Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
When you select intermittent wiping, the
rain sensor is activated. The rain sensor
automatically sets a suitable wiping
interval depending on the wetness of the
sensor surface.
!
Do not leave windshield wipers in intermit-
tent setting when the vehicle is taken to an auto-
matic car wash or during windshield cleaning.
Wipers will operate in the presence of water
sprayed on the windshield, and windshield
wipers may be damaged as a result.
!
If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
Turn the combination switch to
position U or V.
Getting started
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
i
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when
all doors are closed
and
the automatic transmission is set to
position D or R
or
the wiper setting is changed using the
combination switch
Single wipe
