What is the sign of rearview mirror blowing?

The symbol for the rearview mirror heating button is easy to identify, with three upward-curving arrows inside a rectangle (as shown in the picture below).

? ?This sign is the rearview mirror defrost function. This button area is used for rearview mirrors. The symbol on the left is very common and is used to adjust the angle of the rearview mirror. The one circled is the rearview mirror defrost/defogging function. The purpose is the same as heating the rear window glass, which is to heat the rearview mirror and remove the water vapor on it.

? Pay attention to distinguish it from the front windshield defrost button. The symbol of the front windshield defogging button is fan-shaped, so it is not difficult to distinguish. The symbols of other function buttons are not similar to the symbols of the rearview mirror heating, so there is basically no confusion.

? The rearview mirror heating button is usually set on the air conditioning control panel, and some models will be set on the electric rearview mirror combination switch, that is, on the door. When the rearview mirror heating function is turned on, the electric heater inside the rearview mirror will quickly heat to a certain temperature (usually 35-60°C) in a short period of time, and hot steam will emerge.

< p>1. During the rainy and snowy season, when you first get into the car, the rainwater brought in by the drivers and passengers and the gas exhaled by the people in the car will form a layer of fog that adheres to the windows and front windshield due to the large temperature difference between the glass inside and outside the car.

2. Fogging in the car is a very troublesome thing. Fogging on the side windows will delay the viewing of the rearview mirror, and fogging on the front shield will prevent the driver from seeing the road. Therefore, more and more people All vehicles are equipped with a one-touch quick defogging device.

3. Just press the button with the max symbol on the upper left side of the picture. After pressing this button, many models will turn the wind direction to direct glass blowing and automatically change to external circulation. The AC button will light up, indicating that the air conditioner compressor is started.
