Location of Identification Plate,
Chassis Number, Engine Number
and Paint Number

When ordering spare parts or submitting
inquiries, always quote chassis and engine
numbers to ensure correct and prompt ser­vice.

6

Data bank

The data bank is fixed on the floor in the rear of
the luggage compartment next to the spare
wheel well.

Identification plate

The identification plate is riveted on the
front cross member, behind the bonnet lock.

Chassis number

Engine number

Paint number

The chassis number is stamped on the top of
the right wheel arch in the engine compart­ment and is visible through a cut-out in the
wing flansch.

The engine number is stamped on the front
reinforcing rib in the top half of the crank­case.

The paint number plate is fixed on the left
hand door lock pillar.

For your own safety, you should,
before a journey,

Keys

check pressures and condition
of the tyres

clean the windows and light lenses,
front and rear

turn the ignition on, and check that
headlamps and turn indicators
are functioning

take note of the central warning
light

adjust rear view mirrors to give
uninterrupted rear vision

fasten seat belts, so should
the passengers.

Have the oil level in the automatic
transmission checked regularly,
even in-between the recommended
maintenance intervals.

8

With the vehicle you receive two master and
two auxiliary keys. The two master keys fit all
locks, the auxiliary keys do not fit the glove
compartment lock.

Vehicles with a rear seat storage compart­ment receive two additional keys for the
compartment lock.

One master key has a built-in flash light. The
light is on as long as the contact button is de­pressed.

When the light begins to fade, the battery
must be replaced with one of the same type.
A discharged battery could leak and dam­age your clothing.

By virtue of the new format for the master
and auxiliary keys, the unauthorised manu­facture of keys is almost completely elimi-

nated. This means however, that you your­self will not be able to get replacement keys
cut, you must order them from the manufac­turer.

a Master key
b Auxiliary key
c Rear seat storage compartment key

Should you need new keys, you must give
the key number. This number is noted on
the plastic tab, that you receive with the
keys. Keep this tab somewhere safe, not in
the vehicle.

Alarm system

If your car is equipped with an alarm system
you will have received two S-keys instead of
the normal master keys. The alarm system
can be activated only with the S-key by lock­ing the doors or closing the luggage com­partment door and turning the key to the
left. If the doors are locked with the auxiliary
key then the door will be mechanically lock­ed but there is no contact to activate the

alarm. The alarm system is switched off au­tomatically when a door or the luggage com­partment is opened with the S-key. If the lug­gage compartment door is opened while the
alarm system is switched on, the key must
be turned to the left to reactivate the alarm
system. If the drivers or passenger side door,
engine compartment hood or the luggage
compartment door is opened while the

alarm is activated a specially protected siren
will sound for about 30 seconds. The engine
cannot be started.
In the interest of safety the S-Key should ne­ver be lent out to other persons. For this rea­son the fuel filter cap can only be locked
with the auxiliary key. This key can be used
as a"workshop key" and can also be handed
over at filling and service stations.

9

Doors

The doors are opened from the outside by

pulling the inset door handle, and from

inside, by pulling lever (C).
Access to the storage compartments in the
door is obtained by pressing the safety

knob, and tipping the armrest outwards.

The window regulators are operated by the

rocker switches in the middle console.

10

Warning: To avoid injury to unknowing occu-

pants of the vehicle, (e. g. children) by the
closing of the windows, the ignition key
should always be withdrawn when leaving
the vehicle, if only for a short period.

The footwell lights (D) mounted forward in
the lower part of the door trimcone on, with
the switch in the appropriate position, when
the door or the luggage compartment door

is opened. Each light can also be switched
on or off individually by means of the inte­grated switch.

Central door locking

By means of the central door locking system
both doors are electrically locked or unlock­ed by operating one lock.

When the doors are locked the locking but­tons (A) must be fully retracted. If this is not
the case the lock on that door is not properly
engaged. Re-open the door, close it pro­perly and re-lock it.

On vehicles with central locking the passen­ger door can be locked and unlocked by
turning the knob (B) as well as with the key.

To prevent being accidentally locked out of
the vehicle it is impossible to lock the door,
while open, either using the knob (B) or with
the key.

Central locking is only possible when both
driver and passenger doors are closed. If

one door is locked before the other is closed
it will automatically unlock when the other
door is closed.

A mechanical locking or unlocking of the

individual doors is only possible when the

ignition is switched on or when the ignition
key is turned to pos. 1. This cut out of the
electrical function prevents the doors from

locking in the case of a short circuit or if
deformed in an accident.

When the ignition is switched off but with the
key still in the ignition lock the doors can be
centrally locked using either the key or the
knob (B).

Door guard lights

The door guard lights come on when a door
or the luggage compartment door is open­ed.

11

Interior lights

The interior lights, which are independent
from one another, come on, with the switch
in the appropriate position, as soon as a
door or the luggage compartment door is
opened. The interior lights mounted in the
roof lining can be switched as following by
tipping the light cover:
a - light switched on permanently

b - light switched off permanently

c - light comes on only when a door or lug-

gage compartment door is opened.

12

The footwell lights mounted forward in the
lower part of the door trim have following
switch positions:

a - light comes on only when a door or lug-

gage compartment door is opened
b - light switched off permanently
c - light switched on permanently.

The luggage compartment light in the rear
lid has the following switch positions:

a - light comes on only when a door or lug-

gage compartment door is opened
b - light switched off permanently
c - light switched on permanently.

Front seats

Correct seat positioning is imperative for
safe and tireless driving. To enable individual
seating comfort, the seats are adjustable for
and aft and the backrest angle is adjustable.
To find the most suitable seat position, we
suggest the following procedure:

1 Pull the locking lever at the front of the

seat upwards, and slide the seat until your
leg is straight when fully depressing the
clutch pedal. You should not however
have to outstretch your foot to reach this
position. Let the locking lever down, and
ensure that the seat is locked in a ratchet
on the seat slides. Never try to adjust the
seat whilst driving, as a sudden change of
seat position could cause you to lose
control of the vehicle.

2 Grip the top half of the steering wheel.

Then set the backrest angle so that with
fully outstretched arms, your shoulders
still contact the backrest.

Then check the steering wheel position, and
view of the instruments.

For optimum legroom and view of the instru-

ments, the steering wheel and instrument
console can be released, adjusted, and then
re-locked.

The backrests are secured in position to
stop them tipping forward during braking; to
release, press the button on the side of the
backrest.

Similarly, the rear seat backrests can be re­leased, and tipped forward, thereby giving

more luggage room in the rear.

13

a - For and Aft adjustment
b - Height adjustment
c - Backrest adjustment

Electric seat adjustment Hand operation

In vehicles fitted with electrical seat adjust­ment, the controls for the electric motors
which adjust the seat for/aft, height, and
rake angle can be found mounted in the out­side flanks of the seats.

14

To prevent damage to the belt lock and to
the seat cover, care should be taken that the
belt lock is pushed outwards so that it can­not jam between the seat and seat backrest

when the seat is moved forward.

Manual operation of the seat is also possible
in case of possible electrical malfunction. To
do this pull the locking lever at the front of
the seat upwards and slide the seat to
achieve the desired seating position, then
release the lever.

Rear view mirrors

Before beginning a journey you should en­sure that the rear view mirrors are properly
adjusted.

The interior rear view mirror is stuck directly
on the windscreen. This enables a very short
mirror stem to be used thereby obviating
vibration, and a blurred image.

The mirror is adjusted to the anti-dazzle
position by pressing the lever underneath it.

The electrically adjustable wing mirrors can
be set with the switch in the driver's door.
The passenger door wing mirror is adjust­able by the same switch, by pressing the
rocker switch beside the adjuster switch into
the appropriate position.

When necessary, the wing mirrors can also
be adjusted by hand.

The wing mirrors are also electrically heated
when the rear window heating is turned on.

15

Safety belts

Your Porsche is equipped with safety belts
as standard fittings. All occupants of the car
should wear safety belts for their own safety,
on every journey. To remind you of this, a
warning light in the middle console comes
on for approx. 6 seconds, every time the
ignition is turned on.

The lap and shoulder belts as fitted are not
suitable for children under 140 cm (4 ft. 6
ins.) tall. To stop them distracting the driver's
attention, and for their own safety, children
under 12 years old should always travel in
the rear seats.

Never use one seat belt for two people.

Loose clothing affects the fit of the seat belt.
You should therefore take your coat off, be­cause a correct seating position and free­dom of movement are important for comfort
and safety.

Do not run the belt over fragile objects in

your pockets, e. g. spectacles, pens or a

pipe etc. as these could represent additi­onal hazards.

Please remember when driving abroad, that
in some countries the wearing of seat belts
is compulsory.

Putting on the belts

Decide the best seating position for your­self. Take hold of the sliding buckle and pull
the belt firmly over chest and hips. Press the
buckle into the respective anchor point until
you hear that the latch is locked. Slide the
plastic loop up to the buckle.

Avoid twists in the webbing when putting
on the belt.

16

The lap part of the belt must always stay taut
over the pelvis. After putting the belt on, you
should therefore pull the shoulder part of the
belt upwards as shown in the picture. Now
and again during the journey, you should
repeat this procedure to ensure that the lap
belt is always taut.

The locking mechanism in the roll-up unit is
so designed, that by rapid acceleration or
braking, cornering or driving on steep in-

clines, the belt is locked. This locking system
reacts more quickly to the retardation of the
car than to any pull on the belt.

Releasing the belts

To release the belt, press the red button
marked "press". The buckle then springs out
of the anchorage, whether there is any load­ing on the belt or not.

Make sure that the belts are always fully re­tracted when not in use. This will prevent
them becoming dirty and avoid unneces­sary damage to the belts themselves.
You should check your seat belts regularly
for signs of damage to the webbing. Make
sure that the locks and anchorage points are

in good condition. If the belts have been
subjected to high loads or stretched in an
accident, have them replaced in the inte­rests of your own safety.

Back seat safety belts

The back seats are equipped with automa­tic lap belts. Do not twist the belt when put­ting it on. The belt is released by pressing
the red button.

Warning. Please do not make any alterations
or additions.

Footbrake

Clutch

Handbrake

The handbrake is cable operated to the rear
wheels only. It is applied by pulling the lever
upwards.

To release the brake, the lever must be pull­ed upwards whilst pressing the button in the
end of the lever until the ratchet is cleared,
and then letting the lever downwards.

The central warning light and the handbrake
warning light will go out when the brake lever
is fully released. (See Automatic warning
unit.)

18

To reduce the pedal effort necessary when
braking, your Porsche has a brake servo unit.
The vacuum necessary to operate this unit is
taken from the engine inlet manifold, when
the engine is running.

Please note that with a defective servo unit,
or when the vehicle is being towed with the
engine turned off, the braking effort required
is considerably increased as soon as the
vacuum reservoir is used up.

