Replacing wiper blades
Replacing wiper blades
Placing wiper arms in vertical positionWiper blades in vertical position
Make sure the hood is fully closed.
Vehicles with SmartKey

Turn SmartKey in starter switch
position1.

Turn combination switch to wiper
settingu (
page 408).

With wiper arm in vertical position, turn
the SmartKey in starter switch to
position0.
Warning!
G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have
status0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury. Warning!
G
Wiper blades are components that are sub-
ject to wear and tear. Replace the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the front window will not
be properly wiped. As a result, you may not
be able to observe surrounding traffic condi-
tions and could cause an accident.
!
To avoid damage to the hood:


The wiper arms should only be folded for-
ward when in the vertical position.


Never open the hood when the wiper arm is
folded forward.
!
Hold on to the wiper when folding the wiper
arm back. If released, the force of the impact
from the tensioning spring could crack the wind-
shield.
Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
