Instrument Panel and Interior Switches Illumination - Overview

Overview 

Dimmable Illumination 

Dimmable illumination provides backlighting to switches and control components when the parking lamps are on. The instrument panel dimmer switch is used to increase or decrease the level of intensity for the dimmable backlit components. The BCM is the master module that controls the dimmable illumination.

Dimmable backlit switches and components are:

• Headlamp switch
• EPB switch
• Overhead console switches
• Media hub
• Hazard flasher switch
• Start-stop switch
• Steering wheel switches
• Power window switches
• Door lock switches

When the autolamp feature activates during the daytime, the message center illumination remains at full intensity and can not be dimmed using the instrument panel dimmer switch. If the vehicle travels under a bridge or through a tunnel and a low level of ambient light is detected, the illumination brightness of the message center changes to the last level set by BCM. The message center illumination changes back to full intensity when the intense ambient light is restored.

Non-Dimmable Illumination 

The non-dimmable illumination is on when delayed accessory is active. The delayed accessory is active:

• When the ignition is on.
• For up to 10 minutes after the ignition is cycled from on to off and a front door is not opened.

The power liftgate switch is non-dimmable.
