In many places, the Model S Owner's Guide refers to your Model S being off. "If your Model S is already off..." What does that mean? Does that just mean the touchscreen/dash screens are off? What does "off" mean with respect to the Model S? (Surely it's not referring to "off off off off", in which the car does no battery temperature monitoring, etc.) In my eyes, the Model S has four interpretations of off, listed here in increasing degrees of off-ed-ness: Off: In Park. Off Off: Touchscreen/control panel screen off. Off Off Off: Battery is close to bricking...car has disabled all systems to save remaining battery and prevent bricking. Off Off Off Off: Model S is completely off, and no longer doing any sort of thermal management, battery cooling, etc. Thus the confusion .