With properly bled and functioning brakes,
the free movement at the brake pedal will
remain constant. This free travel before the
brakes start to operate can be 20 mm (0.8
ins.).
Should this free travel suddenly become
bigger, either air has entered the system, or
one of the brake circuits has malfunctioned.

A malfunction of one of the brake circuits or
the loss of brake fluid would cause the cen­tral warning light to blink. (See Central warn­ing unit.)

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

Should this free travel suddenly become
bigger, it could mean a malfunction of the
clutch. Please consult your workshop for
rectification.

1 -Steering unlocked, and all electrical cir-

cuits are operational except direction in­dicator - reversing lights, wing mirror ad-

justment, rear screen heating and fresh

air fan.

2 -Ignition is switched on. All circuits can

now be operated. With the motor
stationary, the central warning light and

the individual lights are on for control

purposes.

Steering lock and ignition switch

The ignition key has 4 positions:

0 -The steering is locked. All circuits con-

nected to the ignition switch are off.
This is the only position in which the igni­tion key can be withdrawn, and the
steering lock only operates after the key
is withdrawn.
The parking lights can be operated with
the switch in this position by using the
direction indicator lever.

20

3 - By turning the key to the right, the starter

motor is operated. As soon as the engine
fires, release the key. It will spring back

to position 2. With the engine running,
the central warning light and the other
warning lights should go out except the

brake warning light, which will go out
after the first application of the brakes
(see central warning unit). During the
operation of the starter motor, the items
with heavy electrical consumption, e. g.
headlights, rear screen heating, wipers/
washers, will be interrupted.

The starter motor should not be operated for
longer than 10-15 seconds. If the engine
does not fire, repeat the starting procedure
after a pause of approx. 10 seconds. Every
time the starter motor is operated, the key
must be returned to position 1 before trying
again, as a device is built into the ignition
switch to prevent inadvertent operation of
the starter motor whilst the engine is run­ning.

Starting the engine

neutral, but drive off immediately while
avoiding high rpm and full throttle until the
engine has reached its normal operating
temperature.

Warning: Never turn the key back to posi-

tion 1 whilst the vehicle is moving.

It is in your own interest to always remove

the ignition key when leaving the vehicle, if
only for a short period, and to ensure that
the steering lock is fully engaged. This is
done by rocking the steering wheel left and

right. This might also be necessary to re-

lease the lock when turning on the ignition.

When the engine is cold, component parts
being controlled in dependence of the tem­perature automatically provide the correct
fuel-air mixture required for starting.

Therefore, special starting instructions are
not necessary.

With a hot engine we recommend that
you fully operate the accelerator when start­ing. Do not allow the engine to warm up in

By cold weather, it is recommendable to
depress the clutch pedal when starting the
engine, even when the vehicle is in neutral.

Never start the engine or let it run in con­fined spaces. The exhaust contains the co­lourless and odourless gas, carbon mono­xide, which is poisonous, even in small
quantities.

Please take note of the hints on running-in.

21

Fog lights
Rear fog lights

(on vehicles without rear fog light: .
button for re-setting trip meter)

The fog lights and the rear fog light can be
switched on in addition to the headlights by
pressing the respective switch. The lamp built
into the switch comes on when fog lights are
switched on. (The rear fog light operates only
when the front fog lights are switched on.)

Note: Take account of the varying laws in dif­ferent lands controlling the use of fog lights.

22

Light switch

Switch in position 1: Sidelights
Switch in position 2: Headlights

In both of the switch positions the following
are also on: Backlights, Number plate lights
and instrument illumination. With the ignition

tion turned on, and the switch in position 2, the

headlights are elevated.

Instrument illumination

When the headlights are switched on the in-

strument illumination and Automatic gear se­lector illumination (vehicles fitted with auto­matic transmission) comes on automatically.

The illumination intensity of the instruments
is controlled by turning the knurled wheel
under the instrument panel.

Revolution counter

Speedometer

The transistorised revolution counter indi­cates the number of thousands of revolu­tions per minute of the engine.

The red range on the scale of the instrument
is a visible warning of the maximum permitt­ed revolutions per minute. Should you inad­vertantly, during acceleration, exceed these
revolutions, a built in governor in the distri­butor cuts out the ignition current.

The electronic speedometer shows the
speed in miles and kilometres per hour.

The upper odometer registers the total mile­age driven. The trip odometer can be set
back to zero when the ignition is on, by press­ing the button under or in the left hand side
of the instrument console.

23

Main beam warning light

Red Range-Warning

The main beam warning light in the instru­ment console lights when the headlamps
are on main beam. It goes out when dipped
beam is selected.

Blinker warning light

The blinker warning light flashes at the same
frequency as the blinker lights. Should one
of the blinker lights fail, the flashing is noti­ceably quicker.

Central warning light

The central warning light in the instrument
console lights when a fault occurs in one of
the systems in the vehicle. See "Automatic
warning unit".

Cooling fluid
Temperature Gauge

White Range - engine cold

Avoid over-revving the engine or labouring

Middle Range - normal

The temperature gauge needle should nor­mally stay in this range. It is not unusual, when
the engine is being highly stressed, that the
needle tends towards the red range, but it
should return to the middle when the engine
loading is reduced.

If the needle goes into the red range it means
that the engine is being overloaded (by high
outside temperatures) and the warning light
will come on.

Warning light

If the warning light comes on, check that the

cooling fan is working. If the fan is not rotating,
the V-belt may be slack or broken; if so, it must
either be tightened or renewed. In cars with
air-conditioning, the electric fan located in front
of the air-conditioning condenser must also
operate. If it does not, there is a fault in the po­wer supply or the temperature switch.

Allow the engine to cool down and drive to the

nearest authorized workshop, keeping a con-

stant check on the temperature gauge.

Avoid idling, crawling and engine speeds over
4000 rpm.

Consult the chapter on the cooling system.

24

Warning Lights

(see also Central Warning Unit)

TAIL LAMP

The warning light comes on when a tail light
ceases to function.

Consult the chapter on the cooling system.

PARKING LIGHTS

This light comes on in the Combi-lnstrument
when the sidelights are turned on and goes
out again when the headlights are turned on.

Fuel Gauge

With the ignition turned on the gauge shows
the amount of fuel in the tank. If the level is too
low the fuel warning light comes on.

Warning light

The warning light comes on when about 8 liters

(7 Imp. qts) are left in the tank. The tank should
be filled at the next opportunity.

STOP LAMP

The warning light comes on when the ignition
is switched on and must go out after the first
brake application. If a brake light bulb is defec-

tive the warning light will not go out.

WASH FLUID

The warning light comes on before the screen-

wash water runs out, indicating that about 2
liters (1.75 Imp. qts.) of water remain.

COOLANT

The coolant warning lamp lights up as soon
as the coolant level in the expansion tank drops

below the minimum permissible level. The
warning lamp may come on when the car is
started and then go out again after a short
time. This is due to the volume of the coolant
increasing as it warms up, and thus exceeding
the minimum permissible coolant level.

It is essential to top up the coolant and, if ne­cessary, to have the cooling system checked
for leaks.

Trailer Indicator Light

The blinker warning light for the trailer opera­tion flashes at the same frequency as the blin­ker lights. Should a trailer blinker fail the fre­quently is noticeably quicker.

25

Oil Pressure Gauge

Voltmeter

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

Should the oil pressure suddenly drop while
driving or should the red oil pressure warning
light come on, the engine should be turned off
immediately. If the oil level is correct the next
workshop should be called in to rectify the
fault.

26

Warning Light

The warning light comes on when the ignition

is turned on and goes out as soon as the cor-

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

In this case stop immediately.

If the oil level is correct the next workshop

should be called in to rectify the fault.

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

mally stay in the range 12-14 volts when the
engine is running. A temporary drop under 12

volts when starting the engine is normal.

Warning Light

The warning light checks the function of the
alternator. It comes on when the ignition is

turned on and goes out as soon as engine rpm.

are high enough. If the warning light flickers or
comes on during driving, it can mean that the
fan belt is loose or broken. The fault could also

lie however in the regulator or the alternator.

In the latter cases the journey can be conti­nued but only to the next workshop. Electrical
consumption should be kept to a minimum.

Warning Lights

(see also "Central Warning Unit")

BRAKE FLUID

The warning light blinks when the fluid level

drops below the allowable minimum.

BRAKE PAD
The light comes on when brake pads are worn

down to the allowable minimum.

BRAKE PR

The light blinks when one brake circuit fails.

PARK BRAKE

The light comes on when the handbrake is on
or not fully released.

ENGINE OIL

With the vehicle level and the ignition turned
on, the warning light will come on if there is
less than 6 liters (1.32 Imp. galls.) of oil in the
sump.

Rear screen heating

The heating for the rear screen and outside
mirrors is operated by the combined twist­push-pull switch in the instrument panel. The
switch is illuminated when the heating is on.

Switch in the pushed-in position

When the hazard light switch is operated, all
4 flashing lights flash simultaneously.

The hazard light switch is operative in any of
the ignition switch positions.

Direction indicator- Dip - Parking
light - Headlight flasher switch

This switch operates the headlight flasher, the
dipped and main beams, the direction indica­tors and the parking lights.

Direction indicator

Push the lever upwards beyond the over­centre position - Right blinker.

Push the lever down beyond the over-centre
position - Left blinker.

If the lever is only pushed to the over-centre
position, the blinkers only operate until the
lever is released.

The malfunction of a blinker light is apparent
by a faster flashing rate. The direction indica­tors only operate when the ignition is on.

With the ignition key removed, the lever in the
up position turns the right hand parking lights
on, and in the down position the left hand park­ing lights.

Parking lights are the front and rear sidelights
of the respective side.

Main and dipped beam

With the light switch in position 2, main beam
is selected by pushing the lever towards the
instrument panel, and dipped beam by pulling
the lever back towards the steering wheel. With
main beam selected, the blue light in the instru­ment panel comes on.

Headlight flasher

The headlight flasher is operated by pulling
the lever right back towards the steering wheel,
and the headlights stay on as long as the lever
is held in this position. The headlight flasher
operates also when the vehicle lighting is not
on.

Tempostat

(Automatic speed control)

The Tempostat will maintain any desired
speed with the range 50-200 km/h (30 to
120 mph) without your foot being on the ac­celerator. Independent of this, you can
brake, change gear and accelerate as nor­mal.

The operation of the Tempostat is controll­ed by the antenna lever behind the wiper
antenna.

The speed being travelled at any point in
time can be fed into the electronic control

unit by moving the lever forewards (position

1).

You can then take your foot off of the acce­lerator and this speed will be maintained.

