Power Steering
Warning!
Risk of accident resulting in serious personal
injury or death. When the engine is stationary
(e.g. when on tow) or the hydraulic system
fails, there is no assistance for steering.
Therefore, substantially more force will have
to be exerted.
f Exercise great care when on tow.
f Have 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 defect in the steer-
ing system.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
f Please observe the chapter “EXERCISE
EXTREME CAUTION WHEN WORKING ON YOUR
VEHICLE” on Page 282.
