Power Steering
Warning!
Risk of accident. When the engine is station-
ary (e.g. when on tow) or the hydraulic sys-
tem fails, there is no assistance for steering.
Therefore, substantially more force will have
to be exerted.
fExercise great care when on tow.
fHave the fault remedied at your nearest author-ized Porsche dealer.The flow noise heard at full steering lock is design-
related and does not indicate a de fe ct in the ste er-
ing system.
Checking hydraulic fluidfUse only hydraulic fluid authorized by
Porsche.
fCheck the fluid level with the engine stopped
and cold (engine temperature approx. 68° F or
20°C).
1. Remove cover A.
2. Open the reservoir cap.
3. The fluid level should lie between the MIN and
MAX marks on the dipstick.
Add hydraulic fluid if necessary.
4. Close cap carefully.
5. Put on cover A.
6. Close engine compartment lid.
fIf the fluid level drops significantly, please have
the cause remedied immediately by an author-
ized Porsche dealer.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease observe the chapter “EXERCISE
EXTREME CAUTION WHEN WORKING ON YOUR
VEHICLE” on Page 260.
