Maintenance, Car Care
221
Power Steering Power steering is assisted by hydraulic auxiliary
forces.
The hydraulic fluid reservoir is located in the en-
gine compartment.
Note
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the steer-
ing system.
Warning!
Risk of accident resulting in serious personal
injury or death.
When the engine is stopped (e.g. when being
towed) or the hydraulic system fails, there is
no assistance for steering.
Therefore, substantially more force will have
to be exerted in order to steer.
fExercise great care when being towed.
fHave the fault remedied at your nearest author-ized Porsche dealer.
Checking hydraulic fluid fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 206.
fOnly use hydraulic fluid authorized by Porsche.
Specification:
Please see the chapter “CAPACITIES” on
Page 290.
Check the fluid level with the engine stopped and
cold (approximately 68 °F/20 °C).
1. Open the engine compartment lid.
2. Open the reservoir cap.
3. Wipe measuring rod.
Close cap and reopen. The fluid level should lie
between the “MIN” and “MAX” marks.
Add hydraulic fluid if necessary.
4. Close cap carefully.
Close engine compartment lid.
Noticeable loss of fluid indicates leakage in the
system.
The cause should be remedied immediately at an
authorized Porsche dealer.

Practical Tips, Emergency Service
263
Winter operation The capacity and ability of the battery to store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in
winter months, e.g. by the heated rear window,
more frequent use of additional lights, the fans
and the windshield wipers, etc.
fHave the battery checked before the start of
winter.
Maintenance note
Keep the battery well charged to prevent it
from freezing.
A discharged battery can freeze at 23 °F (--5 °C),
but a fully charged battery only freezes at -- 40 °F
(--40 °C).
A frozen battery must always be thawed before
connecting jump leads.
Replacing battery The service life of the battery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
fOnly use an original Porsche battery, with the
correct part number, as a replacement.
fPlease observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
fPerform adaptation of the power windows:
Please see the chapter “STORING END
POSITION OF THE WINDOWS” on Page 26.

Fuel qualityYour engine is designed to provide optimum performance and fuel economy using
unleaded premium fuel with an octane rating of 98 RON (93 CLC or AKI).
Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI),
since the engine’s “Electronic Oktane™ knock control” will adapt the ignition timing, if necessary.
