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 demanding 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.

You will find helpful hints in this manual on how

to perform most of the checks listed on these pages. If in doubt, have these checks per-

formed by your Porsche dealer.

First things first

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

• Be sure tires are inflated correctly. Check 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 en-

gine 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 engine hood is locked safely.

• Replace worn or cracked wiper blades.

• See that all windows are clear and unob-

structed.

• 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 drivers seat...

On the road...

• Check operation of horn.

• Position seat for easy reach of controls.

• Adjust inside and outside rear view mirrors.

• Use safety belts.

• Check operation of foot and parking brakes.

• Check all warning and indicator lights with ignition on and engine stationary.

• Do not 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.

• Always drive defensively. Expect the unexpected.

• Use signals to indicate turns and lane changes.

• Turn on headlights at dusk.

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

• Reduce speed at night and during inclement 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 stopped or parked, always set the parking brake. 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.

• When stalled or stopped for repairs, 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.

Do not invite car theft!

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 lock the doors.

WARNING Always remove the ignition key,

especially if children are left unat-

tended in the vehicle. Unsupervised

use of any vehicle key may cause serious personal injury.

Do not leave your vehicle unattended with the key in the ignition lock. Take the key and lock the doors.

a Master key b Auxiliary key c Rear glove compartment key d Key for lockable wheel nuts

Keys

Three keys are supplied with the vehicle. The two master keys (black head) fit the ignition lock, door locks, luggage compartment lock, fuel filler cap lock and glove compartment lock.

The auxiliary key (read head) fits the ignition lock, door locks, luggage compartment lock and fuel filler cap lock.

WARNING Do not remove the key from the steering

lock while you are driving or as the car is

rolling to a stop. The steering column is locked 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 master and auxiliary keys makes unauthorized duplication of the keys virtually impossible. This means, however, that you yourself will not be able to get replacement keys cut, unless ordered from the manufacturer.

For vehicles equipped with lockable wheel nuts, four identical keys, four wheel nuts with lock sleeve, plus a standard wheel nut for the spare wheel, 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 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 record of your key numbers in your wallet together with your license.

Page 12

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.

Key light

One master key has 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 button is depressed.

• If you should lose a key, provide your Porsche dealer with the key number to obtain a duplicate key. Tell him whether you need a master or an auxiliary key.

The flashlight is powered by a 1.5 Volt button battery. When the beam begins to fade, replace the battery, because an old battery

may leak and damage your clothes.

Auxiliary

key

If your Porsche is equipped with an anti-theft alarm system, you will be given a duplicate set of the master S-key illustrated above instead of the "regular" master key. The alarm system can only be activated or deactivated with the S-key.

Functions for both S-key and auxiliary key are listed under "locking operations".

Attempting to open the doors, the rear lid or the engine hood by any other means or turning on the ignition when the alarm system is activated will produce an intermittent high noise for about 30 seconds.

The engine cannot be started while the alarm system is activated.

Keep the S-key in your personal possession at all times. Leave the auxiliary key only with an attendant when the car is being serviced.

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

Doors

Central door locking system

The central door locking system enables you to lock or unlock both doors simultaneously by operating one door lock.

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.

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.

With the ignition key in Pos. "1" or "2" both doors can be locked or unlocked by pressing 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".

To open doors from outside, pull the recessed door handle.

To open doors from inside, pull recessed handle "C" above armrest.

The armrests have a built-in storage compartment. 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 hatchback is opened. The light can also be turned on or off with the switch on the light housing.

dows 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.

Page 17

Front seats

The correct seating position is all-important for safe and fatigue-free driving.

For individual adjustment of the desired seating position, two 4-position switches permit infinitely variable electrical adjustment in a longitudinal and vertical direction as well as adjustment of the backrest inclination.

The rocker switches for the seat adjustment

are located at the outboard side of the seat.

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

1. Operate switch for 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.

Longitudinal adjustment Height adjustment, front Backrest adjustment Height adjustment, rear

Seat heating system

The seat heating system is turned on by means

of the key switch (A); it heats the seat pan and backrest. After approximately 15 minutes, a

time relay shuts off the heating automatically. You can also turn it off earlier by pushing the

key switch downward.

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 18

Manual operation

Should the electrical seat adjustment fail, you can use the hexagon socket-screw in the toolkit for longitudinal seat adjustment by turning

the servo-motor at the front end of the seat.

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

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.

Rear seats - luggage compartment

The backrests of the rear seats can be tilted forward to provide additional luggage space.

Unsnap the luggage compartment cover from the upright rear seat backrests and the rear cross wall.

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

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.

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

heed all of the following warnings and instructions.

• A combination lap-shoulder belt should

not be worn by a person less than 4' 11" or 1.5 m in height, because it would not be in its most protective position and,

therefore, may increase the possibility

of injury in an accident.

• Persons smaller than 4' 11" or 1.5 m in height and children who are able to sit upright by themselves should use one of the rear seating positions and the lap belt provided.

• For maximum safety and protection, we recommend that small children travel in the rear seats.

• When driving in foreign countries, remember that some require the wearing of safety belts by law.

• Do not strap in more than one person

with each belt.

• For maximum effectiveness, the lap belt

should be worn low across the pelvic crest.

• Do not wear shoulder part of belt under

your arm or otherwise out of position. This would increase the possibility of serious injury in case of an accident.

• 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 in-

terfere 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. This reduces the posibility of the tongue becoming a striking object in case of a sudden stop.

• Belts that have been subjected to excessive stretch forces in an accident must be replaced.

• If belts show damage to webbing, bindings, buckles or retractors, they should be replaced.

• If belts do not work properly, see your authorized 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.

Page 22

Safety belt warning system Inertia reel retractor

The combination lap/shoulder belt with inertia

reel locking mechanism adjusts automatically

to your size and movements as long as the pull

on the belt is slow.

An audio-visuel warning system is interconnected with the driver's safety belt.

Every time the ignition is turned on, the seat belts warning light in the center console will come on for about 6 seconds as a reminder to

buckle up. If the driver does not fasten the safety belt, the gong will also come on. The gong will go off as soon as the driver has buckled up.

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.

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

• Insert latch into buckle on inboard side of seat. Push down until it is securely locked 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 23

• To unfasten belt, push in release button on buckle. Belt 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 on doorpost.

Lap belts for rear seats

The belt with inertia reel locking mechanism adjusts automatically 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.

