Folding the 60/40 Split Bench Seatbacks
The rear seat may have a 60/40 split seat which may be
folded down to create a load floor and give you more
cargo space. The rear seatbacks are equipped with
rearward folding head restraints. When the seatback is
being folded down, the head restraint will automatically
fold rearward to allow a flat load floor for cargo or entry
to the third row seat.
To fold the rear seat, do the following:
1. Insert the two safety belt buckles into the pocket in
the seatback before folding the rear seat on the
driver's side.
That way, the buckles will be out of the way when
the seat is folded and will be available for passengers
to use when the seat is returned to the passenger
position. Also, make sure that nothing is under or in
front of the seat.
2. Make sure the seatback is in an upright position
(unreclined) before folding it.
4. Pull the seatback forward and fold it down until it
is flat.
3. Pull up on the strap loop
located at the rear of the
seat cushion and pull the
seat cushion up. Then
fold it forward.
