Maintenance and Car Care
Windows
The road dust which settles on the windshield and
windows contains particles of tire rubber and oil
residue. The interior trim and upholstery release
particles, particularly in strong sunlight, which col-
lect on the insides of the windows. These deposits
are augmented by impurities in the air which en-
ters the car through the fresh air vents.
f Clean all windows regularly, inside and outside,
with Porsche window cleaner.
f Make sure not to damage the TV antenna in the
side window when cleaning.
f If you use a chamois leather for the windows,
do not use it for paintwork as it will otherwise
pick up a certain amount of preservative or
polish and could smear the windows and thus
impair vision.
f Remove dead insects with insect remover.
Care of wiper blades
Wiper blades that are in perfect condition are vital
for a clear view.
f Replace the wiper blades twice per year
(before and after the cold season) or if wiper
performance deteriorates or the blades are
damaged.
f
Please observe the chapter “WIPER BLADES”
on Page 295.
f
Periodically clean the wiper blades with
window cleaner, especially after the vehicle
has been washed in a car wash.
We recommend the Porsche window cleaner.
In the event of heavy soiling (e.g. insect
residue), the blades can be cleaned with a
sponge or a cloth. If the wiper blades rub or
squeak, this may have the following causes:
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.
f Please observe the chapter “WASHER FLUID”
on Page 292.
f Please contact your authorized Porsche dealer
for further information.
Undercoating
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 in-
spected at certain intervals - preferably before the
start of winter and again in spring - and the under-
coating restored as necessary.
Your authorized Porsche dealer is familiar with the
bodyseal treatment procedures and has the nec-
essary 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 ap-
plied at the factory.
Warning!
Danger of fire resulting in serious personal
injury or death.
f Do not apply additional undercoating or rust-
proofing on or near the exhaust manifold, ex-
haust pipes, catalytic converters or heat
shields. During driving the substance used for
undercoating could overheat and ignite.
Effective rust-proofing is particularly important du-
ring the cold weather season. If your car is driven
frequently in areas where salt has been spread on
