2001 GMC Sierra 1500 Pickup Owner's Manual - Page 25

To return the seat to the passenger position, lift the floor load panels and latch them into the seatback. Lift the seatback up and push rearward all the way. Then lower the seat cushion until it latches into position. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place. Check to see that the buckles on the driver's side seatback are accessible to the outboard and center occupant and are not under the seat cushions. 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. 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. 1-12
