Clear vision
in. WARNING
Wiper blades are crucial for safe driving! Only in good condition are they able to clear the windows properly to provide unrestricted
visibility. Worn or frayed wiper blades are a safety hazard!
=> page 69, "Replacing front wiper blades"
(D Note
In freezing or near freezing conditions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wiper on. Loosen a wiper blade which is frozen in
place before operating the wiper to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wiper to clear a frosted window . Using the wipers
as a convenient ice scraper will destroy the wiper blades.
[I) Tips
For better rearward vision when parking, the rear window wiper is
automatically activated one time when the windshield wipers are
switched on and reverse gear is engaged. •
Service position
Replacing the windshield wiper blades is only possible when
you move the wiper arms into the service position. In order to
use the windshield wipers, the hood must be completely
closed. When there is a risk of frost, make sure that the wiper
blades are not frozen to the windshield.
- Switch the ignition on. - Switch the
ignition off again and move the wiper lever
=:> page 65, fig. 62 from position Oto 1 within
10 seconds. The wiper arms now move into the field of
view in the windshield.
The service position can also be selected in the driver information
system*=>
page 22 .
(D Note
Never drive your vehicle when the windshield wiper arms are in the
service position and pulled away from the windshield. When you drive
faster than 4 mph (6 km/h) , the wiper arms automatically return
back to the park position and could cause paint damage to the engine
hood!
[I) Tips
• You can also turn on the service position, for example, if you want
to protect the windshield from icing by using a cover.
• The service position moves to
off automatically when you operate
the windshield wiper lever, or speed exceeds 4 mph (6 km/h). •