By braking or stopping, the unit cuts itself
out, but the last speed fed into the unit re­mains registered. This registered speed can
be recalled by moving the lever downwards

(position 2). However, should the ignition be
turned off, the registered speed is cancell­ed from the unit.

If the registered speed is too low, you can
increase speed with the accelerator or by
moving the lever forewards to position 1 and
holding until the desired speed is attained,
and then letting the lever free. This speed is
now fed in to the unit and registered.

If the registered speed is too high, pull the
control lever towards the steering wheel
(position 3) or brake; this interrupts the Tem­postat control, until the required lower

speed is attained, and then move the lever

forewards to position 1. Again this new

speed is registered and maintained.

Note: When you depress the clutch, the
speed control is interrupted, but when the
clutch is released, the speed control takes
over again.

To avoid accidentally overrevving the engi-

ne, do not move the gearshift lever into neu­tral at road speed above 50 km/h (30 mph)
while the cruise controle is engaged.

If you exceed the speed registered in the
control unit, e.g. during overtaking by using
the accelerator, as soon as you come off of
the accelerator, the registered speed will be
automatically resumed. On a steep incline
either up or down, it is possible that the ve­hicle will not maintain the registered speed
in a high gear, then you must change down,
to avoid labouring the engine by uphill, or to
ensure sufficient engine retardation by
down hill driving.

We do not recommend use of the tempostat
in heavy traffic or when road conditions are
unsuitable (eg. winding or slippery roads).

5 Wipers and washers. By pulling the lever

towards the steering wheel, the electric
washers as well as the wipers are switch­ed on.

6 Head lamp washers. By pushing the lever

towards the instrument panel, the head­lamp washers are operated, but only when
the headlights are on. Refer to paragraph

on headlamp washers.

Wipewash lever

The wipewash lever has 6 switch positions.

0 Wipers off

1 Slow wipe

2 Fast wipe

3 Very fast wipe

4 Delay wipe. The wipers operate automa-

tically at regular intervals. The delay inter­val can be adjusted by turning the knurled
knob A under the right hand side of the
instrument panel.

The windscreen should be sufficiently wet
before the wipers are actuated to avoid
scratching it. The wiper blades should be
checked regularly, and replaced at least
once a year.

Concentrated washer system

With the concentrated washer system, even
dirt embedded in siliconbased polishes can
be removed from the screen.
A short press on the switch Β under the right
hand side of the instrument panel causes
the concentrated Porsche cleaning solution
to be pumped onto the screen. The duration
of the spray is controlled by a time relay to
avoid too heavy consumption of the solu­tion. If necessary the operation can be re­peated.
The windscreen washers and wipers can
then be operated to finish off the cleaning
process.

Central Warning Unit

Priority 1 - The central warning light flashes

together with the individual warning light.

The following functions have priority 1:

Brake circuit failure, Brake fluid level, Oil
pressure, Oil level.

If a malfunction is indicated here the vehicle
must be stopped and turned off immedia­tely. The fault must be rectified.

Functions that do not require immediate
attention are:

Priority 2 - The central and individual warn­ing lights come on continuously.

The following functions have priority 2:

To increase driving and operational safety
an automatic warning system has been
developed, that shows the driver, via an
unmistakeable warning light that comes on
in the instrument panel, that there is a pos­sible malfunction. This is done automatically
without the driver having to do anything.

The warning lights for the various functions
are located in the Combi-instruments.

32

Should a malfunction occur the central
warning light in the instrument console will
come on. At the same time the light for the
individual function will also come on, indicat­ing what is malfunctioning.

The function control is divided into two
priority groups. Functions that are essential
for driving and operational safety are:

Brake pad wear, Hand brake, Cooling fluid
level, Cooling fluid temperature, Fuel tank
reserve, Screen washer water level, Brake
lights, Tail lights.

These functions show the need for part
replacement, re-filling, change of driving
mode or release of the handbrake, but not
for an immediate halting of the journey or
visit to a workshop.

With the ignition turned on (engine not run-

ning) all individual warning lights and the

central warning light must come on to indic-

ate operational readiness. 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 vehi-

cle level.)

The warning light for the brakelights must go

out with the first brake application. The

remaining lights go out when the engine is
started.

By pressing the button (arrow) in the middle

of the console the central warning light can

be turned off in the case of priority 2 mal-

functions. It cannot be turned off in priority 1

cases because immediate action is neces-

sary to rectify the fault.

When the handbrake is applied or not fully

released the central warning light cannot be
turned off. Only when the handbrake is fully

released does the central warning light go

out.

Note: If the vehicle is tow or roll started the
warning lights will not go out. The engine

must be turned off and restarted with the

ignition key.

33

Ventilation grills

1 De-icing jets for windscreen
2 De-icing jets for side windows
3 Fresh air jets for passenger compart-

ment
4 Fresh air jets for footwells
5 Air jet in glove box

The height of the jet stream can be altered
by tipping the horizontal bars in the grill. The
lever in the grill adjusts the lateral air flow.

34

Central air inlet grills

The central air inlet grills provide ventilation
for the interior. If the air flow should become
uncomfortable the central air inlet grills can
be closed by means of a lever mounted at
the side of the grills.

In the defrost position the grills are closed

automatically.

Side air inlet grills

To avoid misting up of the side windows, air

inlet grills are built into the door trim panels.
The direction of the air stream can be adjust­ed by the grills, and the airflow can be regu­lated by a lever.

A- Air inlet grill closed
B- Air inlet grill open

35

Automatically controlled
air conditioning

The air conditioning only functions with the
engine running. The cooling effeciency is
dependent on engine revolutions. If more
cooling is required it is necessary - especial­ly in city or stop-go conditions - to increase
engine rpm.

By automatically controlled air conditioning
the air conditioner compressor is switched on
automatically in position AUTO and Bl. The
engine runs at a higher idle speed in this po­sition.

36

A maximum cooling effect is achieved with
the fan switch at pos. 4, the windows closed
and the side and center vents fully open.
When the air conditioner is switched on ad­ditional cooled air is fed via a vent to the glo­ve compartment.
If the vehicle has stood for a long time in di­rect sunlight, it is recommended that the air
conditioning be turned on with the windows
open, to provide through ventilation.

The air conditioning must be operated for a
short period at least once a month.

This is especially important during the cold
weather when the air conditioning is not
needed.
This operation is necessary to lubricate the
expansion valve and the seals on the main­shaft.

Should the air conditioning become defec­tive, that is to say if warm air comes from
the inlet grills, the air conditioning must be
turned off immediately or otherwise the
cooling compressor can be damaged.

The automatic controls the temperature in­side the car according to the programme
chosen and the temperature control lever
position.

The interior temperature is kept constant
even under changing climatic conditions.

Cold and warm air is blended automatically
by means of air mixer valves which are ope-

rated by a servo motor. The servo motor is
switched and controlled via inside and out­side temperature sensors as well as the
coolant thermometer.

The following controls make an individual re­gulation of the air conditioning possible:

Temperature control lever for adjusting the

required interior temperature with tempera­ture scale. The adjusted temperature is
equal to the temperature in the middle of
the vehicle interior.

As heat output is dependent on the coolant
temperature, the full heating capacity is deli­vered only after the engine has reached nor­mal operating temperature.

Programme control lever to enable the au­tomatic air conditioner to meet individual re­quirements several programmes are avail­able.

Air conditioner and blower fan
switched off.

Automatic heater control. No cool­ing is possible on this position be­cause compressor is switched off
for fuel ECOnomy. This program­me is recommended when out­side air temperatures are below

+5° C (40° F).

37

An airstream is also

directed toward the windshield.

Automatic temperature control.
Heating and cooling (during normal
weather conditions). Air is distri­buted according to a predetermined
programme to suit the outlet tem­perature. The center vent may be
closed manually.

Same as position AUTO in addition
the defrost vents are opened. This
position is recommended during
wet and humid weather (rain, heavy
snowfall) to prevent the windscreen
from fogging up. It also provides
better cooling at head level and in
the footwells when outside air tem­peratures are very high.

Defrost position: provides fastest
possible defrosting of the iced or
fogged up front screen and side
windows. With this programme the

maximum heating effect and high­est blower fan speed are switched
on automatically and the full air flow
is directed to the windscreen and
the side vents. The center vent is
closed automatically.

To prevent uncomfortable draughts, in posi­tions the auto­matic control first comes into operation at cool­ant temperatures above approx. 45° C. Below
these temperatures the uncooled fresh air is
prevented from entering the footwell by a cold
start shut off device.

Blower fan switch

To provide air circulation when the vehicle is
standing still or at low speeds the blowerfan
runs at low speed even when the switch is in
the 0 position. Should you require increased
air flow the blower fan can be switched from
positions 1 to 4.

38

Tensioning the V-belt

Checking cooling medium level

The tension of these compressor V-belt is
checked every 20.000 km. If the airconditio­ner is used frequently the V-belt tension
should also be checked between the ser­vice intervals.
The three mounting bolts (A) must be
loosened for tensioning the V-belt. Correct
the V-belt tension with tensioning nut (B)
and tighten the mounting bolts (A). The V­belt is correctly tensioned when it can be
depressed approx. 5 mm using thumb pres­sure, between both V-belt pulleys.

Due to the fact that the system loses cool­ant it is necessary to check the coolant level
at the reservoir at least once a year.
Should air bubbles be visible at the inspec­tion glass of the reservoir (arrow) for an
extended period, with the air conditioner
switched on, this indicates a lack of coolant.
Air bubbles will be normally visible for a short
time.

If necessary have the system re-filled in an
appropriately equipped service workshop.

39

Headlight beam regulator

The height of the headlight beams can be re­gulated to the laden condition of the vehicle
with the knob (B). This enables maximum
road illumination without dazzling other road
users.

The normal headlight beam setting is obtain­ed by turning the rotary knob as far as the
noticeable stop, i. e. the white dot must be
in line with "0" (see also "Headlight adjust­ment").

40

The beam setting must be corrected as

shown in the table when the vehicle load is
increased. Turning the knob clockwise rai­ses the beams and vice versa. The correc-

tion should be checked by observing the

dipped beam cut-off (e. g. on the back of the
vehicle driving ahead of you).

Loudspeaker balance control

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).

Cigarette lighter

The element is heated by pushing the light­er in. When the correct temperature is
reached, the lighter springs out to the
normal position. With the lighter out, the

socket can be used for electrical auxiliaries

such as compressor or handlamp, with a
consumption of up to 120 watts at 12 volts.

Clock

The left-hand push-button beneath the dis­play is used for setting the hour. The right-hand
push-button is used for setting minutes.
A brief press of a button (best done with a ball
point pen) will put the time forward by one hour
or one minute.
Prolonged pressure on the button(s) will cause
the hours and/or minutes to be displayed in
sequence.

In order to set the time accurate to the very
second, press the minute button at the very
moment you hear the time signal on your car
radio.

