IIntermittent wiping
IINormal wiper speed
IIIFast wiper speediThe intermittent wiping interval is
dependent on wetness of windshield.
After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.
!Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or
during windshield cleaning. Wipers will
operate in the presence of water
sprayed on the windshield, and wipers
may be damaged as a result.
The switch should not be left in
intermittent setting as the wipers will
wipe the windshield once every time
the engine is started. Dust that
accumulates on the windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a
dry windshield.

ers (leaves, snow, etc.), switch them off

Clean the sensors1 on the bumpers
using a mild car wash detergent, such
as Mercedes-Benz approved Car Sham-
poo, with plenty of water and a soft,
non-scratchy cloth.
When using a steam cleaner or power
washer, aim nozzle only briefly from a min-
imum distance of 12 in (30 cm) at
sensors1.Do not apply strong pressure to the sensor
cover, applying strong pressure may dam-
age the sensor cover.
To prevent scratches, never apply strong
force and only use a soft, non-scratchy
cloth when cleaning the sensor. Do not at-
tempt to wipe dirty sensors with a dry cloth
or sponge.Wiper blades
Fold wiper arm forward until it snapes

For safety reasons, switch off wipers and
remove SmartKey from starter switch
