Folding the Rear Seats
The left and right rear seat cushions
can be lifted up separately to make
room for cargo.
Remove any items from the seat
before you fold up the seat cushion.
To fold a rear seat cushion, pull up
the lever on the outside of the
cushion. The seat cushion pops up,
and the seat legs store underneath it.
Push the cushion firmly against the
seat-back to lock it in place.
