necessary, top up

with ATF Dexron®.

3. Reinstall cap and make sure that sealing ring is seated correctly.

If the engine is not running, power assisted steering is no longer effective. You can continue to steer the car but more effort will be required to turn the steering wheel.

Changing air cleaner filter element

A dirty air cleaner not only reduces engine

performance, but can lead to premature engine wear. The filter element must be replaced at the intervals listed in your Mainte-

nance Schedule. If driving is mostly done in areas where the air is very dusty, the air cleaner should be checked and cleaned frequently — perhaps daily.

1. Detach air intake hoses from air cleaner housing. Make sure that each hose stays connected to the toothed belt covers.

2. Loosen rubber fasteners and remove top of filter housing together with filter ele-

ment.

3. Clean filter housing with lint-free rag and install new filter element.

4. Reattach air intake hoses to air cleaner housing.

WARNING The paper filter element must never be

cleaned or soaked with gasoline, clean-

ing solvents or oil. Doing so may cause a fire or explosion and result in serious personal injury.

Page 70

Brake fluid reservoir

The brake fluid reservoir is located in the en-

gine compartment.

The brake fluid reservoir has three cham-

bers: one for each of the dual brake circuits, and one for the clutch.

Check the brake fluid level regularly. Since

the reservoir is transparent, the fluid level

can be checked without removing the filler cap. The fluid level should always be be-

tween the MlN and MAX marks. To add brake fluid, unscrew the cap. The

vent bore in the cap should be kept clean.

Should the fluid level drop below the MIN

mark, the brake fluid warning light comes

on and a fault message appears in the in-

formation system display. Pull off the

road, stop the engine and add brake fluid immediately or contact the nearest Porsche dealer to have the cause located

and corrected.

WARNING

• Every 2 years the brake fluid has to be replaced. See your Warranty & Maintenance booklet.

• If brake fluid must be added to the reservoir, use only new and unused DOT

3 or DOT 4 brake fluid that meets SAE

specification J 1703 and conforms to Motor Vehicle Safety Standard 116.

• Do not use any other brake fluid or brake fluids that have absorbed mois-

ture from the open air, or brake fluid that is dirty. It may cause premature wear or unreliable braking action.

• Do not add or mix DOT 5 silicone type brake fluid with the brake fluid in your

vehicle as severe component corrosion may result. Such corrosion could

lead to brake system failure.

• The brake warning light does not indi-

cate brake fluid level. Check fluid level

between regular maintenance services.

• Brake fluid is poisonous. Brake fluid is also harmful to the paint of your vehicle.

Checking refrigerant level

Check the refrigerant level in the reservoir at least once a year because the fluid diminishes gradually during operation.

Turn on the air conditioner and observe refri-

gerant level through sight glass (arrow) in the reservoir. Occasional bubbles are normal. Foam or a constant stream of bubbles indicate that the system does not contain enough refrigerant. In case the system requires recharging, con-

tact your Porsche dealer. He has qualified

personnel and the necessary equipment.

Page 71

Fuel filler cap

The fuel filler cap is located under the flap in the rear quarter panel behind the right rear wheel.

When putting the cap back on the fuel filler

neck, be sure cap is securely seated. Twist cap counter-clockwise, until it stops with an audible click.

We recommend you turn off the engine when filling the fuel tank.

Fuel tank capacity

Fuel tank capacity is listed under "Filling

Capacities"

Porsche does not recommend the use of

fuel additives.

If you lose your fuel filler cap, replace it im-

mediately with a cap of the same design to reduce the possibility of a fire in a collision.

Fuel recommendations

Your Porsche is equipped with a catalytic

converter and must use UNLEADED FUEL ONLY.

Minimum octane rating is 95 RON/85

MON "Premium unleaded fuel" (90 CLC or AKI). Federal law prohibits use of leaded fuel in this vehicle.

Regular unleaded fuel with a minimum octane rating of 91 RON/ 82 MON (87 CLC or AKI) can be used temporarily, due to a built-

in knock control, if premium unleaded fuel is

not available. In this case avoid full throttle

operation.

The use of UNLEADED FUEL ONLY is criti-

cally important to the life of the catalytic converter. Deposits from leaded gasolines will

ruin the converter and make it ineffective as

an emission control device. Cars with a catalytic converter have a smal-

ler fuel tank opening, and gas station pumps

have smaller nozzles. This will prevent acci-

dental pumping of leaded fuel into cars with a catalytic converter.

Unleaded fuels may not be available outside the continental U.S. and Canada. Therefore, we recommend you do not take your car to

areas or countries where unleaded fuel may

not be available.

Octane ratings

Octane rating indicates a gasoline's ability to

resist detonation. Therefore, buying the cor-

rect octane gas is important to prevent en-

gine "knock".

The RON octane rating is based on the re-

search method. The CLC (U.S. Cost of Living Council octane rating) or AKI (antiknock index) octane rating usually displayed on

U.S. gasoline pumps is calculated as re-

search octane number plus motor octane

number, divided by 2, that is written as:

The CLC or AKI octane rating is usually lower than the RON rating:

95 RON equals 90 CLC or AKI

WARNING

Do not use any unleaded fuel with octane

ratings lower than 95 RON or 90 CLC or AKI.

Never carry additional fuel in portable

containers in your car. Such containers,

full or partially empty, may leak, cause an

explosion, or result in fire in case of a col-

lision.

Page 72

Gasolines containing alcohol

Gasoline containing alcohol is available at gas stations in some areas. The gas pump may not be labeled to identify that alcohol is present in the gasoline. If it is labeled, it may not identify what amount and type(s) of alcohol are used. We recommend you do not use fuels where the alcohol content cannot be identified.

Gasolines containing methanol

Do not use fuels containing methanol

(methyl alcohol, wood alcohol). The use of

fuel containing this type of alcohol can result

in vehicle driveability and performance problems and may damage critical parts of your

vehicle's fuel and emission control systems.

Gasolines containing ethanol

A mixture of unleaded gasoline and ethanol

(ethyl alcohol, grain alcohol) is sold in some areas. This mixture is sometimes called "Gasohol". You may use gasohol in your

Porsche, provided it contains no more than

10 % ethanol, and the octane requirements for your vehicle are met. However, we strongly recommend switching back to

gasoline without ethanol, if you experience any of the following problems with your vehi-

cle:

• Deterioration of driveability and performance.

• Substantially reduced fuel economy.

• Vapor lock and non-start problems, especially at high altitude or at high tempera-

tures.

