Maintenance and Car Care

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.
f
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.
f
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.
f
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 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:
f
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.
f
Do 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.
f
Gently wipe the surface without applying too
much pressure.
f
Do not clean when dry.
f
Never use other chemical cleaners or
solvents.
f
Rinse 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.
f
Use 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.
f
If 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.
f
Every 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.
f
Please see the chapter “CLEANING IN CAR
WASHES” on page 233.
