Where is the rearview mirror heating switch located on the BMW 1 Series?
2 Answers
BMW 1 Series' rearview mirror heating button is located on the control panel, featuring a square frame with three upward curved arrows inside. Pressing this button activates the rearview mirror heating function. Principle of rearview mirror heating: Both side mirrors are equipped with heating elements (electric heating films). During rainy or snowy weather, when the driver activates the rearview mirror heating function, these heating elements quickly warm up to a set temperature (typically between 35-60°C) within minutes, effectively defogging and defrosting the mirrors. The rearview mirror heating button icon should be distinguished from the front windshield defroster button: A sector shape containing three upward curved arrows represents the front windshield defroster, while a square frame with three upward curved arrows indicates the rearview mirror heating function.
I used to operate the rearview mirror heating switch on a BMW 1 Series, and its location is actually not complicated. It's typically integrated into the air conditioning control panel, sharing the same button with the rear windshield defroster, marked by a rectangular icon with wavy lines. Pressing this button automatically activates the mirror heating system to help clear fog or ice. I recommend using it frequently during rainy or winter driving to enhance visibility and prevent blind-spot accidents. BMW's design is quite convenient as the button is located on the driver's side of the center console, eliminating the need to navigate through extra menus—it's both ergonomic and hassle-free. However, note that it's not an independent switch; activating it also turns on the rear window heating, so don't confuse the functions. Regularly check if the button responds properly to avoid malfunctions affecting safe driving. In short, a simple press ensures peace of mind while driving, making it worth confirming before each trip.
