Auto Headlamps
The headlamps and park/tail lamps will be activated by the
Body Control Module (BCM) when the headlamp switch is in the auto mode. To activate the auto headlamps the BCM requires that: (1) the headlamp switch is in the "A" position, (2) the engine is running, and (3) the light level sensed through the sun load sensor falls below the calibrated level.
