WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The headlamps on warning chime will sound when the driver door is opened, with the key in the OFF position and the key out, and the instrument cluster detects the instrument illumination lamps are on. The headlamp on reminder chime is only operative when autolamp is not selected.
