2011 Chevrolet Avalanche Owner's Manual - Page 74

3-12 Seats and Restraints { WARNING A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the safety belts are properly routed and attached, and are not twisted. { WARNING If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always be sure to press the rear of the seat cushion down. This action locks the seatback in place. Push and pull on the seatback to make sure it is locked. Raise the headrest. Safety Belts This section of the manual describes how to use safety belts properly. It also describes some things not to do with safety belts. { WARNING Do not let anyone ride where a safety belt cannot be worn properly. In a crash, if you or your passenger(s) are not wearing safety belts, the injuries can be much worse. You can hit things inside the vehicle harder or be ejected from the vehicle. You and your passenger(s) 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 passenger(s) are restrained properly too.
