Optional If your Buick has an electric mirror control, you'll find it on the driver's door. Convex Outside Mirror Your right side mirror is convex. A convex mirror's surface is curved so you can see more from the driver's seat. Move the switch to choose the right or left mirror. Press any of the four arrows to move the mirror in the desired direction. Adjust each mirror so you can just see the side of your car and the area behind your car. 107
