Adjust the mirror to the left
Tilt your head until you almost touch the head of the car, adjust the mirror to cover the rear quadrant on the left. At this time, the mirror is wider than the original
Adjust the mirror to the right
From the center of the vehicle (between the two front seats), look in the right rearview mirror and adjust until the entire right rear quadrant is visible.
Adjust the rearview mirror in the cabin
Adjust the rearview mirror in the cabin so you can see the rear window in the center of the mirror
Watch out for changing lanes
When you drive, pay attention that the vehicle passing from behind will start from the center of the rearview mirror. As it gets closer, it fades to the left (or right), and appears in the corresponding rearview mirror
Watch before changing lanes
When the mirrors are in place, they eliminate the blind spot behind the vehicle because there is a small amount of the area of view that overlaps the mirrors. At the same time, they also open up the field of view, an area where you need to turn your head to check when changing lanes.
