Instrument Cluster and Panel Illumination

Dimmable Backlighting

The dimmable backlighting system consists of the following components:

- Ambient lighting switch
- Floor shifter
- Hazard/Passenger Air Bag Deactivation (PAD)/traction control switch
- Headlamp switch
- Hill descent control switch (Raptor only)
- Instrument panel dimmer switch
- Mode select switch
- Off-road mode switch (Raptor only)
- Overhead console
- Steering wheel switches
- Upfitter switch
- Audio Control Module (ACM) (base audio)
- Front Controls Interface Module (FCIM)
- Front Display Interface Module (FDIM) (vehicles without navigation)
- HVAC module
- Instrument Panel Cluster (IPC)
- Trailer Brake Control (TBC) module

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

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.

Non-Dimmable Backlighting

The non-dimmable backlighting system consists of the following components:

- Door lock control switches
- Rear heated seat switches
- Window control switches

Non-dimmable illumination provides backlighting with the ignition on or ignition off while the accessory delay relay is energized.
