Car rearview mirror adjustment methods are as follows: 1. Before adjusting the rearview mirror, adjust the seat and steering wheel position. 2. Adjust the center interior rearview mirror by aligning the horizon reflection in the center of the mirror and positioning the right ear reflection at the left edge of the mirror. 3. Adjust the left rearview mirror by centering the horizon reflection and positioning the left side of the car's body reflection to occupy 1/4 of the right side of the mirror. 4. Adjust the right rearview mirror by positioning the horizon reflection at 2/3 of the mirror's height and placing the right side of the car's body reflection to occupy 1/4 of the left side of the mirror. Correctly adjusting the rearview mirror is not about reducing blind spots but ensuring a more favorable visible field of view for driving.

I remember when I first started driving, I always struggled with adjusting the rearview mirror properly, but now I've figured out some tricks. Before adjusting, make sure you're seated firmly in the driver's seat with your back against the chair and your head resting on the headrest—this posture simulates actual driving conditions. Gently grab the edge of the mirror and move it slowly without applying too much force to avoid damaging the bracket. My habit is to position the mirror so the entire rear window is visible, with just a bit of the sky and the edge of the rear bumper in view vertically. Horizontally, ensure both edges of the rear window are framed to minimize blind spots. After adjusting, test it by driving a few dozen meters and checking if vehicles behind you move smoothly in the mirror. If they suddenly disappear, the blind spot is too large and needs fine-tuning. In rainy weather, check more frequently as fogged-up rear windows can obstruct visibility. Many people set the mirror too high or too low, missing vehicles behind them—this is especially dangerous during highway lane changes. One more detail: for cars with electric adjustment buttons, avoid holding them down continuously to prevent motor burnout; instead, use short, repeated presses.

As a fresh graduate from driving school, adjusting the rearview mirrors was one of the first basic operations I learned. The instructor taught me to first adjust the seat to a comfortable position, hold the steering wheel at the three o'clock position with my right hand, and slowly push the mirror from behind with my left hand. The key standard to remember is to position the horizon in the center of the mirror, so that the lights from vehicles behind won't be glaring. When adjusting left and right mirrors, it's best to pull over and do it while turning your head to observe the actual rear window coverage. I prefer to have the mirror edges just reveal the two ends of the rear window. In city driving, it's especially important to repeatedly check—if more than a quarter of the rear window is blocked, you need to readjust. Tightening the locking screw properly is crucial; once I forgot to lock it, and the mirror flipped down on a bumpy road, nearly causing an accident. I recommend reconfirming the mirror settings every month or before long trips—safety details should never be neglected.

I used to complain about the large blind spot on the right rear side when driving an SUV, but later realized it was due to incorrect rearview mirror adjustment. The adjustment method is actually quite simple: sit upright, gently support the bottom of the mirror with your fingers, and push it upward or downward until you can see the entire rear window. The key is to use it in combination with the side mirrors: the center mirror is responsible for the straight rear view, while the side mirrors cover the sides. When adjusting, use a reference point, such as positioning the distant horizon at the upper third of the mirror. At night, make sure the headlights of following cars don’t cause glare. Models with auto-dimming and automatic adjustment are much easier—just start the car, and they position themselves. Newer models even allow angle adjustments via a mobile app, though my older car requires manual tweaking. By the way, for cleaning, a soft cloth with alcohol works best to remove oil stains from the mirror surface.
