Interior Lamps Dimming

When the ignition switch is in the ON position, the Vacuum Fluorescent (VF) displays turn on at maximum brightness. When the park lamps are on and the ambient light sensor indicates nighttime conditions, all incandescent switch backlighting turns on at the dimming level indicated by the IP dimmer switch and all VF displays dim to match the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all VF displays and incandescent switch backlighting dimming level goes from minimum intensity to maximum brightness in response to the IP dimmer switch.
