Wiper blades that are in perfect condition are vital for a clear view.
Please see the chapter "WIPER BLADES" on page 184.
Replace the wiper blades twice per year (before and after the cold season) or whenever wiper performance deteriorates or the blades are damaged.
Periodically clean the wiper blades with Porsche window cleaner, especially after the vehicle has been washed in a car wash.
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, 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 immediately.
Please see the chapter "WASHER FLUID" on page 182.
Please contact your authorized Porsche dealer for further information.
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 any deposits of 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 unprotected areas after cleaning the underside of the body, the transmission, the engine or carrying out repairs to under-body, 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.
Stainless steel exhaust tailpipes
Stainless steel exhaust tailpipes can discolor due to soiling, strong heat, and combustion residues. The original polish can be achieved again using commercially available metal polishing paste or metal polish.
