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.

Headlight Washer
To operate the headlight washer, push the
washer lever in the direction of the dash-board (switch position 7). The system only operates when the headlights are switched on. A separate pump supplies high-pressure water to the spray nozzles located in front of the headlights on the bumper. The high
pressure stream soaks the dirt on the lenses
and washes it off. Repeat the wash cycle as
necessary to remove heavy dirt accumulation.
Since the system uses a lot of water, a
reservoir holding approx. 1,6 U.S. gals, or 6
liters has been installed in the engine
compartment. This reservoir also supplies the
windshield washer with water. Use windshield washer solvent with anti-freeze all year round,
so that both washer systems also function at
freezing temperatures.
Do not use engine coolant anti-freeze or
any other solution that may damage the
car paint.

In USA : Miles per hour and Kilometers per
hour
In Canada : Kilometers per hour
The upper odometer records total distance
driven and cannot be turned back.
33
Page 18 of 66
944 / 944 S
944 Turbo The trip odometer
in the lower part of the
speedometer can be turned back to zero by
pressing the reset-button, located in the left
section of the center dashboard vent. The
ignition must be on. Tachometer
The transistorized tachometer operates on the pulse count principle and shows engine speed in revolutions per minute (rpm).
The mark at the end of the scale indicates the
maximum permissible engine rpm. Before
reaching this area, the next higher gear
should be selected. Earlier shifting saves fuel.
Shift to the next lower gear when the engine
rpm drops below 1500 rpm.
The speed limiting governor prevents the
engine from being overrevved under load.
Boost Pressure Gauge
On the 944 Turbo there is a boost pressure
gauge in the lower part of the tachometer.
This instrument indicates the pressure in the
intake manifold.
With the ignition on and the engine stopped,
the indicated pressure corresponds to the
ambient air pressure (atmospheric pressure)
of approx. 1 bar.
Should an excessively high boost pressure
occur as a result of a defect, the fuel supply or the ignition is cut off automatically.
34
944 / 944 S
CASIS
Computer Assisted Shift Indicator System (Manual Transmission only) A computer continually evaluates vehicle data, such as driving speed, engine rpm, engine
load and engine temperature.
When the CASIS arrow in the tachometer
lights up, it means the engine could operate
more economically. The light indicates that
you can increase fuel efficiency by shifting into a higher gear. The CASIS light will go out when a higher gear has been engaged, when taking your foot off the accelerator pedal or when accelerating at a higher rate. In fifth gear the CASIS light is inoperative.
During maximum acceleration, the CASIS
arrow light will only light up at a point where
engine rpm is such that improved acceleration
can be obtained by shifting into the next higher gear. This means the CASIS arrow does not
indicate any set shift point, but that the
computer calculated shift points will depend on the way you drive. The arrow will light up at
the lowest speed range when cruising, and at
the highest speed range when accelerating
with wide open throttle.
How to use CASIS
Drive your Porsche shifting as you normally
would. As soon as the engine reaches uneconomical load range, the CASIS light will remind you to
shift into the next higher gear to keep the
engine at the same performance level but with lower fuel consumption.
You will get used to CASIS quickly and there
fore operate your Porsche with the CASIS
arrow light coming on only now and then.
WARNING
Use CASIS to your best advantage but
remember that traffic, road and weather
conditions must always have priority when shifting gears or changing speeds.

