General description

GENERAL DESCRIPTION

The numerous light sources permit easy identification of the controls and switches and, when necessary, suitable lighting of the passenger compartment and/or specific points.

The wiring diagram relating to interior lighting has been divided into three parts; the first part includes the illumination of the ideograms on the controls and switches activated when the sidelights are switched on. The second includes courtesy lights and light points switched on and off by the timer when the doors are opened or closed.

A third specific diagram is dedicated to the dashboard lighting as this can be regulated using the rheostat.

Illumination of controls and ideograms:

When the sidelights are on, the ideograms located on the stalk unit are lit up; controls of the heater or of the manual conditioner (for the automatic heater and automatic air conditioner) control panel are also illuminated. (see "Heating-ventilation control unit: supply and diagnosis")

The specific diagrams also illustrate the illumination of the ideograms on the check panel display, and illumination of the ashtray, seat adjustment, fog-light switch and controls for the controlled suspension.

A specific light comes on when the glovebox is opened (see "Boot release control").

N.B. Refer to the various sections for greater detail and to the fault diagnosis if the ideograms do not light up

Courtesy lights:

A timing device N10 turns the front central courtesy light , the rear courtesy light F3 and, where applicable, the lights on the ignition block on or off when the doors are opened or closed. This device operates as follows:

• When any door is opened the lights come on and remain on for between 100 and 200 seconds or until the door is closed;
• when the doors have been closed the lights remain on for approximately 15 seconds and then switch themselves off.

The two courtesy lights can obviously be turned on manually by acting on the switch.

On the front courtesy light there is also a spot-light, powered directly by the battery, which enables a passenger, for example, to read without disturbing the driver.

A special courtesy light illuminates the luggage compartment and comes on when the boot lid is opened.

Instrument panel lighting:

The instrument panel C10 is illuminated by way of a rheostat B16, which permits the lighting intensity to be regulated.

ILLUMINATION OF CONTROLS AND IDEOGRAMS

Functional Description

The lever group ideograms B68 are illuminated when the sidelights are switched on; those on the left are activated directly by the light switch itself, while those on the right by a supply returning from the fusebox G1.

The controls of the heater F8 or the two lights F8a and F8b of manual air conditioner are supplied by the sidelights relay 164 and fuse F5 (10A) of G1 (see for the automatic conditioner "Heating ventilation - control unit: supply and diagnosis").
