2003 GMC Yukon Owner's Manual - Page 82

{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. Don't let seat covers block the inflation path of a side impact air bag. If your vehicle has one, the right front passenger's side impact air bag is in the side of the passenger's seatback closest to the door. When Should an Air Bag Inflate? Frontal Air Bags The driver's and right front passenger's frontal air bags are designed to inflate in moderate to severe frontal or near-frontal crashes. But they are designed to inflate only if the impact speed is above the system's designed "threshold level." 1-76
