What does this button do… anyone know?

Does it set your destination to Russia?

This means you should finally open that plastic-wrapped manual in the glove box.

Looks like a lane assist button, at least it’s similar to the one in my Kona.

That button wouldn’t be on the rearview mirror like the person who posted this showed.
