Guidance needed! I just purchased a 2016 Smart Fortwo in the US&A. It is in excellent physical condition. It sat too long. I'll attach images of the dash warnings & door jam stickers. I am in New York. I was wondering if I should disconnect and/or remove the HV battery immediately or if that matters at this point. My biggest concern is that the temperature is dropping below freezing now that the winter is here. I don't want to waste time trying to learn by watching videos and searching for answers in the forums which I know are probably there. Guide me through the basics please. Thank you very much in advance.
