On vehicles without a rain sensor, the wipe intervals
of the windscreen wipers can be adjusted to
4 settings:

Adjusting rain sensor operation
For vehicles with a rain sensor, the amount of rain on
the windscreen is measured. The wipe interval is
automatically controlled accordingly.
Rain sensor operation is automatically activated at
speeds of less than approx. 4 km/h (2.5 mph) if the
windscreen wiper is switched on.
If a speed of approx. 8 km/h (5 mph) is exceeded,
the system switches to the preselected wiper
setting.

– If the wiper stalk is already in position 1 when the
ignition is switched on, the rain sensor is acti-
vated when the driving speed exceeds approx.
4 km/h (2.5 mph).
– If the wiper stalk is already in position 2 or 3
when the ignition is switched on, the windscreen
wipers remain switched off until the wiper stalk
is actuated.
Information
The wiper is stopped when the luggage compart-
ment lid is opened.
e To switch on the wipers again, move the wind-
screen wiper stalk upwards/downwards.
Adjusting the rain sensor sensitivity manually
The wiper speed can be set manually:
e Press switch A upwards – high sensitivity.
The setting is confirmed by one wipe of the
