Automatic activation/
deactivation
When the light switch A is turned
to AUTO and the ignition key is in
position MAR, the position lights,
low beam lights and number plate
lights turn on and off automatically,
depending on the light outside.
WARNING: The high beams can only
be turned on manually by pushing the
left-hand lever forward.
If the low beams are
activated, they will come
on automatically every time
the lights are turned on. You are
therefore advised to turn off the high
beams every time the twilight sensor
deactivates the external lights.
In foggy conditions during
daytime, the position lights
and low beams are not
activated automatically. The driver
must always be ready to turn the
lights on manually, including the
front and rear fog lights.
WARNING: After the external lights
are turned on automatically, it is
always possible to turn on the front
and rear fog lights manually. When
the external lights are turned off
automatically, the front and rear fog
lights are turned off as well (if active)
and the next time the external lights
are switched on automatically, only
the front fog lights will activate.
Therefore, the user will have to turn
on the rear fog lights manually if
required.
The driver is always
responsible for turning
on the external lights,
depending on the light outside and
in compliance with the applicable
legislation in the country of use. The
automatic system for activating/
deactivating the external lights must
be considered an aid for the driver. If
necessary, turn the lights on and off
manually.
Twilight sensor
The twilight sensor consists of two
sensors: a global sensor, capable of
measuring the light intensity above
and a directional sensor, which
measures the light intensity in the
vehicle's travelling direction, enabling
it to recognise tunnels and driveways.
You can adjust the sensing range of
the twilight sensor by means of the
Multi Media System, by selecting
the "Confi guration" mode (see the
"Confi guration" section in the Multi
Media System manual).
In the event of a sensor failure, the
system will turn on the low beams and
the position lights, regardless of the
light outside, and a failure message
will appear on the instrument panel
display.
The failure indication will be
displayed as long as the switch A is
turned to AUTO.
In this case, we recommend that you
deactivate the automatic system and
turn on the external lights manually
if necessary; contact the Maserati
Service Network as soon as possible.
