How to heat the rearview mirror of Audi Q3?
2 Answers
When the temperature difference between the inside and outside of the car reaches 6 degrees, it will automatically heat up and remove the fog on the exterior rearview mirrors. Press the rear window heating button to activate it. It is mainly suitable for rainy, snowy, and foggy days, and can remove moisture or frost from the rearview mirror in the shortest time.
I've been driving an Audi Q3 for a while, and the rearview mirror heating function is actually quite simple to use. After starting the vehicle, locate the rear window defroster button near the center console—it's usually marked with a square icon containing wavy lines. A gentle press will automatically activate the mirror heating. It takes about 5 to 10 minutes to start working, quickly melting frost and fog, which is especially useful in rainy or cold weather, ensuring clearer driving visibility. Audi designed it this way because the rearview mirrors and rear window heating share the same circuit, saving space and reducing accidental operation. From personal experience, there's no need to keep it on all the time—just use it when needed, like during morning frost or while driving in the rain. Developing this habit helps avoid unnecessary battery drain. Remember to regularly check if the button functions properly; if the mirrors don't heat up, the fuse might be blown, and you'll need to visit a repair shop.
