Power Steering

No Power Steering Assist

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.

  • Exercise great care when being towed.
  • Have the fault remedied at your nearest authorized Porsche dealer.

The flow noise heard at full steering lock is system related and does not indicate a defect in the steering system.

Checking hydraulic fluid

  • Please see the chapter "EXERCISE EXTREME CAUTION WHEN WORKING ON YOUR VEHICLE" on page 170.

The hydraulic fluid reservoir is located in the engine compartment.

Regular checking of hydraulic fluid is part of servicing.

Air Filter
A dirty air filter not only reduces engine performance, but can lead to premature engine wear. Regular filter replacement is part of the routine maintenance service.

  • In dusty conditions, check the filter element more frequently and replace if necessary.

Combination Filter
The fresh air passing through the combination filter into the passenger compartment is virtually free of dust, pollen, and unpleasant odors.

  • If the outside air is polluted by exhaust fumes, press the circulating-air button.

A dirty filter can be the cause of reduced air flow:

  • Have filter replaced by your authorized Porsche dealer.

Regular filter replacement is part of the routine maintenance service.

Fluids/Oils for Manual Transmission and Porsche Doppelkupplung (PDK)
The transmission fluids/oils have to be checked and changed at the intervals listed in your Maintenance Schedule.

  • Please see the chapter "CAPACITIES" on page 245.

Do not tow the car or run the engine without fluid/ oil in the transmission. The transmission may be damaged by even a tiny speck of dirt, only a clean funnel or spout must be used when adding fluid/ oil.

We recommend that you have the fluids/oils changed at your Porsche dealer, who has the required lubricants and the necessary filling equipment.

  • If you suspect an oil leak in the transmission, have your authorized Porsche dealer check it out immediately.
