!
If the windshield wipers leave smears on the
windshield after the car has been driven through
an automatic car wash, then wax or other resi-
due is on the windshield. Shortly after washing
the car in an automatic car wash, clean the wind-
shield with windshield washer fluid
(
page 352).
!
Do not operate the wipers when the wind-
shield is dry. Dust that accumulates on a wind-
shield might scratch the glass and/or damage
the wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate the wip-
ers in dry weather conditions, always operate
the wipers with windshield washer fluid
(
page 352).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.


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

turn off the engine by turning the
SmartKey to position0 and withdraw
SmartKey from starter switch
or


turn off the engine by pressing the
KEYLESS-GO* start/stop button
(page 317) 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 the windshield wipers fail to function at all in
combination switch position u,


set the combination switch to the next high-
er wiper speed


have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center

352 Controls in detailWindshield wipersIntermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
Set the wiper switch to position U
or V.The wipers move across the wind-
shield. Afterward, the wiping intervals
are determined by the wetness of the
windshield.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
Single wipe
Press the combination switch briefly in
the direction of arrow2.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid
Press the combination switch in the di-
rection of arrow2 past the resistance
point.
The windshield wiper operates with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 498).
i
When the windshield wipers are switched on
and you brake the vehicle to a stop, the wipers
operate more slowly.
!
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 wip-
ers 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 trans-
mission is set to positionD orR
or


the wiper setting is changed using the com-
bination switch
i
To prevent smears on the windshield, wipe
with windshield washer fluid every now and then
even when it is raining.

on the windshield.

Replace windshield wiper blades
(page 627).
The area of the windshield within the cam-
era’s field of view is dirty.

Clean windshield (
page 539).
The area of the windshield within the cam-
era’s field of view has been damaged.

Replace windshield.
The area of the windshield within the cam-
era’s field of view is fogged over.

Remove condensation (
page 539).
The area of the windshield within the cam-
era’s field of view is iced over.

Defrost windshield (
page 429).

540 OperationVehicle careCleaning the windows and the wiper
blades
Make sure the hood is fully closed.

Place wiper arms in vertical position
(page 627).

Make sure the vehicle’s on-board elec-
tronics have status 0 (
page 315).

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 win-
dow cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is recom-
mended.
!
If the windshield wipers leave smears on the
windshield after the vehicle has been driven
through an automatic car wash, wax or other res-
idue is on the windshield. Clean the windshield
with washer fluid shortly after cleaning the car in
an automatic car wash (
page 352).
!
The windshield wipers must be in a vertical
position before folding them away from the wind-
shield. They could otherwise damage the hood.
Never open the hood when the wiper arms are
folded forward.
Warning!
G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles 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.!
While doing so, only touch the wiper arm so
as not to damage the wiper blade inserts.
!
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 con-
taining 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.

G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles 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. Change 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.
!
To avoid damage to the hood:


The wiper arms should only be folded for-
ward when in the vertical position.


Never open the hood when the wiper arm is
folded forward.
!
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 wind-
shield.
Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.
Make certain that the wiper blades are properly
installed. Improperly installed wiper blades may
cause windshield damage.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
