When the headlight switch is in the ON or AUTO position and all doors (and tailgate) are closed and locked, if you press the door unlock button on the transmitter (or smart key), the headlights will come on for about 15 seconds.
If the headlight switch is in the AUTO position, the function can only operate at night.
At this time, if you press the door unlock button again or door lock button on the transmitter (or smart key), the headlights will turn off immediately.
