Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid. !
If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. 1

Vehicles with a rain sensor: in theÅor
Ä position, the appropriate wiping frequency
is automatically set according to the intensity of
the rain. In the Åposition, the rain sensor is
more sensitive than in the Äposition, caus-
ing the windscreen wiper to wipe more fre-
quently.
If the wiper blades are worn, the windscreen will no longer be wiped properly. This could mean
you are unable to observe the traffic conditions. Windscreen wipers

Replacing the wiper blades
Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without a
wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release the
windscreen wiper arm without a wiper blade
and it falls onto the windscreen, the wind-
screen may be damaged by the force of the
impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
