What Causes the Noise When Folding the Rearview Mirror?
1 Answers
Noise during rearview mirror folding is usually caused by insufficient lubrication of the torsion spring inside the mirror. You can disassemble the rearview mirror cover, spray lubricant on both ends of the spring, then manually fold and unfold the mirror to see if the noise disappears. Repeat the process of spraying, folding, and unfolding until the noise is eliminated. The functions of a car rearview mirror are as follows: 1. Observing the rear road conditions: When driving in China, you often need to change lanes based on road conditions. Before changing lanes, signal in advance, then observe the rear traffic through the interior rearview mirror to ensure safety before changing lanes. However, this might overlook the situation of the vehicle behind you. The central rearview mirror allows you to see if the rear vehicle has signaled or intends to change lanes. 2. Checking the rearview mirror during emergency braking: When an emergency situation ahead requires sudden braking, observing the central rearview mirror can inform you if there is a vehicle following too closely. This allows you to adjust the braking intensity based on the distance ahead to avoid a rear-end collision. 3. Judging the distance to the rear vehicle: Drivers should stay highly alert and constantly monitor the surroundings of the vehicle, especially the central rearview mirror. It helps judge the distance to the rear vehicle: when the rear vehicle's front wheels are just visible in the central rearview mirror, the distance is about 13 meters; when the grille is visible, it's about 6 meters; and when the grille is just out of sight, the distance is approximately 4 meters. 4. Observing rear passengers: While driving, you can use the central rearview mirror to monitor rear passengers, especially when children are seated in the back. This eliminates the need to turn your head to check, preventing potential accidents ahead from going unnoticed.