• To fasten lap belt, grasp latch on outboard side of seat and slowly pull across the pelvis. insert latch into buckle on inboard side of seat and push down until it is securely locked with an audible click. Pull belt to check. To unfasten belt, push in release button on the buckle.

• To store belt, allow belt to wind up as you guide latch to retractor.

To set the parking brake

Loudspeaker balance control

Parking brake lever (arrows)

Parking brake force is mechanically trans-

ferred to the rear wheels by means of cables.

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

Press in the release button (arrow) at the end of the lever as you pull the lever up. The parking 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 central warning light and the parking brake

light will go out after the engine is started and the parking brake is fully released (see "Central warning light system").

The volume of the loudspeakers in the door and in the rear of the vehicle can be balanced by turning the loudspeaker balance control knob (A), located next to the parking brake lever.

Hatchback release

Brakes

Brake pedal

Brake operation and brake warning light

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 safe stop.

WARNING

Failure of one brake circuit will impair the braking capability resulting in an increased 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 have it towed

to the nearest authorized Porsche dealer.

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 tra-

vel 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 intending to

brake. Overheating and wear of the brakes is the result.

• Before descending a steep grade, reduce 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 central warning light and the brake fluid warning light in the combination instrument will flash when the level in the brake fluid reservoir is too low (see "Central warning light system").

With correctly adjusted brakes, and a correct-

ly 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 increases 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.

Page 26

Brake booster

New brake pads or linings

Clutch

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 required to bring the car to a halt.

Moisture or road salt on brakes affects braking

WARNING Driving through water may reduce the trac-

tion. Moisture on brakes from road water or car wash or coating of road salt may affect braking efficiency. Cautiously apply brakes for a test. When the vehicle is driven on salted roads for extended periods, the brakes should be hosed down thoroughly about every 2 weeks. An automatic carwash 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 recommended

in your Warranty & Maintenance booklet.

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 kilo-

meters of normal city driving if fewer stops are realized.

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 rectification.

Always depress the clutch pedal fully when changing gears. Do not hold the car on a steep hill with the clutch pedal partially depressed. This may cause premature wear or damage.

Ignition/Starter Switch with Steering Lock

The steering is equipped with an anti-theft ignition lock.

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 elec-

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

2 Ignition on, steering unlocked. All electric

circuits are operational. With the engine stationary, the central warning light and all individual warning lights located in both combination instruments will light up for a bulb check. If the engine oil level is too low the central warning light will flash. (Lack of engine oil can only be checked with the dipstick, 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 central and individual warning lights should go out. The STOP LAMP will go out after depressing the brake pedal and the PARK BRAKE light after fully releasing the parking brake (see "Central warning light system").

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 steering,

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 your reminder to remove the key.

Starting Procedures

WARNING

• Fasten safety belts before driving off.

• 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 material.

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

Temperature sensors on the engine automat-

ically 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 temper-

atures, 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 restarting.

Do not let the engine idle to warm it up. After starting, accelerate gradually and maintain moderate speed. Avoid high rpm and full throt-

tle until the engine has reached normal oper-

ating temperature.

Stopping engine

Turn key back to position 0.

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 your 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.

Manual transmission:

Move gearshift lever to Neutral.

Automatic transmission:

Move gearshift lever to Neutral or Park.

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.

If the garage door opens or closes without your operating the garage door unit in your car, contact the dealer who installed the automatic garage door to have the frequency and/or coding of the garage door signal modified.

also on: tail lights

instrument illumination shift pattern illumination for automatic transmission selector lever

When you open the door while the lights are on, the gong will sound. It is your reminder to switch off the lights.

Instrument illumination control

With headlights on, the brightness of the instrument illumination can be adjusted by turning the thumbwheel on the left side underneath the instrument cluster.

With headlights on, the fog lights can be turned

on or off by depressing switch "A". The switch is illuminated when the fog lights are on.

Trip odometer

The trip odometer in the lower part of the speedometer can be turned back to zero by depressing switch "B".

Page 32

Manual transmissions

Tachometer

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 indicates 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 transmissions

Indicator system for position of gearshift

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 tachometer.

The display goes off when the key is removed

or when the vehicle lights are switched off.

Computer Assisted Shift Indicator System

(Manual Transmission only)

A computer continually evaluates vehicle data, such as driving speed, engine rpm, engine load and engine temperature.

When the CASIS arrow in the tachometer

lights up, it means the engine could operate

more economically. The light indicates that you can increase fuel efficiency by shifting into a higher gear. The CASIS light will go out when a higher gear has been engaged, when taking your foot off the gas pedal or when accelerating at a higher rate. In fifth gear the CASIS light is inoperative.

During maximum acceleration, the CASIS ar-

row light will only light up at a point where engine rpm is such that improved acceleration can be obtained by shifting into the next higher gear. This means the CASIS arrow does not

indicate any set shift point, but that the com-

puter calculated shift points depend on the way you drive. The arrow will light up at the

lowest speed range when cruising, and the highest speed range when accelerating with wide open throttle.

Page 33

How to use CASIS

|Q) High beam indicator light

Drive your Porsche shifting as you normally

would. As soon as the engine reaches uneconomical

load range, the CASIS light will remind you to

shift into the next higher gear to keep the engine at the same performance level but with lower fuel consumption.

You will get used to CASIS quickly and as a

result operate your Porsche with the CASIS arrow light coming on only now and then.

WARNING

Use CASIS to your best advantage but remember that traffic, road and weather conditions must always have priority when shifting gears or changing speeds.

Speedometer

The speedometer indicates driving speed per hour.

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

The upper odometer records total distance driven and cannot be turned back.

The trip odometer in the lower part of the instrument can be turned back to zero by de-

pressing the odometer reset switch on the

lower left side of the instrument cluster.

The blue light in the instrument cluster will light aup when the switch lever is pushed forward. The blue light will go out when switching to low beam.

Turn signal indicator light

The green 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.

Central warning light

The central warning light in the instrument cluster will light up or flash when a fault occurs in one of the vehicle's systems. (Refer to "Central warning system").

Page 34

Coolant temperature gauge and warning light

Needle in lower field - engine is cold

As long as needle is in lower field, avoid high speeds and high engine rpm, until engine has reached normal operating temperature. 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 upper field, especially at high engine loads,

but should return to "normal" when engine load is reduced.

Needle in upper field - warning

If needle enters the upper field, the engine is overheating. The central warning light will also come on. Reduce speed and engine rpm. If the needle does not return to the center field,

and the central warning light remains on, pull off the road, turn off the engine and let it cool down.

