If a door is open, a reminder chime sounds when the headlamps or parking lamps are manually turned on and the key is out of the ignition. To turn off the chime, turn the headlamp switch to off or auto and then back on, or close and re-open the door. In the auto mode, the headlamps turn off once the ignition is in LOCK/OFF or may remain on until the headlamp delay ends, if enabled in the Driver Information Center (DIC). See "Exit Lighting" under DIC Vehicle Customization .
