Dear Porsche Owner Before going on a trip...
A lot has gone into the manufacture of your Porsche, including advanced engineering
techniques, rigid quality control and
demanding inspections. These engineering
and safety features will be enhanced by
you... the safe driver...
who knows his car and all controls who maintains his vehicle properly who uses his driving skills wisely, and who always drives within his own capabilities and
his level of familiarity with his vehicle.
You will find helpful hints in this manual on
how to perform most of the checks listed on
these pages. If in doubt, have these checks
performed by your Porsche dealer.
First things first
Turn the engine off before you attempt any
checks or repairs of the vehicle.
Be sure tires are inflated correctly. Check for
damage and tire wear.
See that wheel bolts are properly tightened
and not loose or missing.
Check engine oil level, add if necessary.
Make it a habit to have engine oil checked
with every fuel filling. Check coolant level to assure sufficient
engine cooling.
Be sure you have a well charged battery. Check brake fluid level. If too low, have
brake system checked.
Replenish windshield washer fluid. Check if engine hood is latched safely. Replace worn or cracked wiper blades. See that all windows are clear and
unobstructed.
Keep air intake slots and area between engine hood and windshield free of snow and ice, so that the heater and the windshield wipers work properly.
Check whether all light lenses are clean.
Be sure all lights are working and headlights
are aimed correctly.
Check under vehicle for leaks. Be sure all luggage is stowed securely.
Emergency equipment 3
It is good practice to carry emergency
equipment in your vehicle. Some of the things
you should have are: window scraper, snow
brush, container or bag of sand or salt,
emergency light, small shovel, first-
aid kit, etc.

8

In the driver's seat... On the road...
Check operation of horn.
Position seat for easy reach of controls. Adjust inside and outside rear view mirrors. Attach your safety belts. Check operation of foot and parking brakes. Check all warning and indicator lights when
starting the engine.
NEVER leave car idling unattended. Lock doors from inside, especially with
children in the car.
To prevent inadvertent opening of doors
from inside or outside, drive with locked
doors.

Never drive after you have consumed
alcohol.
Always have your safety belt attached. Always drive defensively. Expect the unexpected. Use signals to indicate turns and lane
changes.
Turn on headlights at dusk. Always keep a safe distance from the vehicle in front of you, depending on traffic, road and weather conditions. Reduce speed at night and during inclement weather.
Driving in wet weather requires caution and
reduced speeds, particularly on roads with
standing water, as the handling characteristics of the vehicle may be impaired due to tire
aquaplaning.
Also, when crossing stretches of deeper water there is a danger that too high of a speed can
cause water to enter the engine combustion
chambers through the intake air system
and/or water may strike the cooling fan
causing cooling system damage. In order to
avoid possible en- gine or cooling system damage when driving
through deep water, the vehicle should be
driven at a walking speed in first gear.
Observe speed limits and obey road signs.
When tired, get well off the road, stop and
take a rest. Turn the engine off. Do not sit in
the vehicle with engine idling. See
WARNINGS on "Engine Exhaust".
When parked, always set the parking brake.
Move the selector lever to "P" (Automatic
transmission) or move the gearshift lever to
reverse or first gear (Manual transmission).
On hills also turn the wheels toward the curb.
When emergency repairs become necessary, move the vehicle well off the road. Turn on
emergency flasher and use other warning
devices to alert other motorists. Do not park
or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel spill or other flammable
material.
Make it a habit to have the engine oil
checked with every fuel filling.
9

NEVER invite car theft! An unlocked car with the key in the ignition switch invites car theft. A steering wheel lock and a buzzer alarm are standard equipment in your Porsche. The
buzzer will sound if you open the driver's door
while the key is still in the ignition lock. It is your reminder to pull the key out of the ignition lock and to lock the doors.



Always remove the ignition key, especially
if children are left unattended in the
vehicle. Unsupervised use of any vehicle
key may cause serious personal injury.
NEVER leave your vehicle unattended with
the key in the ignition lock. Take the key
and lock the doors.

