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.

Ignition/Starter Switch with Steering Lock
The steering is equipped with an anti-theft
ignition lock.
Switch positions
0
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

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

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.
35

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.
53

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.

54

Neutral
Shift to this position for standing with brakes
applied.
Never use Neutral for coasting downhill.
You may lose control over the car because of reduced braking and cause serious damage to the transmission when a driving range has to be selected. CAUTION: While driving with the automatic speed control set (at speeds above 25 mph or 40 km/h), do not bring shift lever into
the Neutral position as excessive engine
rpm and severe engine damage may result.
Maneuvering
When alternating between forward (D) and
reverse (R) (for instance, while maneuvering
the car into a tight parking space), only shift
into Reverse or Drive
when the car has come to a full stop and the engine is running at idle
speed.
Stuck in snow, mud or sand
When alternating between Drive and
Reverse in an effort to free the vehicle,
depress the accelerator pedal lightly while the
transmission is in gear, and release the
accelerator pedal while shifting. Do not race
the engine and avoid spinning the wheels.
Do not repeat "rocking" back and forth
with wheels spinning at high engine speed
and heavy throttle, as serious damage may be caused to the automatic transmission
and other critical parts.
If you cannot free the vehicle after a few
"rocking" attempts, call for help or a tow truck.
Accelerator Pedal

For good fuel economy we recommend
smooth and even acceleration. Very fast, racy
driving, alternating between full throttle and
hard braking, raises the fuel consumption
considerably. Also, tires and brake linings
wear faster. It is more economical to drive smoothly and at a fairly constant speed.
Accelerator "Kickdown"
When depressing the accelerator pedal you
will find resistance near the full throttle position. By applying greater pressure the
pedal can be pushed beyond this point to the
kick-down position. The transmission will now
shift automatically into the next lower gear to
give you maximum acceleration, and only shift up again after the engine has reached
maximum speed in that particular gear.
WARNING
Be careful when using the kickdown on
slippery roads. Rapid acceleration may
cause skidding.
Please observe the following when applying
the accelerator kickdown:
With the selector lever in D, you can apply the kickdown to make the transmission shift down into second gear when driving below 88 mph
or 140 km/h and down to first gear when
driving below 47 mph or 75 km/h.
With the selector lever in "2", you can apply
the kickdown to make the transmission shift
down into first gear when driving below 47
mph or 75 km/h.
As soon as you release the pedal from the kickdown position the next higher gear is
automatically engaged.
Please observe all local and national speed limits.

9. When air bubbles at vent plug disappear, tighten the plug (required torque is 15-18
Nm or 11-13 ft lb).
10.
Check coolant level in tank and top up to
"max" mark, if necessary.
11.
Reinstall the expansion tank filler cap. After a test drive recheck the coolant level. See "filling capacities" for amount
required.


Manual Transmission oil
Both transmission and final drive are
combined in one housing. The lubricant used
is hypoid oil.
The manual transmission oil should be
checked and changed by your Porsche dealer
and at the intervals specified in your
Maintenance Schedule.
77



Automatic Transmission Fluid The torque converter and the transmission are lubricated with Automatic Transmission Fluid
(ATF). The final drive requires hypoid oil SAE
90 only.
Do not tow the car or run the engine
without ATF in the transmission.
Checking the ATF level
The ATF has to be checked at frequent
intervals, for instance, when the engine oil is
being checked or at least at the specified
intervals (see Maintenance schedule). A
correct ATF level is very important for the
proper functioning of the transmission. The
reading should be done when the ATF is warm, with the engine idling, the selector lever in Neutral and the parking brake applied.
The level of the ATF fluid can be checked
visually through the transparent reservoir. This reservoir is located at the rear end of the
transmission housing. You have enough ATF
if the fluid level is between the Min. and Max.
marks. It should never be above or below
these marks.
The difference between the two marks is 1
U.S. pint or 0.4 liter.
If level is too high or too low do not just add or
drain ATF. Have your dealer check and
correct the cause as soon as possible.
For correct ATF specifications, see "Filling
Capacities".
Changing the ATF

The ATF and the hypoidoil in the final drive
has to be changed at specified intervals (see
Maintenance schedule).
