Dimmable Backlighting

The dimmable backlighting system consists of the following components:

• Floor shifter
• LH rear heated seat switch (if equipped)
• RH rear heated seat switch (if equipped)
• Memory set switch (if equipped)
• Media hub illumination
• Power liftgate switch (if equipped)
• Window control switches (MKX)
• Door lock control switches (MKX)
• Roof opening panel switch (MKX)
• Start/stop switch (if equipped)
• Steering wheel switches
• Instrument panel dimmer switch (Integral to the Front Lighting Control Module (FLM))
• FLM
• Instrument Panel Cluster (IPC)
• Body Control Module (BCM)
• Front Controls Interface Module (FCIM)
• Front Control/Display Interface Module (FCDIM) (if equipped)
• Front Display Interface Module (FDIM) (if equipped)

Dimmable illumination provides backlighting to the IPC, switches, and control components when the parking lamps are on. The level of intensity is adjusted by pressing the instrument panel dimmer switch up to increase intensity or down to decrease intensity.

The dimmable switches and components are illuminated when the parking lamps are on. The instrument panel dimmer switch, which is integral to the Front Lighting Control Module (FLM), controls all dimmable interior illuminated components.

On vehicles equipped with autolamps, if the exterior lamps are activated during the daytime, 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.