Ashtray

The ashtray is mounted in the middle con­sole in front of the gear lever. To empty the
ashtray pull the tray upwards out of the
housing.

Rear seat storage compartment

The storage compartment is opened by

pressing the button and lifting the lid. For
security reasons, the storage compartment
is lockable.

On vehicles with a rear seat storage com­partment a second ashtray can be found on
the tunnel in front of the compartment.

41

Electric Sliding Roof

Manual Operation

The sunroof is operated by a spring loaded
rocker switch on the middle console. Appro­priate movement of the switch opens or
closes the sunroof. When released the
switch returns to the neutral position and

the roof stops in the required position. The

drive mechanism is equipped with a safety
clutch which disengages when a certain
resistance is met, thus excluding the possi­bility of accidental injuries.

42

We do not recommend that the sliding sun
roof be operated at speeds in excess of 100
km/h. The force required to overcome the
resistance of the air pressure at higher
speeds can cause damage to the sliding
roof.

A hand crank is provided for manual opera­tion in the event of an electrical failure. To do
this the cover of the sunroof drive must be

removed. Pull the cover down at the rear and
unhook the spring. Unscrew the now visible

slotted screw with the screwdriver tip of the

hand crank. Before inserting the fork-end of

the crank remove spacers which were under
the screw. Turn the knurled screw of the
crank into the threaded hole in the drive

Rear screen wiper

shaft making sure that the lugs engage in the
slots. The roof can then be moved by turning
the crank.

If the roof is only about half open, it is recom­mended that you close the roof by turning
the slotted screw instead.

The rear screen wiper is switched on by a
press switch in the middle console. To pre­vent the rear screen from becoming
scratched it should be sufficiently wet
before operating the wiper.

The wiper motor is mounted in the bodywork
of the vehicle and not in the luggage com­partment door, and drives the wiper with a
clutch, that disengages and engages auto­matically when opening or closing the door.

43

Glove box

Sun visors

Make up mirror

The glove box is opened by pulling the
handle set into the lid. For security reasons,
the glove box is lockable.

44

The front sun visors can be either pulled
down in front of the screen or swung to the
side in front of the door windows to prevent
dazzle from the sun.

The rear sun visors can be swung back to the
rear window.

The make up mirror can be found on the rear
side of the passengers sun visor. On vehic­les with leather interior a lighted make up
mirror is installed in the roof lining behind the
passengers sun visor (except on vehicles
with sun roof). By pressing the button the
mirror swings out from the roof lining.

Luggage compartment door

(See notes under "Alarm system" if your car
is equipped with an alarm system.)

To open the door

Insert key into the lock and turn it to the right
and lift the door. Two gas-struts will then
open the door fully.

To close the door

Push the door down until it can be heard to

lock.

Never drive with the luggage compartment
door ajar or open, as then exhaust fumes
could enter the vehicle.

Engine compartment Hood top

To release the hood

Pull the lever on the left hand cowl side
panel underneath the instrument panel.

To open the hood

Lift the hood top slightly and release the
safety catch by pressing the lever upwards.

Make sure the windscreen wipers are not
tilted forward!

When the vehicle lights are on, a lamp on the
underside of the hood top lights automati­cally.

45

Manual gearbox

The fully synchronised gearbox permits
rapid gear changes without the need to
double declutch. Be sure however that the
clutch is fully depressed before engaging or
disengaging a gear.

The gear positions are shown in the diagram
on the right.

46

Reverse should only be selected after the
vehicle has come to a complete stillstand.

To shift from 1 st into reverse gear, the gearshift
lever must first be moved into neutral position
between 4th and 5th gear.

With the ignition on, the reversing lights
come on automatically when reverse gear is
selected.

Permissible rpm before shifting down.

5-4 gear 4800 rpm
4-3 gear 4800 rpm
3-2 gear 4700 rpm
2-1 gear 4400 rpm

Automatic gearbox

The automatic gearbox facilitates the driv-

ing of the vehicle. The individual gears are
selected automatically, depending on the
position of the gear selector lever, the
speed of the vehicle and the position of the
accelerator.

For safety reasons, the motor can only be
started with the selector lever in positions Ρ
or Ν.
The selector lever has six positions, and is
fitted with a mechanical lockout, to avoid in­advertent selecting of the wrong gear.

The lockout button must be pressed when

changing from

At speeds in excess of 15 km/h (10 mph) a
hydraulically operated mechanical lockout
avoids changing into R or P.

The selectorlever console is illuminated.

Operation

Before selecting a gear with the engine run-

ning and the car stationary, either the hand­brake must be on, or the footbrake operat­ed. The brakes should only be released
when you wish to drive away, as the vehicle
will creep as soon as gear is selected. Do not
accelerate while selecting a gear.

At speeds in excess of 50 km/h (30 mph) Ν
should not be selected. Should however Ν
be selected inadvertantly during driving, the
accelerator should be released to allow the
engine to attain tickover revolutions, before
the gear is selected again. This avoids over­loading the fluid clutch.

It is extremely important for correct func­tioning of the automatic gearbox, that the
correct fluid level is maintained. For this
reason you should check the fluid level fre­quently, between the normal servicing of
the vehicle.

If there is no automatic transmission fluid in
the gearbox or the torque convertor, the
engine must not be started, nor must the

vehicle be towed.

The automatic gearbox and the torque con­vertor are both filled with ATF, simultaneous­ly. The back axle is filled with Hypoid oil. For
filling amounts see the chapter "Filling capa­cities".

47

Selector positions

D

This is the gear to select for normal driving.
The three forward gears are automatically
engaged, according to the load on the
engine and the speed of the vehicle.

2

This is the gear to select for mountainous
terrain, as well as for long uphill or downhill

stretches. The engine's power is better uti­lised, and also the retardation affect of the
engine is greater. The vehicle pulls away in
1st gear and changes automatically into 2nd
gear. 3rd gear is locked out. During driving,
this position can be selected, even with the
accelerator depressed. However, as 2nd
gear is then immediately engaged, this

should not be done at speeds in excess of

150 km/h (90 mph).

1

This position should be selected when it ap-

pears advisable to hold the vehicle in 1st
gear, e. g. steep up or downhill stretches, or
when operating with a trailer in mountainous
terrain.
The vehicle remains in 1st gear, and 2nd and
3rd gears are locked out.

This position can be selected from position
2 during driving by pressing the lockout but­ton, but should only be done at speeds
lower than 60 km/h (35 mph).

Ρ

Must only be selected when the vehicle is
stationary.

In this position, the driving wheels are me­chanically locked. To select Ρ the lockout
button must be pressed.

Ρ should only be selected after the hand­brake has been applied, and should be dis­engaged before the handbrake is released.
The engine can be started in this position.

Ν

In this selector position, no gears can be
engaged. It is the same as neutral in a man-

ual gearbox, and should be selected when
the vehicle is stationary for any length of
time, e. g. traffic jam. This position should
only be selected when the engine r. p. m. are
at tickover.

The engine can be started in this position.

R

This position must only be selected at tick
over, and with the vehicle stationary. The
lockout button has to be pressed to select
R. At speeds in excess of 15 km/h (10 mph) a

hydraulically operated lockout prevents R
and Ρ from being engaged. With the ignition
on, the reversing lights come on automatic­ally when R is selected.

48

Waiting Trailer operation

For short waiting periods, e. g. traffic lights,
the vehicle can be left in gear, and held sta­tionary with the footbrake.

For longer waiting periods, with the engine

running, position Ν should be selected.

Never hold the vehicle stationary on a hill
with the accelerator. Always apply the hand

or footbrake.

This avoids unnecessary warming up of the
torque convertor or gearbox.

Stop start driving

For stop start driving, e. g. traffic jam, posi-

tion 1 should be selected.

Parking

When parking, or manouvering in confined

spaces, the speed can be adjusted with the

brakes, and very little acceleration is requir-

ed.

Selector position 2

For inclines, up or down, select position 1 in
good time, to attain maximum engine power
or retardation, and thereby reduce the load­ing on the brakes. For mountainous terrain
only use selector position 1.

Being towed

When the engine is not running, the oil pump
for the automatic gearbox is not driven, and
therefore the gearbox is not lubricated. The
following points must therefore be noted:

1. Selector

2. Towing speed must not exceed 50 km/h
(30 mph).

3. Maximum towing distance 50 km (30
miles).

4. For greater distances, the vehicle must be
transported on a trailer.

Tow or push starting

If your Porsche is fitted with automatic gear­box, it cannot be tow or push started.

in position N.

49

The shift points given here are theoretical road speeds. There may be certain variations in practice as a result of ma-

nufacturing tolerances, the temperatures of components and automatic transmission fluid as well as tyre slip.

Up shifts

In selector position "D" the automatic up
and down shifts are dependent on a combi­nation of road speed and accelerator pedal
position. The shift points vary between the
part throttle and full throttle positions.

50

A) When you drive with a gentle pressure on

the accelerator pedal the transmission
shifts from 1 st to 2nd gear approx. 30 km/h
(20 mile/h) and into 3rd gear approx. 45
km/h (28 mile/h) in order to preserve fuel
and reduce noise levels.

B) During full throttle acceleration or kick-

down the transmission holds 1st and 2nd
gears longer for better acceleration. It then
shifts from 1st to 2nd at approx. 100 km/h
(60 mile/h) and into 3rd gear at approx. 160
km/h (100 mile/h).

The shift points given here are theoretical road speeds. There may be certain variations in practice as a result of ma­nufacturing tolerances, the temperatures of components and automatic transmission fluid as well as tyre slip.

Down shifts

A) When you drive with gentle pressure on

the accelerator pedal the transmission

shifts down from 3rd to 2nd gear at approx.
35 km/h (23 mile/h) and into 1st gear at ap­prox. 20 km/h (12 mile/h).

B) When you drive at full throttle the trans-

mission shifts down from 3rd to 2nd gear

at approx. 80 km/h (50 mile/h) to provide
better acceleration or hill climbing ability
on gradients and then shifts to 1st gear at
approx. 50 km/h (30 mile/h).

C) If you press the accelerator pedal down

beyond the pressure point to actuate the
kick-down switch, the down shifts take

place at higher road speeds to provide ma­ximum acceleration. The down shift from
3rd to 2nd gear takes place at approx. 130
km/h (80 mile/h) and 1st gear is selected
at approx. 70 km/h (45 mile/h). The up-shift
points for kick-down acceleration are the
same as those given for full throttle acce­leration.

Tips for "Running-in" Maximum permitted revolutions Roof Racks

There are no particular rules to be observed
when "running-in" your new Porsche, how­ever the following tips will be helpful in ob­taining the optimum running properties.

