Folding Rear Seat
The rear seatbacks can be folded forward to provide an
additional storage area. To fold the rear seatback, pull on
the loops located on the upper seatback.
NOTE: These loops can be tucked away when not in use.
After releasing the seatback, it can be folded forward.
When the seatback is folded to the upright position, make
sure it is latched by strongly pulling on the top of the
seatback above the seat strap.
