Maintenance and Car Care 235
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.
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.fDo 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.
fBefore 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.
fAlways 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 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.
Cleaning headlights, lights, interior and exterior plastic components, adhesive foils, reversing camera and radar sensor for adaptive cruise control
Observe the following points: fUse 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.fDo not spray water or interior window cleaner directly onto the plastic components in the passenger compartment, but first onto a sponge or cloth. Cleaning agents may, for example, enter controls or switches and cause damage.
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.fGently wipe the surface without applying too much pressure.fDo not clean when dry.
fNever use other chemical cleaners or solvents.fRinse cleaned surfaces with clear water.
Alloy wheels
Metal particles (e.g. brass or copper in brake dust) must not remain too long on alloy wheels.Contact corrosion can cause pitting.
Information
Cleaners with an oxide-removing effect or wrong pH value, as are commonly used for other metals, as well as mechanical tools and products, will damage the oxide layer and are therefore unsuitable.fUse only cleaners for alloy wheels (pH value 9.5). Products with the wrong pH value can destroy the protective layer on the wheels . We recommend Porsche cleaner for alloy rims.fIf possible, wash the wheels every two weeks with a sponge or washing brush. If the wheels are exposed to road salt, grit or industrial dust, weekly cleaning is necessary.fEvery three months, after cleaning, grease the wheels with car wax or an acid-free grease (e.g. Vaseline).Rub the grease in well with a soft cloth.fPlease see the chapter “CLEANING IN CAR WASHES” on page 233.
