What the heck ?? Weird button

You'd know what they were if you lived in the northern states, or Canada.

 

Is this satire

 

The first time I saw a heated mirror was on a tractor, the kind that go down the highway. I wonder if heated mirrors originated on trucks and buses? Or did heated mirrors first show up on luxury cars?

 

We've had it on cars going back to at least the mid 90s. It worked with the rear window defroster. Since we don't have those . . .

 

How do people, especially in cold weather states, not know what this is? Also, a car salesman doesn’t know?! Wouldn’t it be common sense to look up any buttons you don’t recognize to see what they do?

 

Yup!

I read through the quick guide before I showed up to sign the papers and read through the OM in the first week while trying out all the stuff.

When it comes to expensive bits like the driveline, I don't want to risk $$$ on ignorance.
