I recently leased a 2017 Volt Premiere. I love the car but can't seem to get the hang of Hold mode. First, it's very hard to get the car into anything but Normal mode. I've tried holding the button down longer, letting go faster, you name it. It takes several tries before some magic combo achanges the mode. Then we went to put some gas in the Volt for a road trip. Apparently turning the car off reverts to Normal mode again, because once on the highway we noticed the electrical side depleting! Any tips? We live less than a mile from a freeway on ramp, so we would like to do the freeway portion in Hold mode and switch back to normal when we get nearer to our destination.
