USA models have a seat belt warning system — if the seat is occupied, the weight switch sounds a buzzer unless the belt is fastened. The buzzer is located under the dash to the left of the steering column.

Switch
The front seats have a weight-activated switch. It is important to get the switch in the correct position (see FSM for specific locating details).
Warning Lamp
To supplement the buzzer sound, 1972-1/2 (starting January 1972) and 1973 models also have "Warning" lamp prominently situated on top of the dash.