Despite the most modern manufacturing
methods with their high precision, it cannot
be completely avoided that the moving
parts have to wear in with each other. This
wearing-in occurs mainly in the first 1000 km
(600 miles).
Oil consumption can be somewhat higher
than normal during the "running-in" period.

Therefore you should

never over-rev a cold engine, either in neu­tral or in gear,

continually change the demands made
upon the engine and transmission,

never exceed 5000 rpm in the individual
gears,

always change gear in good time, and there­by keep the engine in the optimum revolu­tion range (note the Transmission diagram).
This of course also applies after running-in.

The red range on the rev-counter scale is a
visual warning.

When the maximum permissible engine speed
is reached, the governor built into the distri­butor cuts off the ignition current, and thereby
prevents the engine from being overrevved
during acceleration.

Bedding-in new brake pads

New disc pads have to bed-in, and do not
therefore have the full braking ability in the

beginning. To compensate for this reduced
braking ability for approx. the first 200 km
(120 miles) a little more pedal pressure is
necessary. This also applies after having the
disc pads renewed at a later date.

Please note: New tyres do not posess their

full road-holding ability. Therefore only

drive at lower speeds for the first 200 km
(120 miles).

Normal commercially available roof racks

cannot be fitted.

If an original Porsche rack (as available hit­herto) is fitted, the permissible roof load is 35
kg. With the "New Porsche Roof Transport
System" you can transport a wide variety of

sports and hobby equipment, up to a roof load
of 75 kg. There are many different racks to
choose from.

Your Porsche dealer will be glad to advise you

on the versatility of the "New Roof Transport

System".

To ensure minimum noise, maximum econo-

my and a desirable level of safety when driv-

ing with an unloaded roof rack, you should not

exceed a maximum speed of 180 km/h.

When the roof rack is loaded, the recom­mended maximum speed depends on the na­ture, size and weight of the load. You should

not however exceed a speed of 140 km/h at
any time. Make sure that the load is firmly and
securely fastened.

Tips for winter operation

Engine oil Cooling fluid

Before the onset of the colder weather, have
the engine filled with oil of the correct visco­sity. See chapter on "filling capacities".

Battery

The battery capacity drops with lower tem­peratures, but the demands made upon the
battery generally increase. Therefore, have
the battery checked and charged, if neces­sary, in good time. Also have the acid con­tent checked, and the terminals greased.
See chapter "Check and care of battery".

Corrosion protection

The salt spread on winter roads can have a
detrimental effect on your car's bodywork.
You should therefore wash the car as often
as convenient in accordance with our care
instructions. Have a preservative applied
and the underseal checked in an authorized
workshop before and after the cold weather
season.

The vehicle should not be driven without
anti-freeze at temperatures below freezing
point. The all-season cooling fluid in the
cooling system, put in by the manufacturer,
offers protection down to -30°C (Northerly
lands -40°C).

Nevertheless it is advisable to have the cool­ing fluid checked to make sure that the ne­cessary protection is afforded, at the onset
of colder weather. When necessary, top up
with antifreeze. For amounts see chapter
"Filling capacities".

Brakes

After driving for extended periods on salt
covered roads a film can form on the brake
discs and pads which considerably reduces
friction and thus the braking effect.

Door and window seals

To prevent the freezing of the rubber seals
on the doors and hood top, they should be

treated with talcum powder or glycerine.

Door locks

To prevent the door locks freezing up, the
lock cylinders should be masked when
washing the vehicle, to avoid ingress of
water. Should however the locks still freeze
up, a proprietory de-icing solution can be
used to free them. A warmed-up key can
also be useful, but never use force.

53

Water reservoirs

To ensure the function of the screen and
headlight washers under frost conditions,
anti-freeze should be added to the water. A
mixture of one part household spirit to three
parts water also works very well.

Winter tyres and snow chains

Due to the reduced effectiveness of sum­mer tyres in winter we recommend the fitt­ing of special winter tyres when snow and
ice are expected.
If M + S tyres are used in the winter, they
must be fitted to all 4 wheels. Be acquainted
with the different laws in different lands gov­erning maximum speeds with these tyres.

54

Snow chains can only be mounted on the
driving wheels, and only the fine link chains
recommended by Porsche for the normal
series tyres should be used. This ensures
that the clearance between the wheel and
wheelhouse is maintained. However, note
the chain manufacturers recommendations.
Your authorized dealer will be pleased to
advise you in choosing the appropriate win­ter tyres and snow chains.

Additional equipment

It can be helpful during winter to keep a
handbrush and scraper in the vehicle, to

clear the screens of ice and snow, as well as
a board to put under the jack and some dry
sand to help traction when pulling away on
icy slopes.

Car care instructions

Regular and correct care helps to maintain
the value of your car and is also a precondi­tion for the long-life guarantee.

Washing

The best method of protecting your car from
the damaging effects of the environment is
frequent washing and the re-application of a
preservative.

The salt spread on winter roads, road dust

and dirt, airborne industrial emissions, dead
insects, bird droppings etc. can have a da­maging effect on the bodywork if allowed to
remain on the car for a long time.
Salts have a particularly corrosive effect on
body seams, flanges and joints.
It is therefore necessary to clean such areas
thoroughly with a sponge when you wash
the car - or after going through an automa-
tic car wash, then rinse them with water and
rub dry with a leather.

New cars should be washed carefully with

plenty of clear water to protect the fresh
paintwork. Dark paint finishes show up the
smallest of surface damage (scratches) mo-

re readily than light colors. Dark colors are
also slightly more susceptible to scratches

because the composition of their pigments
and therefore require special care and at­tention.

Use an abundant supply of water, a soft
sponge or wash brush and a suitable, mild
car shampoo. Begin by spraying the body

thoroughly with water to rinse away loose

dirt. Do not wash your Porsche in bright sun-

light or while the bodywork is still hot. After
washing, rinse the car plenty of water and
then leather dry. Remember to clean the
seams, flanges and joints!

Do not use the same wash leather for rub-

bing down as you use for cleaning the wind­shield and windows.
The moisture which gets on to the brakes
during a car wash can reduce braking effi­ciency or make the brakes pull unevenly. Al­ways test the brakes a few times after wash-

ing your car to make sure they are properly
dried off.

Dust should never be wiped off the car with a
dry cloth since dust particles are abrasive
and could dull and damage the surface fin­ish.

Preservation

The paintwork contains certain fats which

maintain its high lustre and prevent it be­coming brittle. Climatic effects can remove
these fats from the paintwork. This should be
counteracted by applying a paint preservati­ve in good time to restore the fats and thus
retain the high lustre.

Please use only the preservatives and wash­ing agents recommended by your Porsche

dealer. Provided it is washed and treated
with preservative regularly, the brand new
finish of your car will be retained for years to
come. Apply the paint preservative after the
car wash and polish it dry to obtain a bright
finish or simply add a preservative to the fi-

nal rinse water and rub down with a leather.

Polishing

The use of polishes is recommended only af­ter it becomes evident that the normal pre­servatives no longer produce the desired fi­nish.

Caution: Do not apply silicone polishes to
the windshield or windows.

The paintwork of your car is exposed to all

manner of mechanical and chemical stres-

ses, particularly climatic ones such as bright
sunlight, rain, frost and snow. Ultraviolet

light, rapid changes in temperature, rain,
snow, industrial dust and chemical deposits

constantly attack the paint which is only ab­le to withstand such exposure in the long
term if it is given regular care and attention.

Matt painted parts should not be treated
with preservatives or polishes as this will
spoil the matt effect.

55

Spots and stains

Tar stains, grease, oil spots and dead insects
cannot always be removed by washing alo­ne. They can cause discoloration if allowed
to remain on the paintwork. They should
therefore be removed without delay with a
suitable cleaner (tar, stain or insect remo­ver). Wash the affected area immediately af­ter treating it.

Minor paint damage

Minor paint damage, such as scratches, sco­res or chips caused by flying stones, should
be covered immediately with paint before
corrosion sets in. However, if there are alrea­dy traces of corrosion they must first be re­moved carefully and thoroughly. Coat the
area with a rust-proofing primer (applicator
or aerosol) and finish off with a top coat. The
paint code and color number are found on a
label close to lock on the left door pillar.

Undersealing

The underside of the car is durably protect-

ed by a factory-applied undersealing mate­rial.

As it is not possible to exclude the risk of da-

mage to this protective coating in day-to­day driving, it is advisable to have the under­side of the car inspected at certain intervals

- preferably before the start of the cold sea­son and again in the spring - and the under­sealing repaired as necessary.
The oil industry has developed undersealing
and rust-proofing compounds based on bi­tumen or wax. Unlike conventional spray
oils, these preservatives do not attack the
anti-drumming materials applied at the fac­tory.

Before applying fresh underseal, carefully
remove deposits of dirt and grease. Once it
has dried the new undersealing compound
forms a tough protective coating which pro­vides efficient rust-proofing of the floor pa­nels and components.

Always apply a fresh coating of suitable
preservative to unprotected areas after
cleaning the underside of the body or the
engine or carrying out repairs to underbody
components.

Your Porsche dealer is familiar with the bo­dyseal treatment procedures and has the
necessary equipment for applying factory­approved materials. We recommend that
you entrust him with all such work and in­spections.

Cleaning and preserving engine compart­ment

The engine compartment and the surface of
the engine are treated with a corrosion inhi-

bitor at the factory. If grease solvents are
used for cleaning the engine compartment
or the engine itself, they invariably destroy
the corrosion inhibiting coating. It is then ab­solutely necessary to have a durable preser­vative applied to all surfaces, body seams,
joints and components in the engine com­partment.

Grease the return springs of the accelerator
cable after every engine wash.

Effective rust-proofing is particularly impor­tant during the cold weather season. If the

car is driven frequently in areas where salt
has been spread on the roads, the whole en-

gine compartment should be cleaned tho-

roughly after the cold weather season to
prevent the salt causing any lasting damage.
A full underbody wash should be performed
at the same time.

Windows

The road dust which settles on the wind­shield and windows contains particles of tire

rubber and oil residue. The interior trim and

upholstery gives off deposits, particularly in
strong sunlight, which collect on the insides
of the windows. These deposits are aug-

mented by impurities in the air which enter
the car through the fresh air vents.

A luke-warm soap and water solution or a
normal window cleaner can be used for
cleaning the insides and outsides of win-

56

dows. Remember to clean the wiper blades
as well. If you use a chamois leather for the
windows, do not use it for the paintwork as it
will otherwise pick up a certain amount of
preservative or polish and could smear the
windows and thus impair vision. Use a spe­cial sponge for removing dead insects from
the windshield.

In winter a cleaning and anti-freeze agent
must be added to the water used by the wind­screen washer system. These agents are to
be added in the ratio specified by the manu­facturer.

