Rain sensor
The function of the rain sensor is to
adapt the frequency of the windshield
wiper's strokes (in the intermittent
operation mode) to the intensity of the
rain.
All the other functions controlled by
the right-hand lever (windshield
wipers off, headlight and windshield
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 windshield wiper's stationary
position - when the windshield is dry -
to the windshield 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 windshield 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
windshield (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 off also when washing
the car by hand or in automatic car
washes.
WARNING: In case of ice or snow on
the front windshield, 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
windshield 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 windshield.
In this case, we recommend that you
turn off the rain sensor and turn on the
wiper, if necessary, in continuous
mode. Contact your local Authorized
Maserati Dealer as soon as possible.
