It will run just fine in gas mode. The gas engine will not charge the battery though. If you put it in mountain mode it will build up a 40% reserve in the battery and keep it at that level, which might not be a bad idea to just run it in mountain mode for the cold months, as that will keep more than the minimum SOC that the computer would notmally keep in the battery when unplugged. As long as you drive it regularly over those months when you can't plug in the engine will keep the charge from going too low.
