Parade Dimming
This feature does not let the instrument panel display screens dim during daylight hours while the ignition is in the ACC/ACCESSORY or ON/RUN position and the parking lamps or headlamps are on. Parade dimming automatically works with the light sensor, located on top of the dashboard. If it is dark enough outside and the parking lamps or headlamps are on, the instrument panel display screens can be adjusted by turning the instrument panel brightness knob clockwise or counterclockwise to brighten or dim the lighting. See Instrument Panel Illumination Control.
The instrument panel control backlighting can still be adjusted while in parade mode.
