To signal minor directional changes, such as
changing lanes, press combination switch to
point of resistance only and release. The corre-
sponding 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
wipers in dry weather conditions, always operate
the windshield wipers with windshield washer
fluid (page 53).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.


For safety reasons, stop the vehicle in a safe
location, remove the SmartKey from starter
switch before attempting to remove any
blockage.


The hood must be opened (
page 250) be-
fore folding the wiper arms away from the
windshield. You could otherwise damage the
hood and/or the wiper arm.


Remove the blockage.


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


set the combination switch to the next
highest wiper speed


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

53 Getting started
Driving
Intermittent wiping
The intermittent wiping interval is depen-
dent on the wetness of the windshield. 
Turn the combination switch in direc-
tion of arrow 2 to positionI.
After the initial wipe, pauses between
wipes are controlled by the rain sensor.Single wipe

Press combination switch briefly in
direction of arrow1 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Press combination switch in direction
of arrow1 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 257).
!
Do not leave windshield wipers on an
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.
!
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 gear selector
lever is in drive positionD or reverse gearR
or


the wiper setting is changed using the com-
bination switch
i
To 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.

299 Operation
Vehicle care
Power washer
Cleaning the windows and wiper blades

Remove the SmartKey from the starter
switch.

Fold the wiper arm away from the
windshield (
page 363).
You must feel the wiper arm engage in
position.

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
recommended.
!
Make sure that the windshield wiper switch
is set to0 (
page 52). Otherwise, the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 299). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
!
Do not use power washer to clean your
vehicle or the engine.
!
The hood must be opened (
page 250) be-
fore folding the wiper arm away from the wind-
shield. You could otherwise damage the hood
and/or the wiper arms.
!
Never open or close the hood when the wip-
er arms are folded away from the windshield.
You could otherwise damage the hood and/or
the wiper arm.
Warning!
G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
before cleaning 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.
!
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 door windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.

Replacing wiper blades
Removing wiper blades

Remove the SmartKey from starter
switch.

starter switch before replacing a wiper
blade. Otherwise the 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.!
The hood must be opened (
page 250)
before folding the wiper arms away from the
windshield. You could otherwise damage the
hood and/or the wiper arm.
!
Do not pull on the wiper blade inserts. They
could tear.

364 Practical hintsReplacing wiper bladesInstalling wiper blades 
Position the wiper blade at 90° to the
wiper arm.

Slide the wiper blade onto the wiper
arm.

Fold the wiper blade parallel to the
wiper arm.

Fold the wiper arm backward to rest on
the windshield. Make sure you hold on
to the wiper when folding the wiper arm
back.
!
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.
Do not allow the wiper arms to contact the
windshield glass without a wiper blade inserted.
Make sure 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.
