Can Audi Mirror Heating Not Be Used in Summer?
2 Answers
Audi mirror heating function can be used in summer but requires the temperature to be below 20 degrees Celsius to activate. Here is relevant information about car mirrors: 1. Function: While driving, mirrors help observe road conditions behind the vehicle. If they become blurred or unclear, it can affect driving safety. There is a mirror adjustment knob on the left front door, with an icon indicating the vehicle has mirror heating function. The rear window heating symbol uses heating wires to remove fog or frost on the rear window. 2. Automatic heating conditions: (1) The mirror adjustment knob is set to the heating position. (2) The external air temperature is below 20℃ (the external air temperature is measured by the outside temperature sensor, not the temperature displayed on the instrument cluster).
I also wondered about this when I first drove the Audi A6L. The rearview mirror heating function actually depends on the ambient temperature. Audi's design logic is to activate the heating system only at low temperatures to prevent the mirror surface from icing up. In summer, when temperatures generally exceed 20 degrees, the heating function automatically goes dormant. Honestly, using the heating function in hot weather isn’t really necessary, as high temperatures might damage the mirror’s coating. Once during heavy rain, I tried manually activating it, and the dashboard immediately displayed a temperature warning. For rainy days, I recommend keeping a chamois cloth handy to wipe the mirrors or applying a special water-repellent coating—water droplets will roll right off, which is super convenient. Also, be careful not to use a high-pressure water jet directly on the edges of the mirror when washing the car, as the heating wires are hidden there.
