Is it normal for the head restraint on the power driver's seat to move up when the seat is moved back but not move back down when the seat is moved forward? Also, is the restraint position supposed to be saved with the memory system? Mine returns the seat position correctly but ignores the head rest. And since I'm on the memory system... I've noticed the steering wheel returns to the right height but doesn't telescope back to the saved position. Is this all normal?
