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.

Speedometer

The speedometer indicates driving speed per
hour.
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

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

Tar or oil
Do not allow tar or oil to remain on the paint.
Remove as soon as possible with a cloth
soaked with a special paint cleaner. If you do
not have a tar or oil remover, you may
substitute with turpentine. After applying a
cleaning fluid, always wash with a lukewarm
soap water solution and apply a new wax
coat.
Insects
Remove as soon as possible with a lukewarm
soap/water solution or apply insect remover.
Tree sap Remove with a lukewarm soap/water solution. Do not allow tree sap or bird droppings to
harden on the paint.
Windows
Keep silicone sprays off the windshield to
avoid wiper smear in rain.
Generally, highway dust that settles on the
outside of the windshield contains material
worn from tires and oil residues. On the inside surfaces of the windshields, particularly in
strong sunlight, there are build-ups of dust
from the interior decor. These buildups are
reinforced by pollution in the air

brought in with the fresh air supply. Use a
lukewarm soap/water solution or an alcohol
based commercial window cleaning agent for t
he inside and outside. If a chamois is used for polishing the glass, it should exclusively be
used for that purpose.
To assure that windshield washers also
function at freezing temperatures, antifreeze
must be added to the washer fluids reservoirs
beforehand. It is advisable to use window
washer solvent with anti-freeze all year round. Follow directions on the can for the right
amounts to be used. Do not use engine
coolant anti-freeze or any other solution
that can damage the paint.
In vehicles with Sekurif
lex windshields, the plastic coating on the inside of the
windshield must not have gummed labels
put on it or be cleaned using abrasive
agents or dry methods. If very dirty, it can
be cleaned with benzine. The use of
benzine in a confined environment may be
dangerous to your health. Make certain
that the plastic coating is not damaged in
cleaning by hard objects such as jewelry
or wristwatches.
Do not remove ice on the inside of the
windshield by any means except warm air
from the defroster nozzles. Do not use any
deicer sprays, scratching tools, or
scrapers!

A foil base must be applied to the windshield prior to application of any labels or stickers
such as those used for state registration or
inspections. Failure to utilize foil base
between sticker or label and the Sekuriflex
coating will result in damage to the Sekuriflex
coating. Three foil bases were included with
the vehicle and additional foil bases may be
ordered from any Porsche dealer.
Instructions:
1. Clean the windshield in the area for
application.
2.
Cut the base of the foil to the required size.
Round off the edges.
3.
Pull off the protective film.
4. Spray the gummed side of the foil base and the windshield with a soap solution (distilled water and liquid soap or grease-free
detergent in a mixing ratio 10:1).
5.
Apply the foil base to the windshield and spray it once again.
6. Any liquid and bubbles under the foil base must be brushed out using a flexible plastic
scraper.
7.
Dry the windshield using a soft cloth.
8. Install label/sticker on the foil base.
63

When removing the label/sticker or the
backing foil, first spray the foil with a soapy
solution (see point 4).
Wiper blades
Always loosen frozen wiper blades from glass as they may tear otherwise.
Remove all wiper blades periodically and
clean them thoroughly with an alcohol base
cleaning solution. Use a sponge or soft cloth
and wipe lengthwise.
Weatherstrips
To seal properly, weatherstrips around hood,
hatch, windows, doors, etc., must be pliable.
Spray with silicone or coat with talcum powder or glycerin to retain flexibility of the rubber and to protect against freezing in the winter.
Light alloy wheels
To preserve the decorative appearance of the
light aluminium castings, some special care is
necessary. Aside from road dirt and salt
sprays, brake metal dust will exert corrosive
effects.
If left on too long, brake metal dust can cause
pitting. Wash the wheels with a sponge or
hose brush every other week.

