3-4 Seats and Restraints Lumbar Adjustment Reclining Seatbacks { Warning 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. The shoulder belt 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. To increase or decrease lumbar support, slide the control forward or rearward. To adjust the seatback: . Tilt the top of the control rearward to recline. Tilt the top of the control forward to raise. . The lap 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.
