If the front of your vehicle goes straight into a wall that does not move or deform, the threshold level for the reduced deployment is about 12 to 18 mph (19 to 29 km/h), and the threshold level for a full deployment is about 18 to 22 mph (29 to 35.4 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range. Frontal airbags may inflate at different crash speeds. For example: • If the vehicle hits a stationary object, the airbags could inflate at a different crash speed than if the vehicle hits a moving object. • If the vehicle hits an object that deforms, the airbags could inflate at a different crash speed than if the vehicle hits an object that does not deform. • If the vehicle hits a narrow object (like a pole), the airbags could inflate at a different crash speed than if the vehicle hits a wide object (like a wall). • If the vehicle goes into an object at an angle, the airbags could inflate at a different crash speed than if the vehicle goes straight into the object. 74 Frontal airbags (driver and right front passenger) are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts. Your vehicle may or may not have side impact airbags. See Airbag System on page 68. Side impact airbags are intended to inflate in moderate to severe side crashes. A side impact airbag will inflate if the crash severity is above the system's designed threshold level. The threshold level can vary with specific vehicle design. Side impact airbags are not intended to inflate in frontal or near-frontal impacts, rollovers, or rear impacts. Both side impact airbags will deploy when either side of the vehicle is struck unless the passenger sensing system has turned off the passenger's side impact airbag. See Passenger Sensing System on page 77 for more information. In any particular crash, no one can say whether an airbag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. For frontal airbags, inflation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down in frontal or near-frontal impacts. For side impact airbags, inflation is determined by the location and severity of the impact.
