117Lights and windshield wipers Z

!
Vehicles with a rain sensor: if the wind-
shield becomes dirty in dry weather condi-
tions, the windshield wipers may be activa- ted inadvertently. This could then damage
the windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
Vehicles with a rain sensor: in the0062or
0063 position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the 0063position, the
rain sensor is more sensitive than in the 0062
position, causing the windshield wipers to
wipe more frequently.
If the wiper blades are worn, the windshield
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 windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have the wiper blades changed at a qualified
specialist workshop.
Changing the windshield wiper blades Removing the wiper blades
X Remove the SmartKey from the ignition
lock.
X Fold the wiper arm away from the wind-
shield. X