• Engine malfunction or stalling.

Continued use of gasohol under these conditions may cause costly damage to the fuel system and the emission control system of

your vehicle.

Fuel economy

Fuel economy will vary depending on where, when and how you drive, optional equipment installed, and the general condition of your car. A car tuned to specifications and correctly maintained, will help you get maximum fuel economy.

• Have your vehicle tuned to specifications.

• Fuel injection should be adjusted to specifications.

• Spark plugs should be clean, properly gapped and fire efficiently.

• Air cleaner should be dirtfree to allow

proper engine "breathing".

• Battery should be fully charged.

• Wheels should be properly aligned.

• Tires should be inflated at correct pressures.

• Keep a light foot on the gas pedal.

• Drive smoothly, avoid abrupt changes in speed as much as possible.

• Avoid jack rabbit starts and sudden stops.

• Do not drive longer than necessary in the lower gears. Shifting up early helps to save fuel.

• Avoid unnecessary idling. Turn the engine off.

Page 73

• Prolonged "warm up" idling wastes gas. Start the vehicle just before you are ready

to drive. Accelerate slowly and smoothly.

• Any additional weight carried in the vehi-

cle reduces fuel economy. Always keep

cargo to a minimum and remove all unnecessary items.

• Organize your trips to take in several errands.

• Use air conditioner only when needed.

• All electrical equipment contribute to increased fuel consumption.

The E P A estimated m.p.g. i s to be used for comparison purposes, actual mileage may be different from the estimated m. p.g., depending on your driving speed, weather conditions and trip length. Your actual highway mileage will probably be less than the estimated m.p.g.

Please observe all local and national speed limits.

Operating your Porsche in other countries

Government regulations in the United States and Canada require that automobiles meet specific emission regulations and safety standards. Therefore, cars built for the U.S. and Canada differ from vehicles sold in other

countries.

If you plan to take your Porsche outside the

continental limits of the United States or

Canada, there is the possibility that

• unleaded fuel may not be available;

• unleaded fuel may have a considerable lower octane rating. Excessive engine knock and serious damage to both engine and catalytic converter could result;

• service may be inadequate due to lack of proper service facilities, tools or diagnos-

tic equipment;

• replacement parts may not be available or very difficult to get.

Porsche cannot be responsible for the mechanical damage that could result be-

cause of inadequate fuel, service or parts

availability.

If you bought your car abroad and want to

bring it back home, be sure to find out about

shipping and forwarding requirements, as well as current import and customs regulations.

Roof racks

Normal commercially available roof racks

cannot be fitted. If an original Porsche rack

(as available hitherto) is fitted, the permissible roof load is 35 kg (77 lbs).

With the "New Porsche Roof Transport System" you can transport a wide variety of

sports and hobby equipment, up to a roof load of 75 kg (165 lbs).

There are many different racks to choose from. Your Porsche dealer will be glad to advise you on the versatility of the "New Roof Transport System".

To ensure minimum noise, maximum comfort and economy and a desirable level of

safety when driving with an unloaded roof

rack, you should not exceed a maximum

speed of 180 km/h (110 mph).

When the roof rack is loaded, the recom-

mended maximum speed depends on the nature, size and weight of the load. You

should not, however, exceed a speed of 140

km/h (85 mph) at any time. Make sure that the load is carefully mounted. Secure it additionally by locking the roof transport system.

Car care instructions

WARNING

Washing and waxing

Regular and correct care helps to maintain the value of your car and is also a precondition for the New Vehicle Warranty and the Anti Corrosion Warranty.

Your authorized PORSCHE dealer has spec-

ially developed car-care products from the

PORSCHE program available either singly or as complete car-care sets. He will be

pleased to help you select suitable products. Whether you use PORSCHE products or

other commercially available cleaning agents first make sure of their correct application.

The Porsche paint finish is of a high quality baked synthetic enamel. The color and enamel type designation are indicated on

the "paint number sticker". When buying touchup paint, always give the paint and the

car's identification numbers to your dealer.

A well-cared for Porsche can look like new for many years. It all depends on the amount

of care the owner is willing to give the car.

• Cleaning agents may be poisonous.

Keep them out of the reach of children.

• Observe all caution labels.

• Always read directions on the container before using any product.

• Most chemical cleaners are concentrates which require dilution.

• Do not use gasoline, kerosene,

naphtha, nail polish remover or other volatile cleaning fluids. They may be toxic, flammable or hazardous in other ways. Only use spot removing fluids in well ventilated areas.

• Do not wash, wax or dry the vehicle with the engine running.

• Do not clean the underside of chassis, fenders, wheel covers, etc., without protecting your hands and arms as you may cut yourself on sharp-edged metal parts.

• Moisture and road salt on brakes may affect braking efficiency. Test the brakes after each vehicle washing.

The paint on your Porsche is very durable but

must be protected from losing its luster due to outside influences. Therefore, wash and wax your Porsche often. The longer the dirt

is left on the paint, the greater the risk of damaging the glossy finish, either by

scratching if the dirt is rubbed into the paint,

or simply by the chemical effect dirt particles

have on the paint surface. Do not wash or

wax in direct sunlight. Do not use hot water. Lukewarm to cool water is kinder to the paint.

Pamper your Porsche! Wash it by hand! The

mechanical brushes in an Automatic Car Wash may not reach every angle of the vehi-

cle, and some tracks may cause damage

to the underbody.

Use plenty of water, a car-wash and wax so-

lution and a soft sponge or a soft bristle hose

brush. Begin by spraying water over the dry surface to remove all loose dirt before apply-

ing the car-wash and wax solution. Use

plenty of water to rinse the vehicle off. Wipe everything dry with a chamois to avoid water spots.

Page 75

To guard against corrosion from the inside

out, clean drain holes on the bottom of doors, tail gates hatches, etc., after each

washing. Then wipe dry thoroughly. Also in-

spect all weatherstrips to make sure they do

not allow water to enter the body panels. Do not aim water jet directly at door, hatch

or rear lid locks. Tape the key holes to prevent water from seeping into the lock cylinders. Water in lock cylinders should be removed with compressed air. To prevent locks from freezing in the winter, squirt glycerine or lock

de-icer into the lock cylinders. Do not use any

solution that can damage the body paint.

