The seat belt indicator is a LED display located in the instrument cluster. The BCM uses Class 2 communication in order to inform the instrument cluster when to turn ON the seat belt indicator. The seat belt system has an enhanced seat belt warning system. The system activates the following components when the ignition has been turned to the RUN position and the driver's seat belt has not been buckled:

The seat belt warning lamp will be ON constant for the first 20 seconds and will FLASH for the remaining 55 seconds. The audible warning will stay ON when the driver seat belt is not fastened during the 8 second time period. The sequence of operation of the warning lamp and audible warning follows:
