DIPPED BEAMS DESCRIPTION

Description

The vehicle is equipped with two dipped beams in the headlamps.

The dipped beams are activated by turning a wheel on the stalk switch to the next position after the side light setting.

A special relay in the engine compartment junction unit controls activation of the low beams via two lines protected by specific fuses.

The low beam activation relay is managed by the body computer: relay excitation is activated by enablement signals with key in position M and a specific stalk switch command.

Activation/deactivation information is sent via the CAN network: in this way, the main beam warning light is activated in the instrument panel.

The body computer also manages the dipped beam maintenance function: when the main beams are turned on, the body computer keeps the dipped beams on.

If the dipped beams and the main beams are already on and the fog lights are turned on, then the dipped beams are switched off.

Similarly, if the dipped beams and the fog lights are on and the main beams are switched on, the dipped beams are switched off.

In other words, when the main beams and the fog lights are on, the dipped beams are always off.

The dipped beams can also be activated automatically, using the AUTO button on the steering column switch unit: this function is achieved by means of an infrared dusk sensor located in the windscreen.

Activation and deactivation is accompanied by an auditory warning signal.

When the device is switched on, the lights come on automatically even if the windscreen wiper is operated.

The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (key in position S) for a period of 45 seconds.

The side lights warning light in the instrument panel signals that the lights have remained on. The lights are activated by operating the light flasher stalk within 2 minutes of switching the engine off.