The underside of the vehicle picks up dirt

and road salts used to keep streets and highways free of snow and ice. To guard against

corrosion, it is important to remove mud, de-

bris and road salt from the underside with a

powerful jet of water. Be sure to include the wheel housings, bumpers, muffler, tailpipe and brackets. This should be done twice a year and is best accomplished after the vehi-

cle has been driven through a heavy rain. Let

engine and exhaust system cool down before washing.

Waxing is not really needed when you have

used a car-wash and wax solution. If you do

not use a car-wash liquid with wax, apply

wax to preserve the natural shine of the body

paint. To obtain a long lasting finish, apply

hard wax. Wax again if water remains on the surface in large patches instead of forming

beads and rolling on.

Exterior

Care of the finish

Oils contained in the paint are the most im-

portant ingredients contributing to the elasticity of the finish. Because these oils gradually diminish, due to weather and similar causes, they must be replenished through

regular and proper care of the finish. Given

proper care, the original finish will retain its

luster for many years. Ask your dealer for ap-

proved cleaning agents and preservatives.

The use of polishes is recommended only

after it becomes evident that the normal preservatives no longer accomplish the job.

Dull finishes and plastics

Plastic pans, such as light bulb lenses, decorative stripes, panels, bumpers, etc., will come clean during car washing. Should additional cleaning or spot removal be necessary, use a soft brush or cloth soaked with a

mild detergent solution. Then rinse

thoroughly and immediately with clear water.

Do not use anything which could mar the

plastic or dull finished surface, such as wax or polish, abrasive detergents or chemical cleaning solvents.

Metal trim

Bright or black anodized trim will come clean

when you wash the vehicle. To protect the trim, use car wax.

Touch-up paint

Your dealer has touch-up paint for minor scratches and stone chips. Scratches should be touched up soon after they occur, to prevent corrosion. If corrosion formation

becomes visible, however, a simple touchup job will not suffice. The affected surface

must be smoothed with sand paper and covered with an antirust primer, before restoring the painted finish.

Tar or oil

Do not allow tar or oil to remain on the paint.

Remove as soon as possible with a cloth soaked with a special paint cleaner. If you do not have a tar or oil remover, you may substi-

tute with turpentine. After applying a clean-

ing fluid, always wash with a lukewarm soap water solution and apply a new wax coat.

Insects

Remove as soon as possible with a lukewarm soap/water solution or apply insect remover.

Tree sap

Remove with a lukewarm soap/water solu-

tion. Do not allow tree sap or bird droppings to harden on the paint.

Page 76

Windows

Keep silicone spray off the windshield to

avoid wiper smear in rain.

Generally, highway dust that settles on the

outside of the windshield contains material worn from tires and oil residues. On the inside surfaces of the windshields, particularly

in strong sunlight, there are build-ups of dust from the interior decor. These build-ups are

reinforced by pollution in the air brought in with the fresh air supply. Use a luke-warm soap/water solution or a window cleaning agent for the inside and outside. If a chamois

is used for polishing the glass, it should ex-

clusively be used for that purpose. To assure that windshield washers also func-

tion during freezing temperatures, anti-

freeze must be added to the washer fluid reservoirs before-hand. It is advisable to use

window washer solvent with anti-freeze all year round. Follow directions on the can for the right amounts to be used. Do not use

engine coolant anti-freeze or any other solution that can damage the paint.

In vehicles with Sekuriflex windshields, the plastic coating on the inside of the

windshield must not have gummed labels

put on it or be cleaned using abrasive

agents or dry methods. If very dirty, it can

be cleaned with normal drug store alcohol. Make certain that the plastic coating is not damaged in cleaning by hard

obiects such as jewelry or wristwatches.

Do not remove ice on the inside of the windshield by any means except warm air from the defroster nozzles. Do not use any deicer sprays, scratching tools, or scrapers!

A foil base must be applied to the windshield

prior to application of any labels or stickers such as those used for state registration or inspections. Failure to utilize foil base be-

tween sticker or label and the Sekuriflex

coating will result in damage to the Sekuri-

flex coating. Three foil bases were included

in the glove compartment of your vehicle and additional foil bases may be ordered from any Porsche dealer.

Instructions:

1. Clean the windshield in the area for application.

2. Cut the base of the foil to the required size. Round off the edges.

3. Pull off the protective film.

4. Spray the gummed side of the foil base and the windshield with a soap solution (distilled water and liquid soap or greasefree detergent in a mixing ratio 10 :1).

5. Apply the foil base to the windshield and spray it once again.

6. Any liquid and bubbles under the foil base must be brushed out using a flexible plas-

tic scraper.

7. Dry the windshield using a soft cloth.

8. Install label/sticker on the foil base.

When removing the label/sticker or the back-

ing foil, first spray the foil with a soapy solu-

tion (see point 4).

Wiper blades

Always loosen frozen wiper blades from

glass as they may tear otherwise.

Remove all wiper blades periodically and clan them thoroughly with an alcohol base cleaning solution. Use a sponge or soft cloth and wipe lengthwise.

Weatherstrips

To seal properly, weatherstrips around hood, windows, doors, etc. must be pliable. To retain flexibility of the rubber, spray with silicone, coat with talcum powder or

glycerine to retain flexibility of the rubber and to protect against freezing in the winter.

Light alloy wheels

To preserve the decorative appearance of the. light aluminium castings, some special

care is necessary. Aside from road dirt and salt sprays, brake dust will exert corrosive effects.

If left on too long, brake dust can cause pit-

ting. Wash the wheels with a sponge or hose

brush every other week. Road salts should

be removed weekly with an acid free clean-

ing solution.

The acid free cleaning solution must not

have a pH value greater than 10 (see explanation), in case of doubt, it is recommended to

check with the manufacturer of that particu-

lar cleaner.

Page 77

If the pH-value of the cleaner is incorrect,

the protective coating on the wheels may

be destroyed. We recommend PORSCHE

cleaner for light-alloy wheels.

Every three month (after regular cleaning) the

wheels should be coated with petroleum

jelly. Rub it in firmly with a soft cloth. Never

use abrasive or metal polishing cleaning agents.

Explanation of pH value

The pH value is a measurement for the hy-

drogen-ion concentration in a liquid. This

value tells if the liquid reaction is sour (acid)

or alkaline (base).

At a pH value of 7, the reaction of the liquid is

neutral (that is, chemically clean water), it is not an acid or alkaline. Acids have a pH value under 7, the strength of the acid increases with

a lower pH value. Alkaline lies between a pH

value of 7 and 14, the strength of the alkaline

increases with higher pH values.

