Here are the methods for adjusting rearview mirrors: 1. For the right-side mirror when adjusting the up and down position: The ground area should be larger, occupying about 2/3 of the mirror surface, while the left and right positions should be adjusted so that the car body occupies 1/4 of the area. 2. When adjusting the left-side mirror: The up and down position should place the distant horizon in the center, and the left and right positions should be adjusted so that the car body occupies 1/4 of the mirror surface. 3. When driving on multi-lane roads: Vehicles frequently change lanes, so it is essential to accurately observe the traffic conditions behind and to the side through the rearview mirrors at all times. If there is a vehicle approaching from behind, do not change lanes. If a vehicle is overtaking from the side or behind, temporarily refrain from overtaking the vehicle ahead.

When adjusting manual rearview mirrors, I first sit in the driver's seat with normal posture and eye level, then gently push the interior rearview mirror with my hand and rotate it until I can clearly see the entire rear window view, ensuring a clear sight of vehicles behind. Next, I adjust the side mirrors by pushing the mirror corner or support rod to position them so that just a small portion of my car's body (like the edge of the door handle) is visible, while most of the view covers the adjacent lane to minimize blind spots. Having driven for many years, I remember to regularly check mirror angles—spending a minute fine-tuning before long trips significantly enhances safety. If the mirror feels loose, the mounting screws might need tightening. By the way, cleaning mirror surfaces before driving in rain or at night is crucial to avoid glare. Also, ensure all adjustments are made with the engine off to prevent accidental starts.

Adjusting manual rearview mirrors is a blend of art and science. Once seated in the car, manually adjust the interior rearview mirror to face the center of the rear window, ensuring a clear view of vehicles behind. For the side mirrors, manually tilt the mirror surface to an ideal angle where you can just see a sliver of your own car's rear, while primarily displaying the outer road area to help eliminate blind spots. Some older models feature small handles near the door for mirror adjustment—apply gentle force to avoid damage. I always perform a pre-drive mirror safety check, testing the adjusted setup during a few minutes of actual driving to ensure comfort. If glare or limited visibility occurs, minor tweaks suffice. Angling the mirrors slightly is recommended for added confidence in daily driving.

Manual mirror adjustment is straightforward. First, get in the car and adjust your seat position properly. Then, use your hand to move the interior mirror until it aligns with the rear window, allowing you to directly see the back seats or the edge of the rear window. For the two exterior mirrors, push the edges with your hands to adjust them until you can just see a small portion of your car's body—this way, you'll have a clear view of the road beside you while driving. The whole process takes just a minute or two—don't overthink it. After adjusting, start the car and drive slowly for a short distance to verify that the visibility is smooth. The key is to regularly check if the mirror angles have shifted and ensure dust isn't obstructing your view.

When teaching my child to drive, I emphasize the importance of manually adjusting the rearview mirrors: After getting into the car and sitting upright in the driver's seat, first manually rotate the interior rearview mirror to reflect the full view of the rear window, ensuring no vehicles behind are missed. For the side mirrors, manually push the mirror surface to adjust it until you can see the tires or the edges of the car body, which helps detect objects in blind spots. Operate gently to avoid loosening the components, and remind them to regularly check if the mirrors have shifted. Developing this habit makes driving at night or on highways safer. These simple steps, when ingrained from a young age, can prevent major accidents.
