The mirror heating switch for Mercedes-Benz is located on the center console, integrated with the rear window defroster button (rear key). The mirror heating function ensures that the mirror surface remains clear when driving in rainy, snowy, or foggy weather by heating the electric filaments embedded behind the mirror. Working principle of mirror heating: The working principle of electric mirror heating is very simple and cost-effective. It involves installing an electric heating element (heating film) inside the mirror panels on both sides. In rainy or snowy conditions, when the driver activates the mirror heating function, the heating element quickly warms up to a fixed temperature (usually between 35-60°C) within a few minutes. This helps defog and defrost the mirror surface, providing great convenience for the driver.

I've driven the Mercedes-Benz E300 for many years, and its mirror heating switch is actually quite easy to find—it's located on the air control panel on the center console. The specific position is that rectangular icon button representing rear window defogging. Pressing it simultaneously activates both the mirror heating and rear window heating functions, which is super practical in rainy or snowy weather. Mercedes designed it cleverly—no need to search for a separate switch, just one button does the job effortlessly. If you're unsure, after starting the vehicle, check if there's any prompt on the dashboard or simply press it to test—the mirrors will quickly defog with noticeable effect. Remember to turn it on in advance during wet weather to improve driving visibility and safety. If the heating doesn't work, it might be a button malfunction or fuse issue—just have it checked at a professional shop. Don't worry about locating it; that button is clearly visible at a glance on the center console.

It's cleverly integrated with the rear window defroster button, located in the air conditioning control area near the steering wheel on the center console. Easy to find when needed - just press it and the heated mirrors quickly clear fog, especially useful during winter frost. Mercedes' integrated design avoids panel clutter while maintaining simple operation.

The first time driving a Mercedes-Benz E300, I was a bit confused when looking for the rearview mirror heating switch, only to find out it shares the same button with the rear window heating button on the air conditioning panel—just press it once. The button is located on the center console with a small square symbol, designed straightforward without any fuss. Pressing it during rainy drives quickly clears the mirrors, saving the hassle of stopping to wipe them—really convenient. If the function isn't working, check if the button is damaged or if the vehicle settings have the automatic mode turned off. Mercedes simplifying this is a good thing, making it easy even for beginners to grasp. Remember, the button is positioned slightly to the right in the center of the console, within easy reach, ensuring a worry-free drive.
