Seats and Seat Controls This section tells you about the seats -- how to adjust them and fold them up and down. It also tells you about reclining front seatbacks and head restraints. If your vehicle has a manual bucket, split bench or full bench seat, you can adjust it with this lever at the front of the seat. Manual Front Seat You can lose controlof the vehicle if you try to adjust a manual driver's seat while the vehicleis moving. The sudden movement could startle and confuse you, or make you push a pedal when you don't want to. Adjust the driver's seat only when the vehicle is not moving. Slide the lever at the front of the seat toward the passenger's side to unlock it. Using your body, slide the seat to where you want it. Then, release the lever and try to move the seat with your body to make sure the seat is locked into place. 1-2