Coolant temperature warning light

If this light comes on, check whether the V-belt driven mechanical fan is working. If the fan is not working, the V-belt may be loose or broken.

The belt should be tensioned or replaced.

Do not continue to drive with a broken

V-belt.

On vehicles equipped with a factory installed air conditioner, also check whether the electric

fan in front of the air conditioner is working.

WARNING

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

tact.

• The air conditioner condenser fan is

electrically driven. It is switched on automatically by a thermostat when the coolant reaches 92° C/198" F. Even when the engine is turned off, the fan will continue running, until the coolant temperature has dropped to 87° C/189 F and until the engine itself has cooled down sufficiently. Therefore, never touch the fan blades as they will rotate spontaneously when the thermoswitch turns the fan on.

• Be careful if you have to remove the cap

from a hot coolant fluid reservoir (expansion tank). Protect your hands, arms and face against scalding. Use a thick rag and open the cap carefully one turn to allow excess pressure to escape before removing the cap.

If the electric fan is not working, there may be

a malfunction in the temperature sensor switch or in the electrical system. Check for a blown fuse.

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".

COOLANT

The warning light comes on when the fluid level in the expansion tank falls below the required minimum. Occasionally, the light may come on when starting the engine. As soon as the engine warms up, the coolant in the reservoir will expand, rise above the minimum level, and the light will go out. If the COOLANT

warning light remains on, top up immediately

and have the cooling system inspected for leaks.

For other details refer to "Cooling System".

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.

The central warning light and the warning lights

in the combination instrument light up for a

bulb check when the ignition is turned on. They

should go out as soon as the engine is started. Also see "Central warning light system".

Warning Lights

(see "Central warning light system")

BRAKE FLUID

Oil pressure gauge Oil pressure 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.

If the oil pressure should drop suddenly while you are driving, this light and the central warning light will flash. Pull off the road and stop the engine immediately. Check the engine oil level. If it appears to be normal, contact the nearest workshop.

The voltmeter shows the overall condition of the charging system. The needle should normally stay in the 12-14 volt range when the engine is running. A temporary drop below 12 volts when starting the engine is normal.

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, there may be a malfunction in the electrical system. 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.

The central warning light and the warning lights in the combination instrument light up for a bulb check when the ignition is turned on. They should go out as soon as the engine is started. Also see "Central warning light sys-

tem".

The warning light flashes when the brake fluid level falls below the required minimum.

BRAKE PAD The warning light comes on when a brake pad

is worn.

PARK BRAKE

The warning light comes on and stays on until parking brake is fully released.

ENGINE OIL

The warning light flashes if, with the ignition on, the engine stationary, and the vehicle on level ground, the amount of oil in the sumps is less than 1.59 U.S. gal. or 6 liters.

Do not attempt to start the engine! Add oil at once.

Automatic Speed Control

The automatic speed control allows you to maintain a constant cruising speed of 30 mph (50 km/h) or higher, without actuating the accelerator pedal. Any manual operation, such as accelerating, gearshifting or braking can be done independent of the automatic 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 to prevent excessive engine rpm.

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 removing the foot from the accelerator pedal.

Please observe all local and national speed limits.

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 automatic 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 the 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 automatic 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.

Switch lever for windshield wiper/ washer and headlight washer

This lever has 6 switch positions. The electric wiper system Is actuated by pulling the lever up or down to the following 4 positions:

0 wipers turned off

1 wipers on slow speed 2 wipers on medium speed 3 wipers on fast speed 4 wipers on intermittent speed

The intermittent wiper interval can be adjusted by turning thumbwheel "A" on the right side underneath the instrument cluster.

The electric washer system is actuated as follows:

5 Pull lever toward steering wheel to operate

windshield washer. Fluid can be sprayed into the windshield from any selected wiper speed position. When the ignition is switched on, the washer nozzles are heated, depending on the outdoor temperature.

6 Push lever toward instrument cluster to

operate headlight washer.

The headlight washer system operates only with the headlights on and raised.

Avoid running the wiper blades over a dry windshield to prevent scratching the glass. Spray on washer fluid first. A scratched windshield will reduce visibility.

Always loosen blades frozen to glass before operating wipers to prevent damage to wiper motor.

WARNING Worn or dirty wiper blades will reduce visi-

bility, making driving hazardous. Clean blades regularly to remove road film and carwash wax buildup. Use an alcohol base cleaning solution, a lint free cloth and wipe lengthwise.

Clean all inside and outside window glass regularly. Use an alcohol base cleaning solution and wipe dry with a lint free or a chamois cloth.

(seen from below)

Intensive windshield washer system (where applicable)

By depressing switch "B" on the right side underneath the instrument cluster, a supply of special intensive cleaning solution is pumped to the windshield. Heavy road dirt, silicone or insects can be removed quickly without smearing. The spray duration is controlled by a time relay to avoid excessive use of the special cleaner. The regular windshield wiper/washer system can then be operated to finish the cleaning process.

Page 41

The control function of the central warning light

system is divided into two major groups:

Central warning light system

This electronic warning system monitors the

most important functions of your Porsche for

increased safety and reliability of performance.

Should a problem arise, the central warning

system will inform you immediately.

The central warning light is located in the top

center of the instrument cluster. The indivi-

dual warning lights are divided between the

two combination instruments.

When the ignition is turned on, the central

warning light and all individual warning lights

will light up for a bulb check. If the engine oil

level is too low the central warning light will flash. (Lack of engine oil can, in comparison with all other functions, only be checked with the engine turned off, and with the vehicle on level ground.) As soon as the engine is started, the lights should go out. The STOP LAMP light will go out after the brake pedal has been depressed. The PARK BRAKE light will go out as soon as the parking brake lever is fully

released.

Should a problem arise, the central warning light will light up or flash, together with the respective individual warning light.

Group "A" - engine oil pressure

- engine oil level

- brake circuit (pressure) failure

- brake fluid level

Any of these malfunctions reported by the system must be corrected immediately.

Group "B" - brake wear (pads) indicator

- parking brake

- coolant level

- coolant temperature

- fuel reserve level

- windshield and headlight washer fluid level

- stop lamps

- tail lamps

- toothed belt tensioning

Any group "B" malfunction reported by the system should be corrected as soon as possible.

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 automatically mix the cold and warm air.

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 supply of cooling air until the preset inside temperature is reached.

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 conditions.

