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.
To move a manual seat forward or rearward:
Try to move the seat with your body to be sure the seat is locked in place.
On vehicles with this feature, adjust the manual leg extension by reaching under it, in the pocketed area. Press the release button and pull or push to lengthen or shorten it. Release the button to lock it in place.
