Replacing Wiper Blades - Mercedes-Benz S 450 4MATIC Operator's Manual

Replacing wiper blades

Warning!
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
status 0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
Warning!
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:
G
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.
G
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
