When the taillights or headlights are ON, if the ignition key is
removed and the driver’s door is opened, a tone alarm will
sound continuously to warn that the lights are on. However, if
the taillights or headlights have been turned off by the headlight
automatic-shutdown function, the tone alarm will not sound.
