headlamp setting checked regularly. Windscreen wipers
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 collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen 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
windscreen with washer fluid after an auto-
matic car wash. Windscreen wipers

!
Vehicles with a rain sensor: if the wind-
screen becomes dirty in dry weather con-
ditions, the windscreen wipers may be acti- vated 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

B í Single wipe/î to wipe the wind-
screen using washer fluid
X Switch on the power supply with the Start/
Stop button or the key (Y page 161).
X Turn the combination switch to the corre-
sponding position.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord- ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wipers to wipe more frequently.
The washer fluid is fed through the wiper
blades; when the screen is wiped with washer
fluid î, the water is emitted directly from
the blades.
If you push the combination switch beyond
the point of resistance in the direction of
arrow Band hold it in this position, the man- ual wash programme is activated. If you
briefly push the combination switch beyond
the point of resistance in the direction of
arrow B, the automatic wash programme is
activated.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions. 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.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet if a windscreen
wiper arm has been folded away from 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
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
! Always position the windscreen wiper
arms vertically before folding them away
from the windscreen. By doing so, you will
avoid damage to the bonnet. 134
