The 2021 Excelle is equipped with a heated rearview mirror function. The heated rearview mirror button is located on the air conditioning control panel, and the heated rearview mirror function is connected in series with the rear windshield defrost function. The symbol is a square frame with three upward-curving arrows inside. The heated rearview mirror 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 heated rearview mirror function: There are generally two ways to activate the heated rearview mirror 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. There is no need to manually adjust the angle, as the driver's side has an adjustment button. Principle of the heated rearview mirror function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within a few minutes, usually between 35-60 degrees Celsius. The heat will dissipate from both left and right rearview mirrors. Meanwhile, 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 rainfall is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the heated rearview mirror function: The principle of the heated rearview mirror involves adding electric heating wires to the mirror. These wires consume a significant amount of electricity. When using the heated rearview mirror function, ensure the car is in an ignited state. Avoid activating the function while the car is stationary to prevent draining the battery and making it unable to provide sufficient power for starting the car. Other methods for defogging the rearview mirror 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. Adjust the car's air conditioning to the appropriate setting to blow hot air for defogging.

I've been driving the 2021 Buick Excelle for two years now, and it definitely comes with the rearview mirror heating function. This feature is particularly useful in my daily driving, especially during rainy or cold weather. Just press the button, and the mirror quickly heats up to defog without the need for manual wiping. I recommend checking the icon on the center console; it's usually located alongside the defogging function. In terms of safety, this configuration makes lane changing and reversing safer by avoiding the risk of blurred vision. Buick has put thoughtful design into such features, including rear window heating, which collectively enhances the driving experience. During maintenance, be mindful of preventing wire aging or poor contact—simple upkeep can ensure long-term functionality.

The 2021 Excelle is equipped with a heated rearview mirror function, which I frequently use while driving. Its principle involves heating through built-in resistance wires in the mirror, connected to the vehicle's electrical system. Activation simply requires pressing a dedicated switch, usually located near the air conditioning controls. It effectively defogs, clearing water droplets in just one or two minutes, ensuring driving safety. When used in conjunction with the rear window defogger, the entire rear visibility becomes clear. Although it incurs a small cost, the power consumption is minimal and doesn't affect fuel efficiency. In daily use, keeping the contacts clean can extend its lifespan. Buick's attention to practical details in this model is reliable.

I tested the 2021 Buick Excelle, and the heated rearview mirror comes as a standard feature. It's very helpful when driving in the rain—just press a button to defog. This gives me more confidence when changing lanes and reduces the chance of accidents. Buick's safety features include this without any extra cost. It's easy to operate, even for beginners. I recommend regularly cleaning the contacts to avoid malfunctions. Highly practical and offers good value for money.
