Maintenance note
f Periodically clean the wiper blades with a win-
dow cleaner, especially after the vehicle has
been washed in a car wash. We recommend
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 be adhering to the windshield.
These wax residues can only be removed by using
a window cleaner concentrate.
f Please see the chapter "WASHER FLUID" on
Page 218.
f Please contact your authorized Porsche dealer
for further information.
The wiper blades may be damaged or worn.
f Replace wiper blades as soon as possible.
