tow PORSCHE 944 1987 1.G Owners Manual

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.

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.

Emergency Adjustment

In the event of a failure of the electrically
operated seat adjuster, fore-and-aft
adjustment of the seat can be obtained using
the Allan key contained in the tool kit. The seat is adjusted by turning the servo motor located
at the front on the seat using the Allan key.
Backrest Lock


The backrest is locked to prevent it from tilting forward when you are forced to brake hard.
For unlocking, pull up the knob on the left or
right side of the backrest.
WARNING
For driver and passenger protection, back-
rest locks must be engaged at all times
while the vehicle is in motion.

16

Safety Belts

WARNING
For your and your passengers' protection, use safety belts at all times
while the vehicle is in motion. Use child
safety seats for all small children. Safety belts must be properly positioned on the body. Improperly positioned safety belts may cause serious personal injury
in case of an accident. Therefore heed all
of the following warnings and
instructions.
A combination lap-shoulder belt should not be worn by a person less than 4'11"
or 1.5 m in height, because it would not
be in its most protective position and
therefore may increase the possibility of
injury in an accident.
Persons smaller than 4'11" or 1.5 m in height, and children who are able to sit
upright by themselves, should use one of the rear seating positions and the lap belt provided. For maximum safety and protection, we recommend that small children travel in
the rear seats. Regardless of where small
children sit, remember that every state in
the US now requires small children to
ride in child safety seats. When driving in some states and many foreign countries, remember that they
require the wearing of safety belts by law.

Do not strap in more than one person with each belt. For maximum effectiveness, the lap belt should be worn low across the pelvic
crest.
Do not wear shoulder part of belt under your arm or otherwise out of position. This would increase the possibility of serious
injury in case of an accident.
Belts should not be worn twisted. Do not wear belts over rigid or breakable objects in or on your clothing, such as eye glasses, pens, keys, etc. as these may
cause injury.
Several layers of heavy clothing may interfere with proper positioning of belts. Belts must not rub against sharp objects. Keep belt buckles free of any obstruction that may prevent secure locking. Make sure that belt of the unoccupied passenger seat is fully wound up on its
retractor so that the belt tongue is in its
stowed position. This reduces the
possibility of the tongue hitting a vehicle
occupant in case of sudden stop.
Belts that have been subjected to excessive stretch forces in an accident
must be replaced.
If belts show damage to webbing, bindings, buckles or retractors, they
should be replaced.


If belts do not work properly, see your authorized Porsche dealer. Do not modify or disassemble the safety belts in your vehicle. The belts must be kept clean as otherwise the retractors may not work properly (see
also "Car care instructions").
Never bleach or dye safety belts. Do not allow safety belts to retract until they are completely dry.
17

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

The brake warning light on the dashboard will go out after the engine is started and the
parking brake is fully released.
WARNING
Release the parking brake fully. A partially engaged brake will overheat the rear
brakes, reduce their effectiveness and
cause excessive wear.
Always set the parking brake when parking your car. Move the selector lever
to "P" (Automatic transmission) or move
the gearshift lever to reverse or first gear
(Manual transmission). On hills also turn
the wheels toward the curb.

WARNING Failure of one brake circuit will impair the
braking capability resulting in an
increased stopping distance.
If one brake circuit has failed, the other will
still operate. However, you will notice an
increased pedal travel when you step on the
brake. Should you encounter such
experience, bring your vehicle safely to a full
stop.
Avoid driving the vehicle and instead have it towed to the nearest authorized Porsche
dealer.

Brake Pedal

Parking Brake Lever
Parking brake force is mechanically trans-
ferred to the rear wheels by means of cables.
Use the parking brake only after the vehicle
has come to a full stop.
To set parking brake,
pull the lever all the way up (arrow). With the ignition on, the brake warning light will come
on.
To release the parking brake,
pull the lever slightly up as you depress the
release button, and then push the lever all
the way down.

