WARNING: Before returning the seatback to its original position,
make sure that cargo or any objects are not trapped behind the
seatback. After returning the seat back to its original position, pull on
the seatback to make sure that it has fully latched. An unlatched seat
may become dangerous in the event of a sudden stop or crash.
The lumbar support control is located on the inboard side of the driver's
seat. Turn the control to adjust your support.
