How do I properly install the third row seat back into the Uplander?

With the seat in its folded position, angle it approximately 8–10 inches (20–25 cm) from the floor and place the front hooks onto the front floor pins, then firmly push down on the rear of the seat to lock the rear latches into the rear floor pins. Verify the seat is locked by trying to raise it — the indicator pins should no longer stick out when properly latched. Then return the seatback to the upright position and push and pull on it to confirm it is locked. (Page 30-31)
