  • The vehicle is fitted with the following new functions:
  • automatic activation of the hazard warning lights,
  • xenon lamps with automatic headlamp levelling (depending on version),
  • pulse-type control of the fog lamps,
  • automatic dipped-beam activation: management of exterior brightness by the light sensor (depending on version),
  • multiplexed steering column switch module,
  • multiplexed Engine Support Box (BSM), which manages the operation of the lamps at the front of the vehicle.

The exterior lighting and signalling functions manage the operation of the following components:

L’allumage ou l’extinction des feux s’effectue de l’une des manières

The lamps are switched on or off in one of the following ways:

  • manually: the user operates a control from the steering column switch module or from a switch.
  • automatically: when automatic mode is selected, the dipped-beam headlamps are switched on and off according to exterior brightness.

The switch-on or switch-off request is received by the BSI, which controls the components listed in the table below:

  • either directly,
  • or to the Engine Support Box (BSM) via the VAN CAR 1 network.
Nota : Les feux de recul et les feux de stop sont actionnés

Note: The reverse lamps and brake lamps are operated directly by their respective switches. The BSI receives the status information from the switches.
