Rear View Mirrors

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

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


When you turn on the rear window defogger,
the outside rear view mirror is also heated.
The outside mirrors are ad
justable from inside of the vehicle by a four direction switch
located on the left door and a rocker switch
located on the center console ahead of the
gear selection lever. The rocker switch (A)
selects either the left or right mirror for
adjustment. Push
the rocker switch forward to select the left mirror, and rearward to select
the right mirror. Then the four direction switch
will adjust the selected mirror in any of the four directions.
The mirror housing is hinged and can be
folded flat against the c
ar in either direction to prevent damage in tight parking spots.
If necessary, the outside mirrors can also be
adjusted manually.

Cigarette Lighter
Push knob on console in. When ready for use, the lighter will snap back. With the lighter
removed, the socket may be used for small
appliances, such as shaver, hand vacuum
cleaner or air compressor to inflate the
collapsible spare tire. Maximum rating of such
equipment should not exceed 120 W/12 Volt.
Do not damage the socket by trying to
insert plugs of the wrong design.



Rear Window Defogger
The rear window defogger works only with the
ignition key in positions 1 and 2.
The rear window defogger, together with the
flow through ventilation, will help to keep the
inside of the rear window clear of
condensation and frost in the winter.
Depress the switch to turn on the rear window
defogger.
The control light in the switch will light up to
remind you that the defogger is switched on.
After the rear window has been cleared, switch off the rear window defogger to avoid
unnecessary drain on the battery.
Emergency Flasher
If your car is disabled or parked under
emergency conditions, depress the HAZARD
switch to make all four turn signals flash
simultaneously. The light in the switch flashes
at the same frequency.
The emergency flasher works
independently of the ignition switch
position.
WARNING

Whenever stalled or stopped for emergency repair, move the car well off
the road. Turn on the emergency flasher
and mark the car with road flares or other
warning devices. Do not remain in the car.


Do not park or operate the car where the hot exhaust system may come in contact
with dry grass, brush, fuel spill or other
flammable material.
Before working on any part in the engine compartment, turn the engine off and let it cool down sufficiently. Hot components
can burn skin on contact.
Remember the coolant fan is thermostatically controlled and may come on at anytime, regardless of ignition
switch position.

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

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.

Fuel Economy
Fuel economy will vary depending on where,
when and how you drive, optional equipment installed, and the general condition of your
car. A car tuned to specifications and correctly maintained, will help you get maximum fuel
economy.
Have your vehicle tuned to specifications.
Fuel injection should be adjusted to
specifications.
Spark plugs should be clean, properly
gapped and fire efficiently.
Air cleaner should be dirt free to allow proper engine "breathing". Battery should be fully charged. Wheels should be properly aligned. Tires should be inflated at correct pressures. Keep a light foot on the accelerator pedal. Drive smoothly, avoid abrupt changes in
speed as much as possible.
Avoid jack rabbit starts and sudden stops. Do not drive longer than necessary in the
lower gears. Shifting up early helps to save
fuel.
Avoid unnecessary idling. Turn the engine
off.
Prolonged "warm up" idling wastes gas. Start the vehicle just before you are ready to drive. Accelerate slowly and smoothly.


Any additional weight carried in the vehicle reduces fuel economy. Always keep cargo to
a minimum and remove all unnecessary
items.
Organize your trips to take in several
errands.
Use air conditioner only when needed. All electrical equipment contribute to increased fuel consumption.
The EPA estimated m.p.g. is to be used for
comparison purposes, actual mileage may be
different from the estimated m.p.g., depending on your driving speed, weather conditions and trip length. Your actual highway mileage will
probably be less than the estimated m.p.g.
Please observe all local and national speed
limits.


49


Fuel Filler Cap
The lockable fuel filler cap is on the right side
panel of the car. When putting the cap back
on, twist it clockwise until it stops with an
audible click.
We recommend you turn off the engine
when filling the fuel tank.
Fuel tank capacity is listed under "Filling
Capacities".
If you lose your fuel filler cap, replace it
immediately with a cap of the same design to
reduce the possibility of a fire in a collision.
Fuel Recommendation
Your Porsche is equipped with a catalytic
converter and must use UNLEADED FUEL
ONLY.
944:
Minimum octane rating is 91 RON (87
CLC or AKI rating on US fuel pumps).
944 S / 944 Turbo: Minimum octane rating is
95 RON (90 CLC or AKI rating on US fuel
pumps).
Federal law prohibits use of leaded fuel in
this vehicle.
The use of UNLEADED FUEL ONLY is
critically important to the life of the catalytic
converter. Deposits from leaded gasolines will ruin the converter and make it ineffective as
an emission control device.
Cars with a catalytic converter have a smaller
fuel tank opening, and gas station pumps
have smaller nozzles. This will prevent
accidental pumping of leaded fuel into cars
with a catalytic converter.
Unleaded fuels may not be available outside
the continental U.S. and Canada. Therefore,
we recommend you do not take your car to areas or countries where unleaded fuel may
not be available.
Octane ratings
Octane rating indicates a gasoline's ability to
resist detonation. Therefore, buying the
correct octane gas is important to prevent
engine "knock" and possible engine damage.
The 91 RON (95 RON) octane rating of your
car is based on the research method. The CLC (U.S. Cost of Living Council octane
rating) or AKI (antiknock index) usually
displayed on U.S. gasoline pumps is
calculated as research octane number plus
motor octane number, divided by 2, that is
written as:


The CLC or AKI octane rating is usually lower
than the RON rating:
91 RON equals ............ 87 CLC or AKI
95 RON equals ............ 90 CLC or AKI

50

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.

55





Hatchback

The hatchback can also be opened with the
ignition/door lock key. Turn key
counterclockwise and lift hatchback up.
To close, push hatchback down firmly until
both locks snap shut. Pull up on hatchback to
make sure it is securely locked.
Keep the hatchback locked at all times to
prevent unauthorized access to the
vehicle.
Be careful when removing large objects
through th
e rear. Sharp edged objects may damage the defogger wires in the rear
window.
WARNING
Because of inherent hazards, we do not
recommend transporting objects larger
than those fitting safely into the luggage
compartment. Keep the hatchback closed
while dr
iving to prevent poisonous exhaust gas from being drawn into the vehicle.
