Does the Song Plus DM-i have heated mirrors?
4 Answers
The Song Plus DM-i is equipped with heated mirrors. The heated mirror switch is a rectangular button located next to the exterior mirror adjustment button, marked with wavy lines. Heated mirrors are particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog, eliminating the need for frequent manual wiping and reducing driving hazards. How to use the heated mirror function: There are generally two ways to activate the heated mirrors. One is combined with the electric mirror adjustment function—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 required, as there is an adjustment button on the driver's side. Principle of the heated mirror function: After pressing the button, the electric heater behind the mirror glass rapidly heats up to a fixed temperature, usually between 35-60 degrees, within a few minutes. The heat is then distributed across the left and right mirrors. As the temperature rises, water droplets on the mirror surface shrink, and fog gradually dissipates, effectively clearing the mirror. However, in heavy rain, the effect may diminish and become less noticeable. Precautions for using the heated mirror function: The heating mechanism involves electric heating wires embedded in the mirrors, 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 mirrors include: Opening windows slightly to allow air circulation between the interior and exterior, reducing temperature differences and gradually eliminating fog. Adjusting the car's air conditioning to blow warm air can also help defog the mirrors.
I specifically researched this during my test drive of the Song PLUS DM-i top trim, and the rearview mirror heating function is standard across the entire lineup. On rainy days, I deliberately tested it—pressing the fan-shaped symbol in the middle of the knob, and the water droplets on the mirror evaporated in just 3 minutes, making lane changes in the rain feel especially secure. However, it's worth noting that the defrosting effect in winter is slower than clearing rain, and the manual recommends not using it continuously for more than 15 minutes to prevent overheating. This is pretty much the same for all cars equipped with heating functions. The rearview mirror heating button is integrated with the front and rear defogger buttons, located on the left side of the air conditioning panel—it took me a while to find it when I first got the car.
A year-and-a-half owner reveals this feature is hidden in the AC controls. Locate the physical button with a square and wavy lines (some batches use touch controls instead), press to activate the red light. It's been my savior during recent stormy commutes – no more foggy rearview mirrors. Remember to manually clear snow before using the heating function in winter, as direct heating may damage the mirror. Northern drivers note: at -10°C+, heating takes 7-8 minutes to work, significantly slower than in southern regions.
The standard-equipped heated rearview mirror is particularly practical. The button is located on the air conditioning panel above the driver's left knee, marked with three arrow symbols. Press it during rainy weather, and the mirror surface will become clear in about five minutes, thanks to the heating element that removes fog. However, avoid using it immediately after washing the car, as the temperature difference may risk damaging the film. Its defrosting effect is reduced in winter—if the ice is too thick, you'll still need to use an ice scraper.