Keys
The vehicle is supplied with three keys fitting
all locks. All keys are symmetrical so that
there is no wrong way of inserting them in the
locks. Two keys (a) are fitted with a battery
light which is integrated in the plastic handle
and lights up upon pressing the contact
button. The third key (b) is flat and should be
kept as an "emergency key", for instance, in
your purse.
After pulling the plastic head off the flat key, you can snap on a luminous plastic handle
available from your Porsche dealer.
WARNING NEVER remove the key from the steering
lock while you are driving or as the car is
rolling to a stop. The steering column will
lock when you remove the key, and you
will not be able to steer the car.

When the key bulb becomes weak, you
should install a new battery of the same
voltage. Acid leaking from a discharged
battery might damage your clothing.
1.
Use your finger nail or a small screw driver
to carefully lift the key handle cover.
2.
Insert a new commercial battery (1.5 V) in
the contact button.
3.
Assemble key top as shown in the above figure.
10

Key number
The key number is impressed on a plastic tag
(d) which comes with the keys. Detach this tag and keep it in a safe place. The key numbers
of the other keys are embossed on the key
heads.
For your protection against theft:
Record the key number and keep it in a safe
place, such as your wallet. Do not keep it in
the vehicle.
If you should lose a key, provide your Porsche dealer with the key number to obtain a duplicate key.
For the lockable wheel nuts, three identical
keys (c), plus four wheel nuts with lock slee
ve, are included. When taking the vehicle to your
Porsche dealer or to a workshop for wheel or
tire service, remember to leave one key with
the service attendant.
In case of loss, duplicate keys cannot be
furnished by your Porsche dealer. Do not
leave these keys in the vehicle. Keep them in
a safe place.
See "Lockable wheel nuts" for details.




Anti-theft alarm
If your Porsche is equipped with an antitheft
alarm system, you will be given an additional
set of duplicate keys. Keep one of these keys
in a safe place but not in the car.
The alarm system can be activated or
deactivated with this key only.
The lock for the anti-theft alarm system is
located behind the door lock on the driver's
side.
To activate the alarm system, insert the key
and turn the lock slot 90° to the right.
To deactivate the alarm system, insert the
key and turn the lock slot 90° to the left.
When the alarm system is activated, and an
attempt is made to open either door, or to lift
the engine hood or the rear hatch, the alarm
will be triggered and will produce an intermittent high-pitched noise for about 30
seconds.
Should an attempt be made to start the
engine, the alarm will also be set off.
However, when the alarm system is activated, it is impossible to start the engine.
11

Doors To lock, unlock and open doors from the
outside
All doors can be locked with the ignition key.
The passenger door can be locked without a
key by first depressing the locking knob and
then closing the door.
The driver's door can only be locked from the outside with the key. This precaution was
taken to prevent locking the driver's door
while the key is still inside the car. Squeeze trigger in door handle to open door.
To lock, unlock and open doors from the inside
Lock or unlock door by depressing or raising
the locking knob.
Open door by pulling inside door handle
located above the armrest.

Power Windows
To open or close windows, depress the
rocker switches located in the door panels. The door window on the passenger's side can also be operated from the drivers side.
The power windows are operational when the
ignition switch is turned to positions 1 or 2.
Information regarding ignition switch posi- tions will be found in section titled,
"Ignition/starter switch with steering lock".
When the ignition is turned off or the ignition
key removed, the power windows can be
operated until one door is opened.
WARNING

Do not put anything on or near the windows that may interfere with the
driver's vision.
Remove the ignition key to shut off power to the window switches when the vehicle
is not attended by a responsible person.
Remember, power is still supplied to the
window switches until one door is opened. 12



Central Locking

By means of the central locking system both
doors are electrically locked or unlocked
(locking button lowered or raised) when a door lock is turned with the key. Before locking,
make sure that both doors are properly
closed.
When the doors are locked, the removable
roof is also locked at the same time.
If the roof is open, it is not affected by the
central locking system.
Both doors can be individually locked from
inside by pressing the locking button. If the
locking button is used to unlock one door, the
second door is also automatically unlocked.

