COMFORT ADJUSTMENT CAUTION D Make sure the roll sensing of curtain shield airbags off indicator light is not on. D When the roll sensing of curtain shield airbags off switch is turned on (and the roll sensing of curtain shield airbags off indicator light is on), the curtain shield airbags will not inflate in a vehicle rollover. Turning off the curtain shield airbags can reduce the occupant protection which your vehicle safety systems can provide to you in certain accidents and increase the likelihood of death or serious injuries. 16x502a This indicator comes on when the ignition switch 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 sensor assemblies, curtain shield airbag sensor assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt pretensioner assemblies, inflators, warning light, interconnecting wiring and power sources. (For details, see "Service reminder indicators and warning buzzers" on page 48.) 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 when the vehicle has the impact straight into a fixed barrier that does not move or deform. 139
