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).
