The vehicle is equipped with two dipped headlamps in the light
clusters.The dipped beam headlamps are switched on
through the steering column switch by turning the specific ring
to the position after the side lights.A special relay - in the underdashboard
control unit - controls the switching on of the dipped headamps
via two lines protected by special fuses.The relay for switching on the dipped headlamps
is managed by the Body Computer: the energizing of the relay is
activated by the go ahead signals with the ignition key in the ON position
(INT) and by the specific signal from the steering column switch
unit.With the dipped headlamps on, the simultaneous
presence of the main beam headlamps and fog lights commands disables
the dipped headlamps. The subsequent deactivation of one of these
two controls, with the dipped headlamps on, means that the dipped
headlamps have to be switched on again.The dipped headlamps are activated automatically,
via the dusk sensor, if the AUTO function is set on the steering
column switch unit.The dusk sensor is an infrared device that
operates at different levels of sensitivity. When the dusk sensor
is activated, a message appears on the control panel display that
indicates a preset sensitivity level (from 1 to 3). This intensity
may be adjusted using the 'Mode +' and 'Mode -' keys.
