'03 4Runner_U (L/O 0305) In response to a severe side impact, the SRS side airbags and curtain shield airbags work with the seat belts to help reduce injury by inflating. The SRS side airbags help to reduce injuries mainly to the driver's or front passenger's chest and the SRS curtain shield airbags help to reduce injuries mainly to the driver's, front passenger's or rear outside passenger's head. The SRS side airbag and curtain shield airbag on the passenger side are activated even with no passenger in the front seat or rear seat. The curtain shield airbags may activate even when the side airbags are not activated. Be sure to wear your seat belt properly. Your vehicle is equipped with a crash sensing and diagnostic module, which will record the use of the seat belt restraint system by the driver and front passenger when the SRS side airbags and curtain shield airbags are inflated. CAUTION SRS side airbags and curtain shield airbags inflate with considerable force. To avoid potential death or serious injury when they inflate, the driver, front passenger and rear outside passengers must: D Wear their seat belts properly. D Remain properly seated with their back upright and against the seat at all times. This indicator comes on when the ignition key is turned to the "ON" position. It goes off after about 6 seconds. This means the SRS side airbags and curtain shield airbags are operating properly. This warning light system monitors the airbag sensor assembly, front airbag sensors, side and curtain shield airbag sensors, curtain shield airbag sensors, driver's seat position sensor, driver's seat belt buckle switch, front seat belt pretensioner assemblies, inflators, warning light, interconnecting wiring and power sources.
