How to operate the X1 mirror heating?

After pressing the button, the electric heating pad behind the mirror glass will quickly heat up to a fixed temperature within a few minutes, generally between 35-60 degrees Celsius. The mirror heating function of the BMW X1 is intelligent. This function only starts working when the outside temperature is below 15 degrees Celsius, and it starts automatically.

I remember when I first drove the BMW X1, I often encountered foggy rearview mirrors during the rainy season. After researching for quite a while, I realized the operation was actually quite simple. After starting the engine, just look for the button with a fan and arrow on the central air control panel—that's the rear window defogger button. Pressing it not only heats the rear glass but also automatically heats both side mirrors. In about three to five minutes, the mirrors become clear, so even heavy rain won’t obstruct the view of vehicles behind. I usually turn it on in advance during humid weather or when frost forms in winter—it’s a habit that saves a lot of hassle. The feature is quite user-friendly, with no separate switch, making it less prone to accidental activation. For the newer X1 models with the iDrive system, you can even see the heating status indicator on the car’s display screen.

As an experienced car enthusiast who loves tinkering with vehicles, I'm quite fond of the X1's rearview mirror heating mechanism. At its core, it uses heating wires embedded in the mirror glass to defog, and its operation is entirely linked to the rear window defroster button—just press the rectangular icon with wavy lines in the climate control panel. This design is more logical than having a separate switch, as it ensures the mirrors heat up simultaneously with defogging during rainy conditions for better efficiency. I recommend turning it on immediately after starting the car, especially in sub-zero temperatures, to prevent thin ice from forming on the mirrors. If you notice slow heating, accumulated dust on the mirror surface might be affecting heat transfer—gently wiping it with a soft cloth can help. Also, avoid directly spraying high-pressure water at the heating module during car washes to prevent damaging the wiring.

When picking up and dropping off kids at school on rainy days, blurred rearview mirrors can be particularly dangerous. The X1's rearview mirror heating operation is especially user-friendly for homemakers like me: After starting the car, there's a physical button in the air conditioning control area with a square and an arrow symbol. Pressing it simultaneously activates the rear window and rearview mirror heating functions. In winter, I activate this function in advance before taking the kids, and within two minutes, the condensation on the mirrors dissipates. Note that the feature works best when the temperature is below 20 degrees Celsius, otherwise the automatic protection mechanism might not engage. It's advisable to regularly check this function during the rainy season. Just pressing a button ensures safe driving visibility, which is far more reliable than makeshift solutions like attaching small mirrors.
