Automatic Activation/Deactivation; Twilight Sensor - Ferrari 612 scaglietti Owner's Manual

Automatic activation/deactivation

When the light switch A is turned to AUT and the ignition key is in
position II (see page 49), the position lights, low beam lights and
number plate lights turn on and off according to the ambient light.
The high beams can only be turned on manually by pushing the left hand
lever B forwards.

If the high beam control is activated, they will come on
every time the lights are activated automatically. We
recommend therefore that you turn 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 activated automatically. The
driver must always be prepared to turn on the external lights
manually, even the rear fog lights if necessary.
After automatic activation of the external lights, it will always be possible to
turn on the rear fog lights manually. When the external lights are deactivated
automatically, also the rear fog lights are turned off (if active) automatically.
Therefore, if necessary, the user will have to turn on the rear fog lights
manually upon the next automatic activation.
The driver is always responsible for turning on the
external lights, depending on the ambient light and in
compliance with the regulations in force 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 is comprised of two sensors: a global sensor, which
measures the ambient light upwards, and a directional one, which
measures the ambient light in the vehicle's direction of travel, so as to
recognise tunnels, etc.
When the sensor is faulty, the system will turn on the low beams and
position lights independently of the ambient light. The failure message
will appear on the instrument panel display.
The failure message will be displayed as long as the light switch A is
turned to AUT.
In this case, we recommend that you deactivate the automatic system
and turn on the external lights manually if necessary. Contact the
Ferrari Service Network as soon as possible.
