2 Answers
The rearview mirror heating switch for the Mercedes-Benz E300L is located in the central control button area, combined with the rear windshield defogging function at the same switch. Pressing the corresponding switch will simultaneously heat both the rear windshield and the rearview mirrors. The rearview mirror heating function can evaporate water, snow, and frost from the mirror surface during rainy, snowy, or foggy weather, ensuring a clean and clear view. Taking the Mercedes-Benz E-Class 2021 E300L Fashion model as an example, its body dimensions are 5078mm in length, 1860mm in width, and 1484mm in height, with a wheelbase of 3079mm. It is equipped with a 2.0T turbocharged engine and a 9-speed automatic transmission.
I remember struggling to find the rearview mirror heating switch when driving the Mercedes-Benz E300L. At first, I searched all over the car, only to discover it was on the air conditioning control panel—the button with the rear window heating icon, which looks like a small square with wavy lines. Pressing it activates the automatic heating function for the mirrors, a clever design that saves space and is highly practical. On rainy days, I make it a habit to press it as soon as I get in the car, and within seconds, the mirrors clear up, significantly improving driving safety. When parking or washing the car, I usually wipe off any dust on the panel to ensure the icon remains clearly visible. If the button stops working, it might be due to a blown fuse or an electrical issue, so it's best to check it promptly to avoid problems in bad weather. This integrated feature makes operation smoother, though beginners might overlook it. Once you get used to it, it becomes incredibly convenient.
