(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

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 windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.

arms should only be folded forward when
in the vertical position.
! Never open the hood when a 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.
