Windshield wipers
Switching the windshield wiper
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, alwaysu se
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should alwayss witch off
the windshield wipers in dry weather.

to low sensitivity)

î To wipe with washer fluid
XSwitchont he ignition.
XTurn the combination switch to the corre-
sponding position.
Vehicles with arain sensor: in theÄor
Å position, the appropriate wiping frequency
is automatically set accordingtot he intensity of
the rain. In the Åposition, the rain sensor is
more sensitive than in the Äposition, caus-
ing the windshield wiper to wipe more fre-
quently.
If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.
Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changin gthe wiper blades, you could
be trapped by the wiper arm. There is arisk of
injury.
Always switch off the windshield wipers and
ignition before changin gthe wiper blades.
!Never open the hood/tailgate if awiper arm
has been folded away from the windshield/
rear window.
Never fold awindshield wiper arm without a
wiper blade back ont othe windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
wiper arm without awiper blade and it falls
ont othe windshield/rear window, the wind-
shield/rear window may be damaged by the
force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at aqualified spe-
cialist workshop.
!To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
