Wet brakes
WARNING
Reduced or uneven braking action may be caused
by wet brakes.
f
After washing the vehicle, test the brakes and
steering and briefly brake the disks dry.
When doing so, make sure that vehicles
traveling behind you are not affected.
Cleaning in car washes
Optional add-on parts or parts that project beyond
the contours of the vehicle may be damaged by
design features of car washes.
The following parts are particularly at risk:
– Windshield wipers and rear wiper (always
switch them off – wiper stalk in position 0 –
to prevent them wiping unintentionally in
sensor operation).
– Exterior mirrors (always fold in).
– External antenna (always unscrew).
– Spoiler.
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage).
– High-gloss wheels (to prevent these from
getting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
f
Please consult the operator before using
automatic car washes.
f
All parts not reached by a car wash, such as
door and lid seams or door sills, must be
washed and polished by hand.

Maintenance and Car Care
Information
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.
Paint care
In order to protect the paint on your vehicle in the
best possible way against mechanical and
chemical damage, you should
– preserve it regularly,
– polish it if necessary,
– remove spots and stains, and
– repair damaged paintwork.
f
Do not apply care products containing silicone
to the windows.
Information
f
Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage the
paintwork.
f
Do not treat matt-painted components with
preservatives or polishes as these remove the
matt effect.
Preservation
The paint surface becomes dull over time due to
weathering.
f
Preserve paint regularly.
f
Apply paint preservative after washing the
vehicle and polish it smooth to preserve the
paintwork.
This keeps the paint shiny and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating the
paint.
Polishing
Only when the original shine can no longer be
obtained using preservatives should paint polish
be used to clean the paint.
We recommend Porsche paint polish.
Removing spots and stains
f
Remove tar spatters, traces of oil, insects etc.
as soon as possible using an insect remover,
as they discolor the paint if left to work on it
over time.
f
Wash the treated areas carefully afterwards.
Repairing minor paint damage
f
Have minor paint damage (cracks, scratches
or stone damage) repaired immediately
before corrosion begins.
Please contact an authorized Porsche dealer.
If traces of corrosion have already formed, these
must be thoroughly removed. An anti-corrosion
primer must then be applied to these spots,
followed by top-coat paint.
Paint data can be found on the vehicle data
carrier.

IDENTIFICATION NUMBER" on page 218.
