Replacing Wiper Blades - Mercedes-Benz 2009 R-Class Operator's Manual

Replacing wiper blades

Safety notes
G Warning!
For safety reasons, switch off wipers and
remove SmartKey from 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
properly wiped. 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.
