2000 GMC Envoy Owner's Manual - Page 19

Safety Belts: They're for Everyone This part of the manual tells you how to use safety belts properly. It also tells you some things you should not do with safety belts. And it explains the air bag system. CAUTION: Don't let anyone ride where he or she can't wear a safety belt properly. If you are in a crash and you're not wearing a safety belt, your injuries can be much worse. You can hit things inside the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, you might not be if you are buckled up. Always fasten your safety belt, and check that your passengers' belts are fastened properly too. To return the head restraints to the upright position, reach behind the seats and pull the head restraint up until it locks into position. Push and pull on the head restraints to check that they have locked in the upright position. If they haven't, have them fixed immediately. The rear seat head restraints are adjustable. For information on adjusting the rear seat head restraints see "Head Restraints" in the Index. 1-7
