For easy modification of your
interior vehicle space, all the rear seats
can be individually folded: onto the
second-row floor, and under the third-
row floor. You can then have a load
floor that is continuous up to the front
seat backrests.
The seats must only be folded and
unfolded with the vehicle stationary.
