The rearview mirror heating for the BMW 2014 525 model can be activated simply by turning on the automatic rain sensor switch. Below is an introduction to the BMW 2014 525 model: Exterior dimensions: The exterior length, width, and height dimensions of the 2014 525 series are 5047×1860×1491 (mm), with a wheelbase of 2888 mm. The new 5 Series is 66 mm longer than the previous generation. Powertrain configuration: The powertrain system of the BMW 5 Series has been further enhanced, equipped with a V8 engine from the 7 Series, delivering a maximum power of 245 kW/333 hp (6100 rpm) and a maximum torque of 450 Nm (3600 rpm). It has a top speed of 250 km/h and can accelerate from 0-100 km/h in just 5.9 seconds.

As a BMW owner who has driven several models for years, I recall the rearview mirror heating button on the 2014 525Li was located on the driver's side door handle, right next to the window switches. That button featured a small snowflake or defogger icon – just one press activated the heating function, quickly clearing fog and moisture. The design is ergonomic, placing it within easy reach of your left hand so you never need to divert attention from driving. Why did BMW position it there? Firstly, for rapid response during rainy conditions, and secondly, to avoid cluttering the center console with controls. It's incredibly hassle-free, especially during southern China's monsoon seasons – one gentle tap and the mirrors become crystal clear. I've also noticed that if it stops working, it might be due to a blown fuse or a dirty button needing cleaning. Overall, this feature significantly enhances driving safety, and it's wise to have it checked during regular vehicle maintenance.

My experience driving a 2014 525 over the years is that the rearview mirror heating function is located in the door control area. Specifically, there are several buttons on the door panel for adjusting the mirror angle, and one of them marked with a heating symbol or a small heat wave pattern is the one. After pressing it, the mirror surface will warm up slightly, and the fog will dissipate within half a minute—it's a real lifesaver in humid weather. BMW's design is simple and efficient, with direct operation that reduces accidental touches. It's most suitable for use during heavy rain or frosty conditions, as it immediately clears your vision. I recommend wiping the button during each car wash to prevent dust buildup. Once you get used to it, you'll find this feature quite thoughtful and a significant boost to safety.

As a novice driver, I was curious about the location of the rearview mirror heating in the 14-model 525, but it's actually quite simple to find. It's integrated into the door panel button area, where there's a button with a small snowflake or heating symbol—just press it to activate automatic defogging. The operation is quite intuitive; once activated, the mirror surface heats up quickly to remove moisture, so you won't have to worry about poor visibility of side traffic on rainy days. The functional design of this BMW is user-friendly, and the manual also recommends frequent use for safety.
