Coolant Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31°F/–35°C.
Only use antifreeze authorized by Porsche. Checking coolant level The expansion tank for the coolant is located in
the rear luggage compartment under the service
flap.
fCheck the coolant level regularly at the trans-
parent window of the expansion tank.
When the engine is cold and the car is level the flu-
id level must lie between the “Min.” and “Max.”

4. If necessary, add a mixture of equal parts anti-
freeze and water.
Do not fill over the “max” marking.
Antifreeze in coolant:
50% gives protection down to –31°F/–35°C
60% gives protection down to –58°F/–50°C
5. Screw cap firmly on.
6. Close service flap.If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
Radiator fansThe radiator and radiator fans are in the front of
the vehicle.
Warning!
Risk of injury. The fans can start running as
a function of temperature, even with the
engine switched off.
fExercise extreme caution when working in the area of the radiator fans.

Engine Oil Engine oil consumption
It is normal for your engine to consume oil.
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 lubri-
cant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil lev-
el at all, even after 600 miles (1000 km) or more.
This is because the oil is gradually becoming dilut-
ed with fuel or moisture, making it appear that the
oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater. If the vehicle is driven at a high rate of speed, cli-
matic conditions are warm, and the load is high,
the oil should be checked more frequently, as driv-
ing conditions will determine the rate of oil con-
sumption.
– The engine in your vehicle depends on oil to lu-
bricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked with every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occurring when lit, if
engine rpm is above idle speed.
Engine Oil Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
fRegularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please observe the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 110.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.2 liters.
Each segment of the display corresponds to
approx. 0.4 liter.

Topping off engine oil
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
fKeep engine oil out of children’s reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
fAlways protect your skin by washing thorough-ly with soap and water. Caution!
Risk of damage from overflowing engine oil.
fTake care while checking and topping up en-
gine oil not to soil the luggage compartment or items of luggage.
The oil inlet opening is in the rear luggage com-
partment under the service flap. 1. The on-board computer indicates how much oil
must be added.
2. Press catch button on the service flap and
open flap.3. Unscrew cap of the oil filler opening.
4. Add at most half a liter of engine oil at a time.
5. Measure oil level again with the on-board
computer.
6. Add more engine oil if necessary.
Never add more engine oil than required
to reach the max. mark.
7. Close cap carefully.
8. Close service flap.

Brake Fluid Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 172.
fUse only new (unused) Original Porsche
brake fluid.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
fKeep brake fluid out of children’s reach.
fTake care while topping off brake fluid not to
soil the luggage compartment or items of lug-gage.
Checking the brake fluid level The reservoir for the hydraulic braking and clutch
systems is in the front luggage compartment.
1. Open and remove cover flap A.
2. Regularly check the brake-fluid level on the
transparent expansion tank through the win-
dow B.
The fluid level should always lie between the
“Min” and “Max” marks. A slight decrease in the fluid level due to wear and
automatic readjustment of the disc brakes is nor-
mal.
If, however, the fluid level falls markedly or below
the “Min” mark, the braking system may have de-
veloped a leak.
fHave the braking system checked immediately
at an authorized Porsche dealer.

Maintenance, Car Care
183
Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating con ditions,
can affect braking performance.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the bro-
chure “Maintenance”. The brake-fluid warning lights in the instrument
panel and on-board computer indicate:
– brake-fluid level too low,
– in conjunction with large pedal travel, braking-
circuit failure.
If the warning lights should light up while
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.

Fuels containing MMT Some North American fuels contain an octane en-
hancing additive called methylcyclopentadienyl
manganese tricarbonyl (MMT).
If such fuels are used, your emission control sys-
tem performance may be negatively affected.
The check engine warning light on your instrument
panel may turn on.
If this occurs, Porsche recommends you stop us-
ing fuels containing MMT.

Emission Control System In the interest of clean air Pollution of our environment has become a prob-
lem that is of increasing concern to all of us. We
urge you to join us in our efforts for cleaner air in
controlling the pollutants emitted from the auto-
mobile.
Porsche has developed an emission control sys-
tem that controls or reduces those parts of the
emission that can be harmful to our environment.
Your Porsche is equipped with such a system.
Porsche warrants the Emission Control System in
your new car under the terms and conditions set
forth in the Warranty Booklet.
You, as the owner of the vehicle, have the
responsibility to provide regular maintenance serv-
ice for the vehicle and to keep a record of all main-
tenance work performed. To facilitate record
keeping, have the service performed by author-
ized Porsche dealers. They have Porsche trained
technicians and special tools to provide fast and
efficient service.
To assure efficient operation of the
Emission Control System fHave your vehicle maintained properly and in
accordance with the recommendations de-
scribed in your Maintenance Booklet.
Lack of proper maintenance, as well as im-
proper use of the vehicle, will impair the func-
tion of the emission control system and could
lead to damage.
fDo not alter or remove any component of the
emission control system.
fDo not alter or remove any device, such as
heat shields, switches, ignition wires, valves,
etc., which are designed to protect your vehi-
cle’s emission control system.
In addition to serious engine damage, this can
result in a fire if excess raw fuel reaches the ex-
haust system.
fDo not continue to operate your vehicle if you
detect engine misfire or other unusual operat-
ing conditions.
Parking
Warning!
Danger of fire.
fDo not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or oth-
er flammable material.
