Usage method of Volkswagen rearview mirror heating function: Both the rearview mirror heating function adjustment and the left/right angle adjustment can be controlled through the knob on the driver's side door. L adjusts the left exterior rearview mirror by turning the knob up, down, right, or left; R adjusts the right exterior rearview mirror by turning the knob up, down, right, or left; O indicates the exterior rearview mirror is folded out, the exterior rearview mirror heating device is turned off, and the exterior rearview mirror cannot be adjusted. The rearview mirror heating function refers to when the car is driving in rainy, snowy, or foggy weather, the rearview mirror can be heated by the electric heating wire embedded behind the mirror to ensure the mirror surface remains clear.
To use the rearview mirror heating function in a Volkswagen, I usually start by locating the mirror adjustment knob on the driver's door panel, which typically has a small icon resembling a curved square or wavy line. Simply rotate this knob to the heating position, and the function will automatically activate for defogging or defrosting. It's especially useful during rainy or foggy summer days or frosty winter mornings. Turning it on for a minute or two before driving instantly clears the view, eliminating the need to frantically wipe the mirrors by the roadside. Having driven several Volkswagen models, I've found this feature quite intelligent—it even activates automatically when temperatures drop. However, it's best not to leave it on continuously to avoid overheating and battery drain. During routine maintenance, it's advisable to check the knob's responsiveness to ensure it functions properly when needed. In daily driving, this small feature makes road observation safer and more convenient.
Using the rearview mirror heating function in a Volkswagen is really convenient, especially in cold or humid weather. I always sit in the driver's seat, reach directly to the left door trim panel, locate the rearview mirror knob, and rotate it to the position marked with the heating symbol—it's usually automatic. It works exceptionally well for snow removal. Last time I went out during heavy snowfall, the rearview mirrors were frozen, but they were clear within minutes after turning on the heating. Combined with the windshield defogging feature, it helps reduce fogging issues caused by temperature differences inside and outside the car, boosting confidence in nighttime driving. In practice, no complicated tools are needed; just a quick twist does the trick. Volkswagen's design makes life's little details more thoughtful.
