Rear Seats
Split Folding Rear Seat
Your vehicle may have a split folding rear seat. A split
folding rear seat allows you to carry long cargo by
folding down part or all of the rear seat. Before you can
fold the rear seatback, you need to unlatch the center
seatbelt buckle.
Use the following steps to lower one or both of the rear
seatbacks:
1. Insert a tool with a
small tip into the slot
as shown to unlatch
the seatbelt buckle.
Then move the belt to
the side so it is not
in your way.
2. There is a tab located
on the outboard sides
of the seatback. Pull
forward on the tab to
unlock the seatback.
3. Fold the seatback down. This will allow you direct
access to the trunk.
4. Repeat Steps 2 and 3 to fold down the other
seatback.