Brakes

Functioning of brake system
Your Porsche is equipped with a power
assisted hydraulic dual circuit brake system
with disc brakes at the front and at the rear. Both circuits function independently. One
brake circuit operates the front and the other
the rear axle.
In the unlikely event of hydraulic failure of
one circuit, push the brake pedal down
firmly and hold it in that position. A
mechanical linkage activates the second
circuit, and you will be able to bring the
vehicle to a stop.
WARNING
The movement of the brake pedal must never be obstructed by a floor mat or any
other object. In case one of the two brake
circuits fails, increased pedal travel is
required to bring your vehicle to a full
stop.

Make sure that the size of your floor mat does not hamper the movements of either brake, clutch or accelerator pedals in any
way.
Secure the floor mat against sliding into positions that could interfere with the
safe operation of your vehicle.
Do not "ride the brakes" by resting your foot on the pedal when not intending to
brake. Overheating and premature wear
of the brakes will result.
26

Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or driving position to control speed. Do
not ride the brakes or hold pedal down too
long or too often. This could cause the
brakes to get hot and not function properly.

Brake operation and brake warning light
Make it a habit to check the operation of your
brakes before driving. The failure of a brake
circuit is indicated by the lighting up of the
dual-circuit brake indicator lamp. See also
brake fluid warning lamp.
With correctly adjusted brakes the pedal travel to the point of brake actuation should be
13/16" to 19/16" (30 to 40 mm). Whenever the brake pedal travel is greater, have the brake
system checked.
Keep in mind that the braking distance
increases very rapidly as the speed increases. At 60 mph/100 km/h, for example, it is not twice but four times longer than at 30 mph/ 50
km/h. Tire traction is also less effective when
the roads are wet and slippery. Therefore,
keep a safe distance from the car in front of
you.

Brake Booster The brake booster assists braking only
when the engine is running. When the car is moving while the engine is not running, or if
the brake booster is defective, more pressure
on the brake pedal is required to bring the car
to a halt.
Moisture or road salt on brakes affects
braking
WARNING
Driving through water may reduce tire
traction. Moisture on brakes from road
water, car wash, or coating of road salt
may affect braking efficiency. Cautiously
apply brakes to test them after being
exposed to such conditions. When the
vehicle is driven on salted roads for
extended periods, the brakes should be
hosed down thoroughly about every 2
weeks. An automatic car-wash facility
cannot do this job properly. Brakes will dry after a few cautious brake applications.
Brake wear
Our automobiles have excellent brakes, but
they are still subject to wear, depending on
how the brakes are used. Have the brake
system inspected at the intervals
recommended in your Warranty &
Maintenance booklet.

New brake pads or linings Brake pads or
linings may not have the highest possible
braking efficiency when new. Therefore allow
for longer braking distance during the initial
100 to 150 miles or 150 to 250 kilometers of
normal city driving; longer if fewer stops are
realized.
Clutch Pedal
Due to the hydraulic operation of the clutch,
pedal play should be 0.1" or 2.5 mm.
To check the play, depress the clutch pedal.
Excessive play or tightness indicate a
malfunction of the clutch. Both conditions can
lead to severe damage. Contact your Po
rsche dealer promptly to have the cause located and corrected. Always depress the clutch pedal fully when changing gears. Do not hold the car on a
steep hill with the clutch pedal partially
depressed. This will cause premature wear or
damage.

27

ABS Brake System (Antilock brake system)
The ABS system represents a major
contribution to the enhancement of active
safety in your vehicle. This system prevents
the wheels from locking in a panic stop on
almost all road surfaces.
With ABS system in your vehicle, the
following areas are enhanced:
Full steerability , vehicle remains steerable
under all braking forces.
Good directional control , no swerving
caused by locking of wheels under braking
conditions.
Excellent stopping distance , stopping
distances are usually reduced because
controlled braking is maximized.
Prevention of wheel lock up , no brake-
induced sliding and thus no localized tire wear from emergency braking.
The crucial advantage of ABS system over a
conventional brake system is in the area of
maintaining directional control and
maneuverability of the car in emergency
situations, including panic braking in turns.
WARNING:
In spite of the improved handling afforded
by the ABS system, it still remains the
responsibility of the driver to adapt the
driving style to the prevailing road and
weather conditions, as well as, obeying
traffic laws. In no case, should the higher
degree of safety offered by ABS be
regarded as a