For example: a mineral water mixed with carbon dioxide has a pH value of 6 - 6.5, reac-

tion is also light sour. Battery acid in com-

parison has a pH value of 1. or

the pH value for normal soap solution is 8 -

9, but the soap solution for a dishwasher is approximately 12.5, this would not be suitable for wheel cleaning.

The protective coating of the rims may be destroyed by chemical attack if a cleaner with an incorrect pH value is used.

Remember that moisture and road salt on

brakes may affect braking efficiency. Test

the brakes after each car or wheel wash.

Interior

Glass

Use the same cleaning agents as for the ex-

terior and polish dry with a soft cloth or

paper towel.

Fabric

Use a vacuum cleaner or a soft bristle brush

to remove dust and loose dirt from carpet-

ing, upholstery, headliner and other trim. Dirt

stains can usually be removed with a

lukewarm soap water or an all purpose

cleaner solution, or a dry foam cleaner. For

greasy, oily and other stubborn stains, use a spot remover. Do not pour the liquid on the fabric. Dampen a clean cloth and rub carefully, starting at the edge and working inward.

Seat belts

Keep belts clean. Very dirty belts may not re-

tract properly. Do not remove belts from the vehicle to be cleaned. Do not use chemical

cleaning agents, bleach or dyes. They contain corrosive properties which will

weaken the webbing. Do not allow inertia

reel safety belts to retract before they are completely dry.

For cleaning, use a mild soap water solution.

Let belts dry out thoroughly and away from direct sun light.

Plastic, vinyl and leatherette

Use a clean, damp cloth or sponge to keep

this trim free from dust. For other soilage,

use a lukewarm all purpose cleaning solution

or a mild saddle soap for vinyl and leather trim. Remove water spots and soap traces with a clean, damp cloth or sponge. Use a

clean, soft cloth to rub dry.

Grease, tar or oil stains can be removed with

a clean cloth or sponge soaked with all pur-

pose cleaner or with a solvent type vinyl or

leather cleaning agent.

Occasionally apply a colorless vinyl or

leather preservative to retain the material's

luster and pliability.

Leather and leather trim

To keep leather seats and trim beautiful and soft, they should be cleaned and cared for regularly. Clean leather with a soft, white woolen cloth and a mild soap water solution. Do not use chemical or abrasive cleaning agents. Do not let moisture seep through perforated surfaces to safeguard against corrosion and cracking from underneath. After cleaning, apply the PORSCHE leather preservative to all dry surfaces with a clean and soft woolen cloth.

Page 78

Corrosion protection

The engine compartment, as well as all engine, transmission, front and rear axle assembly surfaces have been treated with wax

based coating at the factory for protection

against corrosion.

When washing the engine compartment, only use commercially available grease cutting solvents made especially for this

purpose. Carefully follow directions printed on the container by the manufac-

turer.

WARNING

Do not apply additional undercoating or rustproofing on or near the exhaust mani-

fold, exhaust pipes, catalytic converter or

heat shields, with the engine running, the substance used for undercoating could overheat and cause a fire.

Engine compartment

If it becomes necessary to steam clean or otherwise wash the engine compartment, the wax based protective coating is usually

lost. It is, therefore, important to reapply this

protective coating to all engine compart-

ment panels, flanges, cavities, seams and engine assembly surfaces.

Chassis

The lower body shell of your Porsche is thoroughly protected against corrosion.

However, it is recommended to have the underbody inspected twice a year. Any detected damage to the undercoating, due to

road hazards, should be repaired promptly. Oil based protective sprays must not be applied. Only tar or wax based anti-corrosion protectors are compatible with the factory applied undercoating. Before application, road dirt and oily substances must be

removed.

Whenever the lower body shell, axle, transmission or engine assemblies are repaired, the lost anti-corrosion coating of the affected surface should be renewed.

Let your Porsche dealer advise and assist you.

Exercise extreme caution when

working under the engine hood

The engine compartment of any motor ve-

hicle is a potentially hazardous area. If

you are not fully familiar with proper re-

pair procedures, do not attempt the

adjustments described on the following

pages. This caution applies to the entire

vehicle.

• Only work on your vehicle outdoors or in a well ventilated area.

• Ensure that there are no open flames in the area of your vehicle at any time

when gasoline fumes might be present. Be especially cautious of such devices such as hot water heaters which ignite a flame intermittently.

• Before working on any part in the en-

gine compartment, turn the engine off and let it cool down sufficiently. Hot engine compartment components can

burn skin on contact.

• Even after the engine has stopped, the radiator fan may continue running until

temperature of the coolant has drop-

ped to a certain level. Therefore, never

touch the fan blades as they will rotate

spontaneously when the thermostat

turns the fan on, even with ignition off.

• Be alert and cautious around engine at all times while the engine is running.

• If work has to be done with the engine running, always set the parking brake, and make sure the shift lever is in either Neutral or Park.

• Exercise extreme caution to prevent

neckties, jewelry or long hair from get-

ting caught in the fan blades, the drive

belts, or any other moving engine

parts.

• Your Porsche is equipped with a transistorized ignition system with breakerless distributor. When the ignition is on, high voltage is present in all wires connected with the ignition system;

therefore, exercise extreme caution when working on any part of the en-

gine while the ignition is on or the engine is running.

• Always support your car with safety stands if it is necessary to work underneath the car. The jack supplied with

the car is not adequate for this pur-

pose.

• When working underneath the car without safety stands but with the wheels on the ground, make sure the car is on level ground, that the wheels

are blocked, and that the engine cannot be started.

REMOVE THE IGNITION KEY.

• Do not smoke or allow an open flame around the battery or gasoline.

• Keep a fire extinguisher in close reach.

• Incomplete or improper servicing may cause problems in the operation of the

car. If in doubt about any servicing,

have it done by your authorized Porsche dealer or any other properly equipped and qualified workshop.

• Improper maintenance during the warranty period may affect your warranty

coverage.

Tool kit

Car jack

WARNING

The tool kit is a lift-out tray fitted into the rear cross wall of the car. To remove or replace

the tray, turn both holding knobs 90° (ar-

rows).

The tool kit contains tools needed for minor

emergency road side repairs or adjustments.

Regulations in some countries require additional tools. Details should be obtained before leaving for a foreign country.

The car jack is located underneath the lug-

gage compartment, together with the collapsible spare tire. The tire is covered by a lid

with a quick release catch.

• Use the jack only for changing a wheel. Never jack up other vehicles or other loads with it.

