Maintenance, Car Care
High-pressure cleaning units
Warning!
High-pressure cleaning units can damage
the following components:
–Tires
– Logos, emblems
– Painted surfaces
– Widened fenders
– Lock and latch of the removable towing attach-
ment
– Alternator, valve covers
– ParkAssist sensors
fPlease observe the operating instructions from
the unit manufacturer.
fAlways cover the lid over the brake fluid reser-
voir prior to cleaning. Never point the cleaning
jet directly at the lid.
fWhen cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 21 in.
(50 cm).fNever use high-pressure cleaning units with a
round-jet nozzle.
A high-pressure cleaning unit with round nozzle
will damage your vehicle. The tires are particu-
larly susceptible to damage.
fDo not point the cleaning jet directly at any of
the aforementioned components.
WashingThe best protection for the car from the damaging
effects of the environment is frequent washing and
preservation. The underside of the car should also
be thoroughly washed for cinders, salt or sanding
at winter‘s end.
The longer salt, road dust, industrial dust, insect
remains, bird excrement, and tree exudations (res-
in, pollen), etc. are allowed to remain on the body-
work, the more serious is their harmful effect.
New cars should be washed carefully with plenty
of clear water to protect the new paint work.
Dark paint finishes show up the smallest of sur-
face damage (e.g. scratches) more readily than
lighter colors.
Dark colors are also more susceptible to scratch-
ing because of the composition of their pigments
and require particularly careful paint care.fDo not wash your car in bright sunlight or while
the bodywork is still hot.
fWhen washing by hand, use abundant water, a
soft sponge or wash brush and Porsche car
shampoo.
fBegin by spraying the body thoroughly with wa-
ter to rinse away loose dirt.
fAfter washing, rinse the car with plenty of wa-
ter and then dry with a chamois leather.
Do not use the same chamois leather for
drying as you use for cleaning the windshield
and windows.
Warning!
Moisture which gets on to the brakes during
a car wash can reduce braking efficiency or
make the brake pull unevenly which could in-
crease the danger of an accident, causing
serious personal injuries or death.
fAlways apply the brakes a few times after
washing the car to test braking efficiency and
dry the brake discs.
When doing this, take care not to hamper other
road users behind you (traffic conditions per-mitting).