justification for taking greater risks. Other vehicles not equipped with the ABS
system may not be able to maintain
control, especially on wet or poor road
surfaces and thus may be more likely to
impact you in the rear. To minimize that r
isk, use your ABS system to increase your ability to maneuver to avoid dangerous
situations and not merely to try to stop in
the shortest distance possible.
Driving with the ABS System
A wheel speed sensor is fitted to each of the four wheels. If wheel slippage of either of the
front wheels or the rear wheels is sensed
during braking, the brake pressure is adjusted
automatically until the wheel no longer slips.
The brake pressure is regulated for each front
wheel individually and for both rear wheels together.
On a road surface which is slippery on only
one side, the rear wheel which is braking on
the slippery surface determines the brake
pressure which will be applied equally to both
rear wheels. This ensures that directional
stability is maintained. However, if braking
force approaches the wheel locking-up point
for all wheels (panic braking) the ABS system
will intervene in a way comparable with rapid rhythmic braking. The proper operation of ABS is perceived by the driver as a pulsating brake pedal in conjunction with audible noise
and perhaps some vibration. The driver is
thereby warned to reduce vehicle speed
appropriate for the prevailing road conditions.

If your ABS system should ever malfunction,
the ABS system is automatically switched off,
but the normal brake system, without ABS,
would remain fully operational. Such a malfunction would be indicated by the illumination of the central warning light, as well as the "ANTILOCK" light on the right hand
side of the instrument cluster.
If the ABS system becomes inoperative,
take your vehicle to your authorized dealer immediately.
Note
The control unit of the ABS brake system is
set for standard tire sizes. If non-standard
tires are fitted, the control unit may
misinterpret the speed of the vehicle, because of the variant data it receives from the sensors on the axles.
If the difference in rolling radius exceeds
approx. 17%, the control unit deactivates the
ABS system and the ABS warning lamp lights up.

Automatic Speed Control
The automatic speed control allows you to
maintain a constant cruising speed of 25 mph
(40 km/h) or higher, without actuating the
accelerator pedal. Any manual operation,
such as accelerating, gearshifting or braking
can be done independent of the automatic
speed control. The spring loaded control lever
operating the automatic speed control is
located just below the wiper/ washer lever.
While driving with the automatic speed
control set at speeds above 25 mph (40
km/ h), do not bring shift lever into the
Neutral position as excessive engine rpm
will result.
To operate the automatic speed control Accelerate to the desired cruising speed, push lever toward instrument cluster (arrow 1) and
release. This sets the cruising speed and
stores it in a memory.
After a second or two, automatic speed control will take over and you can remove
your foot from the accelerator pedal. The set
cruising speed will be maintained
automatically.
WARNING
Do not use the cruise control when it may
be unsafe to keep the car at a constant
speed. For example, a constant speed may not be safe in heavy traffic, or on winding
or slippery roads. With the cruise control
system engaged, the engine speed will not
return to idle when removing the foot from
the accelerator pedal.
Please observe all local and national speed limits.

Passing: If you want to drive faster for a brief
moment, for example when passing another
vehicle, actuate the accelerator. When you
take your foot off the accelerator pedal, the
preset speed will automatically be resumed.
Gearshifting: When shifting gears, the
automatic speed control is only disengag
ed as long as the clutch pedal is depressed. The
preset speed will be resumed as soon as you
take your foot off the clutch pedal.
Braking and stopping: Whenever you apply
the brake or come to a stop, the automatic
speed control is disengaged. Move the lever
down (arrow 2), and the preset speed will be
resumed.

