Headlamps on Reminder
A reminder tone sounds when the headlamps or parking lamps are manually turned on, if the driver’s door is open and the ignition is in LOCK or ACC. To turn the tone off, turn the knob all the way counterclockwise.
In the automatic mode, the headlamps turn off once the ignition key is in LOCK.
