How do i let down the rear seats in 2003 gmc yukon xL

FYI- I'm taking a shot at this one based on my 2003 Montana so take it for what it's worth.
My van seats have a very small level on the drivers side of each seat. Pushing the lever down allows the seats to fold down while pulling the lever up allows them to recline. There is also a small ******** the back side of each seat which when pulled allows them to be folded down.
Hopefully your 2003 Yukon seats are similar to my 2003 Montana seats and this will work for you
