Rain sensor
The function of the rain sensor
is to adapt the frequency of the
windscreen wiper 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 moving the right-
hand lever to position B. The sensor
has a setting range that varies
progressively: from the windscreen
wiper stationary position - when the
windscreen is dry - to the windscreen
wiper second speed - in conditions of
pouring rain.
To regulate the frequency of
intermittent operation, with the lever
in position B, turn the end section F of
the lever.
Rotating the lever end section
clockwise, intermittent operation
varies from fast intermittent wipe
(max.) to slow intermittent wipe
(min).
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 back to position B.
Before cleaning the
windscreen (for example at
the service station) make
sure the rain sensor is deactivated or
that the key is turned to STOP. The
rain sensor must be deactivated also
when washing the vehicle by hand or
in automatic car washes.
WARNING: If there is ice or snow on
the front windscreen, do not activate
the rain sensor to avoid damaging the
wiper motor.
F
Sensor failure
When the rain sensor is activated, in
the event that it is malfunctioning,
the windscreen wiper will be switched
on in intermittent operation mode
and the sensing range will be set by
the user, regardless of whether or not
there is rain on the windscreen.
The symbol appears on the
display.
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.
