! Do not operate the windshield wipers
when the windshield is dry. Dust that
accumulates on a windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate
the windshield wipers in dry weather
conditions, always operate the
windshield wipers with windshield
washer fluid.
! If anything blocks the windshield
wipers (leaves, snow, etc.), switch them
off immediately.
For safety reasons, stop the vehicle in a
safe location and

Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers
will operate in the presence of water
sprayed on the windshield, and
windshield wipers may be damaged as a
result.
! Vehicles with rain-light sensor*:
If you have set intermittent wiping, dirt
on the surface of the sensor or optical
effects may cause the windshield wipers
to wipe in an undesired fashion. This
could then damage the windshield wiper
blades or scratch the windshield. You
should therefore switch off the
windshield wipers when weather
conditions are dry.
