INSTRUMENT LIGHTING - Description

Description

The vehicle has numerous light sources for optimum lighting of the instruments and the controls.

Some of these are lit up when the ignition is ON (INT), others with the side lights on and on others the intensity varies according to a dimmer logic managed by the Body Computer.

The following controls light up when the ignition is turned ON (INT):

  • control panel on the tunnel.
  • controls in the centre of the dashboard.
  • controls on the front courtesy lights

The Body Computer manages the lighting of the following using the go ahead signals with the ignition ON (INT) and the side lights:

  • current socket;
  • climate control system controls;
  • radio

The Body Computer (directly or via the door control units) manages the dimmer for the:

  • instrument panel and displays.
  • switches in the door;

The light intensity can be adjusted to different levels, using an outside button, located in the left panel. there are 8 different settings.

The intensity level is set by pressing the 'MODE +' and 'MODE -' buttons and is shown on the instrument panel; the setting is also memorized and used later on.

- the light intensity cannot, however, be reduced to zero.

The light intensity level is also supplied to the climate control system control unit to dim the backlighting of the displays: it ranges from maximum lighting (daytime) to dimmed lighting (nighttime): the same logic also adjusts the control button lighting.
