When Should an Air Bag Inflate? {CAUTION: If something is between an occupant and an air bag, the bag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating air bag must be kept clear. Don't put anything between an occupant and an air bag, and don't attach or put anything on the steering wheel hub or on or near any other air bag covering. An air bag is designed to inflate in a moderate to severe frontal, or near-frontal crash. The air bag will inflate only if the impact speed is above the system's designed "threshold level." If the GVWR (Gross Vehicle Weight Rating) of your vehicle is 8600 or above, your vehicle has single stage air bags. If the GVWR is below 8600 then your vehicle has dual stage air bags. You can find the GVWR on the certification label on the rear edge of the driver's door. See Loading Your Vehicle on page 4-31 for more information. 1-71
