SRS System Description - Front Passenger's Weight Sensor
The front passenger's seat is equipped with front passenger's weight sensors to detect the presence and size of the occupant in order to tailor front passenger's airbag deployment and performance. The front passenger's weight sensors are part of the front passenger's seat rail. If the sensors detect an empty front passenger's seat, the front passenger's airbag is disabled. If the weight sensors detect a front passenger's weight above approximately 30 kg (66 lbs), front passenger's airbag operation is allowed. If the sensors detect the weight of an infant or small child weighing up to about 30 kg (66 lbs), the system will automatically turn the front passenger's airbag off and indicate the front passenger's airbag cutoff indicator.
NOTE: The front passenger's weight sensors measure only the weight that's actually on the seat cushion. They do not measure the weight of the front passenger's legs extending to the floor or arms resting on the armrests. A front seat passenger who weighs near the airbag's cutoff threshold may cause the airbag and indicator to turn on and off just by moving around in the seat and shifting the occupant weight. This may cause some occupants to believe there's something wrong with the airbag system when it is operating normally.
