The sensor has an adjustment range
which varies progressively from wiper
still (no stroke) when the windscreen is
dry, to wiper at 2nd continuous speed
(fast continuous operation) with intense
rain.
Activation
8) 9)
Turn the ring fig. 57 to position
activate the rain sensor.
Activation of the sensor is signalled by
a flick of the wiper, which indicates that
the command has been acquired.
The variation in sensitivity during rain
sensor operation is also signalled by a
flick of the wiper (command acquired
and implemented). This stroke is also
executed with the windscreen dry.
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.
WARNING Keep the glass in the sensor
area clean.

ring turned to the or position,
wiping operates automatically and is
disabled when the outside temperature
is below 0°C.

Deactivation
Use ring fig. 57 or turn the ignition device
to STOP.
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, while sensor
or to
failure is indicated on the display.
The sensor continues to operate and it
is possible to set the windscreen wiper
to continuous mode
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 (e.g. salt, dirt, etc.)
presence of streaks of water caused
by the worn window wiper blades;
difference between day and night.
22)
REAR WINDOW WIPER/WASHER
Engaging reverse gear with the
windscreen wiper operating activates a
single cycle of the rear window wiper.
Moving the stalk fig. 57 (it only has
unstable positions):
towards the instrument panel
activates the rear window washer
(a brief push activates one washing
cycle, keeping the stalk pushed washes
continuously until the stalk is released);
downwards (with reverse gear
engaged) this activates/deactivates the
continuous operation of the rear window
wiper, regardless of the movement of the
windscreen wiper;
downwards (with reverse gear not
engaged) this activates/deactivates
intermittent operation (with actuating
frequency of about 3 seconds) of the
rear window wiper, regardless of the
or . The failure
movement of the windscreen wiper.
22) Make sure the device is turned off
whenever the windscreen glass must be
cleaned.
6) Never use the screen wiper to remove
layers of snow or ice from the windscreen
glass. In such conditions, the windscreen
wiper may be subjected to excessive
stress and the motor cut-out switch, which
prevents operation for a few seconds, may
intervene. If operation is not subsequently
restored, even after restarting the engine,
contact an Alfa Romeo Dealership.
