how do i move the back seats
I believe there should be a lever underneath each seat which you can pull toward you to get the seat to slide forward and back. Warning: this will not alter the leg room much; just a bit. It's a nice feature to have, though. Best of luck! CarGrrl
Also, to get the backrest of the seat down pull the knob on top of the seat upwards, then pull the back down.
