Dimmable Illumination

The Instrument Panel Cluster (IPC) and panel illumination is used to provide backlighting to the instrument panel, switches, and control components when the parking lamps are on. The level of intensity is adjustable by pressing the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.

The dimmable switches and components are illuminated when the parking lamps are ON. The digital dimmer switch is a double detent rocker switch used to control all dimmable interior illuminated components, and to control the courtesy lamps. The first up detent increases dimmable backlighting intensity. The first down detent decreases dimmable backlighting intensity. The second up detent turns on the courtesy lamps. The second down detent turns the courtesy lamps off (the courtesy lamps are controlled by other features).

The dimmable backlighting components are:

• Audio Control Module (ACM) (vehicles with navigation)
• Front Controls Interface Module (FCIM)
• Front Display Interface Module (FDIM) (vehicles without navigation)
• SJB
• Floor shifter
• HVAC module (vehicles without navigation)

• Luggage compartment lid release switch
