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.

As a veteran driver with over a decade of experience behind the wheel of a Volkswagen Passat, I find the positioning of the mirror heating button quite straightforward. It's integrated with the rear window defroster button, located near the center console area, featuring a snowflake or windshield symbol. When pressed, it activates heating not just for the rear window but also for both exterior mirrors to clear fog. I often use it on rainy mornings before heading out – the mirrors clear up quickly, improving visibility and enhancing the sense of safe driving. If the button malfunctions, it might indicate a blown fuse or wiring issues; don't ignore it and get it checked promptly. Remember to activate it only when necessary to conserve battery. Overall, Volkswagen's thoughtful design addresses common issues with just one button.

I think the mirror heating function is integrated into the rear window defroster button in most Volkswagen models. Pressing this button activates the circuit, allowing the built-in heating wires in the mirrors to warm up and eliminate condensation. It's simple to operate—just look for the snowflake icon button located in the center console area. It automatically activates in low temperatures with high efficiency, making it ideal for use during rainy, foggy, or snowy seasons to ensure clear, unobstructed visibility. For older models, the button might be separate, so check the control panel area to confirm. Don't forget regular maintenance like cleaning the mirror surfaces to enhance heating effectiveness.
