Activation
The sensor is activated when the ring nut A fig. 46 is
turned to
position: the windscreen wiper stroke
frequency is thus adjusted in accordance with the
amount of water on the windscreen.
The activation of the sensor is signalled by a "stroke"
to show that the command has been acquired.
The sensitivity of the rain sensor can be adjusted
through the Setup menu (see paragraph "Menu
Items" in this section).
The variation in sensitivity during rain sensor
operation is also signalled by a stroke of the wipers.
This stroke is also executed with the windscreen dry.
IMPORTANT Keep the glass in the sensor area
clean.
If the windscreen washer is used with the rain sensor
activated, the normal washing cycle is performed,
after which the rain sensor resumes its normal
automatic operation.
Deactivation
Move the stalk ring nut away from the position
or turn the ignition key to STOP.
If the ignition key is turned to the STOP position
leaving the ring nut A in position
, no wiping
cycle is performed at the next startup (ignition key
to the MAR-ON position) even in case of rain.
This prevents unwanted activation of the rain sensor
when the engine is started (i.e. when the windscreen
is being washed by hand or the wipers are stuck to
the windscreen by ice).
To restore automatic operation of the rain sensor,
turn ring nut A from
position to position and
then turn the ring nut back to the position.
When the rain sensor is reactivated using any of the
manoeuvres described above, reactivation is
indicated by a single stroke of the windscreen wipers,
regardless of the condition of the windscreen.
In the event of malfunction of the rain sensor whilst
it is active, the windscreen wiper operates
intermittently at a speed consistent with the
sensitivity setting of the rain sensor, regardless of
whether there is rain on the glass (on some versions
sensor failure is indicated on the display).
The sensor continues to operate and it is possible to
set the windscreen wiper to continuous mode (1
st
or 2
nd
speed). The failure indication remains for
as long as the sensor is active.
The rain sensor is able to recognise, and
automatically adjust itself in the presence of the
following conditions:
❒
presence of dirt on the controlled surface (salt,
dirt, etc.);
❒
presence of streaks of water caused by the worn
window wiper blades;
❒
difference between day and night.
Do not activate the rain sensor when
washing the car in an automatic car wash.
