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. You can find the GVWR on the certification label on the rear edge of the driver's door. See Loading Your Vehicle on page 4-30 for more information. Single Stage Airbags If your vehicle has frontal airbags with single stage deployment and your vehicle goes straight into a wall that does not move or deform, the threshold level is about 9 to 16 mph (14 to 26 km/h). (The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.) • 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. The frontal airbags (driver and right front passenger) are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts. 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. Inflation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down in front or near-frontal impacts. If the GVWR (Gross Vehicle Weight Rating) of your vehicle is 8,500 lb (3 855 kg) or above, your vehicle has single stage airbags. If the GVWR is below 8,500 lb (3 855 kg) then your vehicle has dual stage airbags. Dual Stage Airbags If your vehicle has frontal airbags with dual stage deployment, the restraint will adjust according to the crash severity. Your vehicle is equipped with electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. For moderate frontal impacts, these airbags inflate at a level less than full deployment. For more severe frontal impacts, full deployment occurs. 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 16 mph (19 to 26 km/h), and the threshold level for a full deployment is about 16 to 25 mph (26 to 40 km/h). (The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.) 1-69
