The rearview mirror heating button on the Bin Yue is located in the central control area. It is the fifth button from the left in a row of buttons, with an icon of a rectangle containing three upward wavy lines. This button controls both the rearview mirror heating and the rear windshield heating. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog, eliminating the need for the driver to manually wipe the mirror frequently, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as the driver's side has a control button. Principle of the rearview mirror heating function: After rotating the knob, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature (usually between 35-60 degrees Celsius) within minutes. The heat is then distributed across the left and right rearview mirrors. As the temperature rises, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defrosting and defogging the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The rearview mirror heating function works by incorporating electric heating wires into the mirror, which consume a significant amount of power. When using this feature, ensure the car is running. Avoid activating it while the car is stationary to prevent draining the battery and potentially causing starting issues. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Crack open the side windows slightly to allow air exchange between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Using the car's air conditioning: Adjust the air conditioning to the appropriate setting to blow warm air for defogging.

When driving this car, I also figured out that the rearview mirror heating switch is actually hidden in the central control air conditioning panel. Take a look at the button area on the driver's side—there's an icon with a square glass and wavy lines, which is the same button as the rear window defroster. It's especially useful on rainy days or when fogging up in winter. Just press the button, and within three to five minutes, the water droplets on the mirror will evaporate completely. Two things to note: first, don’t keep it on for too long—the manual says exceeding 15 minutes might damage the circuit; second, if pressing it doesn’t work, remember to check the F21 fuse in the fuse box. After washing the car, I love using this feature to clear any residual water stains on the mirrors.

Last time my best friend borrowed my car, I specifically taught her how to locate the rearview mirror heating button—it's the square marked key next to the air conditioning knob. This design is quite user-friendly, located in the same area as the vehicle stability system switch. Remember to start the engine first when using it, otherwise the battery might drain easily. Once when I went out in drizzling rain, pressing it for about ten minutes made both mirror surfaces clear up nicely. If the button malfunctions, it's likely a fuse issue, and replacing it yourself is quite convenient. A reminder to everyone: the heating wire is quite delicate, so never scrape the mirror surface with hard objects.

Let me tell you straight: Look for the square button with three wavy lines on the air conditioning control panel, located closest to the steering wheel on the left side. You'll feel the mirror heating up within two minutes after activation - super useful in rainy weather. Here's a quick science lesson: This function works via an electric heating film that automatically maintains a constant temperature at 50°C. If it fails, first check the 7.5 amp fuse. Remember not to activate it immediately when mirrors are frozen below zero - wait for the car's heater to defrost them first for safer operation.
