Dimmable Illumination
The dimmable illumination is used to provide backlighting to the IPC, switches, and control components (such as the FCIM and the FDIM) when the parking lamps are on.
If the exterior lamps are activated during daytime sunload conditions, the message center illumination remains at full intensity and does not dim from the instrument panel dimmer switch during this condition. If the vehicle travels under a bridge or a tunnel, the low level of ambient light causes the illumination level of the message center to change to the level set by the instrument panel dimmer switch. The message center illumination changes back to full intensity when the intense ambient light is restored.
The level of intensity is adjustable by rotating the instrument panel dimmer switch to increase or decrease intensity.
The dimmable backlighting system provides dimmable backlighting to the following components:
- Floor shifter (automatic transmission)
- Headlamp switch
- Hazard flasher lamp switch
- Steering wheel control switches
- Convertible top switch
- IPC
- FCIM
- FDIM
