Power Steering Power steering is assisted by hydraulic auxiliary
forces.
The hydraulic fluid reservoir is located in the
engine compartment.
Note
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the
steering 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 autho-rized Porsche dealer.
Checking hydraulic fluid fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 157.
fOnly use hydraulic fluid authorized by Porsche.
Specification:
Please see the chapter “CAPACITIES” on
Page 239.
Check the fluid level with the engine stopped and
cold (approximately 68 °F/20 °C).
1. Start the engine and let it idle for approx.
20 seconds.
Switch off the engine.
2. Open the engine compartment lid.
3. Open the reservoir cap.
4. Wipe measuring rod.
Close cap and reopen. The fluid level should lie
in the area of the “COLD” marking.
Add hydraulic fluid if necessary.
5. 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.

CapacitiesUse only fluids and fuels authorized by Porsche. Your authorized Porsche dealer will gladly advise you.
Your Porsche has been designed so that it is not necessary to mix any additives with oils or fuels.
EngineOil change quantity without oil filter approx. 9.25 quarts / 8.75 liters
Oil change quantity with oil filter approx. 9.5 quarts / 9 liters
Please see the chapter “ENGINE OIL” on Page 159.
Coolantapprox. 7.9 U.S. gallons / 30 liters
Manual transmission
and differential
approx. 3.5 quarts / 3.3 liters transmission oil SAE 75W-90, Mobilube PTX
Fuel tank approx. 17.7 U.S. gallons / 67 liters
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 Octane™ knock control” will adapt the ignition timing, if necessary.
