2002 Chevrolet Impala Owner's Manual - Page 14

When the seat is not in use, it should be kept in the upright locked position. If you plan to load items into the trunk through the split folding rear seat, you must first turn off the trunk release sensor. See "Trunk Release Sensor" in the Index for more information. 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: If the seatback isn't locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. 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. CAUTION: A safety belt that is improperly routed, not properly attached, or twisted won't 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. 1-8
