Headlamp cleaning system*
The headlamps are automatically cleaned
with a high-pressure water jet when, at the
same time,

the engine is running

the headlamps are switched on

the windshield wipers have wiped the
windshield with washer fluid for the
first time.
The headlamps are cleaned every tenth
time the windshield is washed with washer
fluid.
When you switch off the headlamps or the
ignition, the automatic function is reset
and will start counting the next time from
the beginning.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 330).Corner-illuminating front fog lamps*
(With Bi-Xenon* headlamps only)
The corner-illuminating front fog lamps
improve illumination of the area in the
direction into which you are turning.
The corner-illuminating front fog lamps will
operate with the engine running and with:

the exterior lamp switch in
positionB or* (
page 108)
or

the daytime running lamp mode acti-
vated (
page 110).
iThe corner-illuminating front fog lamps will
only come on in low ambient lighting conditions.
iIf you are driving faster than 25 mph
(40 km/h) or have the front fog lamps switched
on, the corner-illuminating front fog lamps
function is not available.

Wiping with windshield washer fluid
Switch on the ignition.
!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.
!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.
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.

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

remove the 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)

engage the parking brake
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 or V,

set the combination switch to the next
higher wiper speed

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

tFast continuous wiping
Single wipe
Press the combination switch briefly in
the direction of arrow2 (
page 117)
to the resistance point.
The windshield wipers wipe one time
without washer fluid.
Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
iWhen the windshield wipers are switched on
and you brake the vehicle to a stop, the wipers
operate more slowly.
!Vehicles with 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 the windshield wipers may
be damaged as a result.
!Vehicles with rain sensor*:
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 undes-
ired fashion. This could then damage the wind-
shield wiper blades or scratch the windows. You
should therefore switch off the windshield wip-
ers when weather conditions are dry.

119 Controls in detail
Windshield wipers
Turn the combination switch to posi-
tion U or V.
Intermittent wiping starts with selected
wiping interval.
Vehicles with rain sensor*:
After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.
Intermittent wiping interval is depen-
dent on wetness of windshield.Wiping with windshield washer fluid
Press the combination switch in the di-
rection of arrow2 (
page 117) 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 330).
iIntermittent 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 clutch pedal is depressed (vehicles with
manual transmission
or

the gear selector lever is positionD orR (ve-
hicles with automatic transmission*)
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.
iVehicles with headlamp cleaning system*:
The headlamp cleaning system* will clean the
headlamps automatically after the first and every
tenth time windshield washer fluid is used while
the engine is running (
page 112).