Left Instrument Cluster
The left instrument cluster includes the
coolant temperature and fuel gauges as well
as warning lights for coolant temperature, fuel
reserve, brake-
lining wear, safety belt, parking light and parking brake. The two arrows at the
top are turn signal indicators for vehicles with
trailer coupling.
Coolant temperature
Indicator
Needle in lower field - engine is cold
Avoid high speeds and high engine rpm. During cold engine operation, engine
response and power levels will vary from that
of a warm engine. Due caution and notice of
these engine characteristics will ensure safe
operation of the vehicle.
Needle in center field - normal
Under normal driving conditions, needle
should remain in center field. The needle may
reach the upper field, especially at high
engine loads, but should return to "normal"
when engine load is reduced.
Needle in upper field - warning
If needle enters the upper field the engine is
overheating the warning light comes on.
Reduce speed and engine rpm. The needle
should return to the center field and the
indicator light goes out.
If the needle does not return to the center
field, and the indicator light does not go out,
the radiator fan may not be working to
provide sufficient engine cooling. Pull off the
road and turn off the engine. The fan should
still be running for a while. Failure to do so
may result in severe damage to the 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 termoswitch
turns the fan on.
Be careful if you have to remove the cap from a hot coolant fluid reservoir. Protect
your hands, arms and face against
scalding. Use a thick rag and open the
cap carefully one turn to allow excess
pressure to escape before removing the
cap.
If the fan is not working, the fuse for the fan
may be burned out, or the relay may be
defective. See "Fuses and Relays".
After the engine has cooled down, check the coolant level (see "Cooling System"). If the
coolant level is low, top it up with water.
Check for possible leaks.
If the coolant level is normal, proceed to the
nearest workshop. Avoid idle speed and stop-
and-go driving. But with an inoperative fan,
the coolant will heat up again. When the
needle enters the upper field, stop again and
let the engine cool down before you continue
driving.
Coolant system malfunctions should be
remedied by the nearest Porsche dealer, as
severe engine damage may occur.
36
Fuel Gauge and FuelReserve Indicator
When the ignition is turned on, the amount of
fuel in the tank is indicated by the fuel gauge
in the right part of the dial.
If the needle enters the area in the bottom and the fuel reserve indicator lights up, there is
only a reserve of about. 2.1 U.S. gal/8 liters
left in the tank. Time to refuel at the next gas
station.
Brake Pad
Warning Light
The brake pad warning light comes on when the ignition is turned on and goes out after the engine has started.
If the light stays on when the engine is
running or comes on while driving, the brake
pads are worn, excessively.
Do not continue to operate the vehicle but
have your Porsche dealer check and
replace the brake pads.
Safety Belt
Warning Light
When the ignition is turned on the light will
come on for about 6 seconds to remind driver
and passenger to buckle up. See "Safety
Belts" for more details.
Parking Brake Light
The parking brake light will light up when the
ignition is turned on and the parking brake is
set.
The light goes out when the parking brake is fully released.
Parking Light
The parking light indicator at the bottom in the
left instrument cluster lights up when the
parking lights are switched on.
Turn Signal
Indicator Light
The turn signal indicator light, which is located below the central warning light, will flash at the same frequency as the turn signals. If a turn
signal fails, the control light flashes at about
twice the normal frequency. Have your dealer
check and repair it for you.
High Beam Indicator
Light
The high-beam indicator light, which is located at the top between the tachometer and the
right instrument cluster, will light up when you
switch on the high beams or when you flash
signal. The indicator goes out when you
switch to low beam.
Central Warning Light
The central warning light comes on after
turning on the ignition. This light monitors all
functions displayed by the instruments. If one
of these functions fails, the central warning
light and the pertinent indicator light come on
until the malfunction has been corrected. The
vehicle should immediately be taken to the
nearest authorized workshop.
37

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.

Heating and Ventilation
WARNING
Familiarize yourself thoroughly with the proper use and function of the
ventilation/heating, defogging/defrosting
and the air conditioning system.
For safe driving it is extremely important that you follow the operating instructions
in this manual. If in doubt, consult with
your Porsche dealer.
Maximum heating output and fast defrosting can be obtained only after the
engine has reached normal operating
temperature.
Before turning on the air conditioner, move the two air distribution control levers to
their center positions, and move the
temperature control knob to the extreme
counterclockwise position.
Should you suspect that the air
conditioner is damaged, have it checked
promptly. Leaks must be sealed
immediately, since loss of refrigerant may
result in serious damage to the air
conditioner system.
The upper lever (2) controls the air flow to the windshield" right position: open, left position: closed.
The lower lever (3) controls the air flow to the
footwell outlets (right position: open -left
position: closed).
The center dashboard vent can be opened or
closed by operating the lever (D). For closing,
the lever is pushed all the way up. For
opening, push the lever downward for the
desired air volume.
The direction of the air outlet is controlled by
means of handles (C, E) on the vents.
The side dashboard vents are opened or
closed by means of the lower levers (B, F) (
- open, - closed). Again, the air outlet direction is controlled by means of handles (A, G) on the vents.
Heater Control
Activation of the heater control system ensures temperature control in the passenger
compartment in accordance with the
temperature range preset by the temperature
knob. The passenger compartment
temperature is kept constant under varying
climatic conditions.
Fan Control Switch Knob
In order to ensure air circulation even with the
vehicle standing or moving at low speed, the
fan is running at low speed even at switch
position 0. If you desire more air flow, the fan
can be switched to steps 1 through 4.
Defroster Switch
Since the effectiveness of the heating
depends on the cooling water temperature,
the full heating power is not available until the
engine has reached its normal operating
temperature. To achieve the best defroster
effectiveness, the center dashboard vent must be closed entirely (push lever to its extreme
top position). Then press the defroster button - indicator light comes on. Independent of the
position of the upper and lower levers, high-
low temperature switch and the fan control
switch knob, the system automatically
switches to maximum heating power at fan
stage 4 and the full air flow is directed to the
windshield and the side dashboard vents.
Recirculation Switch
When you follow a truck or bus to prevent the
exhaust gases from entering your car through
the fresh air vents, press the recirculation
switch. The fresh air supply is then interrupted and air from inside of the vehicle will be
recirculated. The recirculation effect should
be utilized for only a short period of time to prevent windshield misting! 44b

