What is the function of the rearview mirror heating?
1 Answers
The function of the rearview mirror heating is to keep the rearview mirror clear when it fogs up after rain, allowing the driver to indirectly see the situation behind and around the vehicle. It acts as a second eye, expanding the driver's field of vision and improving driving safety. Some cars have a knob on the driver's side door, which is used to adjust the angle of the left and right rearview mirrors. Turning it to the left adjusts the left rearview mirror, and turning it to the right adjusts the right rearview mirror. When the knob is in the middle position, the rearview mirror heating function is activated automatically. Therefore, it is important to turn the knob to the left or right to prevent the heating function from being continuously activated, which could affect the lifespan of the heater.
