! Vehicles with a rain sensor: if the
windshield becomes dirty in dry weather
conditions, the windshield wipers may be
activated inadvertently. This could then
damage the windshield wiper blades or
scratch the windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
Vehicles with a rain sensor: in the Ä or
Å position, the appropriate wiping
frequency is automatically set according to
the intensity of the rain. In the Å position,
the rain sensor is more sensitive than in
the Ä position, causing the windshield
wipers to wipe more frequently.
Intermittent wiping is interrupted when you
stop the vehicle and open a front door. This
prevents a person from being splashed
inadvertently when getting into or out of the
vehicle.
Intermittent wiping continues when all doors
are closed and
Ryou shift AUTOTRONIC to drive position D
or reverse gear R
or
Ryou change the wipe setting on the
combination switch.
iTo prevent smearing on the windshield or
noise when wiping, wipe the windshield
occasionally with washer fluid.
