Which Button Activates the Mirror Heating Function in Volkswagen?
2 Answers
The switch for Volkswagen mirror heating is located on the mirror adjustment control. Principle of Mirror Heating: The working principle of electrically heated mirrors is quite simple and not very costly. It involves installing a heating element (heating film) inside the mirror lenses on both sides. During rainy or snowy weather, when the mirror heating function is activated, the heating element quickly warms up to a set temperature, usually between 35-60 degrees Celsius, within a few minutes. This heats the mirror surface to remove fog and frost. Mirror Heating Function: The mirror heating function ensures that the mirrors remain clear when driving in rain, snow, or fog by heating the mirrors via heating wires embedded behind the lens. Volkswagen's mirror heating function has several restrictions. Besides needing to select the heating function on the door panel switch, the outside temperature must also be below 20 degrees Celsius for the function to activate. Therefore, if the outside temperature is above 20 degrees Celsius, the heater will not work even if the heating function is turned on. Not all vehicles are equipped with mirror heating, so it's important to check if your vehicle has this feature. Before using the mirror heating function, ensure the vehicle is running or the key is turned to the ON position to power the system.
I've been driving a Volkswagen Golf for several years, and I'd like to share some experience about finding the heated mirror button. Actually, it shares the same button with the rear window defroster, usually marked with a snowflake symbol or labeled 'rear window defrost' on the dashboard. When you can't see clearly in the mirrors due to rain or snow, pressing it will automatically heat the mirrors to remove fog. Don't worry about insufficient heating – it's designed intelligently to activate only in cold weather. Once during a heavy snowstorm in winter, I turned on the defroster before driving, and my visibility improved immediately. But remember not to keep it on all the time to avoid wasting electricity. If your model is different, I recommend checking the manual, as some newer versions integrate this function into the air control screen. A handy tip is to test the button after starting the car to ensure the best effect by activating it before the mirrors fog up.
