wiping operates automatically and is
disabled when the external temperature
is below 0°C.
Deactivation
Use ring fig. 48 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
failure is indicated on the display.
The sensor continues to operate and it
is possible to set the windscreen wiper
to continuous mode
or . The failure

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. 48 (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
movement of the windscreen wiper.
WARNING
29) Make sure the device is turned off
whenever the windscreen glass must be
cleaned.
IMPORTANT
8) 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.
9) Do not operate the screen wiper with the
blades lifted from the windscreen glass.
10) Do not activate the rain sensor when
washing the car in an automatic car wash.
11) Make sure the device is switched off if
there is ice on the windscreen glass.
