Automatic on and off

When the light switch A is turned to
MAR and the ignition key is in position
II, the position lights, low beam lights
and number plate lights turn on and
off according to the brightness
outside.
WARNING: The high beams can only be
switched on manually by pushing the
left-hand lever forwards.
If the low beams are
activated, they will come on
4
automatically every time the
lights are switched on. We recommend
therefore that you switch them off
every time the twilight sensor
deactivates the external lights.
In case of fog during the day,
the position lights and low
beams will not be turned on
automatically. The driver must always
be ready to turn the lights on
manually, including the front and rear
fog lights.

External lights and direction indicators
WARNING: After the external lights
have switched on automatically, the
front and rear fog lights can always be
turned on manually. When the
external lights are switched off
automatically, the front and rear fog
lights are also switched off (if active)
and the next time the external lights
are switched on automatically, only the
front fog lights will come on.
Therefore, the user will have to switch
the rear fog lights on manually if these
are required.
The responsibility for
switching on the lights,
depending on the daylight
and the regulations in force in the
country of use, always lies with the
driver. The automatic system for
switching on and off the external
lights is to be considered as an aid for
the driver. If necessary, switch the
lights on and off manually.

Twilight sensor

The twilight sensor is composed of two
sensors: a global sensor, which
measures the brightness upwards, and
a directional one, which measures the
brightness in the vehicle's travelling
direction, so as to recognise tunnels,
avenues and galleries.
If the sensor should fail, the system will
switch on the low beams and the side
lights, regardless of the brightness of
light outside, and the failure message
will appear on the instrument panel
display.
The failure indication will be displayed
so long as the switch A is turned to
AUTO.
In this case, we recommend that you
switch off the automatic operation for
the external lights and switch the
latter on manually if necessary; contact
the Maserati Service Network as soon
as possible.
