COMFORT ADJUSTMENT 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 when the curtain shield airbags are inflated. CAUTION The curtain shield airbags inflate with considerable force. To avoid potential death or serious injury when they inflate, the driver and front passenger must: D Wear their seat belts properly. D Remain properly seated with their back upright and against the seat at all times. 16G022 The indicator comes on when the ignition key is turned to the "ON" position. It goes off after about 6 seconds. This means the SRS airbags are operating properly. This warning light system monitors the airbag sensor assembly, front airbag sensors, side and curtain shield airbag sensors, occupant detection sensor, seat belt buckle switch, front seat belt pretensioner assemblies, inflators, warning light, interconnecting wiring and power sources. (For details, see "Service reminder indicators and warning buzzers" on page 40.) The front airbags are designed to deploy in severe (usually frontal) collisions where the magnitude and duration of the forward deceleration of the vehicle exceeds the designed threshold level. The front airbags will work if the severity of the impact is above the designed threshold level, comparable to an approximate 25 km/h (15 mph) collision in the U.S.A. and 30 km (18 mph) collision in Canada when the vehicle has the impact straight into a fixed barrier that does not move or deform. 99
