Maintenance notes
f Periodically clean the wiper blades with a
window cleaner, especially after the vehicle

mend 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 adhere to the windscreen. These
wax residues can only be removed by using a
concentrated window cleaner.
f Please observe the chapter “WASHER FLUID”
on page 185.
Please contact your Porsche partner for further
information.
