Ford Fusion: Instrument Panel and Interior Switches Illumination / Instrument Panel and Interior Switches Illumination - Overview. Description and Operation
Overview
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.
