To recline the seatback, lift up on the recliner lever
located on the outboard side of the seatback. Use the
recliner lever to move the seatback to the desired
position.
It is easier to raise or lower the seatback if you lean
forward and take the weight off the seatback.
After raising a seatback to an upright position, push and
pull on the seatback to check that it is locked upright.