Lights, plastics

Use only a soap and water solution for clean­ing the plastic light lenses. Never use che­mical cleaning agents for this purpose. The
same applies to other plastic parts and fi­nishes.

Door, lid and window seals

Rubberseals tend to age and become brittle
or crack if they are not treated occasionally
with glycerine or talcum powder.

Aluminum wheels

Pitting can occur if metallic particles which
cause contact corrosion (e. g. brass or cop­per in brake dust) are allow to remain on the
aluminum for too long.

Regular care is necessary in order to retain
the attractive surface finish. The wheels
should be washed down with a sponge or
wash brush about every two weeks. In areas
where salt is spread on winter roads or there
is a lot of airborne industrial dust, it is best to
clean the the wheels weekly. Non-acidic clean­ing agents with a maximum pH of 10 may be
used for this purpose.

Every three months you should coat the
wheels with a non-corrosive grease (vaseli­ne) after cleaning. Use a clean cloth to tho­roughly rub the grease into the surface.
Polishes which dissolve oxide, as frequently
used for other metals, or abrasive tools or
agents are unsuitable because they break
down the paint-resp. oxide film.

57

Leather care

Cleaning is best performed with a white, soft
woolen cloth and a weak soap and water so­lution. Don't use aggressive cleaners and
rough cleaning materials. Take special care
not to dampen the other side of perforated
leather trim. Once you have cleaned the
leather (especially the very stressed leather
seats) treat it with »Karneol« preservative ­Porsche part-No. 000.043.007.00 -. Ask your
Porsche dealer for further details.

Care of seat belts

If it becomes necessary to clean the belts,
you can use any mild washing agent. Allow
the belts to dry, but avoid direct sunlight. If
unsuitable cleaners are used or any attempt
is made to dye or bleach the belts, the web­bing may be weakened and thus constitute
a safety risk.

Leather should be cleaned and treated se­veral times a year, depending on how quick­ly it becomes dirty. We recommend that
"Karneol" be applied initially after the first
few weeks or after the car has covered a few

thousand miles.

The natural surface markings of leather
skins, such as creases, healed scratches, in­sect bites and slight variations in shade and
grain add to the attractiveness of the real
leather product.

Fabric upholstery, carpets

Use only a vacuum cleaner or a medium stiff

brush. Remove stains and spots with a luke­warm soap and water solution or a reputable
spot remover.

58

Cleaning the antenna

To ensure perfect radio reception and smooth
action, the telescopic antenna must be clean­ed regularly (weekly) with a soft cloth moistened
with oil. Operate the antenna several times
while cleaning it. Use only light, non-resining
oil, e.g., sewing machine oil, or special anten­na cleaning cloths.

Storing your car

If you intend to store your Porsche for a pro­longed period, please consult your Porsche
dealer. He will be glad to advise you on the
most suitable and necessary methods of
corrosion protection.

Advice on maintenance
and breakdowns

It is strongly recommended that all the ne-

cessary work on your vehicle be carried out

by authorised workshops. The training and
experience of the workshop personnel, the
technical information from the manufacturer
and the special tools and apparatus provide
a good basis for the correct treatment of
your Porsche.

When, however, you wish to work on your
vehicle, this should only be done with great
care. Only then, is the safety of your vehicle
ensured. The engine should always be turn­ed off and cool, before starting work on it.

Before undertaking an oil-change on your
vehicle, you should know how to dispose of
the old oil. Under no circumstances should
it be tipped into the drainage system, over
the ground or into the waterways. If you
cannot dispose of the oil properly, then let
your workshop do the oil-change.

Tool-kit

The tool-kit is in the tray fitted to the back panel
of the vehicle. To remove the panel covering
the tool-kit, both knobs must be turned through
90°. It contains all the tools necessary to re­medy small faults and to enable you to do your
own servicing. The jack is by the spare wheel.

Some lands require that additional tools and
replacement parts be carried in the vehicle.
Please enquire before driving abroad.

The jack supplied with the vehicle should
only be used when changing the wheels on
the vehicle. When working under the
vehicle, it should be supported on purpose-

made stands for safety.

59

Engine oil level

The oil level should be between the two
marks on the dipstick. If the oil level sinks
below the lower mark, the central warning
light will flash when the ignition is turned on.
(See Central warning unit.) The actual oil
level can only be determined however when

the vehicle is standing horizontal.

It is incorrect to check the oil level immedia-

tely the engine has been turned off,

because the circulating oil takes a few
minutes to flow back to the sump. If the level
is on the lower mark, only enough oil should

be added to ensure that the level does not
fall below this mark before oil is checked
again. When the engine is heavily stressed,
as in summer on the motorways with con­stant high speeds, or in the mountains, the
oil level should be maintained near the

upper dipstick mark as the oil has more cool­ing to do.

60

Checking oil level

1. Pull dipstick out and wipe with clean cloth.

2. Push the dipstick fully in, and then pull out
and read the level. The difference bet-

ween the upper and lower marks is ap­prox. 1,5 liter.

Topping up engine oil

1. Unscrew

2. Top up with an oil of the same quality and
of a recognised brand.

3. Check oil level on dipstick, it should not be
over the top mark.

4. Screw the cap up tightly.

the cap and pull out the dipstick.

Engine oil change

Oil level in gearbox

For the intervals between oil changes see the
maintenance plan.

The refill quantity is ca. 7.5 liters.

1. With the engine warm, remove the oil filler
cap and the oil drain plug.

2. Let all the drain out and renew the filter.
When renewing a filter, no undue force
should be used to tighten it, (lightly oil the
sealing ring) as it will then be very difficult
to remove when doing the next filter change.

3. Screw the filter element up until it contacts
the sealing ring.

4. Screw the filter element a further half a turn.

5. Clean the drain plug and replace it, using a
new sealing ring.

6. Pour the new oil in, check the level and re­place filler cap.

7 Run the engine and check for leaks.

8. Run the motor and check for leaks.

To check the oil level in the gearbox, the
plug (B) must be wiped clean and removed
by unscrewing.

With the vehicle standing horizontally, the oil

(cold) should be topped up to the lower lip of

the hole.

To refill the gearbox, only use the oils recom­mended in the table "Filling quantities".

61

Manual gearbox
Oil change

Automatic gearbox

Checking oil level

The level of the oil should be checked re­gularly, even between services.

To check the level, the vehicle must be
standing level. The selector must be in posi-

tion Ν and the engine running at tickover.

The difference between the two marks is ca.

0.2 liter (1/2 pint).

Should oil leakage be visible the next work­shop should be called in to rectify the fault.

Oil change

When changing the oil, ca. 5.5 liters (1.25

Imp. galls.) are required to fill the gearbox
and torque convertor.

The filter must be renewed at every oil

change, and the level must be up to the
mark underneath the min. mark.

To refill, only use the oils recommended in
the table "Filling quantities".

To change the gearbox oil, both drain plugs
(A) must be removed by unscrewing. They
are to be found at the front and back of the
gearbox.

62

The level can be seen through the transpa­rent reservoir, that is mounted on the back
end of the gearbox housing. The fluid level
must be between the max. and min. marks
when at normal operating temperature.

For fluid changing intervals see the mainten-

ance plan.

If too much oil is added, inadvertently, it

must be removed.

Since the expansion tank is transparent, there
is no need to remove the cap to check the
coolant level.

When cold (approx. 20°C) the coolant should

be up to the level of the joint in the expansion

tank. When the engine is warm, the coolant

level should be above this line.

As engine temperature rises, superfluous
coolant is discharged through the pressure
relief valve in the tank cap.

Right-hand drive

Cooling system

The cooling system capacity is approx. 16
liters. The cooling fluid is a mixture of ap­prox. 8.8 liters softened water and approx.

7.2 liters of cooling fluid additive, and gives
frost protection down to -30° C, as well as
protection against corrosion. For greater
frost protection, see the chapter "Filling
capacities".
Therefore, if the needle on the coolant tempe­rature gauge moves into the red zone, for ex­ample when driving fast in very hot weather, it

is advisable to reduce engine speed intermit-

tently.

Left-hand drive

Cooling fan

The cooling fan is driven by a V-belt through a
temperature-controlled, speed-governing
visco-coupling. When the engine is cold, the
fan speed is only a fraction of the engine speed;
when the cooling system is warm, fan speed
is the same as engine speed up to approx.
3500 rpm. The fan speed does not exceed this
value, even at higher engine speeds.

Topping up the coolant

There must always be some coolant in the ex­pansion tank.

WARNING: Do not remove the expansion

tank cap when the engine is hot, otherwise
you may be scalded.

To remove the cap proceed in two steps: When
the engine is hot release excess pressure by
turning the cap to the first stop. Protect your
fingers! The cap can then be turned further to

remove it.

When the coolant level drops below a certain

level the central warning light on the instru­ment panel will light up; the coolant level must

then be topped up.

63

To guard against corrosion, the mixture
strength of the cooling fluid should not be
altered, so even in warm weather, never top

up the system with just water.

The system should only be topped up with a
mixture of soft water and cooling system
additive. For mixing ratios see the chapter
"Filling capacities".

To avoid damaging the engine, cold fluid

should only be added to a cold engine.

Note: There should seldom be need to top
up this sealed cooling systems. If there is a
considerable fluid loss, it probably means a
leak in the system. This should be checked
immediately by an authorised dealer.

64

Draining and refilling the cooling system

1. With the engine cool, set the heating le­ver to "warm" and remove the cap from
the expansion tank.
(On cars with automatic air conditioning,
set temperature slide control to 30°C
(86°F) and switch on the ignition).

2. Remove the drain plug from the radiator,
and catch the fluid.

3. Remove the two drain screws located
left and right in the engine and catch the
fluid.

4. Renew the sealing washers on the drain
plug for the radiator and the two engine

drain screws, and refit.

5. With the engine stationary, refill the sys-

tem as full as possible.

6. Run the engine until it reaches normal

operating temperature, checking the fluid
level constantly. If necessary, top up the
level in the expansion tank to the middle
line.

7. Refit cap to expansion tank.

Left-hand drive

Screenwash water container (A)

The transparent water container is in the
right hand side of the engine compartment
and has a capacity of approx. 8 liters.

It is advantageous when you add a screen
cleaning and anti-freeze agent, in the ratio
recommended by the manufacturer, to the
water. Clear water is in general not sufficient
to clean the windscreen and the headlights.

Brake fluid reservoir (B)

Right-hand drive

bers: one for each of the two brake circuits,
and one for the clutch. The screw cap for the

combined filler neck has a ventilation hole,
which must always be kept free.
The reservoir is transparent, so that the fluid

level can be controlled from the outside. The

level should always be between the max.

and min. marks.
A nominal dropping of the fluid level will oc-

cur during the use of the vehicle as the brake

disc pads wear and automatically adjust.
This is quite normal.

