E300L rearview mirror adjustment is located on the door armrest. Before adjusting the left and right rearview mirrors, you need to press the left and right rearview mirror selection control button, after which you can adjust the rearview mirror up, down, left, and right. Relevant information about the rearview mirror heating function is as follows: 1. Symbol: The rearview mirror heating symbol is a curved upward arrow combined with a rectangular pattern. The position of the rearview mirror heating switch varies among different models, but the symbols are generally similar. 2. Working principle: An electric heating plate (electric heating film) is installed inside the mirror of both rearview mirrors. In rainy or snowy weather, when the owner turns on the rearview mirror heating function, the electric heating plate will quickly heat up to a fixed temperature within a few minutes, usually between 35-60 degrees Celsius, thereby heating the mirror to achieve defogging and defrosting effects.

















I've been driving a E300L for several years and am quite familiar with the rearview mirror heating function. It's located on the center console, on the button with a snowflake or defrost icon. Pressing that button not only activates the rear window defroster but also heats the side mirrors simultaneously. This feature is particularly useful in winter when fog or frost obstructs visibility—just one touch restores clarity. I use it regularly while driving; the one-touch design is clever without any complicated steps. If you're not familiar with it at first, pressing it a few times will help you get used to it. Remember, safety comes first—clear visibility helps prevent potential accidents, especially in rain or snow. It's also convenient when the function activates automatically, such as when temperatures drop to a certain level. In short, it's simple to operate and thoughtfully designed.

I've tried it a few times on cold mornings before driving, and within minutes, the rearview mirror becomes clear, which is really great. Remember not to confuse it—sometimes the button is near the air conditioning controls. If you can't find it, don't panic; just check the vehicle manual or experiment with the buttons. After using it a few times, you'll get the hang of it, making driving safer and easier.
