COMFORT ADJUSTMENT 16G022 16G023 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 airbag sensors, 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 41.) The front airbags are designed to activate in response to a severe frontal impact within the shaded area between the arrows in the illustration. 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 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 front airbags may not work. However, this threshold velocity will be considerably higher if the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact, or if it is involved in an underride collision (e.g. a collision in which the nose of the vehicle "underrides", or goes under, the bed of a truck, etc.). 97
