Safety notes
G
Warning!
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
(vehicles 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.
G
Warning!
Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windows will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
!
Never open the hood when a front wiper
arm is folded forward.
Hold on to the wiper when folding a wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield or the rear window.
Do not allow a wiper arm to contact the
windshield glass or the rear window
without a wiper blade inserted.
Mercedes-Benz recommends that you have
this work carried out at an authorized
Mercedes-Benz Center.
