I've read and re read page 5 and all it says it that you can use either the manual or power seat adjuster to move the seat forward. So I guess you could call it a "quick" release if you quickly reach down and release the maual seat adjuster and move the seat forward.
What are you seeing on page 5 that indicates something different? I've gone over both cars trying to find something.
I know the S-10 exetended cabs way back in the mid 80s had a cable such that when you folded the seat forward it pulled on the adjuster level to release it so you simply folded the seat forward and slid it forward in one motion. Cool.
