The rearview mirror is designed in the form of reflector. It is generally electrically controlled and can be adjusted in four directions. When using, adjust the driver's seat position, turn the LR button to the gear to be adjusted, l or R, and press the direction button to adjust the lens. When adjusting the lens, you can see the distance from the rearview mirror. You can see the car body in the triangle area, and the sight distance is as far as possible. When reversing, sometimes you need to look at the wheels. You can adjust the rearview mirror to go down, see the wheels, and then reverse. After reversing, you should turn the rearview mirror back in time.