Roads salts should be removed weekly with
an acid free cleaning solution.
The acid free cleaning solution must not have
a pH value greater than 10 (see explanation),
in case of doubt, it is recommended to check
with the manufacturer of that particular cleaner.
Every three months (after regular cleaning)
the wheels should be coated with petroleum
jelly. Rub it in firmly with a soft cloth. Never use abrasive or metal polishing cleaning
agents.
Explanation of pH value
The pH value is a measurement for the
hydrogen-ion concentration in a liquid. This
value tells if the liquid reaction is sour (acid) o r alkaline (lye solution). At a pH value of 7, the reaction of the liquid is
neutral (that is, chemically clean water), it is
not an acid or alkaline. Acids have a pH value
under 7, the strength of the acid increases
with a lower pH value. Alkaline lies between a pH value of 7 and 14, the strength of the
alkaline increases with higher pH values.

For example: a mineral water mixed with
carbon dioxide has a pH value of 6-6.5,
reaction is also light sour. Battery acid in
comparison has a pH value of 1.
or
the pH value for normal soap solution is 8-9,
but the soap solution for a dishwasher is
approximately 12.5, this would not be suitable
for wheel cleaning.
Your Porsche dealer can advise you which
product to use.
Remember that moisture and road salt on
brakes may affect braking efficiency. Test
the brakes after each car or wheel wash.


64

Power Assisted Steering
The hydraulic assistance system allows
effortless steering under all driving conditions.
Slight hissing or squeaking sounds during
sharp turns (turning steering wheel from lock
to lock) are normal and do not indicate a
defective steering mechanism.
If the engine is not running, po
wer assisted steering is no longer effective. You can
continue to steer the car but more effort
will be required to turn the steering wheel.

Checking the fluid level
The hydraulic fluid level should be checked at
regular intervals. The fluid reservoir is
mounted on the right wheel housing in the
engine compartment.
1.
Unscrew cap from reservoir and wipe
dipstick with a lint free cloth.
2.
Let engine run at idle speed. Reinstall cap
and unscrew again. The fluid level should
be between the upper and lower mark on
the dipstick.
If necessary, top up with ATF-Dextron®.
3. Reinstall cap and handtighten securely.
73

Cooling System
Only use additives recommended for
aluminium engines and radiators. Your
Porsche dealer will be able to advise you.
For year round driving, phosphate-free
antifreeze is added at the factory for
temperatures down to:
-31° F / -35° C
Because of its anti-corrosion properties,
antifreeze should also remain in the cooling
system for summer operation. Cooling system capacity and specified antifreeze and water
ratios are listed under "Filling capacities".
Use any quality phosphate-free anti-freeze
containing ethylene glycol, available at your
Porsche dealer. Anti-freeze other than
specified by Porsche for aluminium engi-
nes and radiators may cause corrosion of
the cooling system, leading to engine
overheating and damage.

Only
for topping up coolant, a small amount of anti-freeze containing ethylene glycol and
phosphates may be used if recommended
anti-freeze is not available.
The anti-corrosion properties and the
antifreeze consistency will diminish gradually.
We recommend renewing the coolant mixture
at least every 2 years.
WARNING
The radiator fan is electrically driven. It is
switched on automatically by a thermostat
when the coolant reaches 198°F / 92°C.
Even when the engine is turned off, the fan will continue running, until the coolant
temperature has dropped to 189°F / 87°C
and until the engine itself has cooled down sufficiently.
Checking coolant level in expansion tank
A correctly functioning cooling system requires only minor care. The coolant level
should be checked from time to time, and
always before going on a longer trip.
The
expansion tank with filler cap opening is
located in the engine compartment (see
illustration). Since the expansion tank is
transparent, the coolant level can be checked
visually without removing the filler cap.

74

944 Turbo

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).

5. Press together the housing cover with the air intake funnel (944 Turbo) and carefully
place in position. Tighten fastening screws,
connect hose and screw down hose clamp.

944 S
1. Unscrew the retaining screws and remove
the filter cover.
2.
Remove the filter element.
3. Clean the inside of the filter housing with a
lightly oiled lint-free cloth.
4.
Fit a replacement filter element. Carefully
place the housing cover in position and
tighten the retaining screws.

