Abstract
A secondary seat belt warning system for a motor vehicle includes at least one control module for activating at least one secondary warning signal. The secondary seat belt warning system also includes a driver seat belt sensor for producing an input signal indicative of a state of a driver seat belt between a buckled and unbuckled condition. The secondary seat belt warning system includes at least one passenger seat belt sensor for producing an input signal indicative of a state of at least one passenger seat belt between a buckled and unbuckled condition. The at least one control module communicates with the driver seat belt sensor and the at least one passenger seat belt sensor for activating the at least one secondary warning signal to alert a corresponding occupant of the motor vehicle if the state of at least one of the driver seat belt and the at least one passenger seat belt is the unbuckled condition.
