ments.
Windshield wipers
The combination switch is located on the
left of the steering column.Combination switch1Single wipe
Wiping with windshield washer fluid
2Switching on windshield wipers
Switch on the ignition (
page 38).
i
To signal minor directional changes such as
changing lanes, press combination switch only
to point of resistance and release. The corre-
sponding turn signals will flash three times.
!
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 58).
!
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 and
open the driver’s door (with the driver’s
door open, starter switch is in
position0, same as with SmartKey re-
moved from starter switch)
before attempting to remove any blockage.
Remove blockage.
Turn the windshield wipers on again.
57 Getting started
Driving
Switching on windshield wipers
Turn the combination switch to the de-
sired position depending on the inten-
sity of the rain.
MWindshield wipers off
USlow intermittent wiping
Rain sensor operation with low
sensitivity.
VFast intermittent wiping
Rain sensor operation with high

uSlow continuous wiping
tFast continuous wipingIntermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to
positionU or V.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
!
If windshield wipers fail to function at all in
combination switch positionU or V,
set the combination switch to the next high-
est wiper speed
have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center
!
Do not leave windshield wipers in
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.
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 positionD orR
or
the wiper setting is changed using the com-
bination switch
58 Getting startedDrivingSingle 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
Push 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 292).
Problems while driving
The engine runs erratically and misfires
An ignition cable may be damaged.
The engine electronics may not be
operating properly.
Unburned gasoline may have entered
the catalytic converter and damaged it.
Give very little gas.
Have the problem repaired by an
authorized Mercedes-Benz Center as
soon as possible.
The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.
Stop the vehicle in a safe location as
soon as possible and turn off the en-
gine. Allow engine and coolant to cool
off.
Check the coolant level and add cool-
ant if necessary (
page 290).
In case of accident
If the vehicle is leaking fuel:
Do not start the engine under any
circumstances.
Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be
determined:
Notify an authorized Mercedes-Benz
Center.
If no damage can be determined on the
major assemblies
fuel system
engine mount:
Start the engine in the usual manner.
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.
337 Operation
Vehicle care
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Switch on the ignition (
page 38).
Turn combination switch to wiper
settingu (
page 57).
With wiper arms in vertical position,
switch off the ignition (
page 60).
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.
!
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.
!
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.!
Do not pull on the wiper blade inserts. They
could tear.

With wiper arms in the vertical position,
turn SmartKey in the starter switch to

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 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.
!
Never open the hood when the wiper arms
are 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 windshield.
Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
!
To avoid damage to the hood the wiper arms
should only be folded forward when in the verti-
cal position.
