Cleaning windows

  • Clean all windows regularly, inside and out, with window cleaner.
    We recommend Porsche window cleaner.
  • Do not use the same chamois for painted surfaces and for drying the windows.
    Preservative residues could reduce transparency.
  • Remove insect residues with insect remover.

The door windows have a water-repellent (hydrophobic) coating, which prevents soiling of the windows.

This coating is subject to natural wear and can be renewed.

  • Please contact an authorized Porsche dealer.

Care of windshield wiper blades
Windshield wiper blades that are in perfect condition are vital for a clear view.

  • Please see the chapter "WIPER BLADES" on page 204.
  • Have the wiper blades replaced twice per year (before and after the cold season) or if wiper performance deteriorates or the blades are damaged.
  • Clean the wiper blades with window cleaner at regular intervals, especially after washing the vehicle in a car wash.
    We recommend Porsche window cleaner.
    If wiper blades are very dirty (e.g. covered with insect remains), they can be cleaned with a sponge or cloth.

If the wiper blades judder or squeak, this may be due to 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.

  • Please see the chapter "WASHER FLUID" on page 203.
    – The wiper blades may be damaged or worn.
  • Have damaged wiper blades replaced immediately.

Repairing the underbody protection
The underside of your car is durably protected against chemical and mechanical influences.

As it is not possible to exclude the risk of damage to this protective coating in day to day driving, it is advisable to have the underside of the car inspected at certain intervals - preferably before the start of winter and again in spring - and the undercoating restored as necessary.

Your authorized Porsche dealer is familiar with the bodyseal treatment procedures and has the necessary equipment for applying factory approved materials. We recommend that you entrust them with such work and inspections.

Unlike conventional spray oils, undercoating and rust-proofing compounds based on bitumen or wax do not attack the sound-proofing materials applied at the factory.

Exhaust System Fire Risk

The exhaust system becomes very hot when the engine is running. Flammable material close to the exhaust system could ignite. Additional undercoating or rust protection agents on or near the exhaust system can become too hot when driving and ignite.

  • Do not apply additional undercoating or rustproofing on or near the exhaust manifold, exhaust pipes, catalytic converters or heat shields. During driving the substance used for undercoating could overheat and ignite.

  • Before applying fresh underseal, carefully remove deposits or dirt and grease. Once it has dried, the new undercoating compound forms a tough protective coating which provides efficient rust-proofing of the floor panels and components.
  • Always apply a fresh coating of suitable preservative to unprotect areas after cleaning the underside of the body, the transmission, the engine or carrying out repairs to underbody, engine or transmission components.

Effective rust-proofing is particularly important during the cold weather season. If your car is driven frequently in areas where salt has been spread on the roads, the whole engine compartment should be cleaned thoroughly after the winter to prevent salt from causing any lasting damage. A full under-body wash should also be performed at the same time.