To prevent you from locking yourself out of
the vehicle, it is not possible with the driver's
door open to lock the door lock with the
locking button.
Emergency operation


Should the central locking fail, both doors can
be opened and closed mechanically. Central Locking Switch


By pressing the central locking switch (A) in
the centre console it is possible with the
ignition key in position 2 to lock or unlock both doors electrically. As a check, if the doors are
locked, a red indicator lamp in the switch
lights up.
If one of the doors has been locked manually,
the red indicator lamp lights up. By pressing
the switch, the door is unlocked; when
pressed again, both doors are locked.
With the ignition key removed, locking is
possible by means of the central locking
switch. To unlock, the ignition must be
switched on or the locking button raised. 13

Safety belt warning system

An audio-visual warning system is
interconnected with the driver's safety belt.
Every time the ignition is turned on, the seat
belt warning light in the left instrument cluster
comes on for about 6 seconds to remind driver and passenger to buckle up. If the driver does
not fasten the safety belt, the buzzer will
continue for the duration of this six second
period. The buzzer will go off as soon as the
driver has buckled up.
Inertia reel retractor


The combination lap/shoulder belt with inertia
reel locking mechanism adjusts automatically
to your size and movements as long as the
pull on the belt is slow.
Rapid deceleration during hard braking or a
collision locks the belt. The belt will also lock
when you drive up or down a steep hill or in a sharp curve. Otherwise the shoulder belt will
not inhibit your upper body movement.

To fasten, grasp belt and pull belt in
continuous slow motion across your chest
and lap.
Insert belt tongue into buckle on inboard side of seat. Push down until it securely locks with an audible click. Pull belt to check. Pull shoulder section to make sure belt fits
snugly across the hips.
Belts should fit snugly across the pelvis and
chest. Make sure any slack is wound on the
retractor.

18






To unfasten belt, push in release button on
buckle. Belt tongue will spring out of buckle.
To release a locked belt, lean back to take
the body pressure off the belt.
To store lap/shoulder belt, allow belt to wind
up on retractor as you guide belt to its
stowed position on doorpost.

Lap belts for rear seats


The lap belt with inertia reel locking
mechanism adjusts automatically to your size
and movements as long as the pull on the belt is slow.
Rapid deceleration during hard braking or a
collision locks the belt. The belt will also lock
when you drive up or down a steep hill or in a
sharp curve.
To fasten lap belt, grasp belt on outboard
side of seat and slowly pull across the pelvis.
Insert belt tongue into buckle on inboard side
of seat and push down until it securely locks
with an audible click. Pull belt to check.

To unfasten belt, push in release button on
the buckle.
To store belt, allow belt to wind up as you
guide belt to retractor.
19

Rear View Mirrors

Do not put decals or other signs on the
windows that may interfere with the driver's
vision.
Adjust the outside and inside mirrors before driving. It is important for safe driving that you have good vision to the rear.
Inside day-night mirror

You can adjust the day-
night mirror from clear daylight visibility to non-glare visibility at night by moving the lever at the bottom of the
mirror forward or rearward.
Heated outside mirrors with remote
control


When you turn on the rear window defogger,
the outside rear view mirror is also heated.
The outside mirrors are ad
justable from inside of the vehicle by a four direction switch
located on the left door and a rocker switch
located on the center console ahead of the
gear selection lever. The rocker switch (A)
selects either the left or right mirror for
adjustment. Push
the rocker switch forward to select the left mirror, and rearward to select
the right mirror. Then the four direction switch
will adjust the selected mirror in any of the four directions.

The steering is blocked by the steering lock: all circuits wired through the ignition
are switched off.
The ignition key can only be withdrawn in the
"0" position. The parking lights can be
operated in this position by pushing the turn
signal indicator lever up and down (also see
"Parking lights").
1 Position for radio. Steering unlocked. If it is difficult to turn the key, gently move the
steering wheel until the key turns freely.
Note: all circuits which are disconnected in
position "3" can be switched on.
To conserve battery power, switch off other
electrical consumers while playing radio in
position "1".
2
Ignition on. All electric circuits are
operational. With the engine stationary, the
central warning light and all individual
warning lights located in both combination
instruments will light up for a bulb check.
3
The starter is operated by turning the
ignition key to the right. As soon as the
engine starts, release the key. It will spring
back to position "2". With the engine
running, the central and individual warning
lights should go out (see "Central warning
light").
To conserve battery power, the electric
circuits for headlights, rear window de-
fogger/defroster, temperature control and
wiper/washer system are temporarily interrupted during the starting process.
The starter should not be operated for more
than 10 to 15 seconds at a time. If the engine
does not start the first time or stalls at any
time, the ignition key must be returned to the
"0" position. The non-repeat lock in the switch
prevents the
starter from being operated when the engine is running and guards against
starter damage.
To remove the key and to lock the steering
wheel
, turn the key back to position "0" and
pull out. Turn the steering wheel until it locks.

