C Max Question
I recently purchased a 2013 Ford C Max to flat tow behind my Thor Ace. I was trying to determine whether the mileage will go on to the vehicle when it is flat towed (which I'm guessing it will) or may...

DouglasC - After reading some of your previous posts talking about the Ford Fusion and the key position, I think I see where our 'disconnect' here is:
I thought you were turning key all the way to OFF position, which is impossible when tranny is in neutral. Thats not the case, though - You turn it as far as it will go, which is really not the OFF position, but just before it. Sort of between ACC and OFF.
I've thought about doing that, but have not, 'cause as I said before, we just don't know if Ford has other reasons why they recommend leaving it in ACC position that we don't know about.
One thing I do know for a fact: Whether its in OFF or ACC position, with the Fusion hybrid, power (active) braking stays on all the time. Sit in your Fusion with ignition off, and hit the brake pedal a few times. After a few times, you'll hear a motor kick on, for the active braking. That is going to draw down the battery, eventually, as your supplemental braking system engages the brakes. And, thats in addition to any power the brake system (brake buddy in your case) uses from the battery.
For that reason, even if I set the ignition switch like you do....I'd still want a charge line. Starting batteries are not meant to be drawn down like that. While you may not draw it down enough to notice any issues yet...You will shorten the battery's life, and get to replace it sooner. A charge line is MUCH cheaper than an untimely new battery for your Fusion. :)
