There is only one way to properly set mirrors in any car........
For the driver side mirror, roll up the window and press your head against the glass. Adjust the mirror so that you can just see the edge of the car. For the passenger side mirror, place your head in the center of the car (directly behind the inside mirror mount) and adjust the outside mirror so that you can just see the edge of the car. This is necessary even with convex (curved) mirrors where the image is distorted a little. When you’re in your normal driving position, you won’t be able to see the sides of the car but will be able to see other vehicles in the adjacent lanes. - See more at:
