position, lift up on the lever located
on the side of the seat cushion. This
will allow the seat back to be lifted
to the upright locked position.
Before returning the seatback to its original position, make sure
that cargo or any objects are not trapped underneath the
seatback. After returning the seatback to its original position, pull on
the seatback to ensure that it has fully latched. An unlatched seat may
become dangerous in the event of a sudden stop or collision.
