Thanks for your comment. I do use the app to remotely pre-warm the interior when we are driving through really cold weather. It was a godsent when it was 10 degrees outside. However, I had thought I could precondition the batteries using a very early version of the App I download back in May, way before my car was delivered. I can still visualize the whte lined rectrangle with the word "Precondition". I have recollections of using it a few times just to test it out and it worked fine. Hmmmmm, maybe I am losing my mind. I am in love with this car and just days after returning home from a 5 day 2400 mile trip, I am ready to do that trip again at the drop of a suggestion from my wife. I still use any excuse to run errands for her or even drive her to her meetings that she goes to. This is what it feels like to be in love!
