• If the ignition switch is in the ON position (or the key has been removed) and the glove box is opened, its light will remain on for 20 minutes and then switches off automatically. The lamp comes on again if any door is opened, or if the ignition switch is turned to on.
• If the ignition switch is in the ON position (+15 and +54) and the glove box is opened, its lighting will remain on until the glove-box door is closed.

The power supply to the glove box light is shared with the reading lights.

The lighting goes out while the engine is started (starter motor cranks). However, it does not stay off for more than 20 seconds.

So as not to burden the battery more than is necessary, DICE switches the lighting off when the starter motor is activated. When the ignition switch reverts from the ST position to ON, DICE switches the lighting on again. For safety reasons the shut-off time is maximized to 20 seconds, so that the lighting will function even if +54 is lacking in the event of a fault.

Voltage +30 for the glove-box lighting is always fed to DICE via fuse 20. Power is fed from pin 70 on the control module to the lamp (19).