The temperature inside the vehicle (temperature sensor behind the screen mask) and outside the vehicle (temperature sensor in the wheel box) are used for quick identification of temperature fluctuations and control of the servomotor.

"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 considerations of fuel economy.

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 gua-

ranteed only if the windows and roof are closed

and the outlet nozzles at the side and the center are fully opened.

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 windows and

switching on the air conditioner.

When the air conditioner is switched on, addi-

tional cooled air reaches the glove compart-

ment 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 fogging up.

Page 47

Important notes:

• 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 lubricate

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.

Temperature control - upper lever

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 corresponds to an average inside temperature.

No automatic temperature control takes place in program settings I and

Fan speed control - rotary switch knob

The air volume is controlled by a 4-speed fan.

When the ignition is turned on, the fan automatically operates at low speed, even with the switch in 0 position. By turning the knob clockwise, fan speeds 1-4 can be selected to increase the air volume.

Program control - lower lever

There are several programs available in order

to adapt to individual needs with an automati-

cally controlled air conditioner:

Supply of outside air and fan switched off. For brief operation, e.g. when passing through disagreeable odors.

Air flow distribution only through side window and center air vents.

Air flow distribution through footwell outlets. The side and center vents can be opened optionally.

Air flow distribution through windshield and footwell outlets. The side and center vents can be opened optionally.

Air flow distribution through windshield outlets. The side and center vents can be opened optionally.

Automatic air flow distribution for heated

. . - air through windshield outlets and open

side window vents. Heating system and fan motor are automatically switched on maximum output and high speed for fast defrosting or defogging. At temperatures above 32° F/0° C the air conditioner compressor switches on automatically.

Page 48

Additional vaporizer for increased cooling output

In vehicles with increased cooling unit output, there is an additional vaporizer with a fan installed instead of the floor console.

When the air conditioner switch is pressed in,

and the air conditioner is turned on, the back vaporizer can be switched on by turning the

button at the left in the center console to the

right. Fan speeds from 1 to 3 can be adjusted.

Turning the button at the right to the right increases the cooling output from the rear vaporizer.

The inside air is drawn in through the rear grid, cooled, and circulated in the floor area. If the AC switch has not been pushed in, only circulation of the air is provided.

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 refrigerant 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, contact your Porsche dealer. He has qualified personnel and the necessary equipment.

Luggage Compartment

Protect your luggage and other belongings

from the sun and "inquisitive eyes" by us-

ing the snap-on luggage cover.

To prevent luggage and other objects from

sliding around while the car is in motion, you

can secure them with spider straps available through your dealer or other supply firms. The eyelets for this purpose can be found behind the rear bolster and on the luggage compart-

ment floor.

WARNING

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.

The "New Genuine Porsche Roofload Transport System" provides for maximum per-

missible weight loads of up to 165 lbs or 75 kg. Your Porsche dealer will be glad to advise you

which type of roofrack can best serve your individual needs and load carrying requirements.

Page 55

Reverse Reverse should only be selected after the

vehicle has come to a complete stop.

For smooth shifting, observe the following shift

points which apply to standard gear ratios only:

Gearshifting Manual Transmission

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.

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

If you wish to shift from 1st gear into Reverse, the gearshift lever must first be brought into the Neutral position between 4th and 5th gear and then shifted into Reverse. This is necessary because of the reverse gear lock-out mechanism.

Maximum downshifting points

5th to 4th gear

148 mph/237 km/h or 4300 rpm

4th to 3rd gear

111 mph/178 km/h or 4700 rpm

3rd to 2nd gear

80 mph/128 km/h or 4600 rpm 2nd to 1st gear

53 mph/85 km/h or 4300 rpm

Minimum upshifting points

1st to 2nd gear 15 mph/24 km/h or 1900 rpm

2nd to 3rd gear

25 mph/40 km/h or 2000 rpm

3rd to 4th gear 40 mph/64 km/h or 2300 rpm

4th to 5th gear

48 mph/77 km/h or 1400 rpm

Please observe all local and national speed limits!

Controls for

Automatic Transmission

The selector lever has 6 positions:

Start in Neutral or Park

The selector lever has a push button in the handle. The push button must be depressed when selecting the following positions:

From P to R

R to P N to R 3 to 2

The selector lever can be moved freely be-

tween the other positions.

The position of the gear shift lever lights up in

the tachometer display field whenever the ve-

hicle lights or ignition are switched on.

depress push button in handle

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. When the vehicle is standing still, wait for it to

switch to drive after selecting the gear. 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 positive contact has been made.

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 level is not

in the "P" position. Move the selector lever

' to "P" and apply parking brake.

Always make sure the selector level 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.

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.

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. Therefore, only shift down into driving position "3" when the speed is below 90 mph or145 km/h. It is not necessary to let up on the accelerator.

Page 57

Position 2

is needed on rare occasions. It should only be

used up to 75 mph or 120 km/h. In "2" the transmission will only shift into first or second gear and not shift into the third or fourth gear.

Only shift down into "2" when the car speed is below 40 mph or 65 km/h.

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).

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.

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.

Moving off Parking

With the parking brake or foot brake set, shift into the range you wish to use, usually position D. To move off, release the brake and accelerate.

WARNING 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 transmission is then mechanically locked. Park may only be engaged when the car is stationary. At driving speed above 10 mph or 15 km/h, a hydraulic lock prevents the driver from unintentionally moving the selector lever into position R or P.

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 releasing

the parking brake. When the car is parked on a steep hill, shifting

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

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 58

Maneuvering

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 transmission is in gear, and release the accelerator 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.

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

Accelerator Pedal

For good fuel economy we recommend smooth and even acceleration. Very fast, racy driving, alternating between full throttle and hard braking, raises the fuel consumption considerably. Also, tires and brake linings wear faster. It is more economical to drive smoothly and at a fairly constant speed.

Accelerator "Kickdown"

When depressing the accelerator pedal you will find resistance at the throttle position. By applying greater pressure the pedal can be

pushed beyond this point to the kickdown position. The transmission will now shift automatically into the next lower gear to give you max-

imum acceleration, and only shift up again after the engine has reached maximum speed in that particular gear.

Be careful when using the kickdown on

slippery roads. Rapid acceleration may cause skidding.

Please observe the following when applying the accelerator kickdown:

With the selector lever in D, you can apply the kickdown to make the transmission shift down

into third gear when driving below 120 mph or

195 km/h, into second gear when driving be-

low 70 mph or 115 km/h and down to first gear when driving below 25 mph or 40 km/h.