• Follow all warnings and instructions found in this manual for changing a

tire.

• The jack must never be used as a support to work underneath the vehicle. If

the jack is accidently dislodged, you or

bystanders could be seriously injured,

when working under the vehicle, always use safety stands specifically designed for this purpose.

Page 82

Tires/Wheels

The original equipment tires on your Porsche

comply with all applicable Federal Motor Vehicle Safety Standards.

For your driving safety remember the following:

• Wheel rims and wheel bolts are matched to fit your Porsche.

• If you intend to use other than original

equipment wheels, be sure that they con-

form to Porsche specifications for your

model.

• The use of wheel rims and wheel bolts that do not meet specifications of the

original factory installed equipment will affect the safe operation of your vehicle.

• Before you plan on exchanging wheels,

or snow tires already mounted on wheel rims, consult your Porsche dealer. He has

the technical information necessary to

advise you which wheel rims and wheel bolts are compatible with the original fac-

tory installations.

Tire pressures

WARNING

Incorrect tire pressures cause increased

tire wear and adversely affect road hold-

ing of the vehicle, leading to loss of con-

trol.

Always use an accurate tire pressure

gauge when checking inflation pressures.

Do not exceed the maximum tire inflation pressure listed on the tire sidewalk (Also refer to "Technical data"). Cold tire infla-

tion pressure means: when a car has not

been driven for at least 3 hours or less than 1 mile. Never let any air out of warm tires to meet cold tire pressure specifications.

Tire traction WARNING When driving on wet or slushy roads, a

wedge of water may build up between the tires and the road. This phenomenon is

known as aquaplaning and may cause

partial or complete loss of traction, vehicle control or stopping ability. Reduce speed on wet surface.

Tire life

Tire life depends on various factors, i.e.,

roads, traffic and weather conditions, driving

habits, type of tires and tire care.

Inspect your tires at least every 2000 miles

or 3000 km for wear and damage. If you

notice uneven or substantial wear, wheels might need alignment or tires should be balanced or replaced.

Tires must always remain on same side of vehicle.

After changing, adjust tire pressure and tor-

que wheel nuts diagonally to 94 ftlb (130

Nm). See "Changing wheels".

Tire wear

The original equipment tires on your Porsche

have built-in wear indicators. They are

molded into the bottom of the tread grooves and will appear as approximately 1/2 in (12 mm) bands when the tire tread depth is down

to 1/16 of an in (1.6mm). When the indicators appear in two or more

adjacent grooves, it is time to replace the

tires. We recommend, however, that you do

not let the tires wear down to this extent.

Worn tires cannot grip the road surface prop-

erly and are even less effective on wet roads.

In the United States, state laws may govern

the minimum tread depth permissible. Fol-

low all such laws.

WARNING

Do not drive with worn tires or tires showing cuts or bruises as they may lead to sudden deflation.

If you notice that tires are wearing unevenly, consult your Porsche dealer. Uneven wear may not always be due to improper wheel alignment. It can be the result of individual driving habits such as cornering at high speeds. If the tire pressure is not checked and adjusted regularly, abnormal tire wear can also occur.

Page 83

Tire care WARNING

• Avoid damaging tires and wheel rims. If you must drive over a curb or other obstacle, drive slowly and at an obtuse

angle. Frequently check tires for uneven wear and damage.

• Remove imbedded material.

• Replace worn or damaged tires immediately.

• Replace missing valve dust caps.

• Keep oil, fuel, brake fluid, etc. away

from tires.

• Keep tires inflated correctly.

Tire damage

Regularly check tires for imbedded material,

cuts, punctures, cracks and bulges (side

wall).

In case of tire damage, where it is uncertain

whether there is a break in the ply with all its

consequences or tire damage caused by

thermal or mechanical overloading due to a

loss of pressure or any other prior damage,

we recommend that the tire be replaced for

safety reasons.

If one faulty tire on an axle is replaced it should be noted that the difference in tread depth on one axle must not exceed 30 %.

Performed visual inspection.

Parking at the curb

Hard impacts against curbs (or traffic islands) are dangerous and may cause hidden

tire damage which is not noticeable until

later. (Danger of accidents at high speeds).

Tires have a memory!

WARNING:

It you must drive over a curb, drive slowly and, if possible, at right angles. Exercise care when parking along curbs.

Tire replacement

The tire makes and types specifically

mentioned in your vehicle papers are

binding, when changing to different tires,

be sure to observe the applicable regulations in your country. If in doubt, contact your Porsche dealer or Porsche importer of your country.

If you do not use a Porsche recom-

mended replacement tire, make sure that you purchase your new tires from a reputable tire specialty dealer and that the dealer complies with all manufacturers warnings for those tires.

Before mounting new tires, check with your Porsche dealer about the current re-

lease status.

For tires with ZR quality standard, there are

currently no final standards concerning tire

strength at speeds above 240 km/h.

For this reason, only use tire makes and

types tested by Porsche. Tires should be replaced at least on one axle

at a time. As a matter of principle, only tires of the same make and type should be combined. Mixed tires are not permissible.

Whenever you replace tires, make certain

that you install new valves. Initially, new tires do not have their full traction. You should therefore drive at moderate speeds during the first 60 - 120 miles (100 - 200 km).

Have new tires mounted by an expert only.

Wheel balancing

A wheel should always be balanced after a

tire repair. Even with regular use a wheel can get out of balance, and should, therefore, be

balanced from time to time. Unbalanced

wheels may affect car handling and tire life.

When fitting tires already mounted on rims,

ensure that the colored wheel bolt is closest to the valve. Always screw the lockable wheel nut onto this bolt. When removing,

mark the direction of rotation on each wheel, e.g. FR, FL, RR and RL This precaution ensures that the wheels will be remounted in the same position, thus obviating the risk of

imbalance. When balancing light alloy wheels, use only

adhesive balancing weights supplied through the Porsche parts service.

Page 84

Wheels

If you intend to use other than original equipment wheels, be sure that they conform to Porsche specifications for your model.

Check with your Porsche dealer regarding

the correct wheel specifications for type and

model year.

Removing and storing tires

The driving direction should be clearly

marked on all tires before removing them for

storage. This is to make sure that they are

mounted and run in the same direction as be-

fore. When remounting, put tires with the

most tread depth at the front. Have tires/

wheels balanced as soon as possible. The supposition that tires become long

wearing due to storage and age is unfounded. Chemical additives, which make the rubber elastic, loose their effectiveness

in the course of time and the rubber perishes. Therefore, the tires, especially

the collapsible spare tire, should from time to time undergo a visual check. For this, pump up the collapsible spare tire.

