DESCRIPTION

The occupant detection sensor (separate type front seat cushion pad) detects if the passenger seat is occupied and sends signals to the combination meter assembly. The front seat inner belt assembly (front passenger seat) detects the front passenger seat belt condition and sends signals to the combination meter assembly. After receiving the signals from the occupant detection sensor (separate type front seat cushion pad) and front seat inner belt assembly (front passenger seat), the seat belt warning light on the combination meter assembly will blink or go off.

Tip:

The seat belt warning light on the combination meter assembly is used for both the driver seat and front passenger seat.