With the selector lever in "3", you can apply the kickdown to make the transmission shift down into the second gear when driving below 70 mph or 115 km/h and into first gear when driving below 25 mph or 40 km/h.

With the selector lever in "2", you can apply the kickdown to make the transmission shift down into first gear when driving below 25 mph or 40 km/h.

As soon as you release the pedal from the kickdown position the next higher gear is automatically engaged.

Please observe all local and national speed limits.

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 precautions 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 or in

Neutral.

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.

Engine Oil Consumption

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

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 dilution and oxidation of the lubricant.

WARNING

• Engine exhaust is dangerous if inhaled.

• Never start or let the engine run in a closed garage.

• Exhaust fumes from the engine 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.

Page 60

Fuel Economy

Operating Your Porsche in other Countries

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 speci-

fications.

• Spark plugs should be clean, properly

gapped and fire efficiently.

• Air cleaner should be dirtfree to allow prop-

er 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.

• 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 vehicle 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 consumers contribute to increased fuel consumption.

The published EPA mileage estimates may vary, depending on speed, weather and trip length. Your actual highway mileage will probably be less.

Please observe all local and national speed limits.

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 considerably 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 diagnostic equipment;

• replacement parts may not be available or

very difficult to get.

Porsche cannot be responsible for the mechanical damage that could result because 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.

Page 61

Fuel tank capacity

Fuel tank capacity is listed under "Filling

Capacities".

Porsche does not recommend the use of

fuel additives.

Fuel Recommendations

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 correct octane gas is important to prevent engine "knock".

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.

Your Porsche is equipped with a catalytic converter and must use UNLEADED FUEL ONLY. Minimum octane rating is 91 RON (87 CLC or AKI rating on U.S. fuel pumps).

However, Porsche recommends the use of 96 RON "Premium unleaded fuel" (92 CLC or

AKI).

The use of UNLEADED FUEL ONLY is critically 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 smaller fuel tank opening, and gas station pumps have smaller nozzles. This will prevent accidental pumping of leaded fuel into cars with a catalytic converter.

Unleaded fuels may not be available outside the continental U.S. and Canada. Therefore,

The RON octane rating is based on the research method. The CLC (U.S. Cost of Living Council octane rating) or AKI (antiknock index)

octane rating usually displayed on U.S. gaso-

line pumps is calculated as research octane number plus motor octane number, divided by

2, that is:

RON+MON

The CLC or AKI octane rating is usually 4 points lower than the RON rating:

96 RON equals 92 GLC 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 collision.

Do not use any unleaded fuel with octane

ratings lower than 96 RON or 92 CLC or AKI.

Page 62

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 ve-

hicle driveability and performance problems

and may damage critical parts of your vehic-

le'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 "Gas-

ohol". You may decide to 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 vehicle:

• Deterioration of driveability and performance.

• Substantially reduced fuel economy.

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

• 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.

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 long-life guarantee.

The Porsche paint finish is of a high quality baked synthetic enamel. The color and enamel type designation are indicated on a plate attached to the left front doorjamb. When buying touch-up paint, always give the paint and the car's identification numbers to your dealer.

A well-cared for Porsche can look like new 10 years later. It all depends on the amount of care the owner is willing to give the car.

Your Porsche dealer has a number of car-care

products and can advise you which ones to

use for cleaning the interior and exterior of

your car. Whether you use Porsche recom-

mended products or other commercially avail-

able cleaning agents, first make sure of their

correct application.

• 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. 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 sun-

light. 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 vehicle, and some tracks may cause damage to the un-

derbody.

Use plenty of water, a car-wash and wax solution and a soft sponge or hose brush. Begin by spraying water over the dry surface to remove all loose dirt before applying the carwash and wax solution. Use plenty of water to rinse the vehicle off. Wipe everything dry with a chamois to avoid water spots.

Page 64

To guard against corrosion from inside out,

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

wipe dry thoroughly. Also inspect all weather-

strips 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, debris and

road salt from the underside with a powerful jet of water. Be sure to include the wheel hous-

ings, bumpers, muffler, tailpipe and brackets. This should be done twice a year and is best accomplished after the vehicle has been driven through a heavy rain. Let engine and exhaust 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 off.

Exterior

Care of the finish

Oils contained in the paint are the most important 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 approved cleaning

agents and preservatives. The use of polishes

is recommended only after it becomes evident that the normal preservatives no longer ac-

complish the job.

Dull finishes and plastics

Plastic parts, such as light bulb lenses, deco-

rative stripes, panels, etc., will come clean dur-

ing 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 chem-

ical 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 touch-up job will not suffice. The affected surface must be smoothed with sand paper and covered with an anti-

rust 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 sub-

stitute 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 solution.

Do not allow tree sap or bird droppings to har-

den on the paint.

Page 65

Windows

Keep silicone sprays 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 an alcohol base commercial window cleaning agent for the inside and outside. If a chamois is used for polishing the glass, it should exclusively be used for that

purpose. To assure that windshield washers also func-

tion at freezing temperatures, anti-freeze must be added to the washer fluid reservoirs beforehand. 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 da-

mage 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 aggressive

agents or dry methods. If very dirty, it can

be cleaned with benzine. Make certain that the plastic coating is not damaged in

cleaning by hard objects 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!

The foil base must be used to apply gummed stickers (3 such foils have been included with the vehicle).

In so doing, following the instructions below:

1. Clean the windshield in the area for application.

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

3. Pull off the protective film.

4. Spray the gummed side of the support 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 support base to the windshield and spray it once again.

6. Any liquid and bubbles under the support base must be brushed out using a flexible plastic scraper.

7. Dry the windshield on the base using a soft cloth.

8. Put on the gummed sticker.

When removing the gummed sticker or the support base, the support base must first be sprayed.

Wiper blades

Always loosen frozen wiper blades from glass as they may tear otherwise.

Remove all wiper blades periodically and clean 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 and doors 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 cast, some special care is necessary. Aside from road dirt and salt sprays, brake metal dust will exert corrosive effects.

If left on too long, brake metal dust can cause pitting. Wash the wheels with a sponge or hose brush every other week. Road salts should be removed weekly with an acid free cleaning solution. 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.

Remember that moisture and road salt on brakes may affect braking efficiency. Test the brakes after each car or wheel wash.

Page 66

Interior

Glass

Use the same cleaning agents as for exterior and polish dry.