Under no circumstances should tires be

older than 6 years.

The age of the tire can be seen from the

"DOT" code number. If, for example, the last

three numbers read 128, this means it was

produced in the 12th week of 1988.

Store tires in a cool and dry place.

Snow tires

For a better grip on snow and ice use radial

M+S tires or snow tires with studs. Check with your local Motor Vehicle Bureau for possible restrictions.

Radial ply M+S tires should be inflated with

the same cold tire inflation pressures re-

quired for the regular radial ply tires. However, do not exceed the maximum tire infla-

tion pressure listed on the tire sidewalk

Snow tires should have the same load ca-

pacity as original equipment tires and should

be mounted on all four wheels. Snow tires with studs should be run at moderate speeds when new in order to give the studs time to settle.

When fitting tires already mounted on rims,

ensure that the colored wheel bolt is closest

to the valve. Always screw the lockable wheel nut onto this bolt. When removing,

mark the direction of rotation on each wheel, e.g. FR, FL, RR and RL This precaution ensures that the wheels will be remounted in

the same position, thus obviating the risk of

imbalance.

WARNING Tires with badly worn treads and studs

are very dangerous. Make sure they are replaced immediately.

Do not drive a vehicle equipped with snow

tires at prolonged high speed. Snow tires do

not have the same degree of traction on dry,

wet or snowfree roads as a normal tire. Furthermore, snow tires wear rapidly under these conditions.

Snow tires do not fulfill their purpose if the tread depth is less than 5/32 in/4 mm. Comply

with all state and local laws governing

snow tire and tread depth requirements.

Snow chains

Should snow chains be necessary, they

must be mounted on the drive wheels

only.

Check with local authorities for possible re-

strictions.

Use only snow chains with fine pitch links,

so that enough space remains between the

chains and the inside of the wheel arches. Drive wheels must rotate freely with chains

mounted to prevent damage to body, axle or

brake components. Follow instructions issued by the supplier of the chains. Remove chains as soon as roads are free of ice and snow.

Page 85

Tire designations

Due to new speed and load ratings for radial tires, new designations have come into force for snow tires for your Porsche.

The designation to be used for ZR tires is e. g., 245/45 ZR 16 (Z = code letter for radial tires for speeds above 240 km/h.

Page 86

Collapsible spare tire

The spare tire is stored underneath the lug-

gage compartment cover. It is covered by a lid with a quick release catch. The car jack,

the electric air compressor kit and the tire

pressure tester are stored inside the wheel rim. This kit also includes a plastic cover for

the road wheel to keep luggage compart-

ment or car interior clean. Due to tread and space saver design fea-

tures of the collapsible tire, car handling may

be affected.

Therefore, do not drive more than 50 mph/ 80 km/h with moderate acceleration when using the collapsible spare tire. It is

for emergency use and short distances

only. Fitting the spare wheel at the front

improves handling of the car and reduces

wear on the tires. This applies for cars

equipped with locking differential, in par-

ticular. Only one collapsible spare tire

may be fitted to the car. Remount the original road tire as soon as possible.

Inflating the collapsible tire

WARNING

Do not overinflate your spare tire.

Inflate the collapsible tire with the electric air

compressor that comes with your Porsche.

Do not use other equipment!

1. Mount spare wheel before inflating the tire.

2. Attach hose of air compressor to tire valve and insert plug of electric cord into cigarette lighter socket.

3. The required tire pressure is 36 psi or

2.5 bar. Check pressure with tire pressure gauge.

4. Disconnect hose and electric cord and store air compressor.

5. Have flat road tire repaired and remounted on car at next service stop. Remember, the collapsible tire is for emergency

use and short distances only.

When the air is released from the collapsible tire, it will return to its original shape after

cooling down for several hours. Store collap-

sible tire in the luggage compartment.

The collapsible spare tire cannot be re-

paired or mounted with standard work-

shop equipment. Repair and remounting

must only be done by the tire manufac-

turer.

Tire tread depth

As required by law, the tread depth of the col-

lapsible tire is the same as that of the original equipment tire. Replace a worn collapsible spare tire in time.

If air compressor does not work

.. .Check if tobacco or any other foreign

matter is lodged in the cigarette lighter socket. Remove carefully with a wooden

pick. Do not use metal object to prevent

short circuit.

.. .Check if fuse is blown. Replace with new

equivalent fuse.

Maintenance of air compressor

The air compressor is maintenance-free. Do

not apply oil or any other lubricant.

The air filter should be cleaned periodically to assure maximum efficiency of the unit.

To unlock a wheel

1. Remove protective plastic cap from wheel nut.

2. Insert key all the way and turn left about 30°.

3. Remove lock sleeve together with inserted key.

Changing a wheel

WARNING - Failure to follow these instructions may result in serious personal

injuries to you or to bystanders.

Lockable wheel nuts

You can guard against wheel theft by instal-

ling lockable wheel nuts on your wheels. Each kit contains three keys and four wheel nuts with lock sleeve. The locking mechanism is identical for all four wheel nuts. When

taking the vehicle to your Porsche dealer or

to a workshop for wheel or tire service, re-

member to leave one key with the service at-

tendant.

In case of loss, duplicate keys cannot be

furnished by your Porsche dealer. Do not

leave these keys in the vehicle. Keep them in a safe place.

4. Replace protective plastic cap.

To lock a wheel

1. Remove protective plastic cap from wheel nut.

2. Insert key, turn it back 30° to right and re. move. Slide lock sleeve over wheel nut

until you feel it lock in.

3. Make sure that the edge of the lock sleeve rests firmly against base of wheel nut.

4. Replace protective plastic cap.

To avoid unbalancing the wheels, always fit the lockable wheel nut to the colored bolt beside the valve.

• If you have a flat tire, move a safe distance off the road. Turn the emergency flasher on and use other warning devices to alert other motorists.

• Passengers must not remain in the ve-

hicle when it is jacked up.

• Before you change a wheel, be sure the ground is level and firm. If necessary,

use a board under the jack to ensure that the jack does not sink into the ground.

• Set the parking brake and block the wheels opposite the flat tire on the other side of the vehicle.

• The jack is only to be used for chang-

ing a wheel. Do not use it as a support

to work under the car.

• Never jack the car up by the body or the bumpers.

Page 88

crosswise. When tightened crosswise,

the nuts will center the wheel correctly.

