I am a new i4 owner. I can't find the button to turn on heated side mirrors. Checked the manual, it's not mentioned at all. Does BMW i4 have this feature?

In prior BMWs, my side mirrors heated automatically based on the outside temperature.

I can't remember if it was the front defrost setting or the rear defroster.

Yes, and they turn on automatically. You can’t manually turn them on.

It appears to be handled automatically except when in Eco Pro mode.
Same with the sensors, they get covered in snow quicker in Eco Pro than in Comfort. That's my experience at least.
