How to use the L and R buttons next to the driver's seat?

[DylanAnn]

The usage of the L and R buttons next to the driver's seat is as follows: Press the button to L or R to adjust the position of the left or right side mirror. Below is an introduction to the side mirror: 1. Function: When there is an emergency ahead that requires sudden braking, observing the central rearview mirror can tell whether there is a car following closely behind, so you can appropriately ease the braking based on the distance from the front to avoid a rear-end collision. 2. Principle: The side mirror outside the car window is a convex mirror, which utilizes the principle of light divergence to expand the field of view, thereby better noticing the situation of vehicles behind. The image is the intersection point of the reverse extension lines of reflected light, which does not actually exist, so the image formed is a virtual image.