Fabric

Use a vacuum cleaner or a soft bristle brush

to remove dust and loose dirt from carpeting,

upholstery, headliner and other trim. Dirt stains can usually be removed with a lukewarm soap water or all purpose cleaner solution, or a dry foam cleaner. For greasy, oily and other stub-

born 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

retract 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 purpose 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 leather preservative "Karneol" - Porsche part-No. 000.043.007.00 (except for special leathers such as, for example "PerlweiB - pearl white") to all dry surfaces with a clean and soft woolen cloth. Let your Porsche dealer advise you on the use of the leather preservation product.

Corrosion protection

The engine compartment, as well as all engine,

transmission, front and rear axle assembly surfaces at the factory have been treated with wax based coating for protection against corrosion.

WARNING Do not apply additional undercoating or

rustproofing on or near the exhaust mani-

fold, exhaust pipes, catalytic converter or

heat shields. During driving, 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 pro-

tective coating to all engine compartment pa-

nels, flanges, cavities, seams and engine assembly surfaces.

Page 67

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 manufacturer.

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, trans-

mission or engine assemblies are repaired, the lost anti-corrosion coating of the af-

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

• 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 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 getting 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 con-

nected with the ignition system; there-

fore, 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 purpose.

• When working underneath the car with-

out 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 69

Tool kit

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° (arrows).

The tool kit contains tools needed for minor road side repairs or adjustments.

Regulations in some countries require addi-

tional tools. Details should be obtained before

leaving for a foreign country.

Car jack

The car jack is located underneath the luggage

compartment, together with the collapsible spare tire. The tire is covered by a lid with a quick release catch.

WARNING

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

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

the jack is accidently dislodged, you could be seriously injured. When working under the vehicle, always use safety stands specifically designed for this

purpose.

Page 70

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 con-

ditions as well as the amount of dilution 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 engine

is new.

• The engine in your vehicle depends on

oil to lubricate and cool all of its moving 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.

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 clean with a rag.

2. Reinsert dipstick; push it in all the way 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 recommendation is given under "Engine Oils".

1. Remove oil filler cap (arrow).

2. Top up with quality oil labeled "API Service

SF or SE".

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

4. Replace cap and tighten.

WARNING The oil filler cap must be secure to avoid

oil spill causing fire hazard.

Page 71

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 multi-grade 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". 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 running down your arm. Wear eye protection.

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

Be mindful of how you dispose of used engine oil. 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 War-

ranty & Maintenance booklet accompanying the vehicle apply to normal operating conditions and must be adhered to, including inter-

vals 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.

1. Loosen and remove oil filler cap.

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 handtighten

according to filter manufacturer's instruc-

tions 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 about 7.9 U.S. qts.

or 7.5 liters of engine oil labeled "API Service SF or SE" (see "Filling Capacities").

Do not overfill.

8. Check the oil level with dipstick. Top up

if necessary. Reinstall oil filler cap and

tighten securely.

9. Run engine at various speeds for 3 - 5

minutes and check for leaks.

See "Cautions".

Page 72

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 transmission oil changed at your Porsche dealer, who has the required lubricants and the necessary 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 da-

maged 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 MlN 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". The hypoid oil in the final drive does not have to be changed.

Page 73

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.

Since the closed cooling system loses almost no coolant, topping up is normally not required. An obvious loss of coolant indicates leakage. In this case contact your dealer.

Cooling system

For year round driving, anti-freeze is added at the factory for temperatures down to:

-23°F/-30°Cfor(J.S.

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

freeze should also remain in the cooling system for summer operation. Cooling system capac-

ity 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 spe-

cified by Porsche for aluminium engines and radiators may cause corrosion of the cooling system, leading to engine overheating and damage.

WARNING

The air conditioner condensor fan is elec-

trically driven. It is switched on automati-

cally by a thermostat when the coolant reaches 92° C/198" F. Even when the engine is turned off, the fan will continue running, until the coolant temperature has dropped to 87° C/189° F and until the engine itself has cooled down sufficiently.

Checking coolant level in expansion tank

A correctly functioning cooling system requires 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 compartment (see illustation). Since the expansion tank is transparent, it is not necessary

to unscrew the filler cap. When the engine is cold, the coolant level

should reach the filler mark on the expansion

tank. When the engine is warm, the coolant

level will be above the filler mark.

WARNING

• Do not open the filler cap when the engine 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 carefully 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 filler mark. Too much added coolant will escape through the pressure cap when coolant warms up.

For more details see "Coolant temperature

gauge and coolant temperature warning light".

Page 74

Winter operation

At the beginning of the winter season, have the coolant checked for anti-freeze concentration.

The ratio between water and anti-freeze de-

pends 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.

Bleeding cooling system

If more than about 1.1 U.S.qt.or 1 Liter must be

added, the cooling system should be bled.

1. Move the temperature control lever (upper lever) in the center console all the way to the right.

2. Start the engine and allow it to run at increased idle for about one minute.

3. Turn the engine off.

4. Recheck the coolant level and add as necessary.

Changing coolant

1. Set the temperature switch at 30° C with the engine cooled off, and switch on in

the ignition.

2. Remove filler cap from expansion tank.

3. Unscrew and remove drain plug (arrow) from radiator and drain coolant.

4. Unscrew and remove drain plugs (arrow)

from left and right hand sides of crankcase and drain coolant.

5. Replace seals for drain plugs on crankcase and the O-ring for drain plug on radiator.

Tightening torques:

radiator plug:

1.1-1.5 lb ft or 1.5-2.0Nm crankcase drain plugs:

33 - 37 Ibft or 45 - 50 Nm

6. Add coolant until level reaches edge of filler

cap opening (with heater level set at "warm").

7. Run engine at increased idle until it reaches

operating temperature and recheck coolant level.

8. coolant level should be in the middle of ex-

pansion tank above the filler mark.

Page 75

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) systems also function at freezing temperatures, antifreeze/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.

Intensive windshield washer system reservoir (where applicable)

The reservoir is located in the engine compartment in front of the radiator.

To avoid paint damage, we recommend the exclusive use of a "special silicone remover" cleaning agent. Any other solution can da-

mage the car paint.

Your Porsche dealer can advise you which product to use.

Also refer to "Filling capacities" and ing system mixing ratios".

Page 76

Brake fluid reservoir

The brake fluid reservoir is located in the engine compartment.

The brake fluid reservoir has three chambers: 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 between the MIN

and MAX marks.

