Here is something I have been working on but have yet to find a consistant method with my CMax. When climbing a hill, one of the techniques recommended for my sons 2004 Honda Insight is to punch the throttle for as long as possible (speed, traffic etc.) in order to engage both EV and ICE. It works very well in his Insight but, as I said, I have yet to find a method to engage both manually with my CMax. Sometimes it works, other times no joy. Thoughts?
