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