Windscreen wiper/washer and headlight washers
Rain sensor
The function of the rain sensor is to
adapt the frequency of the windscreen
wiper’s strokes (in the intermittent
operation mode) to the intensity of the
rain.
All the other functions controlled by
the right-hand lever (windscreen
wipers off, headlight and windscreen
washer in continuous slow and fast
operation mode and in temporary fast
operation mode) remain the same.
The rain sensor is activated
automatically by bringing the right-
hand lever to position B. The sensor's
setting range varies progressively,
from the windscreen wiper's stationary
position - when the windscreen is dry -
to the windscreen wiper's second
speed - in conditions of pouring rain.
To regulate the frequency of
intermittent operation, with the lever
on the B position, rotate the end
section of the lever F.
Rotating the end section clockwise,
intermittent operation varies from a
maximum (fast intermittent wipe) to a
minimum (slow intermittent wipe).
If the engine is turned off during
automatic windscreen wiper
operation, with the lever in position B,
to reactivate the function the next
time the engine is started, the lever
must be moved to A (stop position)
then returned to position B.
Before cleaning the front
windscreen (for example in
service stations) make sure
the rain sensor is deactivated or that
the key is turned to STOP. The rain
sensor must be cut-out also when
washing the car by hand or in
automatic car washes.
WARNING: In case of ice or snow on
the front windscreen, do not activate
the rain sensor to avoid damaging the
wiper motor.
Sensor failure
When the rain sensor is activated, in
the event that it is malfunctioning, the
windscreen wiper is switched on in the
intermittent operation mode and the
sensing range is set by the user,
regardless of whether or not there is
rain on the windscreen.
In this case, we recommend that you
cut-out the rain sensor and turn on the
wiper, if necessary, in continuous
mode. Contact the Maserati Service
Network as soon as possible.
