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

• cigar lighter;
• climate control system controls (excluding the automatic air conditioning);
• preparation for radio phone;

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

• instrument pane display;
• switches in the doors;
• panel to the left of the steering wheel;
• controls in the centre of the dashboard;
• climate control system controls;
• radio display.

The light intensity can be adjusted to different levels, using two buttons, located in the left panel. there are 8 different settings. (from 30% to 1005 maximum intensity)The intensity level is set by pressing the 'MODE', 'MODE +' and 'MODE -' buttons and is shown on the instrument panel; the setting is also memorized and used later on.The light intensity level is also supplied, via the CAN, to the radio connectors 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.
