Davidwhy, jj2me, thanks for for your helpful answers. I assume that the car is smart enough (i.e. smarter than me) to switch itself from EV to auto or EV Later if i drive the car in EV mode until i am out of power. I found a belpful article that provides some advice too. http://www.mattford.com/blog/ford-ev-auto-now-and-later-modes-explained/ Now if i can just get over the dial shifter! Thanks again.
