1996 Cadillac DeVille Owner's Manual - Page 21

A CAUTION: Sitting in a reclined position whenyour vehicle is in motion can be dangerous. Even if you buckle when up, your safetybelts can't do their job you're reclined like this. The shoulderbelt can't do itsjob because it won't be against yourbody. Instead, itwill be in front of you. In a crash you could go into it, receiving neck or other injuries. The lap belt can't do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly. But don't have a seatback reclinedif your vehicleis moving. 1-6 -
