Instrument Panel and Interior Switches Illumination - Overview: Overview

Dimmable Backlighting 

Dimmable illumination provides backlighting to switches and control components when the headlamps or parking lamps are on. The level of intensity is adjusted by pressing the instrument panel dimmer switch up to increase intensity or down to decrease intensity.

All vehicles are equipped with networked and non-networked dimmable illumination.

Non-dimmable Backlighting 

Non-dimmable illumination provides backlighting to the window switches and to the outside rear view mirror switch (for vehicles without door modules/one touch down driver window system) with the ignition ON or OFF while the ignition relay is energized.

Non-dimmable illumination is not networked.
