Headlamp: Description and Operation

HEADLAMP TIME DELAY SYSTEM
The optional Headlamp Time Delay system is controlled by the Body Control Module (BCM) and a relay located in the junction block. The headlamp time delay system can be activated by turning ON the headlamps when the engine is running, turn OFF the ignition switch, then turn OFF the headlamp switch. The BCM will allow the headlamps to remain ON for 90 seconds before they automatically turn OFF. Refer to the Owner's Manual for more information.

The headlamp time delay operates when the ignition switch is turned OFF while the headlamps are still ON, and the headlamps are then turned OFF within 45 seconds after the ignition is OFF. This will provide a 90-second time delay before turning OFF the headlamps.