Left-hand drive

tral warning unit.) Consult an authorised
dealer immediately and have the braking sy­stem checked.

Brake fluid is hygroscopic! A too high water

content in the brake fluid adversely affects
the braking system, and therefore the brake
fluid should be changed every two years by
an authorised dealer.
To top up the level, only use new (unused)

brake fluid. For specification and amounts
see the chapter "Filling quantities".

The brake fluid reservoir is mounted in the
engine compartment. It has three cham-

Should the fluid level drop appreciably, the

central warning light will come on. (See cen-

Note: Brake fluid is corrosive, and attacks
paintwork.

65

Container for concentrated
wash system

The fluid reservoir is mounted at the right on
the front bonnet lock cross member and holds
approx. 0.6 liters of cleaning fluid. To avoid
damage to the paintwork, only "Porsche spe­cial silicone remover" should be used. Other
cleaning agents are not suitable for the con­centrated washer system, but if this special
solution is not obtainable, a proprietory solu-

tion can be used, following the manufacturers

recommendations for mixing quantities. "Por­sche special silicone remover" is proof against
frost down to -25° C.

66

Fuel tank

The fuel tank filter is set in the rear quarter

panel behind the right hand rear wheel.

An extra area is built in to stop the fuel from

overflowing when it warms up. This area

should not be filled when filling up with fuel.
After filling up, the filler cap should be screw­ed on until it is felt to be fully home.

When refuelling, the engine should always

be turned off.

The fuel tank holds approx. 86 liters (19
galls.). When the central warning light and
the fuel tank warning light in the instrument

console come on, you should refill the tank.

You have only about 8 liters (7 Imp. qts.) fuel

left.

Fuel

Your Porsche will run on any grade of fuel
with an octane rating of 98 or higher.

To prevent ignition knock (pinging) when driv­ing in countries with low-octane fuel, you
should accelerate gently, change speeds in
good time and avoid driving at top engine

speeds. If you intend to stay in one of these
countries for some time, you should consult
your Porsche dealer regarding adjustment of
the ignition timing.

Power assisted steering

With power-assisted steering, the turning
action on the steering wheel is assisted by a
hydraulic mechanism. At low engine speeds,
e. g. when parking or when driving slowly, the
power-assisted steering is fully effective.

The power assistance reduces with increas-

ing engine revolutions or increasing vehicle
speed and has the effect of producing in­creasingly positive steering action.

The audible rushing noise that occurs at full
steering lock is a characteristic of the con­struction and does not indicate a fault in the
steering assembly.

Note that when the engine is not running

(when being towed) or when the hydraulic

steering mechanism is faulty, there is no

power-assist action present. In this case, a
greater effort is required to steer the
vehicle.

Container for hydraulic fluid

The reservoir is mounted on the left hand
inner wheelhouse in the engine compart­ment.

To check fluid level:

1. Remove cap from reservoir.

2. With the engine running, the fluid level
should be up to the mark in the reservoir. If
necessary top up with hydraulic fluid. To
refill, only use the oils recommended in
the table "Filling quantities".

3. Replace cap on reservoir, ensuring that
the sealing ring sits properly.

1. Release
filter housing complete with filter element.

2. Clean out filter housing and renew the fil­ter element.

3. Carefully replace top of filter housing and
element, and refasten fixing clips.

Tyres and tyre care

Steel braced radial-ply tyres are high quality

engineering products. The life of your tyres
depends not only on correct inflation and wheel
alignment but also on your style of driving: Full
throttle acceleration, very high cornering
speeds and hard braking increase tyre wear.
Moreover, tread wear is greater on rough road
surfaces and in very hot weather. Like the en­gine, tyres need to be run under the correct
operating conditions at all times. If treated pro­perly they will be a long lasting safety element
on your car. The following points demonstrate
what is necessary. Your tyres will thank you for
regular care.

1 Tyre pressure

It is absolutely essential to keep your tyres

at the right pressure.
The tyre pressures are shown in the "Techni-

cal data" and must always be regarded as
minimum pressures!

Always check pressures when the tyres are
cold. Never let air out of hot tyres!
The maximum air pressure of 36 psi stamped
on the tires only applies to the U.S. classifica­tion is not to be confused with normal service
pressures. In Europe, the tire can be inflated
to higher pressures.
Check regularly every 14 days.

2 Valve caps

Valve caps protect the valve against dust
and dirt as well as leaks. Always screw the

caps firmly into position and replace missing

ones immediately.

Check every 14 days.

3 Load and speed

Do not overload your car. Never exceed the
specified roof and trailer coupling loads. A
combination of overload + low tyre pressu­res + high speed + high ambient temperatu­res is extremely dangerous.

4 Winter tyres

Do not exceed the maximum speed limit (e. g.
160 km/h /100 m.p.h. for M + S [Q] radial-ply

tyres).

An appropriate sticker must be affixed in the
driver's field of vision if the tyre's maximum
speed is less than the car's maximum
speed.

5 Tread

The risk of aquaplaning increases as the
tread depth decreases. Appearance of the
wear indicators (webs in tread grooves 1.6

mm high) should be taken as a signal for ear­ly tyre replacement.

Check regularly, particularly before and after

long journeys.

6 Lateral and radial run-out

Take the precaution of having the tyres ba­lanced in spring (summer tyres) and before

the start of winter (M+S tyres). Note that on­ly the specified weights may be used for ba­lancing. (Self-adhesive weights must not co­me into contact with cleaning agents as they

might otherwise drop off.) Uneven tread
wear indicates that the wheel is not running
true. A specialist should be consulted in
such a case.

See also "Wheel alignment".
Uniform tyre wear can be achieved by perio­dically changing round the wheels (e. g. af­ter 5000 km/3000 miles or longer). But only
change the wheels at one side from front to
back and vice versa so that the tyres always
run in the same direction.
Balancing and checking should be perfor­med by a specialist workshop.

7 Tyre damage

Examine tyres at regular intervals for foreign

matter, nicks, cuts, cracks and bulges (side­walls). In case of tyre damage where it is un­certain whether there is a break in the ply
with all its consequences or tyre damage
caused by thermal or mechanical overload­ing due to a loss of pressure or any other
prior damage, we recommended that the ty­re be replaced for safety reasons.
If one faulty tyre is replaced it should be no-

axle must not be more than 30%.

8 Tyre replacement

The tyres approved for your car are listed in
the vehicle log book. Only buy new tyres of the
same make and type which comply with these

specifications. Always replace the tyres on
one axle at a time because

a) the rear axle is more critical from a stabi-

lity point of view and

b) in wet conditions it is the front wheels

which hit deep water first, while the rear
wheels run mostly in the track of the
front ones.

Make sure that new valves are fitted whene-

ver the tyres are changed. During their initial

break in period new tyres do not have their

full grip. It is therefore necessary to run them

at only moderate speeds during the first

100-200 km (60-120 miles). Never use dif­ferent types of tyre. Have tyres fitted by a
specialist.

For this reason you should only drive over
curbs slowly and preferably at right angles.
Take car when parking at or on curbs.

Tire designations

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

9 Curbs

Hard impact against curbs (traffic islands
too) is dangerous. It can result in hidden tyre
damage which only becomes noticeable la­ter on (risk of high speed failure); tyres have
a memory!

10 Tyre storage

Always store tyres in a cool, dry and dark pla­ce. Tyres not on rims should be stood up.
Avoid any contact with fuel, oil or grease.

During the transitional period tires may bear a
dual designation, e. g., 185/70 SR 15 M + S Q.
If so, the valid designation is the new one.

The old designation continues to be used for
VR tires, e.g., 225/50 VR 16 (VR = code letter
for radial tires for speeds above 210 km/h).

69

Spare wheel

The spare wheel is in the luggage compart­ment under a cover plate. Behind the spare
wheel is the jack, and in the spare wheel is
the compressor and a plastic sack in which
the put the changed wheel to avoid making
the luggage compartment or car interior
dirty.

The spare wheel is fitted with a collapsible
tyre, and when it is needed, it must be inflat­ed with the electric compressor to a pres­sure of 2.2 bar (32 psi).

70

The collapsible tyre must only be mounted
on the front axle, which means that if a rear
tyre punctures, the front tyre on that side of
the car must be mounted on the rear, and
the spare wheel at the front. This gives bet­ter handling properties for the vehicle, and
reduced tyre wear. This is especially so for
vehicles with limited slip differentials.

The collapsible tyre expands through warm-

ing up as it is used. When deflating the tyre,
(completely remove the valve core) it requi­res several hours to cool down and thereby
assume it's original form, before it can be
replaced in the well in the luggage compart­ment.

The collapsible tyre can be neither repaired
nor mounted in a normal workshop. All work
on these tyres must be left to the manufac-

turer.

The spare wheel with the collapsible tyre
may only be used in an emergency, for
short distances, and then only on the front
axle. The maximum speed for this tyre is
100 km/h (60 mph) and this speed must not
be exceeded because of the changed
handling characteristics of the vehicle, and
the wearing properties of the tyre. The
same law applies to depth of tread for this
tyre, as for the normal tyres.

Lock-up wheel nuts

The wheels of your vehicle can be made theft-

proof by means of a wheel nut lock. The wheel
nut lock consists of a wheel nut and a plug-on
sleeve with lock. The same lock is used on all

four wheels.

To remove the wheel nut lock, take off the
plastic cap, insert the key as far as it will go into

the lock, turn approx. 90° to left or right and

remove the sleeve with the key.

To fit the wheel nut lock, insert the key as far
as it will go into the lock and slip the sleeve on­to the wheel nut.

Before removing the key check whether the
sleeve is up against the shoulder of the wheel
nut.

When removing the key press the sleeve
against the wheel nut. Fit the plastic cap.

It is not usually necessary to re-balance the
wheels.

Puncture

When a tyre is punctured, drive as far over to
the offside of the road as possible, and if

necessary turn the hazard warning lights on
and set up a warning triangle at the correct
distance behind the car.

The ground should be firm and even before
jacking up the car. The handbrake must be
firmly applied, and the wheels on the other
side of the car should be chocked.

71

Order of working

In the case of a defective rear tire jack the
rear of the car up, after changing the front
wheel, and replace the defective rear
wheel with the front wheel.

5. When replacing the wheelscrews, do not
tighten too hard yet, and make sure that

the round surfaces of the screws sit pro-

perly in the depressions in the wheel,

which should be clean.

6. Screw the compressor hose first onto the

tyre valve, then plug the compressor into
the cigarette lighter socket. The neces­sary tyre pressure is reached in a few

minutes.

7. Check tyre pressure with pressure gauge.

8. Let the car down from the jack, and
remove jack. Tighten the wheelscrews.

1. Loosen front wheelscrews slightly.

2. Insert the car jack, with it tilted slightly
away from the bodywork, in the respec-

tive jacking point (black arrow).

