In this tutorial, we learn how to adjust the mirrors in a 2010 Prius. The interior rear view mirror will dim automatically if it sense a glare coming into it. You can turn this function on and off by pressing the buttons on the mirror. There are also outside mirrors that have controls to the left of the steering wheel. Press the buttons to adjust the area the lens is at. There is also a defroster that will activate when you turn on the front or rear defroster. This will loosen any ice from the mirrors so you can drive better and more safely.
