The Baojun 730 is equipped with a rearview mirror heating function. The switch for the rearview mirror heating function in the Baojun 730 is integrated with the rear window heating button, located on the right side of the air conditioning screen. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rainwater or fog, eliminating the need for the driver to frequently wipe the mirror manually, 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—pressing the heating button will activate it. There is no need to manually adjust the angle, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass will rapidly heat up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius. The heat will dissipate from the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface will gradually shrink, and fog will slowly disappear, thereby heating the mirror and removing frost. If the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror. These wires consume a significant amount of electricity. When using the rearview mirror heating function, ensure the car is in an ignited state. Avoid activating the function while the car is stationary to prevent draining the car , which could leave insufficient power to start the vehicle. Other methods for defogging rearview mirrors include: Opening windows for airflow: Crack open the side windows slightly to allow air to flow between the inside and outside of the car, reducing the temperature difference and causing the fog to gradually disappear. Adjusting the car's air conditioning to the appropriate setting can also help defog the mirrors by blowing warm air.

I previously studied the configuration sheet of the Baojun 730. The rearview mirror heating function depends on the specific year and model. For example, the Luxury and Flagship models after the 2016 version are equipped with it. The button is located in the air control area, marked with a square and wavy line icon. It's particularly useful on rainy days—after turning it on, the water droplets on the mirror surface evaporate in about five minutes. However, the lower-end Comfort model might not have this feature. I recommend checking your car's manual or directly looking for very fine heating wire patterns around the edges of the rearview mirror. If you're still unsure, the safest way is to have a mechanic test it during your next service. After all, this feature can significantly improve driving safety during the rainy season in southern regions.

I drive a 2019 Baojun 730 manual transmission, and personally tested the heated mirrors. Remember last winter morning when there was frost, pressing the button with the heat symbol on the right side of the AC panel melted the frost in about ten minutes. This feature is usually linked with the rear windshield defroster, so be careful not to accidentally press the AC button when turning it on. Early models might only have this feature in higher trims, so I suggest you first check if there's a rectangular button with wavy lines in the AC control area. If you find it doesn't have this function, don't worry. You can buy a pair of heated mirror lenses online for around a hundred bucks and have an auto repair shop modify the wiring in half an hour—much more cost-effective than the factory option.

It really depends on the car model and configuration. For example, my neighbor's 2020 Baojun 730 Flagship version has it. The actual rainy-day effect is noticeable – water droplets start shrinking on the mirror surface within three minutes of activation. Operation is simple: after starting the vehicle, press the square heating button in the AC control area (next to the air circulation button), and the indicator light will show it's working. It's recommended to keep it on during winter to prevent fogging and frost. However, owners of lower-spec models shouldn't be disappointed – you can buy a pair of rain-proof films from Taobao for about 30 yuan, which also work well, though they need replacement every three months. If considering wiring modifications, it's best to consult a professional technician, as it involves electrical safety.

As a frequent long-distance driver of the Baojun 730, I can responsibly say: the rearview mirror heating is a lifesaver in rainy weather! My mid-range 2018 model came with this feature by default. The activation button is located at the top of the light control stalk on the left side of the steering wheel - it's the one with three wavy lines. When you notice fogged mirrors in the morning, just press it once, and the residual engine heat will quickly dry the mirror surface. However, be aware that aftermarket wide-angle blue mirrors might damage the heating layer - I learned this the hard way. New owners should specifically check this function during pickup and ask the salesperson to demonstrate it on the spot. Northern users should pay extra attention to this feature, as it eliminates the hassle of frequently wiping mirrors during snowmelt season.

According to the latest configuration sheet, the current Baojun 730 models have all removed the rearview mirror heating function, which is quite regrettable. However, most high-end models from 2016 to 2020 in the market still have this feature. Here's how to identify it: check if there's an independent button with a wave icon on the left front door trim panel, or look for a square heating button on the right side of the air conditioning panel. The mirror temperature can rise to about 50 degrees Celsius within five minutes after activation. Owners without this function can try a makeshift solution—before setting off, wipe the mirror surface with a mixture of dish soap and water to create a hydrophobic film. This feature is genuinely practical when driving on highways, especially during heavy rain when changing lanes without needing to crane your neck to check blind spots.
