How to Adjust Rearview Mirror Position?

When adjusting the rearview mirror, pay attention to positioning the door handle at the intersection of the "midpoint vertically and the one-third line towards the car side." Additionally, adjustment methods vary across different car models, so ensure clear visibility of the vehicle's spacing and trajectory. Below are detailed instructions: 1. Left-side rearview mirror adjustment: For vertical positioning, the ground should occupy the center of the mirror surface. For horizontal positioning, aim to have the car body occupy 1/4 of the mirror while ensuring visibility of the lowest point where the rear wheel contacts the ground. 2. Right-side rearview mirror adjustment: Since the driver's seat is on the left, it's harder to monitor the right side of the vehicle. Therefore, for vertical positioning, the ground should occupy 2/3 of the mirror surface, with visibility of the wheel arch (the curved, protruding part above the wheel resembling an eyebrow). Horizontally, adjust so the car body occupies 1/4 of the mirror. 3. Central rearview mirror adjustment: Adjust the left/right position so the mirror's left edge aligns with your right ear in the reflection. Normally, you shouldn't see yourself in the central mirror. For vertical positioning, place the distant horizon at the mirror's center.
When sitting upright in the driver's seat, the trick to adjusting the side mirrors is to have the car body occupy about one-quarter of the mirror surface. The left mirror should show the road behind forming a straight line with the car body, while the right mirror should position the horizon in the upper center of the mirror. The interior rearview mirror should cover the entire rear window, avoiding any view of the seats. Remember to test lane-changing maneuvers after adjustment to ensure no blind spots. It's best to fine-tune the mirrors again when driving at night in the rain, as this can reduce accident rates in blind spots. I make it a habit to check the mirror positions every two to three months, as bumps can easily shift them.
The key to adjusting rearview mirrors is eliminating blind spots. For the left mirror, I position the horizon in the upper middle, while the right mirror only shows the taillight contour of my car body. The center interior mirror must be aligned with the direct rear view. Always perform a safety check after adjustment: first spot a car in the interior mirror, then turn to verify its position in the side mirror. If you must turn your head to see vehicles behind when changing lanes on highways, your mirrors aren't properly set. Tall SUVs require special attention to right-side blind zones – consider installing convex wide-angle mirrors. Dirty mirrors also impair judgment, so keep a chamois cloth handy for cleaning.
