{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

when the vehicle is not moving.If your vehicle has a manual bucket or a split
bench seat, you can adjust the seat forward or
rearward with the bar located under the front of the
seat cushion.
Lift the bar to unlock the seat. Slide the seat to
where you want it and release the bar. Try to move
the seat with your body to be sure the seat is
locked in place.
