Instruments and controls
Right-hand stalk switch
Rain sensor (option)
The rain sensor automatically activates the
windscreen wipers based on how much
water it detects on the windscreen. The
sensitivity of the rain sensor can be adjusted
using the thumbwheel (C).
Turn the thumbwheel clockwise to increase
sensitivity or anticlockwise to decrease sensi-
tivity, (there is an extra swipe 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
windscreen wiper stalk switch must be in
position 0.

To activate the rain sensor:
– press the button (B). An LED in the
button comes on to indicate that the rain
sensor is active.
To turn the rain sensor off, either:
– press button (B).
– press the stalk switch downward to
another wiper program. 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 is released 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!
At an automatic car wash:
Deactivate the rain sensor by pressing
the button (B) while the ignition key is in
position I or II. Otherwise, the
windscreen wipers could start swiping
and become damaged.
Thumbwheel
Use the thumbwheel to adjust the frequency
of sweeps when intermittent wiping is
selected, or the sensitivity to rain when the
rain sensor is selected.
