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 characteristic of the item(s) or person on the front passenger’s seat monitored by the front passenger’s occupant detection system 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. The two inflators of each airbag are triggered either sequentially or simultaneously, depending on the severity of impact, in the case of the driver’s SRS frontal airbag and depending on the severity of impact and the characteristic of the item(s) or person on the seat in the case of the front passenger’s SRS frontal airbag. After deployment, the SRS airbag immediately starts to deflate so F
