Yes, button turns off. Normal. As in normal stupid, I never liked it either. Both mine do it.
Kinda like Tempo, Contour, Focus, each car was the later replacement for the previous. I've got all 3. WHY on earth did they make the exterior doorlock unlock forward on one, then backward on the next, then forward again???? I have NEVER been able to memorize which way unlocks the doors. Irritating..........