Switching system off: To switch off the
automatic speed control, move the lever
toward you (arrow 3). To resume the preset
speed, move the lever down (arrow 2).
To change the preset cruising speed
Increase preset speed:
Accelerate by depressing the accelerator pedal. When the desired speed is reached push lever toward instrument cluster (arrow 1) and take your foot off the accelerator pedal.
Now the new cruising speed is set and stored
in the memory. As an alternative, you can hold the lever in the front position (arrow 1), without depressing the accelerator pedal. The car will
accelerate on its own. When the desired
speed is reached, release the lever.
Decrease preset speed:
Apply the brake, which will disengage the automatic speed control. When the vehicle
has slowed down to the desired speed, push
lever toward instrument cluster (arrow 1) to
set the new cruising speed.
As an alternative, disengage the automatic
speed control by moving the lever toward you
(arrow 3). When the vehicle has slowed down
to the desired speed, push lever toward
instrument cluster (arrow 1) to register the
new cruising speed in the memory.
Note: When driving up a hill, if the engine
power is insufficient in a particular gear, the
speed control will be disengaged
automatically. Shift to a lower gear to avoid
stalling the engine.

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
agents or dry methods. If very dirty, it can
be cleaned with benzine. Make certain that
the plastic coating is not damaged in
cleaning by hard objects such as jewelry
or wristwatches.

31

Right Instrument Cluster
The right instrument cluster combines the oil
pressure gauge with the oil pressure warning
light, the voltmeter with the alternator warning
light as well as the brake fluid warning light.

Oil Pressure Gauge
Engine oil pressure is shown in bars. At 5.000 rpm, with the engine at normal operating temperature (approx. 90°C / 194°F), the pressure should be approx. 4 bar. A slight
drop in oil pressure is normal under certain
operating conditions such as prolonged
highway driving in hot weather.
At idle speed, with the engine oil hot, the oil pressure can sink to 0.5 bar - this does not
indicate any loss of engine performance.
However, if the oil pressure drops suddenly
while you are driving, or if the warning light comes on, pull off the road,
stop the engine
and wait for it to cool down. Check the
engine oil level. If the oil level is normal,
contact the nearest dealer.

Oil Pressure
Warning Light
The oil pressure warning light comes on when the ignition is turned on. It should go out when the engine is started and has reached the
correct oil pressure.
If the oil pressure warning light
does not light up when turning the ignition on, or if it does
not go out after starting the engine, contact
your Porsche dealer immediately.
If the oil pressure warning light comes on
while you are driving, pull off the road and stop the engine .
Check the oil level to make sure you have
enough oil. If oil level is correct and the oil pressure warning light is still on, do not driv
e
the vehicle as severe engine damage may
result. Contact your nearest Porsche dealer
for assistance.
An occasional brief flickering of the oil pressure warning light at idle speed and
normal engine temperature is no cause for
concern if the light goes out upon
acceleration.
The oil pressure warning light is not an
indicator for low engine oil level. To check the
oil level, always use the dipstick.
Make it a habit to have the oil level checked
with every fuel filling.
Voltmeter
The voltmeter shows the overall condition of
the charging system. The needle should
normally stay in the 12-
14 volt range when the engine is running. A temporary drop below 12
volts when starting the engine is normal.
38

Alternator Warning Light
The alternator warning light comes on when
the ignition is turned on. It should go out after
the engine is started.
If the alternator warning light does not light
up when turning the ignition on, or if it does
not go out
after starting the engine, there is a malfunction in the electrical system. If this is
the case, contact your Porsche dealer.
WARNING
If the alternator warning light comes on
while you are driving, pull off the road and
stop the engine.
Check whether the Polyrib-belt is slipping or
broken. The Polyrib-belt not only drives the
alternator for battery charging, but also the air
conditioner compressor.
If the light just flickers lightly, the Polyrib bel t
may be loose and is slipping.
The belt should be tightened or replaced
before you continue driving.


Brake Fluid Warning
Light
The brake warning light monitors the hydraulic dual-circuit brake system. It lights up when the ignition is turned on and should go out after
the engine has been started.
If the brake warning light fails to light up when
the ignition is turned on, or if it fails to go out
after the engine is started, there may be a
malfunction in the electrical system. Let your
Porsche dealer locate and correct the
condition promptly.
Should the light come on while driving, the
brake fluid level in the reservoir could be too
low, or one of the dual brake circuits may
have failed. In either case, the brakes will
function but a much longer distance and a far
greater pedal pressure are required to bring
the car to a halt. See "Brakes" for more
details.
Carefully pull off the road and stop. Have
your car towed to the nearest dealer for
repair. Continued operation of a car with
defective brakes is dangerous.
Antilock
The warning light goes on in the event of a
malfunction in the ABS system. The system is
switched off; the normal brake system
remains fully operational. If the light comes
on, take your vehicle to your authorized dealer for service immediately.
Air Bag
See "Air Bag System" for details.