To add brake fluid, unscrew the cap. The vent

bore in the cap should be kept clean.

If the brake fluid level should drop below the MIN mark, the central warning light and the brake fluid warning light will flash (see "Cen-

tral warning light system").

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 reser-

voir, use only new and unused DOT 3 or DOT 4 brake fluid that meets SAE specification J1703 and conforms to Motor Vehicle Safety Standard 116.

• Do not use any other brake fluid or brake

fluids that have absorbed moisture 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.

Page 77

Power steering fluid reservoir

The reservoir is located in the engine compartment 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 Maintenance Sche- dule. 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 element.

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, cleaning

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

Page 78

Tires/Wheels

Tire pressures

Tire life

The original equipment tires on your Porsche comply with all applicable Federal Motor Ve-

hicle 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 conform 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 factory installations.

WARNING Incorrect tire pressures cause increased

tire wear and adversely affect road holding

of the vehicle, leading to loss of control.

Always use an accurate tire pressure gauge when checking inflation pressures. Do not exceed the maximum tire inflation pressure listed on the tire sidewall. (Also refer to "Technical data"). Cold tire inflation 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 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 2 000 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 torque 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 (1.6 mm).

Page 79

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 properly and are even less effective on wet roads.

WARNING Do not drive with worn tires or tires show-

ing 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.

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 ther-

mal or mechanical overloading due to a loss of

pressure or any other prior damage, we re-

commend that the tire be replaced for safety

reasons.

If one faulty tire is replaced it should be noted that the difference in tread depth on one axle

must not exceed 30 %.

Perform visual inspection.

Parking at the curb

Hard impacts against curbs (or traffic islands)

are dangerous and may cause hidden tire da-

mage which is not noticeable until later. (Danger

of accidents at high speeds). Tires have a

memory!

WARNING:

If 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.

Before mounting new tires, check with your Porsche dealer about the current release status.

For tires with VR quality standard, there are currently no final standards concerning tire strength at speeds above 210 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 balancing light alloy wheels, use only adhesive balancing weights supplied through the Porsche parts service.

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.

Page 80

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 before. When remounting, put tires with the most tread depth at the front. Have tires/wheels balanced as soon as possible.

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 required for the regular radial ply tires. However, do not exceed the maximum tire inflation pressure listed on the tire sidewall.

Snow tires should have the same load capacity 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.

WARNING Tires with badly worn treads and studs are

very dangerous. Make sure they are re-

placed 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.

Snow chains Should snow chains be necessary, they

must be mounted on the drive wheels only.

Check with local authorities for possible restrictions.

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.

New tire identifications

The European tire manufacturers have changed their tire identification system for SR and HR-tires pertaining to maximum permissible speed and maximum load carrying capacity for belted tires. The following is an example only.

185 / 70 R 15 88 Q M+S

During the transition period some tires might show both old and new identification codes, such as: 185/70 SR 15 88 Q M+S. In this instance, the new codes apply.

The identification codes for VR tires remain unchanged; for example: 225/50 VR16.(V=

maximum permissible speed for radial tires, i.e. over 130 mph or 210 km/h).

Page 81

Collapsible spare tire

The spare tire is stored underneath the luggage compartment cover. It is covered by a

lid with a quick release catch. The car jack is stored behind the spare tire. Stored inside the wheel rim is the electric air compressor kit. This kit also includes a plastic cover for the road wheel to keep luggage compartment 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. The spare wheel may only be fitted at the front. This means that when one of the rear wheels is defective, the intact front wheel on the same side of the car must be fitted at the rear. This improves handling of the car and reduces wear on the tires. This applies for cars equipped with locking differential, in particular. Only one collapsible spare tire may be fitted to the car. Remount the original road tire as soon as possible.

Inflating the collapsible 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 32 psi or

2.2 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 collaps-

ible tire in the luggage compartment.

The collapsible spare tire cannot be repaired or mounted with standard workshop equipment. Repair and remounting must only be done by the manufacturer.

Tire tread depth

As required by law, the tread depth of the

collapsible 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 mat-

ter 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.

Page 82

Lockable wheel nuts

You can guard against wheel theft by installing

lockable wheel nuts on your wheels. Each kit contains four keys, four wheel nuts with lock

sleeve and a standard wheel nut for the spare wheel. 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, remember to leave one key with the service attendant.

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.

To unlock a wheel

1. Remove protective plastic cap from wheel nut.

2. Insert key all the way and turn left or right

about 90°.

3. Remove lock sleeve together with inserted key.

4. Replace protective plastic cap.

Generally, it is not necessary to balance the wheels after installing lockable wheel nuts.

To lock a wheel

1. Remove protective plastic cap from wheel nut.

2. Insert key all the way and slide lock sleeve over wheel nut.

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

4. Press lock sleeve firmly against wheel nut while removing key.

5. Replace protective plastic cap.

WARNING

• 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 vehicle when it is jacked up.

Jacking at any other place may damage the vehicle or may result in personal injuries.

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

• 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 changing 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.

Sequence of operation

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

2. Securely insert the car jack in the front jackport 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. Put the collapsible tire on on the front. (Then, if a rear tire is flat, raise the vehicle at the

back and replace the flat back tire with the front tire.)

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

will center the wheel correctly.

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

sure gauge.

7. To lower the car, turn the jack handle coun-

terclockwise till tire touches ground.

8. Fully lower the vehicle and remove jack.

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

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.

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

• The car jack must never be used as a support to work underneath the vehicle. If the jack is accidentally dislodged, you 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 personal 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 serious damage.

Lifting with workshop hoist

Make sure there is sufficient clearance between pads and vehicle before driving vehicle onto hoist, especially if the vehicle has a large front panel or spoiler. The vehicle must

be lifted only at the lift points illustrated. The front lift points for the car jack also apply

when using a hoist. The rear lift points are located on the rear axle

control arm mount.

Take care to avoid damaging critical components which are close to the lift points.

WARNING

When removing components such as engine block, transmission housing, fuel tank, wheels, front or rear axle, anchor vehicle 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.

Lifting with floor jack

The same lift points as illustrated for the hoist

also apply when using a floor jack. To avoid

damage to the underbody or chassis frame,

it is necessary to insert a rubber pad between

the floor jack and the lift points.

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 are shown in a list on the floor board.

Before replacing a fuse, turn off all electrical 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 putting it on relay VIII. 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 have been relay boards attached for various electrical operations. Testing and replacement of a defective relay should be done only 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.