Make sure that the coloured wheel bolt is closest to the valve. Screw the lockable wheel nut onto this bolt.

6. Inflate the collapsible spare tire with the air compressor. Check pressure with tire pressure gauge.

7. To lower the car, turn the jack handle counterclockwise till tire touches ground.

8. Fully lower the vehicle and remove jack.

9. Firmly tighten the wheel nuts again in a crosswise pattern.

Sequence of operation

Loosen the wheel nuts about one turn. Do not yet remove the nuts.

Securely insert the car jack in the front

jack port located under the body. There

are two on each side; front and rear.

Do not raise the vehicle until you are sure

the jack is securely engaged.

3. To raise the car, turn the handle clockwise. Only raise the car as much as is needed to change the wheel.

4. Fully unscrew all wheel nuts, remove the wheel and put the collapsible tire on.

5. When the spare wheel is in position, reinstall the nuts and handtighten them

Correct tightness of the wheel nuts is important. Correctly tightened nuts should have a torque of 94 ft. lb. (130 Nm). This torque can

be obtained with the wheel nut wrench by any person of average strength. If in doubt about the correct tightness of wheel nuts,

have it checked with a torque wrench by your dealer or at a service station.

Page 89

Lifting vehicle

Lifting with car jack The jack ports are located below the front

and the rear of the doors underneath the

floor pan, hidden from view. WARNING

• Follow all warnings and instructions found in this manual for changing a tire.

• The car jack must never be used as a support to work underneath the vehicle. If the jack is accidentally dis-

lodged, you or bystanders could be

seriously injured, when working under

the vehicle always use safety stands specifically designed for this purpose.

• Jacking at any other place may damage the vehicle or may result in per-

sonal injuries.

The vehicle should never be lifted or

jacked up from underneath the engine oil

pan, the transmission housing, or the

front or rear axle. This could lead to seri-

ous damage. Lifting with workshop hoist or floor jack

Make sure there is sufficient clearance be-

tween pads and vehicle before driving vehi-

cle onto hoist, especially if the vehicle has a

large front panel or spoiler . The vehicle must be lifted only at the lift points for the car jack.

Take care to avoid damaging critical com-

ponents which are close to the lift points.

WARNING When removing components such as en-

gine block, transmission housing, fuel tank, wheels, front or rear axle, anchor ve-

hicle to hoist or add corresponding weights to maintain the center of gravity. Otherwise the vehicle might tilt or slip off the hoist, causing serious damage or personal injury-

Page 90

Fuses and relays

A failure in the electrical system may be

caused by a blown fuse or a faulty relay. The central fuse/relay board is located in the

passenger's footwell and protected by a

cover plate.

The use of the fuses and relays is shown

in a list on the floor board. Before replacing a fuse, turn off all electri-

cal components and the ignition; remove the key. Replacing a fuse or a relay with the engine running or the ignition on

could cause electrical shock.

When replacing a fuse, do not hold fuse

by its metal parts. In case of a repeated short circuit, the new fuse will burn out again, causing possible injury.

If a fuse blows repeatedly, do not keep on

replacing it. The cause of the short circuit or overload must be found. On no account should fuses be patched up with tin foil or

wire as this may cause serious damage elsewhere in the electrical system.

To replace a fuse...

1. Lift carpet in the passenger's footwell and

tilt up the protective cover plate from fuse/relay board.

2. In a blown fuse, the metal strip has

melted. In order to replace the fuse, it must be pulled from the spring clamp.

The tool for doing this is located at the top

left on the central electrical system. If there is doubt, or, for example, in the dark, the fuse can be tested by inserting it at the test point on relay XVI. If the fuse is defective, the diode in the relay does not

light up.

3. Carefully install new fuse. Use only fuses with the same rating as replacements!

4. Replace cover plate and carpeting.

It is advisable to always carry a few spare

fuses in the car.

Relays

Under the fuses, there are relay boards attached for various electrical switching functions. Testing and replacement of a defective

relay should only be done by an authorized

Porsche dealer. The relay for the rear window wiper is located

on the back left, under the tool plate, the time

relay for the seat heater is located under the seat.

If you need a circuit diagram, your Porsche dealer will be glad to help you.

However, in order to avoid damage to the electrical installation, we recommend having all work, including the installation of electrical accessories, done by your Porsche dealer.

Page 91

Battery-12 Volt

The battery is located underneath the collapsible spare tire in the luggage compartment. The battery is accessible after taking out the spare tire.

A replacement battery should always have the same rating as the original equipment

battery. Specifications are printed on the battery housing.

Before work is done on the electrical sys-

tem, the battery must be disconnected to

prevent short circuiting. First disconnect the negative ground wire at body (arrow) and then the positive cable. To reconnect

battery, reverse the procedure.

This precaution must also be taken before

charging with a rapid charger, as the alter-

nator may otherwise be damaged. Disconnecting the battery while the en-

gine is running will damage the alternator.

This also applies to cars equipped with a

battery main switch. Never drive the car with a disconnected

battery as this will damage the alternator.

If the battery is disconnected, the data for

the engine electronics stored in the control

unit are erased. When the battery is reconnected, the engine should be run for approx.

10 minutes to allow the control unit to re-acquire these data. During this period, the engine may idle unevenly or too fast.

WARNING

• Do not lay tools or other metal objects

on the battery as they could cause a short circuit across the battery termi-

nals.

• Do not expose the battery to an open

flame or electric spark. Hydrogen gas

generated by the battery is explosive.

• Do not let battery acid come in contact

with skin, eyes, fabric or painted sur-

" faces.

• If you get electrolyte, which is an acid,

in your eyes or on skin, immediately rinse with cold water several minutes and call a doctor.

• Spilled electrolyte must be rinsed off at

once with a solution of water and bak-

ing soda to neutralize the acid and pre-

vent damage to fabric and metal.

Checking the electrolyte fluid level

The electrolyte fluid level in your battery can

be checked by unscrewing and opening the filler vent caps of each cell. The fluid level should meet the indicator mark in each cell.

If necessary, top off with distilled water.

How often water must be added depends on

operating conditions and on the time of year.

Generally, the electrolyte level must be checked

more often in the summer than in the winter,

and more often when driving long distances.

Only fill up to mark, otherwise the electrolyte will overflow when the battery is being

charged and cause damage.

Battery care

• Battery should be securely mounted.

