Power Seat Reclining Seatbacks { CAUTION: You can lose control of the vehicle if you try to adjust a manual driver's seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver's seat only when the vehicle is not moving. { CAUTION: If the vehicle has front power seat(s), the controls are located at the front center of the seat cushion. To raise or lower the seat, move the center knob up or down. To move the seat forward or rearward, move the center knob toward the right or left. To raise or lower the front of the seat cushion, move the right lever up or down. To raise or lower the rear of the seat cushion, move the left lever up or down. If either seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatbacks to be sure they are locked. The seats have manual reclining seatbacks. The lever used to operate them is located on the inboard side of the seats. 1-3
