IINormal wiper speed
IIIFast wiper speed
iTo signal minor directional changes such as
changing lanes, press the combination switch
only to the point of resistance and release. The
corresponding turn signals will flash three times.!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, al-
ways operate the windshield wipers with wind-
shield washer fluid (
page 57).

57 Getting started
Driving
Intermittent wiping
Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to
positionI.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.Single wipe
Press the combination switch briefly in
direction of arrow1 (
page 56) to
the resistance point.
The windshield wipers wipe one time
without washer fluid.Wiping with windshield washer fluid
Press the combination switch in direc-
tion of arrow1 (
page 56) past the
resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 330).
!Do not leave windshield wipers on an
intermittent setting when the vehicle is taken to
an automatic car wash or during windshield
cleaning. Windshield wipers will operate in the
presence of water sprayed on the windshield,
and windshield wipers may be damaged as a re-
sult.
!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.
iIntermittent wiping is interrupted when the
vehicle is at a standstill and a 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 gear selector lever is in position D or R
or

the wiper setting is changed using the com-
bination switch.
iTo prevent smears on the windshield, or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.


373 Operation
Vehicle care
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Make sure the vehicle’s on-board
electronics have status0 (
page 38).
Fold the wiper arms forward until they
snap into place.
Clean the wiper blade inserts with a
clean cloth and detergent solution.
Use a soft, clean cloth and a mild
window cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is
recommended.
!Do not apply strong pressure to the sensor
covers. Applying strong pressure may damage
the sensor covers.
Follow the instructions provided by the power
washer manufacturer on maintaining a distance
between the vehicle and the nozzle of the power
washer.
!To prevent scratches, never apply strong
force and only use a soft, non-scratching cloth
when cleaning the sensors. Do not attempt to
wipe dirty sensors with a dry cloth or sponge.
!Never open the hood when the wiper arms
are folded forward.
Warning!G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: Make sure the
vehicle's on-board electronics have
status0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.
!Do not pull on the wiper blade inserts. They
could tear.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO
start/stop button (vehicles with KEYLESS-GO*).
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the inside of
the front, rear or side windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.

Warning!G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: make sure the
vehicle’s on-board electronics have
status0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
Warning!G
Wiper blades are components that are sub-
ject to wear and tear. Replace the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the windows will not be
properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.
!Never open the hood when the wiper arms
are folded forward.
For your convenience, we recommend that you
have this work carried out at an authorized
Mercedes-Benz Center.
!Do not pull on the wiper blade inserts. They
could tear.
!Hold on to the wiper arm. If released, the
force of the impact from the tensioning spring
could crack the windshield.
