'03 4Runner_U (L/O 0305) Fold-down rear seats CAUTION D Do not allow passengers to ride on the flattened seat while driving; use the seat in the normal position. D After putting back the seat, try pushing the seat and seatback forward and rearward to make sure it is secured in place. Be certain to replace head restraint. BEFORE FOLDING DOWN REAR SEAT Stow the rear center seat belt buckle as shown in the illustration. This prevents the seat belt buckle from falling out when you fold the seatback. If you are using a trash holder, lower it. NOTICE The seat belt buckle must be stowed before you fold the seatback. 46 2003 4RUNNER from Apr. '03 Prod. (OM35820U)
