DESCRIPTION
The vehicle is equipped with two high beams in the headlamps.
The main beams are switched on by the steering wheel interface:
- with the dipped beams on, by pushing the lever towards the dashboard (stable mode)
- in flashing mode, by pulling the lever toward the steering wheel (unstable mode)
|
There are two main beam bulbs on versions with gas discharge headlamps: The first traditional (halogen) one comes on in "flashing" mode; when there is a switch from dipped to main beam headlamps, the xenon bulb remains on and a metal screen is moved, by means of a motor, being lowered for dipped headlamp operation and raised for main beam headlamp operation. |
The switching on of the main beam headlamps is managed by the Body Computer.
A dedicated relay in the engine compartment junction unit controls the activation of the main beams via a line protected by a dedicated fuse. The dipped beam activation relay is controlled by the Body Computer: relay energizing is activated via a specific stalk unit control signal.
Activation and/or deactivation information is sent via the CAN: in this way, the main beam warning light is activated in the instrument panel.
