Press the rear windshield defrost button on the air conditioning control panel to activate the exterior rearview mirror and rear window defogger, with the indicator light illuminating. The exterior rearview mirror and rear window defogger will automatically turn off after approximately 12 minutes. Below is an introduction to the heated rearview mirror function: 1. The heated rearview mirror function refers to the ability of the rearview mirror to be heated by electric heating wires embedded behind the mirror surface when driving in rainy, snowy, or foggy weather, ensuring a clear mirror surface. 2. The working principle of the electrically heated rearview mirror is very simple and not highly costly. It involves installing an electric heating element (heating film) inside the mirror lenses of both rearview mirrors. In rainy or snowy weather, when the driver turns on the heated rearview mirror function, the heating element rapidly heats up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius, thereby heating the mirror surface to remove fog and frost.









When driving my Emgrand GL, I frequently use the rearview mirror heating function, especially on rainy or snowy days—it's particularly handy. The activation button is usually located in the air conditioning control area on the center console, marked with an icon resembling a small rearview mirror combined with wavy lines, sometimes also labeled as REAR DEFOG. Simply press this button—no additional settings are needed. Once activated, the heating filaments inside the mirror start working, and it typically takes about two to three minutes to defrost or defog. However, be cautious not to leave it on continuously to avoid draining the or shortening bulb lifespan. I usually check it before driving, ensuring it functions well in bad weather, as clear rearview mirrors enhance driving safety. On extremely cold days when the mirror ices over, this feature can be a lifesaver.

The principle of rearview mirror heating is that the resistance wire generates heat when electrified. The design of Emgrand GL makes the operation very simple. I usually look for the button near the air conditioning panel in the car, which has a wave or water drop icon, and its position may be close to the air volume adjustment. After pressing it, the system automatically starts heating without manual temperature adjustment, and it will automatically turn off after running for a while to save power. I suggest confirming that the car is started before pressing the button, otherwise it won't work. In daily driving, this function is crucial in rainy or foggy weather, especially for maintaining clear vision during long-distance travel. If you can find the vehicle manual or app to check the details, it will be more reassuring.

I found the rearview mirror heating feature incredibly convenient after driving the Emgrand GL! The button is located either below the steering wheel on the left side or among the central control buttons, with an icon resembling a small glass pane with waves. Pressing it lights up to indicate activation. After turning it on, just wait a short while, and the fog will dissipate. I usually make sure to activate it on damp and cold days to avoid blurry mirrors, which is much safer than wiping them with a cloth. Similarly, other buttons in the Emgrand GL operate in the same manner—just be careful not to confuse them, such as with the air conditioning switch. It's essential to check this feature before heading out in rainy or snowy weather.

During the time I've used the Emgrand GL, the heated rearview mirror has been a great convenience. The operation is quite straightforward: locate the button with a wavy line icon in the air conditioning area below the dashboard, press it until the light turns on. I usually activate it on frosty mornings or during rain, and it takes about five minutes to take effect. In terms of safety, this feature ensures unobstructed visibility when reversing or changing lanes. is simple—just occasionally clean the mirror surface with a damp cloth to keep it responsive. Related discussions include winter vehicle preparations, such as adding antifreeze, but the heating button is handled separately.

Turning on the heated mirrors of the Emgrand GL is quite simple, and I often use it during travels. The button is located near the center console, marked with a wavy line or a small mirror icon. Press it and wait a few minutes for the defogging to complete. Additional context: This feature enhances safety during rainy or snowy driving conditions, helping to avoid collisions. I regularly check if the button is responsive. It operates similarly to other functions like the rear window defroster, but avoid prolonged use to save energy. With clear visibility in rainy or foggy weather, driving becomes more confident.
