It does if you have the AC on “auto”. There’s also another UI element that displays “defogging limited by settings” if you make manual adjustments and it detects the need
I'll have to make sure I have it configured correctly and see how the car reacts next time. I've also not seen the "defogging limited by settings" warning; then again, the text is so small on the warnings I might have seen it but not been able to read it.
