Where is the rearview mirror heating switch located in the BMW 5 Series?

The rearview mirror heating switch in the BMW 5 Series is located on the right side of the steering wheel, sharing the same button with the rain-sensing wiper function. Taking the 2021 BMW 525Li as an example, it is a mid-to-large-sized 4-door 5-seater sedan with body dimensions of: length 5106mm, width 1868mm, height 1500mm, and a wheelbase of 3105mm. The 2021 BMW 525Li is equipped with a 2.0T turbocharged engine and an 8-speed automatic transmission, delivering a maximum power of 135 kW and a maximum torque of 290 N·m. It features rear-wheel drive with front double-wishbone independent suspension and rear multi-link independent suspension.
When I first started driving the BMW 5 Series, finding the rearview mirror heating switch was quite a hassle. After some exploration, I discovered there wasn't a separate button; the design is quite intelligent—it activates in conjunction with the window defogging function, usually triggered automatically by sensors that detect temperature or humidity, requiring no manual operation. However, if you insist on manual intervention, I recommend checking the mirror adjustment knob near the driver's seat door armrest—turning it to the position with a heating icon will enable the function. Of course, this isn't the best practice as it might interfere with the automatic system. Here's a little tip: cleaning the rearview mirror surface of dirt before driving in rain or snow can enhance the heating effect, saving you the trouble of manual operation. If it consistently doesn't work, it might be a sensor malfunction or a blown fuse, so it's best to have it checked at a 4S shop. This ensures safe driving and prolongs the mirror's lifespan—I make it a habit to check before long trips. Remember, stay calm and look carefully; don't press every button on the dashboard like a beginner would!
