Chrysler 2008 Aspen - Manual (Page 131)

Second row leather seats have seatback recliners at the
40% seating positions. Raising the lever allows the seat-
back to be reclined an additional 11 degrees. To fold the 40% seatbacks, fully raise the lever on the side
of the seat to release the seatback. The seatback can now
be folded into the down position for use as a cargo floor,
or the seat can now be tumbled forward to allow access
to the rear of the vehicle.
