For 1990-2009 cars

To adjust the seatback on a manual seat, lift the lever on the outer side of the seat and move the seatback to where you want it. Then release the lever to lock the seatback in place.

On a power driver's seat, adjust the seatback by pressing the RECLINE switch forward or rearward.

But don't have a seatback reclined if your vehicle is moving.

Caution: Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the safety belts cannot do their job when reclined like this.

The shoulder belt cannot do its job because it will not 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 cannot 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 the safety belt properly.
