Windshield wipers
Switching the windshield wipers
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should always switch off
the windshield wipers in dry weather.

XTurn the co mbination switch to the corre-

In the Ä orÅ position, the appropriate
wipin g frequency isset automatically according
to the intensity of the rain. Inthe Å position,
the rain sensor ismore sensitive than inthe
Ä position, causing the windshield wiper to
wipe more frequently.
If the wiper blades are worn, the windshield will
no longer bewiped properly. This could prevent
you from observing the traff icconditions.
Replacing the wiper blades