WARNING
Never remove key from ignition lock or
turn key off while vehicle is moving. The
steering wheel will lock, causing loss of
control.
Instrument panel lights
Warning lights for alternator, oil pressure, and
brake system will light up for a bulb check
when the ignition is turned on. They should go out after the engine is started. The brake
warning light will go out after the parking
brake has been fully released. See
"Warning lights" for more details.
Buzzer
If you leave the key in the ignition/steering
lock, the buzzer will sound when the driver's
door is opened. This is a reminder to remove
the key.
For further details see "Starting Procedures"
on the following page.

24

Starting Procedures

WARNING
Fasten safety belts before driving.
Never start or let the engine run in an enclosed, unventilated area. Exhaust
fumes from the engine contain carbon
monoxide, which is a colorless and
odorless gas. Carbon monoxide can be
fatal if inhaled.

Never leave engine idling unattended. An unattended vehicle with a running engine
is potentially hazardous.
Do not park or operate the vehicle in areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other flammable material.
Never leave engine idling. When starting engine, be ready to drive immediately.
Maintain moderate speed until engine is
warm.

Automatic Transmission - Start with selec-
tor lever in Park.
Manual Transmission - Start with gearshift
lever in Neutral.
Temperature sensors on the engine auto- matically provide the correct fuel/air mixture
required for starting.
Therefore, do not depress the accelerator
pedal while starting a cold or a warm engine.
When starting at very low outside
temperatures , fully depress the clutch pedal,
so that the starter only has to crank the
engine.
As soon as the engine starts, release the ignition key.
If the engine fails to start after 10 to 15
seconds of cranking, wait about 10
seconds before engaging starter again.
Do not let engine idle to warm it up. After
starting, drive vehicle at moderate speeds and with gradual accelerations. Avoid high rpm
and full throttle operation until the engine has
reached normal operating temperature.
Stopping engine
Turn key back to position 0.
Do not stop engine immediately after hard
or extended driving. Keep engine running
at increased idle for about two minutes to
prevent excessive heat buildup before
turning off engine.
WARNING
Before you check anything in the engine compartment, let the engine cool down.
Hot components can burn skin on
contact.

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

If you have an automatic garage door...
The transistorized ignition system in your
Porsche may interfere with your electronically
operated garage door. To check this: drive
your Porsche close to the garage door and
run the engine at different speeds.
If the garage door opens or closes without
your operating the garage door unit in your
car, contact the dealer who installed the
automatic garage door to have the frequency
and/or coding of the garage door signal
modified.
25

Windshield Wiper/Washer Lever
(with intermittent wiper operation)
The windshield wiper/washer switch has se-
ven positions:
1 - Low speed
2 - Normal speed
3 - High speed
4 - Intermittent wiper operation
5 - Windshield washers
6 - Windshield washers and wipers
7 - Headlight washers
The time intervals can be set at the control
element to the right of the ignition lock.
Pulling the lever from its basic position
towards the steering wheel activates the
windshield washer pump in the first stage
(switch position 5) and the windshield wipers
in the second stage (switch position 6).
The electric windshield washer system can be operated by pulling the lever toward the
steering wheel from any wiper position.
When the ignition is switched on, the washer
nozzles are heated, depending on the outdoor temperature. Nevertheless, a commercial windshield anti-freeze solution should be
added to the windshield washer water during
cold weather conditions.
Avoid running the wiper blades over a dry
windshield to p
revent scratching the glass. Spray on washer fluid first. A scratched
windshield will reduce visibility.
Always loosen blades frozen to glass
before operating wipers to prevent damage to wiper motor.
WARNING
Worn or dirty wiper blades will reduce
visibility, making driving hazardous. Clean
blades regularly to remove road film and
carwash wax buildup. Use an alcohol base
cleaning solution, a lint free cloth and wipe lengthwise.
Clean all inside and outside window glass
regularly. In vehicles without Securiflex
windshields use an alcohol base cleaning
solution and wipe dry with a lint free or a
chamois cloth.

In vehicles with Sekuriflex windshields, the plastic coating on the inside of the
windshield must not have gummed labels
put on it or be cleaned using aggressive
