Instrument Panel and Interior Switches Illumination - Overview: Overview
WARNING: This page is about a different car, the 2017 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Dimmable illumination provides backlighting to switches and control components when the parking lamps are on or a set level of intensity when the ignition is on for non-dimmable components. The level of intensity for the dimmable backlit components is adjusted by pressing the instrument panel dimmer switch up to increase intensity or down to decrease intensity.
The illumination sources can be controlled directly (non-networked) or indirectly (networked) by a module.
