Instrument Cluster and Panel Illumination: Notes
Illumination is used to provide backlighting to the dimmable and non-dimmable switches and control components.
If the exterior lamps are activated during daytime sunload conditions by the autolamp system, the Instrument Panel Cluster (IPC) message center (non-Hybrid) or the Liquid Crystal Display (LCD) (Hybrid), Audio Control Module (ACM), Front Controls Interface Module (FCIM), Front Display Interface Module (FDIM), the HVAC module and switch illumination remain at full intensity and do 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 IPC message center (non-Hybrid) or the LCD (Hybrid), the ACM, the FCIM, the FDIM, the HVAC module and switches to change to the level set by the instrument panel dimmer switch. The IPC message center (non-Hybrid) or the LCD (Hybrid), the ACM, the FCIM, the FDIM, the HVAC module and switch illumination change back to full intensity when the intense ambient light is restored.
