Function
Interior lights circuit

The interior lights circuit supplies the ceiling lights, the loading area lights and the footwell lights.

The interior lights can be operated by hand when the alarm system is not armed and the ignition key is not in position 0. Automatic operation is only possible in ignition key position 0 or 1. With automatic operation, the interior lights go on and off slowly.

The interior lights can be manually activated by pressing the button mounted beside the ceiling light. Pressing the button a second time switches the lights OFF.

To switch off the interior lighting permanently, the main interior light switch must be pressed for 5 seconds. After 5 seconds, the lights go out after a short flash. In this mode, the interior lights can only be operated manually. The automatic mode can be reactivated by pressing the main interior light switch for 5 seconds. After 5 seconds, the lights flash and go on. If the crash sensor is activated while the ignition key is in position 1 or 2, the automatic mode is also activated.

The automatic mode remains activated when the interior light switch is pressed as normal (less than 5s).

When the interior light switch is used to activate the light, the lights remain on for 16 minutes, no matter what the position of the ignition key.

All lights go out gradually after 16 minutes if the key is not pressed again. (Power Down mode).

A table of the states and ignition key positions for the gradual activation and deactivation of the lights appears below:
