2005 GMC Envoy Owner's Manual - Page 59

Here are the most important things to know about the airbag system: 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 airbags. Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are "supplemental restraints" to the safety belts. All airbags are designed to work with safety belts but do not replace them. Frontal airbags 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 airbags may provide less protection in frontal crashes than more forceful airbags have provided in the past. CAUTION: (Continued) The roof-mounted airbags 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 or in rear crashes. If the vehicle is equipped with rollover capable airbags, it has been designed to deploy the roof-mounted airbags in the event of a vehicle rollover. Everyone in your vehicle should wear a safety belt properly - whether or not there is an airbag for that person. 1-53
