Wiper Blades<br />
Maintenance notes<br />
Wiper blades that are in perfect condition are vital<br />
for a clear view.<br />
f Have the wiper blades replaced twice per<br />
year (before and after the cold season) or<br />
if wiper performance deteriorates or the<br />
blades are damaged.<br />
f Please see the chapter “CAR CARE<br />
INSTRUCTIONS” on page 269.<br />
Caution!<br />
Risk of damage if the wiper arm accidentally<br />
falls back onto the windshield.<br />
f Always hold the wiper arm securely when<br />
replacing the wiper blade.<br />
Risk of damage if wiper blades that are<br />
frozen in place are loosened improperly.<br />
f Thaw the wiper blades before loosening them.<br />
f Clean the wiper blades with window cleaner at<br />
regular intervals, especially after washing the<br />
vehicle in a car wash.<br />
We recommend Porsche window cleaner. If the<br />
wiper blades are very dirty (e.g. soiled with<br />
insect remains), they can be cleaned with<br />
a sponge or cloth.<br />
If the wiper blades rub or squeak, this may be due<br />
to the following:<br />
– If the vehicle is washed in an automatic<br />
car wash, wax residues may adhere to<br />
the windshield. These wax residues can<br />
be removed only by using window<br />
cleaner concentrate.<br />
– The wiper blades may be damaged or worn.<br />
f Have damaged wiper blades replaced<br />
immediately.<br />
f Please see the chapter “WASHER FLUID” on<br />
page 259.<br />
Contact your authorized Porsche dealer for<br />
more information.<br />
Replacing wiper blades<br />
f Please read the separate instructions provided<br />
by the wiper blade manufacturer.<br />
f We recommend that you have your authorized<br />
Porsche dealer to replace the wiper blades.<br />
Caution!<br />
Risk of damage. If a wiper blade is not<br />
changed properly, it can come loose when<br />
the car is moving.<br />
f Check whether the wiper blade is seated<br />
securely.<br />
The wiper blade must engage the wiper arm<br />
properly.<br />