39

Rear Window Wiper
To operate the wiper, depress the rocker
switch (A) on the center console. The rear
window must be sufficiently wet to prevent the glass surface from being scratched.
Ashtray
The ashtray is in the center console. To empty the tray, pull it out of its well.
Reinsert it so that the light "window" points
toward the bulb on the back inside the well.
WARNING
Never use ashtray as waste paper
disposal. Fire hazard!
Glove Compartment
Press locking button to open glove
compartment. With the car lights turned on,
the glove compartment light is automatically
switched on when the glove compartment is
opened.
The compartment is lockable with the ignition
key to help prevent theft.
WARNING
Keep glove compartment door closed
while driving to prevent injury during a
collision.

42




Overhead Interior Light
Located between the two sun visors the
interior light has a three position switch.
Switch Positions
Rearward (a) - on continuously
Center (b) - off
Foreward (c) - on, only with doors open Sun Visors

To protect driver and passenger from side
glare, the sun visors can be moved to the
sides after lifting them out of their center
mounting.
The make-up mirror on the rear of the visor is
fitted with a protective sliding shutter.
43

Automatically Controlled
Air Conditioner
The air conditioning system works only when
the engine is running. Its refrigerating capacity depends on engine speed. If a high
refrigerating capacity is desired, it is
necessary to rev up the engine -
particularly in city or bumper-to-bumper traffic.
The air conditioning system can be turned on
at any air distribution position by pressing the
air conditioner switch. When the system is
turned on, the air conditioning compressor is
activated via a magnetic clutch.
Optimal cooling is achieved when the fan
control switch is at position 4, the windows are closed and the lateral as well as the
center dashboard vents are fully opened and
the temperature switch is set at maximum
cooling power.
When the air conditioning system is on,
additional cooled air enters the glove
compartment through a vent.
After prolonged exposure to sun, it is recommended that you ventilate the
passenger compartment with the windows
down and air conditioning on.
Should the air conditioning system fail, i. e.
uncooled air flows through the vents while the
system is switched on, have it checked in an
authorized workshop.


45

Functioning
The automatic system controls the passenger
compartment temperature in accordance with
the temperature preset by the temperature
knob.
The passenger compartment temperature is
kept constant under varying climatic
conditions.
Cold and warm air is automatically mixed by
means of air flaps operated by a servo motor.
The servo motor is controlled by a passenger
compartment temperature sensor, an ambient
temperature sensor and a temperature sensor located in the air conditioner.
There are several options to satisfy the
requirements of individual comfort with an
automatically controlled air-conditioning
system:
The upper level (2) is operated to direct the air flow towards the windshield (right position:
open; left position: closed).
The lower level (3) can be used to direct the
air flow to the footwell outlets (right position:
open; left position: closed). The positions of
these two levers are infinitely variable and can be set independently of one another. A higher or lower temperature range can be preselected by means of the temperature
control knob.

Air Conditioning System Maintenance The air conditioning system must be turned on for a short period of time at least once a
month. This instruction should be observed
particularly during the cold season to ensure
proper lubrication of the sealing rings and
compressor bearings.
For this purpose, set the temperature control
knob at maximum cooling temperature
(extreme counterclockwise position).
Check the compressor polyrib belt for proper
tension during regular maintenance.
Due to the loss of refrigerant, which is
technically inevitable, the refrigerant level in
the fluid reservoir should be checked at least
once a year.
If gas bubbles are visible over an extended
period of time in the inspection window of the
fluid reservoir while the air conditioner is
running, there is a deficit of refrigerant in the
air conditioning system. The brief appearance
of gas bubbles is due to technical reasons.
Should the air conditioning system fail, i. e.
uncooled air flows through the vents while the
system is switched on, have it checked by
your Porsche dealer.

