Overview
Dimmable Backlighting
Dimmable illumination provides backlighting to switches and control components when the headlamps and parking lamps are on or off. The level of intensity is adjusted by pressing the instrument panel dimmer switch up to increase intensity or down to decrease intensity.
Non-dimmable Backlighting
Non-dimmable illumination provides backlighting to the window switches and to the outside rear view mirrors switch (for vehicles without door modules) with the ignition ON or OFF while the ignition relay is energized.
