BMW X3 rearview mirror defogging function description is as follows: 1. One-touch setting: The BMW X3's rearview mirror heating and rear window defogging functions are set on a single button. 2. Automatic heating: The BMW X3's rearview mirror heats automatically. When the rear window defogging switch is turned on and the temperature difference between inside and outside reaches 6 degrees, the rearview mirror will automatically heat up to remove fog. The heating function will activate when the button is pressed and automatically turn off after about ten minutes. 3. Function: For vehicles equipped with rearview mirror heating, when the rearview mirror frosts or freezes in winter, simply turn on the rear window defrosting switch, and the electric rearview mirror will start heating. The frost or ice on the rearview mirror will quickly disappear, providing great convenience for the driver.
The rearview mirror defogging feature in the BMW X3 is quite practical, and I use it frequently while driving. The mirrors tend to fog up easily, especially during rainy days or early winter mornings. I simply press the defogging button on the center console—the icon looks like a window with heat waves—and the system immediately activates the heating. The principle involves electric heating elements embedded in the mirror glass, which gradually evaporate the fog, quickly restoring clarity to the rearview mirrors. I usually turn it on after starting the car to avoid putting too much load on the battery. The operation is straightforward, integrated into the air conditioning system, and the button has backlighting for easy visibility. This feature is crucial for driving safety, ensuring a clear view of traffic behind. Don’t forget to periodically check if the button is responsive; if it stops working, it might be due to a fuse issue or aging wiring that requires maintenance. For prolonged use, it’s advisable to activate it intermittently to save power and protect the mirrors. The overall design is thoughtful, helping me maintain peace of mind while driving in harsh weather conditions.
