2003 Chevrolet Corvette Owner's Manual - Page 11

Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their job when you're reclined like this. The shoulder belt can't do its job becauseit won't be against your body. Instead,it will be in front ofyou. In a crash you couldgo into it, receiving neck or other injuries. The lap belt can't do its jobeither. 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 in is motion, have the seatback upright.Then sit well back in theseat and wear your safety belt properly. But don't have a seatback reclined if your vehicle is moving. 1-4
