Always switch off the windshield wipers and
ignition before changing the wiper blades.

Never open the hood/tailgate if a wiper arm
has been folded away from the windshield/
rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
wiper arm without a wiper blade and it falls
onto the windshield/rear window, the wind-
shield/rear window may be damaged by the

Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.

To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
