Instrument Cluster and Panel Illumination

INSTRUMENT CLUSTER AND PANEL ILLUMINATION
The instrument cluster and panel lighting system is powered through the headlamp switch and the panel dimmer switch. The instrument cluster illumination is controlled by the output of the panel dimmer switch. The instrument panel lighting circuit provides illumination for the:
- climate control assembly
- instrument cluster
- audio unit
- cruise control switches
- headlamp switch
- fog lamp switch (if equipped)
- 4WD switch (if equipped)

Principles of Operation
When the headlamp switch is in the PARKING LAMPS or HEADLAMPS ON position, the instrument panel dimmer switch provides a variable voltage to the instrument panel and all applicable switches depending on the driver-controlled level of intensity.
