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 252.

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.

Wiper Blades
Wiper blades that are in perfect condition are vital for a clear view.

  • Replace the wiper blades twice per year (before and after the cold season) or whenever wiper performance deteriorates or the blades are damaged.


Risk of damage when working on the wiper arm.

The windshield, wiper arm and blades can be damaged if the wiper arm accidentally falls back onto the windshield.

Wiper blades that are frozen in place can be damaged if they are loosened improperly.

  • Always hold the wiper arm securely when replacing the wiper blade.
  • Thaw the wiper blades before loosening them.

Information

  • Periodically clean the wiper blades with window cleaner, especially after the vehicle has been washed in a car wash.
    We recommend the Porsche window cleaner. If they are very dirty (e.g. with insect remains), they can be cleaned with a sponge or cloth.


If the wiper blades rub or squeak, this can be as a result of the following:
– If the vehicle is washed in an automatic car wash, wax residues may adhere to the windshield. These wax residues can
be removed only by using window cleaner concentrate.
– The wiper blades may be damaged or worn.

  • Replace damaged or worn wiper blades as soon as possible.
  • Please see the chapter "WASHER FLUID" on page 191.
  • Please contact your authorized Porsche dealer for further information.

Changing windshield wiper blades

  • Please read the separate instructions for fitting wiper blades as supplied by the manufacturer.
  • We recommend that you get your authorized Porsche dealer to replace the wiper blades.


Risk of damage.

If the wiper blades are not changed properly, they can come loose when the car is moving.

  • Check that the wiper blades are seated securely. The wiper blades must engage properly in the wiper arm.
