To adjust a seatback, pull up on the lever located on the outboard side of the driver's or front passenger's seats. Release the lever to lock the seatback where you want it. Push and pull on the seat to make sure it's locked into position. Pull up on the lever, and the seat will go to its original upright position. {CAUTION: 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 because it won't be against your body. Instead, it will 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 reclined if your vehicle is moving. 1-5
