Kia Sedona: Stowing the rear seat belt
2nd row seat (for 2nd row center seat, if equipped)

3rd row

The rear seat belt buckles can be stowed in the pocket between the rear seatback and cushion when not in use.
Routing the seat belt webbing through the rear seat belt guides will help keep the belts from being trapped behind or under the seats.
After inserting the seat belt, tighten the belt webbing by pulling it up.
CAUTION
Remove the seat belt from the guides before using. If you pull on the seat belt when it is stored in the guides, it may damage the guides and/or belt webbing.
