Where is the rearview mirror heating switch for MG ZS?
2 Answers
The rearview mirror heating button for MG ZS is located at the far right of the air conditioning switches. The last button in the first row is for rearview mirror heating, which is the same button as the rear window heating. The icon is a rectangle with three upward wavy lines. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rainwater or fog, eliminating the need for the driver to manually wipe the mirrors frequently, thereby reducing driving hazards. Methods to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within a few minutes, typically between 35-60 degrees. The heat is then distributed to the left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface become smaller, and fog gradually disappears, effectively defrosting and de-fogging the mirror. However, if the rain is particularly heavy, the effect may be reduced and less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirrors, which consume a significant amount of power. When using this function, ensure the car is in an ignited state. Avoid activating the rearview mirror heating while the car is stationary to prevent draining the battery, which could leave insufficient power for starting the car. Other methods to defog rearview mirrors include: Opening windows for air circulation: Slightly opening both side windows allows air to flow between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting can also use hot air from the AC to defog the mirrors.
I've been driving the MG ZS for quite some time, and the rearview mirror heating doesn't have a separate button—it's usually integrated with the rear window defogger. There's a button on the dashboard with a rear window icon; just press it. In winter or rainy weather when fogging occurs, I press this, and the mirrors heat up to defog simultaneously—quick and hassle-free. It only works when the engine is running to avoid draining the battery. This design is quite smart, reducing buttons to prevent accidental operation and making daily use much more convenient. Last week during rainy highway driving when visibility was poor, I quickly pressed this, and the mirrors were clear in under two minutes. New owners unfamiliar with its location can check the owner's manual or ask fellow drivers—no need to visit a repair shop. In short: integrated with rear window heating, simple and reliable without hassle—don’t bother looking for a separate switch.
