Rain sensor (option)
The rain sensor automatically activates the
windscreen wipers based on how much wa-
ter it detects on the windscreen. The sensitiv-
ity of the rain sensor can be adjusted using
the thumbwheel (1), see the illustration
page 55.
Thumbwheel
Use the thumbwheel to adjust the frequency
of sweeps when intermittent wiping is select-
ed, or the sensitivity to rain when the rain
sensor is selected.
– Turn the thumbwheel clockwise for higher
sensitivity and anticlockwise for lower
sensitivity. (An extra sweep is made when
the thumbwheel is turned clockwise.)
On/Off
When activating the rain sensor, the ignition
key must be in position I or II and the wind-
screen wiper stalk switch must be in
position 0.
To activate the rain sensor:
– Press the button (B). A light in the button
illuminates to indicate that the rain sensor
is active.
To turn the rain sensor off, either:
– Press the button (2).
– Press the stalk switch downward to anoth-
er wiper programme. If the stalk switch is
raised, the rain sensor will remain active,
the wipers make an extra sweep and then
return to rain sensor mode when the stalk
switch is released back to position 0.
The rain sensor is automatically deactivated
when the key is removed from the ignition
switch or five minutes after the ignition is
switched off.
IMPORTANT
In an automatic car wash: Turn off the rain
sensor by pressing the button (B) while the
ignition key is in position I or II . Otherwise,
the windscreen wipers may start and be
damaged.
