I suggested moving the seat back manually with contols on side of seat to get out, then pressing memeory position 1 (for example) would return to driving position when you got back in to drive.
Your suggestion to program number "3" to a "exit" postion is brilliant, that should work good for you. Dealer's have ways to program smart acess keys to correspond to memory numbers, make sure that is NOT done. Have fun !
