Reclining Front Seatbacks
To adjust the seatback, lift the lever located on the
outboard side of the seat and move the seatback to
where you want it. Release the lever and push rearward
on the seatback to make sure it is locked. Pull up on the
lever without pushing on the seatback and the seatback
will go to an upright position.
But don’t have a seatback reclined if your vehicle is moving.