Break-in Hints for the first 1.000 miles /
1.600 kilometers
There are no specific break-in rules for your
Porsche. However, by observing a few
precautions you can help extend the service
life and performance of your engine.
During the first 1.000 miles / 1.600 km, all
working components of the engine adjust to
each other to a certain degree. Therefore:
Avoid full throttle starts and abrupt stops. Change speeds frequently. Vary the throttle
load.
Do not exceed maximum engine speed of
5.000 rpm (revolutions per minute).
Do not run a cold engine at high rpm or in
Neutral.
Do not let the engine labor, especially when
driving uphill. Shift to the next proper gear in
time (use the most favorable rpm range).
There may be a slight stiffness in the steering, gearshifting or other controls during the break-
in period, which will gradually disappear.
Never lug the engine in high gear at low
speeds. This rule applies all the time, not
just during the break-in period.
Breaking in brake pads
Brake pads do not possess maximum braking
efficiency when the car is new. Therefore
more pedal force is necessary during the first
100 to 150 miles (150 to 250 km). This also
applies to replacement brake pads.
New tires
New tires do not possess maximum traction.
They tend to
be slippery. Break in new tires by driving at moderate speeds during the first 60
to 120 miles (100 to 200 km), and longer
braking distances must be anticipated.
Engine Oil Consumption
During the break-in period oil consumption
may be higher than normal.
As always, the rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant.
Check engine oil level, add if necessary. Make it a habit to have engine oil checked with
every fuel filling.

Engine Exhaust WARNING
Engine exhaust is dangerous if inhaled.
Never start or let the engine run in a closed garage. Never sit in your car for
prolonged periods with the engine on and
the car not moving.
Although exhaust fumes from the engine have many components which you can smell, they also contain carbon monoxide, which is a colorless and odorless gas.
Carbon monoxide can be fatal if inhaled.
If you smell gas fumes in the vehicle, drive with the windows open but keep the
hatchback closed. Have the cause
immediately located and corrected.
Because of inherent hazards, we do not recommend transporting objects larger
than those fitting safely into the luggage
compartment. Keep the hatchback closed
while driving to prevent poisonous
exhaust gas from being drawn into the
vehicle.
Never carry additional fuel containers in your vehicle. Such containers, full or
partially empty, may leak, cause an
explosion, or result in fire in case of a
collision.
Operating Your Porsche in other Countries Government regulations in the United States
and Canada require that automobiles meet
specific emission regulations and safety
standards.
Therefore cars built for the U.S. and Canada
differ from vehicles sold in other countries.
If you plan to take your Porsche outside the
continental limits of the United States or
Canada, there is the possibility that
unleaded fuel may not be available;
unleaded fuel may have a considerably lower octane rating. Excessive engine knock and
serious damage to both engine and catalytic
converter could result;
service may be inadequate due to lack of
proper service facilities, tools or diagnostic
equipment;
replacement parts may not be available or
very difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or
parts availability.
If you bought your car abroad and want to
bring it back home, be sure to find out about
shipping and forwarding requirements, as well as current import and customs regulations.
