DESCRIPTION

The vehicle is equipped with two main beam headlights located in the additional light units, which also include the daylight lights (D.R.L.) and side lights.    See E2010 SIDE LIGHTS / NO. PLATE LIGHTS The main beams are activated by operating the left steering wheel stalk:

• 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).

The main beam headlights command function is activated by enablement signals from the ignition switch with the key inserted and turned to MAR, and from the steering wheel interface control.The activation of the main beam headlights is managed by the Body Computer.A special relay in the engine compartment junction unit controls the activation of the main beams via two lines protected by a dedicated fuse.Activation/deactivation information is sent via the CAN: in this way, the main beam headlights warning light is activated in the instrument panel.If the main beam headlights were already activated during start-up (INT/A), they are temporarily excluded. When the key is next brought to the MAR position, the lights are activated once again.
