intensity of the rain.
MWindshield wipers off
USlow intermittent wiping
Rain sensor operation with low
sensitivity.
VFast intermittent wiping
Rain sensor operation with high
sensitivity.
uSlow continuous wiping
tFast continuous wipingIntermittent 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
positionU orV.
!Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with wind-
shield washer fluid (
page 65).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.

For safety reasons, stop the vehicle in a safe
location and

remove SmartKey from starter switch
or

turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, starter switch is in
position0, same as with SmartKey
removed from starter switch)
before attempting to remove any blockage.

Remove blockage.

Turn the windshield wipers on again.If windshield wipers fail to function at all in the
combination switch positionU orV,

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 on an inter-
mittent setting when the vehicle is taken to an
automatic car wash or during windshield clean-
ing. 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.

65 Getting started

After the initial wipe, pauses between
wipes are automatically controlled by the

Warning!G

Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.

Steam from an overheated engine can
cause serious burns which can occur
just by opening the hood. Stay away
from the engine if you see or hear steam
coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
