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. If
they are very dirty (e.g. with insect remains),
they can be cleaned with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
– If the vehicle is washed in an automatic car
wash, wax residues may adhere to the
windscreen. These wax residues can be
removed only by using window cleaner concen-
trate.
f Please observe the chapter "ADDING WASHER
FLUID" on Page 267.
Please contact your Porsche partner for further
information.
– The wiper blades may be damaged or worn.
f Replace damaged wiper blades as soon as
possible.
