WARNING: Do not place cargo or any objects behind the seat backrest before returning it to the original position. Pull on the seat backrest to make sure that it has fully latched after returning the seat backrest to its original position. An unlatched seat may become dangerous if you stop suddenly or have a crash.
Lift the seat backrest toward the rear of the vehicle.
Rotate the seat backrest until it engages, locking it in the upright position.
