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):

• hazard warning lights,
• controls on front and rear 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:

• cigar lighter/ashtray;
• ashtray light

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

• instrument panel and displays.
• switches in the door;
• left panel;
• switch unit on the tunnel.
• climate control system controls;

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, via the CAN, to the radio connectors (or the radio-phone-navigator) and 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.
