Lighting System

Component Location Index

Automatic Lighting System: When the combination light switch is in the "AUTO" position, the automatic lighting control

unit turns on the headlights, all other exterior lights, and the instrument panel lights when the ambient light is low. The
control unit receives signals from the automatic lighting sensor, which senses the lux (illumination) level outside the vehi-
cle, and it controls the lights by means of the lighting relay and taillight relay.

NOTE: The exterior lights (other than the headlights) circuit is included with the fog lights circuit. While in the "AUTO"
mode, when the exterior lights are turned off, the fog lights are turned off automatically.

While in the "AUTO" mode, the light will remain on when the ignition switch is turned off.
They will turn off automatically when the driver's door is opened.
