2004 GMC Envoy Owner's Manual - Page 56

Here are the most important things to know about the air bag systems: CAUTION: (Continued) {CAUTION: You can be severely injured or killed in a crash if you are not wearing your safety belt - even if you have air bags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Air bags are designed to work with safety belts but do not replace them. Frontal air bags for the driver and right front passenger are designed to deploy only in moderate to severe frontal and near frontal crashes. They are not designed to inflate in rollover, rear or low-speed frontal crashes, or in many side crashes. And, for some unrestrained occupants, frontal air bags may provide less protection in frontal crashes than more forceful air bags have provided in the past. CAUTION: (Continued) The side impact air bags for the driver and right front passenger are designed to inflate only in moderate to severe crashes where something hits the side of your vehicle. They are not designed to inflate in frontal, in rollover or in rear crashes. Everyone in your vehicle should wear a safety belt properly - whether or not there is an air bag for that person. 1-50
