When the Auto selection is pressed for heating is the air circulation supported with air conditioning even though the AC button is not pressed.
This was the case in my previous car.

AC comes on automatically when you press the Auto button. Even if you have turned it off already

The AC pump is a variable-load swashplate type, so it can vary the amount of pressure in the refrigerant and hence vary the load on the engine, which is why this system doesn't have an Eco mode, as it uses the car's drive mode dial setting to vary the strategy.

In the summer/interior set to cooler temps it can have a big MPG impact, versus the winter/interior set to warmer temps when it's less impactful for example.
