How to Turn On the Rearview Mirror Heating in a Car?

Method to activate the rearview mirror heating in a car: The rearview mirror heating switch is located on the rearview mirror adjustment knob. The icon for rearview mirror heating is a small rearview mirror symbol. Simply turn the adjustment knob to this small rearview mirror position to activate the heating function. Some cars do not have a separate rearview mirror heating switch; in such vehicles, turning on the rear windshield heating will also activate the rearview mirror heating. Rearview mirror heating is a highly practical feature, especially useful during certain adverse weather conditions. When encountering such weather, turning on the rearview mirror heating ensures that the driver can clearly observe the rearview mirror. The heating function will automatically turn off after a while, which is not a malfunction but a design feature to protect the internal heating wires of the rearview mirror.
I often help my neighbors adjust car settings, and the rearview mirror heating function is quite simple to activate on most models. Typically, the rearview mirror heating shares the same button with the rear window defroster, located on the dashboard control panel near the driver's seat, marked by a square with wavy lines or a similar symbol. You just need to press this button after starting the engine to activate the heating, which automatically works for a few minutes before turning off to clear fog and rainwater buildup, ensuring clear visibility. I love using this feature in rainy and damp weather because it quickly removes fog and prevents blind spots. The button location may vary across different car models—for example, in high-end vehicles, it might be integrated into the central touchscreen—but the operating principle remains the same. It's a good habit to check the button's responsiveness during routine maintenance to keep the rearview mirror clean and ensure safe driving.
