Is there an easy way to tell if the HVAC system is heating or cooling? You can tell from the app by the color of the airflow arrows (red vs. blue), but I cannot see any way to tell from the screen inside the car. This may seem like an obvious thing but at moderate temperatures, it is not always clear. Also, the app tells you the actual cabin temperature but I cannot see that there is any way to tell this from the car itself. Am I missing something obvious here?
