I guess I would have known about the sliding arm rest if I would have gotten a "full size" owners manual, corporate cost cutting at it's best, I got a "mini manual" that only covers certain features like the radio and several other things and I got a DVD that covered "certain" other things, no sliding arm rest. I don't know about you guys but I always enjoyed getting the "full size" owners manual that covered most things that bored most people, but at least you know all there is to know about your new purchase!
