Instrument Panel and Interior Switches Illumination - Overview
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Overview
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 illumination dim up switch to increase intensity or the dim down switch to decrease the intensity. The illumination components can be controlled directly (non-networked) or indirectly (networked) by a module.
Non-dimmable illumination is non-networked and provides backlighting to the window and door lock/unlock switches with the ignition ON or OFF while the accessory relay is energized.
