I found the little (hidden) button that partly folds down the seatback of the second row seat, but what do I do next to get the seat to SLIDE forward so someone (small) can climb into the third row? also, when I flip the seat back up, then sometimes it locks in a different position: either the seat is too far forward and more effort is required to get it to move back or sometimes the seatback is either too far reclined or too far forward. there must be something i'm missing. or is it timing? maybe i don't have the rhythm right?
