If I didn't tender, here in the Midwest when it is too Hot or too Cold after about 6 to 7 days the BMW when entering vehicle provides me a message that it shut down auxiliaries and furthermore cannot due remote venting, etc..
When I do drive it is not long and far enough for alternator to charge battery. I get home and battery is usually at 25 to 40 percent after 100 percent charge pre drive.