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 system, 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.

Disconnecting the battery while the engine 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.

WARNING

• Do not lay tools or other metal objects on the battery as they could cause a short circuit across the battery terminals.

• 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 surfaces.

• 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 baking soda to neutralize the acid and prevent 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 up 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 top 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. Corrosion

can be prevented by coating terminals 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. Additionally, more power is consumed while starting, and the headlights, heater, rear window defogger, etc., are used more frequently. Curtail unnecessary power consumption, particularly 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 starting problems but will also live longer.

Page 87

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 driven 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 POSITIVE (+) 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 disconnect charger cables. When the electrolyte fluid has stopped "bubbling" in the cells, close the vent caps.

• Tighten the vent caps and reinstall battery.

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. Preferably lay a cloth over open vents to reduce explosion hazard.

How to use jumper cables

WARNING

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

and instructions of the jumper cable manufacturer.

• The jumper cables must be long enough so that neither vehicles nor cables touch another.

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

Always connect POSITIVE (+) to POSITIVE

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

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

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

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

4. Connect clamp on opposite end of cable to a bare metal part of car with discharged

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 cables 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 towing. Damage to the catalytic converter, the transmission, and/or other components of the car may result.

Emission Control System

WARNING

Starting

In the Interest of Clean Air

Pollution of our environment has become a problem that is of increasing concern to all of us. We urge you to join us in our efforts for cleaner air in controlling the pollutants emitted from the automobile.

Porsche has developed an emission control system that controls or reduces those parts of the emission that can be harmful to our environment. Your Porsche is equipped with such a system.

Porsche warrants the Emission Control System in your new car under the terms and conditions set forth in the Warranty & Maintenance booklet.

You, as the owner of the vehicle, have the responsibility to provide regular maintenance service for the vehicle and to keep a record of all maintenance work performed. To facilitate

record keeping, have the service performed

by authorized Porsche dealers. They have

Porsche trained mechanics and special tools to provide fast, efficient service.

To assure efficient operation of the Emission Control System:

• Have your vehicle maintained properly and in accordance with the recommendations described in your Warranty &

Maintenance booklet. Lack of proper

maintenance, as well as improper use of the vehicle, will impair the function of the emission control system and could

lead to damage.

• Do not alter or remove any component of the emission control system unless

approved by the manufacturer.

• Do not alter or remove any device, such as heat shields, switches, ignition wires, valves, etc., which are designed to protect your vehicle's emission control system.

• Do not continue to operate your vehicle if you detect engine misfire or other unusual operating conditions.

• Do not leave vehicle engine idling unattended after starting. If warning lights should come on to indicate improper operation, they would go unheeded. Extended idling also produces heat, which could result in overheating or other damage to the vehicle or other property.

Parking

• As with any vehicle, do not park or operate your vehicle in areas where combustible materials, such as dry grass or leaves, can come into contact with a hot exhaust system.

Undercoating

• Do not apply additional undercoating or rustproofing on or near the exhaust

manifold, exhaust pipes, catalytic converter or heat shields. During driving the substance used for undercoating could overheat and cause a fire.

Page 96

How Emission Control Works

When an automobile engine is running, it uses energy generated through the combustion of a mixture of air and fuel. Depending on whether a car is driven fast or slowly or whether the engine is cold or hot, some of the fuel (hydrocarbons) may not be burned completely but be discharged into the engine crankcase or exhaust system. Additional hydrocarbons may enter the atmosphere through evaporation of fuel from the fuel tank. These hydrocarbons

(HC), when released into the air, contribute to

undesirable pollution.

In addition, carbon monoxide (CO) and oxides

of nitrogen (NOx) contribute to engine emis-

sions. They, too, are formed during the combustion process and discharged into the ex-

haust system. To reduce these pollutants, your Porsche is

equipped with a precisely calibrated fuel in-

jection system to assure a finely balanced

air/fuel mixture under all operating conditions.

Oxygen Sensor

The oxygen sensor, installed in the exhaust pipe continuously senses the oxygen content of the exhaust and signals the information to an electronic control unit. The control unit corrects the air/fuel ratio, so that the engine al-

ways receives an accurately metered air fuel

mixture.

Crankcase Ventilation

Through Crankcase Ventilation undesirable emissions from the engine crankcase are not

permitted to reach the outside atmosphere.

These emissions are recirculated from the

crankcase to the air intake system. From here

the emissions mix with the intake air and are

later burned in the engine.

Catalytic converter

The catalytic converter is an efficient "clean-

up" device built into the exhaust system of the

vehicle. The catalytic converter burns the un-

desirable pollutants in the exhaust gas before it is released into the atmosphere.

The exclusive use of unleaded fuel is critically important for the life of the catalytic converter. Therefore, only unleaded gaso-

line without additives must be used.

The catalytic converter will be damaged by

• push or tow starting your vehicle

• misfiring of the engine

• turning off the ignition while the vehicle is moving or

• by other unusual operating conditions.

Do not continue to operate your vehicle under these conditions, as otherwise fuel can reach the catalytic converter. This

could result in overheating of the converter.

The Emission Control System and its other

related components are illustrated and de-

scribed on the following pages.

Fuel Evaporation Control

Fuel Tank Venting

The expansion chamber and the safety valve

prevent fuel from escaping to the outside at

extreme high outside temperatures and when the car is driven or parked at an incline or in

any other nonlevel position. The safety valve

works as a restrictor in the tank vent line between the expansion chamber and the carbon canister.

Vapor Control System and Storage

When the fuel tank is filled, vapors are collected in the expansion chamber and filler tube by a vent line leading the vapors to the activated carbon canister where they are stored as long as the engine does not run. During running of the engine, the vapors are stored in the activated carbon canister as long as the temperature controlled ON/OFF valve is in the OFF-position.

The temperature controlled ON/OFF valve stops purging of the canister during all other running conditions of the engine if the coolant temperature of the engine is below a defined temperature.

Purge System

Fuel vapors from the carbon canister will be mixed with fresh air taken from the engine compartment. This mixture will be directed via two vacuum controlled valves to the air intake system housing.

The temperature controlled ON/OFF valve has the following functions:

To stop purging of the canister during idle (the

rich vapor flow from the canister would in-

fluence the mixture characteristic). To allow purging of the canister during all other

running conditions of the engine.

The vacuum controlled ON/OFF valve has the function to control the purge flow (high intake vacuum means low purge flow and low intake

vacuum means high purge flow).
