DESCRIPTION & OPERATION
If the driver's seat belt is not buckled, and the ignition switch is turned to the "ON" or "START" position, the seat belt warning system will light the "FASTEN SEAT BELTS" indicator and sound the buzzer for approximately 8 seconds.
If the driver's belt is buckled after the buzzer sounds, the buzzer will still remain on for 8 seconds. When the ignition switch is turned to the "ON" position, current is supplied through the timer to the buzzer circuit and indicator light circuit.
The light will always remain on until the timer turns off the current. The buzzer will only sound if the driver's seat belt is not buckled before turning on the ignition switch. The seat belt warning buzzer is grounded by a switch in the driver's seat inboard buckle. The warning chime module is located behind the instrument cluster.
