Airbags may inflate at different crash speeds. For example: • If the vehicle hits a stationary object, the airbag could inflate at a different crash speed than if the object were moving. • If the object deforms, the airbag could inflate at a different crash speed than if the object does not deform. • If the vehicle hits a narrow object (like a pole) the airbag could inflate at a different crash speed than if the vehicle hits a wide object (like a wall). Your vehicle may or may not have a side impact airbag. See Airbag System on page 1-56. Side impact airbags are designed 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 designed to inflate in frontal or near-frontal impacts, rollovers or rear impacts, because inflation would not likely help the occupant. A side impact airbag will only deploy on the side of the vehicle that is struck. 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 the angle of the impact and how quickly the vehicle slows down in frontal and near-frontal impacts. For side impact airbags, inflation is determined by the location and severity of the impact. • If the vehicle goes into an object at an angle the airbag could inflate at a different crash speed than if the vehicle goes straight into the object. The frontal airbags (driver and right front passenger) are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts because inflation would not likely help the occupants. 1-62
