Power Steering
Warning!
Risk of accident.
When the engine is stopped (e.g. when on
tow) or the power steering has failed there is
no steering assistance.
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 autho-rized Porsche dealer. Note
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the stee-
ring system.
Checking hydraulic fluid fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 168.
The hydraulic fluid reservoir is located in the engi-
ne compartment.
fOnly use hydraulic fluid authorized by Porsche.
fPlease observe the chapter “CAPACITIES” on
Page 266.
fCheck the fluid level with the engine stopped
and cold (approximately 68°F/20°C).
1. Open the engine compartment lid.
Please observe the chapter “OPENING ENGINE
COMPARTMENT LID” on Page 185.
2. Open the reservoir cap.
3. Wipe measuring rod.
Close lid and reopen. The fluid level should lie
in the area below the ”Cold“ marking.
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
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 qualified
specialist workshop.
Have the fault remedied.
4. After the warnings disappear, stop the vehicle
in a suitable place.
5. Perform adaptation of the power windows:
Please observe the chapter “STORING END
POSITION OF THE WINDOWS” on Page 29.Ignition key/ignition lock
fDo not insert the ignition key into the ignition
lock if the vehicle battery is discharged.
The ignition key can no longer be removed.
The key cannot be removed until the vehicle elec-
trical system is supplied with power again.
fPlease observe the chapter “EMERGENCY UN-
LOCKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 228.
6. Please observe the chapter “JUMP LEAD
STARTING” on Page 236.

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.
