Which button is for the rearview mirror heating function?

[MacColin]

Here is a detailed description of the rearview mirror heating button icon and its specific location: 1. The rearview mirror heating button icon is shaped like three upward-curving arrows inside a square frame. 2. There are generally two design types: one is integrated into the electric rearview mirror adjustment switch assembly. 3. The other is located on the air conditioning control panel. Here are the specific functions of the rearview mirror heating button: 1. After pressing the button, the electric heating pad behind the rearview mirror glass will rapidly heat up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius. 2. Warm air will emerge from both left and right rearview mirrors, while water droplets on the mirror surface will gradually evaporate and shrink as the temperature rises, and fog will slowly disappear, achieving the effects of heating the mirror, defogging, and defrosting. 3. During heavy rainfall, its effectiveness may decrease and become less noticeable.

I've driven several cars, and the position of the rearview mirror heating button varies by model, but most are located on the driver's side door panel or the center console. The icon is usually a rectangle with wavy or curved lines, representing the heating function. When pressed, the light turns on to indicate activation. This feature is very useful in rainy or snowy weather. Like last time when I drove in the snow and the mirror surface frosted over, pressing the heating button melted the frost in a few minutes, making the rearview much clearer. It only works properly after the engine is started, otherwise it will drain the battery. In some cars, like Toyotas, this button might be combined with the rear window defogger button, pressing it activates both heating functions. I recommend regularly cleaning the mirror surface to avoid dust affecting the heating efficiency. New car owners should check the manual to find its location. High-end cars may have automatic rain-sensing activation, but most manual buttons are near the door handle.
