The indicator comes on when the ignition key is turned to the "ACC" or "ON" position. It goes off after about 6 seconds. This means the SRS is operating properly. The SRS warning light system monitors the airbag sensor assemblies, inflators, seat belt pretensioners, warning light, interconnecting wiring and power sources. There may be the case that the driver and passenger airbags and seat belt pretensioners will not activate with such an impact in which the occupant wearing the seat belt correctly would not get serious injury. The driver and front passenger airbags and seat belt pretensioners will work if the severity of the impact is above the designed threshold level, comparable to an approximate 25 km/h (15 mph) collision when impacting straight into a fixed barrier that does not move or deform. If the severity of the impact is below the above threshold level, the driver and front passenger airbags and seat belt pretensioners may not work. 94
