Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may cau-
se serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel fu-
mes might be present. Be especially cautious
of such devices such as hot water heaters
which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all ti-
mes while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral or the se-
lector lever is in position P or N. fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), je-
welry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high vol-
tage is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cove-
rage.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
Power measurements Power measurements on dynamometers are not
approved by Porsche.

Wiper BladesfWhen wiper performance deteriorates, replace
the wipers.
fPlease observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 191.
Caution!
Risk of damage if the wiper arm accidentally
falls back on to the window.
fAlways hold the wiper arm securely when re-
placing the wiper blade.
Risk of damage if wiper blades that are fro-
zen in place are loosened improperly.
fThaw the wiper blades before loosening them.
Maintenance note
If the wiper blades rub or squeak, this can be as a
result of the following:
– If the vehicle is washed in an automatic car
wash, residues may adhere to the windshield.
These residues can only be removed using a
special cleaning solution.
Please contact your authorized Porsche dealer
for further information.
– The wiper blades may be damaged.
fReplace damaged wiper blades as soon as
possible.
Changing windshield wiper blades
Caution!
Risk of damage.
If a wiper blade is not changed properly, it
can come loose when the car is moving.
fCheck whether the wiper blade is seated
securely.
The wiper blade must engage the wiper arm properly.
1. Apply the handbrake.
2. Switch the wipers off (position 0) and remove
the ignition key.
3. Fold windshield wiper arm away from the
windshield.
A- Passenger’s side, curved wiper blade
B- Driver’s side, wiper blade with spoiler4. Press together the plastic spring of the wiper
blade (right arrow).
Pull wiper blade out of wiper arm.
5. Insert new wiper blade until you feel it engage.
Ensure that the new wiper blade is inserted
into the wiper arm in the same position:
– direction of the spoiler on the driver side,
– curvature on the passenger side.
6. Carefully fold wiper arm back onto the wind-
shield.

A - Coolant expansion tank cap
B - Coolant level Coolant Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 168.
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 with its filler orifice is in the
rear luggage compartment.
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.”
markings.
Topping off coolant
Warning!
Danger of serious personal injury from scal-
ding. Coolant is hazardous to your health,
and may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children’s reach.
fAlso, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open contai-
ner. Coolant can be deadly to pets if consu-
med.
Risk of damage from overflowing coolant.
fTake care while topping off coolant not to soil the luggage compartment or items of luggage.

Maintenance, Car Care
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 lub-
ricant.
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 le-
vel 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 dus-
ty, 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 dri-
ving 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 re-
gularly and kept at the required level.
– Make it a habit to have the engine oil level che-
cked 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 occuring when lit, if en-
gine rpm is above idle speed.
