Sorry if this has been covered i've been searching a bunch of threads and cannot find it. Is there an easy way to tell if you have heated mirrors or not? Like is there a button or light or something?

There is a button. There is also a little heater icon on the mirrors

 

Yes, it does have the cold weather pkg.... http://www.cars101.com/outback_archive95-97.html

On the 2000 there's a lighted (when on) pushbutton just below the four-way power mirror adjuster switch for the mirrors, on the driver's door console by the windor switches. Also, there's little wavy heat-representative lines in a small logo etched on each heated exterior mirror. I realize you got a '97 but some of the clues may be similar.

Same as my '96.