Controls for Automatic Transmission
The selector lever has 6 positions:

Park
Rev erse

Neutral
Driv e
Low
Low




... If the selector lever is unintentionally mo ved
into Neutral (N) while driving, take your foot off
the accelerator pedal and wait until the engine
speed has dropped to idle before selecting a driving position.
Never shift into Reverse (R) or Park (P) when
the car is in motion.
... Never get out of the driver's seat when the
engine is running and the selector lever is not in the "P" position. Move the selector lever to
"P" and apply parking brake.
... Always make sure the selector lever is in the
"P" position when checking under the hood.
Otherwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied.
... A driving position must never be used for
holding the vehicle at rest uphill. Always use
your foot brakes when stopped on inclines.
Driving the Automatic Transmission
The Automatic Transmission has 3 forward
gears and one reverse. In driving positions D
and 2 the Automatic Transmission changes
gears automatically while driving.
Position D
is the driving position normally used for city and highway driving. It ranges from zero to top
speed, and all three gears shift automatically
depending on driving speed.

Start in Park
The selector lever has a push button in the
handle. The push button must be
depressed when selecting the following
positions:
From P to R
R to P depress push button
N to R in handle
2 to 1
The selector lever can be moved freely
between the other positions.
The respective position is illuminated in the tachometer as long as the ignition key is in
the ignition lock.
Remember the following basic rules:

... Apply the parking brake or foot brake before
selecting a driving position. When the selector
lever is in a driving position, the car may creep
even at idle speed. Therefore, do not release
the parking brake or foot brake until you are
ready to move.
... Do not accelerate while selecting a driving
position. Wait for positive engagement. At this
time the engine must run at idle speed so that
no undue stress will be placed on the automatic
clutches in the transmission.

Position 2
is to be used for mountain driving or slow
driving, when towing a trailer and also when
you want to make use of the engine's braking
effect. In "2", only the first and second gears
will engage automatically. Therefore, only shift down into position "2" when the speed is below 63 mph or 100 km/h. It is not necessary to let up on the accelerator.
Position 1
is needed on rare occasions. It should only be
used up to 25 mph or 40 km/h. In "1" the
transmission will stay in first gear and not shift
into the second or third gear.
Only shift down into "1" when driving speed is below 25
mph or 40 km/h.
The reverse position R
Reverse should be selected only when the car has come to a full stop and the engine is
running at idle speed.
The back-up lights come on automatically
when you engage Reverse (with ignition on). Starting the engine
is only possible when the selector lever is in
Neutral or Park (N or P) . As long as one of
the driving positions is engaged a safety
switch prevents the engine from being started.

Emergency starting
Your Porsche with Automatic Transmission
cannot be started by pushing or towing.
Should the engine fail to start see "Emergency starting with jumper cables" or consult your
nearest authorized Porsche dealer.
DO NOT START OR TOW the car without
ATF in the transmission, as this will result
in serious damage to transmission and
torque converter.
Putting the car in gear
With the parking brake or foot brake set, shift
into the position you wish to use, usually
position D. To accelerate, release the brake
and depress the gas pedal.
WARNING
Do not release the brake before you are
prepared to move, because power is
transmitted to the wheels as soon as a
driving position is engaged.
Selecting a driving position while driving
is easy. Simply release the accelerator pedal
and move the selector lever from the position
you are in into the position you want. Then
step on the accelerator again.
WARNING
Do not shift to a lower driving position
until vehicle speed has dropped below the
specified limits. Engine speed will sudden-

ly increase and may cause engine damage and loss of vehicle control.
Stopping
When stopping temporarily, at traffic lights for
example, it is not necessary to move the
selector lever to Neutral. Simply apply the
brakes. To start again release the brake and
accelerate.
Parking
When parking your car, apply the parking
brake first, and then move the selector lever to position P. To do this, depress the button and
push the lever through R to P. The
transmission is then mechanically locked.
Park may only be engaged when the car is
stationary.
Do not remove the key from the ignition
steering lock until you have parked the car, because removal of the key locks the
steering wheel.
Shift out of the Park position, before releasing
the parking brake.
When the car is parked on a steep hill, shifting
out of Park may be a little harder. This is due
to the weight the car exerts on the
transmission.