• Terminals and connections should be kept clean and properly tightened. Corro-

sion can be prevented by coating termi-

nals and connections with petroleum jelly

or silicone spray.

• Vent caps must be securely tightened to prevent spillage.

Winter operation

During the winter months, battery capacity

tends to decrease as temperatures drop. Ad-

ditionally, more power is consumed while starting and the headlights, heater, rear window defogger, etc., are used more frequently. Curtail unnecessary power consumption, par-

ticularly in city traffic or when travelling short

distances only. Let your Porsche dealer test the battery's capacity before winter sets in. A well charged battery will not only prevent start-

ing problems but will also live longer.

Page 92

Battery charging

Automotive batteries lose their efficiency

when not in use. The charge available in your

battery can be measured with a hydrometer. We recommend that battery voltage be tested by your Porsche dealer who has the

appropriate equipment. If the car is not dri-

ven for prolonged periods, the battery must

be charged at least every 6 weeks. A discharged battery allows rapid formation of sulfates, leading to premature deterioration of the plates.

WARNING

• Charge battery in a well ventilated area. Keep away from open flame or electrical spark. Do not smoke. Hydrogen gas generated by the battery is explosive.

• Electrolyte fluid that may spill during charging should be washed off with a solution of warm water and baking soda to neutralize the acid.

• If you get electrolyte in your eyes or on

your skin, immediately rinse with cold water for several minutes and call a doctor.

• Never charge a frozen battery. It may

explode because of gas trapped in the

ice. Allow a frozen battery to thaw out

first.

• Never use a fast charger as a booster to start the engine. This may seriously damage the vehicle's electrical system and the charger.

• Fast charging a battery is dangerous and should only be attempted by a competent mechanic with the proper

equipment.

Slow battery charging

WARNING

Heed all warnings and follow instructions

that come with your battery charger.

• Disconnect battery cables and remove

the battery.

• All vent caps should be open. If fluid level is low, it should be topped up to the full mark in each cell.

• Connect charger cables.

Charger cables must be connected POSI-

TIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-).

• Do not connect or disconnect charger cables while charger is operating.

• Switch on charger.

• Normally, a battery should be charged at no more than 10 percent of its rated capacity. Rated capacity of the battery in

your vehicle is listed on the battery housing.

• After charging, turn off charger and dis-

connect charger cables. When the electrolyte fluid has stopped "bubbling" in the cells, close the vent caps.

• Tighten the vent caps and reinstall bat-

tery.

Page 93

Emergency starting with

jumper cables

WARNING

• Improper use of booster battery to start a vehicle may cause an explosion.

• Lead-acid batteries generate explosive gases. Keep sparks, flames and

lighted cigarettes away from batteries.

• Do not charge a frozen battery, thaw it out first. Gas trapped in the ice may cause an explosion.

• No attempt should be made to jump start any vehicle with a low electrolyte

level in the battery.

• Check electrolyte level of each cell. If

necessary, fill with distilled water to

just above plates.

• Make sure the voltage of both batteries

is the same.

• The capacity (Ah) of the booster battery should not be lower than that of the discharged battery.

• Vehicle with discharged battery: turn off lights and accessories, remove key,

move lever to N or P and set parking

brake.

• Vehicle with booster battery should not be running. Disconnect ground cable.

• Remove vent caps from booster battery and discharged battery. Prefera-

bly lay a cloth over open vents to re-

duce explosion hazard.

How to use jumper cables

WARNING

• To avoid serious personal injury and damage to the vehicle, heed all warn-

ings and instructions of the jumper

cable manufacturer.

• Only jumper cables of adequate diameter cross-section and fitted with insu-

lated alligator clips should be used.

• The jumper cables must be long enough so that neither vehicles nor ca-

bles touch another.

• When connecting jumper cables, make sure that they cannot get caught in any

moving parts in the engine compartment.

Improper hook-up of jumper cables can ruin the alternator.

Always connect POSITIVE (+) to POSITIVE

(+), and NEGATIVE (-) to NEGATIVE (-).

1. Connect camp of plus-cable to positive (+) terminal of discharged battery.

2. Connect camp on opposite end of cable to positive (+) terminal of booster battery.

3. Connect camp of minus-cable to negative (-) terminal of booster battery.

4. Connect camp on opposite end of cable to a bare metal part of car with dis-

charged battery. Connect clamp as far away from battery as possible.

5. Start engine in the usual manner. If engine fails to start, do not continue to crank but

contact nearest workshop.

6. With engine running, remove jumper ca-

bles from both cars in exact reverse order: Steps 4 through 1.

7. Reconnect ground cable of booster battery.

A - Discharged Battery

B - Booster Battery

Do not try to start car by pushing or tow-

ing. Damage to the catalytic converter,

the transmission, and/or other compo-

nents of the car may result.

Page 94

Start assist connecting points sequence

On right side of engine compartment you will

find a positive (+) battery post (remote con-

nection).

First connect clamp at end of positive (+) cable to the remote connection in the en-

gine compartment (+ arrow). Then con-

nect clamp at other end of positive (+)

cable to the positive (+) terminal of the

booster battery.

Next connect clamp at end of negative (-)

cable to the negative (-) terminal of the

booster battery. Then connect clamp at other end of negative (-) cable to the engine compartment strut rod (- arrow).

caution: The cable clamps must not contact

each other, and the plus-cable leading to the

positive (+) post must not contact any metal pan of the car.

Caution: Do not try to start car by pushing or towing. Damage to the catalytic converter and other components of the car may result.

Replacing bulbs

To avoid short circuits, turn off the respective electrical components when changing light

bulbs.

Keep bulbs free of grease and dirt. Hold

them only with a clean cloth or soft paper. Headlights

Do not use chemical cleaning agents for the plastic lenses. Plastic lenses should only be cleaned with water or a mild soap/ water solution.

We recommend you keep an assortment of spare bulbs in the car.

When traveling abroad, remember that some countries require spare bulbs as part of the safety equipment.

1. Turn the ignition on.

2. Turn light switch to position 2 to raise the headlights.

3. Turn the ignition off.

4. Unsrew the 3 Phillips screws (arrows) and remove headlight cover.

5. Turn holder of defective bulb anticlockwise to limit stop and remove.

6. Unplug wires, replace bulb and reconnect the wires.

7. Reinstall bulbholder. Be sure that guide pins on bulb base fit into socket of reflec-

tor. Turn bulbholder clockwise to limit stop.

8. Check functioning of bulb and adjust headlights.

9. Reinstall headlight cover.
