I will be sitting still a lot today in the car with the heat on. I know my charge tends to go low to the two pink bars pretty fast. Do I need to worry about the car battery just going dead or will it kick in and recharge itself even if I am not moving?
Yes, if you are just sitting in the car, keep it in Ready with transaxle in P. When the battery gets to two pink bars, the engine will come on to recharge the battery, then cycle on and off as needed. The car may move slightly when MG1 starts the engine; this frightened my GF when I left her in the car with the AC on. She thought the car was going to take off.