Reservoir for Windshield and Headlight
Washer System
The transparent reservoir is in the engine
compartment. As clear water is usually
inadequate for cleaning windshield or
headlights, add a cleaning solution, such as
windshield washer solvent and antifreeze offered by your dealer. To assure that the
system also functions at freezing
temperatures, antifreeze must be added to the water beforehand. Follow the instructions on the can for the right amount to be used (also
see "Filling Capacities"). Do not use engine
coolant anti-freeze or any other solution
that can damage the car paint.
81

Tires/Wheels
The original equipment tires and wheel rims
on your Porsche comply with all applicable
Federal Motor Vehicle Safety Standards.
For your driving safety remember the
following:
Wheel rims and wheel bolts are matched to
fit your Porsche.
If you intend to use other than original equipment wheels, be sure that they conform to Porsche specifications for your model. The use of wheel rims and wheel bolts that
do not meet specifications of the original
factory installed equipment will affect the safe operation of your vehicle. Before you plan on exchanging wheels, or winter tires already mounted on wheel rims, consult your Porsche dealer. He has the
technical information necessary to advise
you which wheel rims and wheel bolts are
compatible with the original factory
installations.
Tire pressures
WARNING
Incorrect tire pressures cause increased
tire wear and adversely affect road holding of the vehicle, leading to loss of control.
Always use an accurate tire pressure
gauge when checking inflation pressures.
Do not exceed the maximum tire inflation
pressure listed on the tire sidewall. (Also
refer to "Technical data"). Cold tire infla-

tion pressure means: when a car has not been driven for at least 3 hours or less
than 1 mile. Never let any air out of warm
tires to meet cold tire pressure
specifications.
Tire traction
WARNING
When driving on wet or slushy roads, a
wedge of water may build up between the
tires and the road. This phenomenon is
known as aquaplaning and may cause
partial or com
plete loss of traction, vehicle control or stopping ability. Reduce speed
on wet surface.
Tire Life
Tire life depends on various factors, i.e.,
roads, traffic and weather conditions, driving
habits, type of tires and tire care.
Inspect your tires at least
every 2.000 miles or 3.000 km for wear and damage. If you notice
uneven or substantial wear, wheels might
need alignment or tires should be balanced or
replaced.
Tires must always remain on same side of
vehicle.
After changing, adjust tire pressure and torque wheel nuts diagonally to 94 ft Ibs (130 Nm) (see "Changing wheels").
The supposition that tire durability and
performance are immune to the effects of
storage and age is unfounded. Chemical
additives, which make the rubber elastic, lose
their effectiveness in the course of time and
the rubber becomes brittle and cracks.

Therefore, the tires, especially the collapsible
spare tire, should from time to time undergo a
visual check. To accomplish this,
pump up the collapsible spare tire.
Under no circumstances should tires older
than 6 years be used on your Porsche. The
age of the tire can be obtained from the "DOT" code number. If, for example, the last three
numbers read 125, then the tire was produced in the 12th week of 1985.
Tire wear
The original equipment tires on your Porsche
have built-
in wear indicators. They are molded into the bottom of the tread grooves and will
appear as approximately 1/2 in (12 mm)
bands when the tire tread depth is down to
1/2 of an in (1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the
tires. We recommend, however, that you do
not let the tires wear down to this extent. Worn tires cannot grip the road surface properly,
and are even less effective on wet roads.
In the United States, state laws may govern
the minimum tread depth permissible. Follow
all such laws.
WARNING
Do not drive with worn tires or tires
showing cuts or bruises as they may lead
to sudden deflation.
If you notice that tires are wearing unevenly,
consult your Porsche dealer. Uneven wear

traces may cause severe
corrosion in the brake system.
Coolant reservoir
Antifreeze must remain in cooling
system all year round.
Coolant level should be between
minimum and maximum mark
when engine is cold. Always add antifreeze and water in ratio specified under "Filling
Capacities".
Use quality antifreeze containing
ethylene glycol.
