a. In the occupant classification system, the occupant classification ECU calculates the weight of the front passenger based on a signal from the
occupant detection sensor. This system judges the occupant to be a child when it detects a weight of less than 27.3 kg (60 lb), and disables the
front passenger side airbag and front passenger side - side airbag.
b. This system is mainly composed of the occupant detection sensor that detects the load on the front passenger seat. The occupant classification
ECU controls the system, and the passenger airbag ON/ OFF indicator indicates the ON/OFF condition of the front passenger airbag and front
passenger side - side airbag.