72

3. Jack the car up until the wheel to be
changed is clear of the ground.

4. Remove wheelscrews, remove wheel and
mount the spare wheel on the front axle.

After changing a wheel, the wheelscrew
torque must be checked with a torque
wrench as soon as possible. (Tightening
torque 130 Nm, 13 kpm.)

Lifting the vehicle with it's own

jack

Lifting the vehicle

with a lifting platform or trolley jack

The jack may only be used at this point.

Warning: The jack is only provided to lift the

vehicle. If work is to be carried out under the
vehicle, the vehicle must be supported on
suitable chassis stands or similar.

Before driving over the lifting platform,
ensure that there is enough clearance bet­ween the underneath of the vehicle and the

lifting platform.

The car may only be lifted from the points

shown in the pictures.

Front: The normal jacking point.

Rear: Bearing bracket for back axle control

arms.

A trolley jack may only be used at the same
4 points as for the lifting platform, and also
under the middle of the back axle. To avoid
damaging these lifting points, a wooden
block or a rubber pad should always be
inserted between the vehicle and the jack.

The vehicle should never, under any cir­cumstances be jacked up from under the oil
sump or the gearbox, as this could cause
severe damage.

73

Changing a fuse

Relay function

Fuses and relays

To avoid short circuit or overloading damage
to the electrical cables or apparatus, the
individual circuits are protected by fuses.

The main fuse box is mounted in the passen-

ger footwell under the floor panel. To change
a fuse or relay, the carpet must be folded
back, and the floor panel hinged upwards. If
a considerable amount of work is necessary
on the fuse box, the battery earth cable
should be disconnected.

Switch off the affected system.

A blown fuse is evident from the burnt
through wire. To replace the fuse, it must be
pulled out of the clips. The fuse should only
be replaced with a fuse of the same rating.

Fit the new fuse with the wire visible. When
fitting, avoid touching the wire or bending
the clips that hold the fuse. The fuse must sit
firmly in the clips.

Warning: Never repair a fuse with wire or
silver foil as serious damage could result.
Should a fuse blow several times, an author­ised workshop should be consulted.

At the top edge of the fuse box is space for
spare fuses. It is advisable to carry spare
fuses of the different ratings in the vehicle.
Fitted underneath the fuses are relays for
various electrical switching functions.
Changing of defect relays should be left to
an authorised workshop.

Battery check and care

Checking the acid level

Because of the danger of short circuiting,
the battery should always be disconnected

before starting any work on the electrical
system. Disconnect the battery earth strap
as shown by the arrow in the picture.

Disconnecting the battery whilst the

engine is running destroys the alternator.
This applies also to vehicles with a built in
battery disconnection switch.

Remember that only a well charged battery

can deliver the necessary energy to start the
engine. The condition of the battery should
therefore be checked regularly. The battery

is located in the back of the vehicle, and is

reached via a flap in the spare wheel well.

Before the battery is to be charged with a
heavy duty charger, it must be disconnec­ted, or otherwise the alternator can be de­stroyed.

The battery capacity is reduced by lower
temperatures. However, during the winter
months, the demands made upon the bat­tery increase because of the need for more
lighting, heating fan, windscreen wipers etc.
Therefore check, especially when only mak­ing short journeys, that all unnecessary elec­trical systems are turned off.

With the vehicle standing level, remove all
the battery stoppers, and check that the
acid level in every cell reaches the full mark.
If the battery has to be topped up, use only
distilled water, not acid. During the summer
months, and in warmer climates, the battery
level should be checked more often.

Checking the specific gravity of the acid

In a battery in good condition, the state of
charge of the battery can be determined by
the specific gravity of the acid, which is mea­sured in Kg/dm3, determined with the use of a
hydrometer.

Checking the voltage of the battery

The voltage of a battery can only be measured
with a special instrument, and should there­fore be left to an authorized workshop.

Care of the battery

The battery poles must be kept clean. They
should be smeared with a suitable grease,
and check that the battery terminals are pro­perly fitted.

Check that the battery stoppers are seated
correctly, and that the vent holes in them are
not blocked.

Never let any acid come into contact with
clothing, or any parts of the vehicle. Should

battery acid be splashed or spilled, it should
be immediately neutralised with a soda solu-

tion.

Due to the explosive gases given off by a
battery, never go near it with a naked flame

or fire.

A battery loses it's charge when not being

used, so if the vehicle is laid up for any
period, the battery should be charged ap-

prox. every 6 weeks, to keep it in good con­dition. A battery left discharged for a length
of time will be ruined. Check, and if neces­sary top up the acid level, every time the bat­tery is charged.

76

Renewing bulbs

To avoid short circuits when changing bulbs,
the respective circuit should be turned off.

Bulbs should be clean and grease free,

therefore never touch the glass with your

bare hands, always use a cloth or a soft

piece of paper.

For safety reasons, you should always carry
spare bulbs in the vehicle, so that any bulb
can be immediately renewed when it blows.

Remember when travelling abroad, that in
some countries it is compulsory to carry
spare bulbs with you.

Only use soapy water to clean plastic light
lenses, never a chemical detergent.

Adjusting screws

Your Porsche is fitted with a headlight beam
adjustment device inside the vehicle, so that
optimum headlight illumination can be
obtained irrespective of the loading of the
vehicle, and without dazzling oncoming dri­vers.
The basic adjustment of the headlights can
only be performed on a special machine.
This should be carried out on the vehicle in a
ready to drive condition, and a full fuel tank.
The driver's seat must be loaded with a 75 kg
weight, or with a person, and the tires must

82

be inflated to the manufacturers specifi­cations. With the vehicle in this condition, it
must be rolled several meters to allow the
road springs to settle, before starting to
adjust the lights.
The adjuster knob for the interior headlight
setting must be in the neutral position, i.e.
the white mark on the knob directly over the
mark "O" on the rosette (see headlight
beam regulator). To adjust the headlights,
the screws must be removed from the head­light housings, and the housings removed.

Each headlight has two adjusting screws,
one for lateral setting, and one for vertical.

By turning these screws left or right, the cor­responding adjustment in beam position is

effected.

Adjustment of auxiliary driving lamps

The auxiliary driving lamps are adjusted
such, that the centre of the light beam is the
same height as the centre of the lamp.

If your vehicle is equipped with asymmetric­al dipped beam headlights, and you travel
abroad, where the traffic drives on the other
side of the road, you should stop at the bord­er, and blank off the prism section of the
light diffusing lens with opaque adhesive
strip. The dipped beams will then be sym­metrical, and will not dazzle oncoming dri­vers.

Manual operation of the headlights

If, by reason of a malfunction in the headlight
elevating motor, the headlights cannot be
raised or lowered, the knob on the driveshaft
of the elevating motor can be manually turn­ed, to raise or lower the headlights. The
elevating system is so designed that, to
raise or lower the headlights, only one turn
to the left with the knob is necessary.

Do not try to turn the elevating motor knob
when the headlights are functioning nor­mally from the light switch as they should,
because of the danger of being injured.

By virtue of the switching principle, the ele-

vating motor drives the elevating mechan-

ism another half a turn (180°) that is to say
that after several turns of the knob a contact
is closed so that when the headlights are
functioning normally, they go up and come
down immediately.

83

Towing

Remember, when the engine is not running,

that no servo assistance is given, and more

power is required by braking and steering.

For towing vehicles fitted with automatic
transmission please adhere to the regula­tions to be found in the sections "Automa­tic Transmission".

The towing eye is located in the tooltray in
the rear of the car.

To tow another vehicle, the towing eye must
be screwed into the hole in the rear bumper
above the rear number plate. Always screw
the towing eye right in.

Should it be necessary for your Porsche to be
towed, the towing eye must be screwed into
the right hole beside the cooling radiator, at
the front of the car. The plastic stopper must
first be removed.

84

Always take into account the necessary
laws governing towing.

When you tow another vehicle, it must not
be heavier than your Porsche.

During towing, always keep the towrope
taut, but avoid sudden jerks on the rope. The
vehicle being towed should have the ignition
turned on so that the brake and direction
indicator lights function, and that the steer­ing lock is released.

Tow-starting

Vehicles with automatic transmission cannot
be tow-started. If the battery is faulty or com­pletely flat, the engine can only be started after
replacing the battery or by using jump leads.

If your vehicle is tow- or roll-started the cen­tral warning light and the individual warning
lights can only be turned off by switching the
engine off and restarting it with the ignition key
(see also "Warning Unit").

2. Only battery cables with adequate dia­meters should be used. Observe manu­facturers specifications.

3. A discharged battery can freeze at -10°C.
A frozen battery must be thawed out
before connecting the battery cables.

4. There should be no contact between the
two vehicles otherwise current may flow
when the positive pole is connected.

5. The discharged battery must be correctly
connected to the vehicle electrical sys­tem.

6. Run the engine of the vehicle supplying

the current.

Care should be taken that the cables do

not make contact with each other and that

the positive cable does not come into

contact with other electrical terminals -

danger of short circuit!

8. Start engine as described in the section
"Starting the engine".

9. When the engine is running disconnect
the cables in the reverse order.

Emergency Starting

Should the engine not start because the bat­tery is flat e. g. in winter or after the vehicle
has stood for a long period, the battery from
another vehicle can be used with the aid of
an auxiliary battery cable. The following
points should be observed:

1. Both batteries must be 12 volt. The cap­acity (Ah) of the battery supplying current
should not be significantly below that of
the discharged battery.

7. Connect the auxiliary battery leads in the

following order:

First fix one end of the (+) lead to the (+)
clamp on the right at the front of the en-

gine compartment (arrowed). Then con-

nect the other end of the lead to the (+)

terminal of the feed battery.

Now clamp one end of the (-) lead to the
(-) terminal of the feed battery, then at­tach the other end to the cylinder block
or the transverse strut in the engine com­partment (arrowed).

Motor Oils

Use only branded HD oils which satisfy the
API classification API SE or SF for gasoline
engines. These classifications are often given
together with the classifications for diesel en­gines, e. g., SE/CC, SF/CC or SF/CD.

Single-grade, multigrade and fuel-economy
oils can be mixed provided the viscosity grades
correspond to outdoor temperatures.

Single-Grade Oils

Single-grade oils may only be used when
multigrade oils are not available and the car is
being used under normal conditions. To pre­vent damage, the oil must be changed as re­quired when temperatures change consider­ably.

Multigrade Oils

The oil change intervals given in the service
schedule apply when multigrade oils are used.
For all-season use only the multigrade oils
indicated the table opposite may be used, in
accordance with prevailing air temperatures.

Fuel-economy Oils

In addition to single-grade and multigrade oils,
"fuel-economy" oils are available (developed
for all-year round use). Before using these
unconventional oils, consult your authorized
Porsche dealer.
