Rain sensor
This automatically adjusts the windscreen wiper timing to the intensity
of the rain during intermittent operation.
All functions controlled by the right hand lever are unaffected.
The rain sensor automatically activates when the right hand lever
is moved to AUTO, and it has a range of adjustment from "wiper
stationary", when the windscreen is dry, to "fast continuous operation",
with heavy rain.
To regulate the frequency of intermittent operation, with the lever on
the AUTO position, turn control C.
Turning the control clockwise, intermittent operation varies from
a maximum (fast intermittent operation) to a minimum (slow
intermittent operation).
N.B.: The rain sensor function is reset by turning the ignition key to position
0, and also by leaving the right-hand lever in the AUTO position. To
reactivate it, turn the selector switch to the OFF position and then again to
AUTO.
C
Before cleaning the front windscreen (for example in
service stations) make sure the rain sensor is deactivated
or that the key is turned to 0. The rain sensor must be
deactivated also when washing the vehicle by hand or in
automatic car washes.
In case of ice or snow on the front windscreen, do not activate the rain sensor
to avoid damaging the wiper motor or blades.
Rain sensor failure
In the event of a malfunction occurring when the rain sensor is active,
the wipers will be set to intermittent operation and the sensing range
will be set by the driver, whether there is rain on the windscreen or not.
In this case, we recommend that you deactivate the rain sensor and
turn on the wipers, if necessary, in continuous mode.
