Wipers

Notes
! Do not operate the 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 wipers in dry weather
conditions, always operate the wipers with
washer fluid.

Intermittent wiping

Only switch on intermittent wiping under wet
weather conditions or in the presence of
precipitation.
Y page 95).
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.
Intermittent wiping interval is dependent on
the wetness of the windshield. After the initial
wipe, pauses between wipes are controlled by
the rain sensor automatically.
X
Turn the combination switch to position I.
Intermittent wiping is interrupted when the
vehicle is at a standstill and a door is opened.
This protects persons getting into or out of
the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and
the automatic transmission is in drive

position D or reverse gear R
