This system activates a warning lamp for about 75 seconds and a buzzer for about 8 seconds when the ignition switch is turner to the RUN position, and the driver's seat belt is not buckled.

The warning lamp will be constant for the first 20 seconds, and then flash for the remaining 55 seconds. The buzzer only turns on, and will stay on, when the driver's seat belt is not fastened during the 8 second period. The warning lamp and buzzer has the following sequence of operation:

Driver's Seat Belt Unfastened

When the ignition switch is turned to the RUN position, the warning lamp illuminates constantly for 20 seconds, and then flashes for the remaining 55 seconds. The buzzer turns on and stays on for 8 seconds and then turns off. If the driver's seat belt buckle is fastened before the 8 seconds is over, the buzzer turns on for the balance of the time delay.

Driver's Seat Belt Fastened

When the ignition switch is turned to the RUN position, the warning lamp turns on and the buzzer stays off. At the end of 75 seconds, the warning lamp turns off. If the driver's seat belt buckle is unfastened prior to 8 seconds, the buzzer turns on for the balance of the 8 second delay.
