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 rust-proofing 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.

Cleaning headlights, lights, interior and exterior plastic components, adhesive films, radar sensor for adaptive cruise control and rearview camera

Observe the following points:

• Use only clean water and a little dishwashing liquid or interior window cleaner to clean headlights, lights, plastic components and surfaces.
  Use a soft sponge or a soft, lint-free cloth.
• Do not spray water or interior window cleaner directly onto plastic parts in the passenger compartment. Spray onto a sponge or cloth first. Cleaning agents could penetrate into controls or switches, for example, and damage them.

Information
An interior window cleaner can also be used to clean plastic surfaces (always read the cleaning instructions on the container!).

We recommend Porsche interior window cleaner.

• Gently wipe the surface without applying too much pressure.
• Do not clean when dry.
• Never use other chemical cleaners or solvents.
• Rinse cleaned surfaces with clear water.
