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
– Seals of the electrically retractable ball hitch
– Alternator, valve covers
– ParkAssist sensors
f Please observe the operating instructions from
the unit manufacturer.
f Always cover the lid over the brake fluid reser-
voir prior to cleaning. Never point the cleaning
jet directly at the lid.
f When cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 21 in.
(50 cm).
f Never 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.
f Do not point the cleaning jet directly at any of
the aforementioned components.
Door lock
f To prevent the door lock from freezing during
the cold season, cover the lock barrel with a
suitable adhesive tape during washing.
Should the locks freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
Washing
The 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.
f Do not wash your car in bright sunlight or while
the bodywork is still hot.
f When washing by hand, use abundant water, a
soft sponge or wash brush and Porsche car
shampoo.
f Begin by spraying the body thoroughly with wa-
ter to rinse away loose dirt.
f After washing, rinse the car with plenty of wa-
ter and then dry with a chamois leather.
Do not use the same chamois leather for dry-
ing as you use for cleaning the windshield and
windows.
