When the ignition SW turned on, a signal is input to the combination meter and the center cluster integration panel (w/
navigation system) or the A/C control assembly (w/o navigation system). To determine whether the driver has fastened the
seat belt, a signal is input from the buckle SW LH to the combination meter. When the seat belt is not fastened, the seat belt
warning light in the combination meter blinks, and emits a warning sound.
In addition, the front passenger is recognized by a sensor (Seat belt warning occupant detection sensor) is installed in the
front passenger seat, and determines whether the seat belt is fastened. When not fastened, the signals from the seat belt
warning occupant detection sensor and the buckle SW RH is input to the center cluster integration panel (w/ navigation
system) or the A/C control assembly (w/o navigation system), and the passenger seat belt warning light blinks to warn the
passenger.
