Windscreen wipers
130
! 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.
Vehicles with a rain sensor: in the Ä or
Å position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the Å position, the
rain sensor is more sensitive than in the Ä
position, causing the windscreen wiper to
wipe more frequently.
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.

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/tailgate if a wiper
arm is folded away from the windscreen/
rear window.
Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen/
rear window.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release
the wiper arm without a wiper blade and it
falls onto the windscreen/rear window, the
windscreen/rear window may be damaged
by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
