When the park lamps are on and the ambient light sensor indicates low light conditions, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

Battery voltage is supplied to the solid state dimmer portion of the headlamp switch when the headlamp switch is in the PARK or HEAD position. The solid state dimmer supplies an adjustable amount of voltage to the instrument cluster, gauge cluster, and to other interior displays. The solid state dimmer is grounded to G103 through the headlamp switch. All of the interior displays are grounded through either G103, G200, or G201.
