Cleaning headlights, lights, interior and
exterior plastic parts, adhesive films
Observe the following points:
f Use only clean water and a little dishwashing
detergent or interior window cleaner to clean
headlights, lights, plastic parts and surfaces.
Use a soft sponge or a soft, lint-free cloth.
Note
An interior window cleaner can also be used to
clean plastic surfaces (observe cleaning instruc-
tions on the container!).
We recommend the 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.
Light alloy wheels
Metal particles (such as brass or copper in brake
dust) must not remain too long on a light alloy
wheel.
Contact corrosion can cause pitting.
Note
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 unsuit-
able.
f Use only cleaners for light 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 light alloy
rims.
f If possible, wash the wheels every two weeks
with a sponge or washing brush. Where there
is 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 For information on cleaning the light alloy
wheels in car washes:
Please observe the chapter "CLEANING IN CAR
WASHES" on Page 276.
Warning!
Danger of accident if cleaning agents
(e.g. wheel cleaning agents) come into
contact with the brake discs. The resulting
film on the brake discs can impair braking
performance.
f Make sure that no cleaning agent comes into
contact with the brake discs.
f If cleaning agent has come into contact with
the brake discs, thoroughly clean the brake
discs with a strong jet of water.
f Paying attention to any road users behind you,
dry the brake discs by applying the brakes.
Stainless steel exhaust tailpipes
Stainless steel exhaust tailpipes can discolour due
to soiling, strong heat, and combustion residues.
The original polish can be achieved again using
commercially available metal polishing paste or
metal polish.
