How to Turn On the Rearview Mirror Heating in a 2021 BMW?
2 Answers
The rearview mirror heating function is not available in every vehicle, so you need to check if your car is equipped with it. Before using the rearview mirror heating, make sure the vehicle is in the started state or turn the key to the ON position to power on the rearview mirror heating. Avoid confusing it with the front windshield defroster. The switch in the green circle is the front windshield defogging button, while the switch in the red circle is the rearview mirror heating button. In rainy or snowy weather, press the rearview mirror heating switch, and the indicator light on the button will illuminate. The heating element will quickly warm up to a set temperature within a few minutes.
Turning on the heated mirrors on the 2021 BMW is quite simple. I often encounter foggy or rainy days when driving, making it hard to see the mirrors, so I need to use the heating function quickly to clear the fog. Usually, you can find the button near the rear window defroster, located on the climate control panel. The button is marked with a window or "REAR" symbol. Just press it, and the mirrors will heat up within a few minutes, quickly removing the fog. Some newer BMW models automatically activate the heating function in low temperatures, which is quite smart and saves you the trouble of doing it manually. Remember to turn it on in winter or before it rains—it significantly improves driving safety. If the button doesn’t respond when pressed, it might be a blown fuse or a system malfunction. It’s best to have the circuit checked at a 4S shop to avoid any issues.
