Maintenance Note
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 wind-
shield. These wax residues can be removed
only by using window cleaner concentrate.
f Please see the chapter "WASHER FLUID" on
Page 260.
f Please contact your authorized Porsche dealer
for further information.
– The wiper blades may be damaged or worn.
f Replace damaged or worn wiper blades as
soon as possible.
