Where is the rearview mirror heating button on the Song Plus DM-i?

The rearview mirror heating switch on the Song Plus DM-i is a rectangular button with wavy lines next to the exterior rearview mirror adjustment button. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for frequent manual wiping and 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 power-adjustable rearview mirror control—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 dedicated adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature (typically between 35-60°C) within minutes, distributing heat across both side mirrors. As the temperature rises, water droplets on the mirror surface shrink due to evaporation, and fog gradually dissipates, effectively defogging and deicing the mirror. However, its effectiveness diminishes in heavy rain, with less noticeable results. Precautions for using the rearview mirror heating function: The heating function relies on electric heating wires embedded in the mirror, which consume significant power. Ensure the vehicle is running when using this feature to avoid draining the battery, which could prevent the car from starting. Other methods for defogging rearview mirrors include: Opening windows slightly to create air convection between the interior and exterior, reducing temperature differences and gradually clearing fog. Adjusting the car's air conditioning to blow warm air, which helps remove fog from the mirrors.

On the BYD Song Plus DMI, I'm quite familiar with the rearview mirror heating button because it's located right on the air conditioning control panel. If you can't find it, look for the button with an icon of a small mirror with wavy heat lines—it's usually bundled with the defogging function, positioned among the row of buttons below the central display screen. When I use it during rainy or foggy weather, the mirror defogs incredibly fast, significantly improving driving safety. The design is straightforward—just operate it directly after starting the engine, and combining it with adjusting the air conditioning fan speed enhances the effect. I find this feature highly practical in wet weather, saving me the hassle of manually wiping the mirrors. Plus, the electronic control is stable and doesn’t consume too much power. Just remember to keep the button area clean to avoid dust interference.

As a car enthusiast, the rearview mirror heating button in the Song Plus DMI is located in the air conditioning control area, marked with a mirror and curved lines icon. Pressing it activates the heating element. I often study such systems, which are integrated into the electronic control system, offering one-touch operation for defogging and defrosting with fast and safe performance. The position is well-designed for blind operation by the driver, effectively clearing rain-induced fog for better visibility and driving experience. For touchscreen versions, check the settings menu for related options. Remember not to leave it on continuously to avoid wasting power—normal usage is sufficient.
