1-46 Seat, seatbelt and SRS airbags ! Operation The SRS airbag can function only when the ignition switch is in the "ON" position. The Subaru advanced frontal airbag system is designed to determine the activation or deactivation condition of the front passenger's SRS frontal airbag depending on the total load on the front passenger's seat monitored by the front passenger's occupant detection system weight sensor. For this reason, only the driver's SRS frontal airbag may deploy in the event of a collision, but this does not mean failure of the system. If the front sub sensors and the impact sensors in the airbag control module detect a predetermined amount of force during a frontal collision, the control module sends signals to the airbag module(s) (only driver's module or both driver's and front passenger's modules) instructing the module(s) to inflate the SRS frontal airbag(s). The driver's and front passenger's SRS frontal airbags use dual stage inflators. A) B) 1) 2) Driver's side Passenger's side SRS AIRBAGs deploy as soon as a collision occurs. After deployment, SRS AIRBAGs start to deflate immediately so that the driver's vision is not obstructed.
