If a door is open, a reminder chime will sound when your headlamps or parking lamps are manually turned on and your 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 or may remain on until the headlamp delay ends (if enabled in the DIC). See "Exit Lighting" under DIC Vehicle Customization .
