!
Do not operate the wipers when the
windshield/rear window is dry. Dust that
accumulates on a windshield/rear window
might scratch the glass and/or damage the
wiper blades when wiping occurs on a dry
windshield/rear window. If it is necessary
to operate the wipers in dry weather
conditions, always operate the wipers with
washer fluid.

to the desired position,
depending on the intensity of the rain.
Only switch on intermittent wiping under wet
weather conditions or in the presence of
precipitation.
When you select intermittent wiping, the rain
sensor is activated. The rain sensor sets a
suitable wiping interval depending on the
wetness of the sensor surface automatically.
!
Do not leave windshield wipers on an
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.
!
If you have set intermittent wiping, dirt on
the surface of the rain 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.

After the initial wipe, pauses between
wipes are controlled by the rain sensor
automatically.
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or
out of the vehicle from being sprayed.
