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.
Turn the combination switch to 
position
U or V.
After the initial wipe, pauses between 
wipes are automatically controlled by the 
rain sensor.
Single wipe
Press the combination switch briefly in 
direction of arrow
1 to the resistance 
point.
The windshield wipers wipe one time 
without washer fluid.
Remove blockage.
Turn the windshield wipers on again.
If windshield wipers fail to function at all in 
combination switch position
U or V,
set the combination switch to the next 
higher wiper speed
have the windshield wipers checked at the 
nearest authorized Mercedes-Benz Light 
Truck Center
!
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.
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
