Method to activate rearview mirror heating in Q5: On the driver's side door, there is a rearview mirror adjustment button. The heating function is the middle position, marked by a rectangle with three upward wavy lines inside. Rotate the knob to the heating position, and the rearview mirror will automatically heat up based on the external temperature. The Audi Q5 is a dynamic and versatile SUV, measuring 4629mm in length, 1898mm in width, 1655mm in height, with a wheelbase of 2807mm. The Q5 perfectly combines the body design of a sports car, efficient power and responsive handling, the off-road safety performance of an SUV, and the excellent comfort and flexible interior space of a station wagon, inheriting many of the superior characteristics of the third-generation top SUV, the Audi Q7.
I didn't know how to turn on the rearview mirror heating function before, but later I found out it's actually linked with the defogging button. Most cars have a square icon with wavy lines on the center console—pressing it activates both the rear window and rearview mirror heating. Like when I often drive in rainy weather, after pressing the button and waiting three to five minutes, the water fog on the mirror surface slowly evaporates. But it's important to note that for cars with automatic air conditioning, it's best to turn on the external circulation first before pressing the heating button to prevent moisture buildup inside the car. One winter, I noticed the heating effect was slow, only to realize a protective film on the rearview mirror was blocking the heat—it worked much better after removing it. This feature is most useful when driving after snowfall, as it melts snow particularly quickly. Remember to touch the mirror surface after prolonged heating when parking; if it's too hot to touch, it's best to let it cool down before turning it off.
My car has been running for five years, and the rearview mirror heating button is located on the left side of the steering wheel. The icon looks like a mirror with a heat symbol, and when pressed, the red light turns on to indicate it's working. I tested it specifically during heavy rain recently—it takes about five minutes for the water droplets on the mirror to disappear after turning it on, but it takes longer if the mirror is frozen. It's recommended to start the engine before activating the heating function to avoid draining the battery. A mechanic once reminded me that a damaged heating strip in the rearview mirror can cause uneven heating—if you notice inconsistent effectiveness, the wiring should be checked. This feature is most useful during humid weather; when combined with the air conditioning dehumidifier button, it doubles the effect when the interior fogs up. However, avoid wiping the mirror with a cloth while heating, as high temperatures may cause the coating to peel off. In winter, it's best to defrost before turning on the heating, otherwise, the ice will melt slowly and consume more power.
