What is the Audi headlight cleaning function?

Audi headlight cleaning function is: it can clean the vehicle's front headlights. When the headlights of the vehicle are covered with dirt or dust, activating the automatic headlight cleaning function will clean the headlights, restoring their brightness after cleaning. Avoid using water other than soft water for cleaning: This includes hot water, alkaline water, and water with high hardness. These substances can damage the paint. Using hard water for cleaning will leave marks and a film on the surface of the car body after drying. Avoid using high-pressure water flow to wash the cab of the suction truck: Excessive water pressure can damage the car's paint surface. If there is stubborn dirt or mud on the car body, soak it with water first and then rinse it off. Use a dispersed water flow for spraying. Avoid adding random cleaning agents: Do not use laundry detergent, scouring powder, or inferior soap when cleaning. These cleaning agents contain alkali, which may wash away the oils in the paint and accelerate paint aging. Generally, no cleaning agents are added when washing the car.
I just learned about the Audi headlight cleaning function, which is essentially designed to solve the problem of headlights getting covered in mud while driving at night. It works by spraying cleaning fluid from nozzles hidden in the front of the car, combined with high-pressure water jets to directly wash away dirt on the headlights. Typically, when you turn on the headlights and use the windshield washer fluid a few times, this system automatically activates. For example, after driving on the highway in the rain, headlights can easily get splattered with mud, and this feature helps maintain clear and bright lighting, preventing obstructed vision and ensuring safety. My friend drives a Q5 equipped with this function, and he says it’s especially useful in snowy weather, as it eliminates the need to get out of the car to wipe the headlights manually.
As a frequent long-distance driver, I particularly value the practicality of Audi's headlight cleaning system. It operates on a similar principle to windshield wiper fluid spray but is specifically designed for headlights: high-pressure nozzles hidden in the front bumper spray a mixture of water and washer fluid from the side when activated, effectively removing dirt and dust from the lens surface. This feature proves especially useful during hazy weather or on dusty roads. I've noticed most luxury vehicles are equipped with this system, given that obscured headlights can reduce illumination range by over 50%, making it crucial for driving safety.
I checked the manual to understand this Audi feature: The headlight cleaning system uses precisely positioned nozzles within the bumper to spray cleaning fluid, keeping the headlights crystal clear. It activates automatically when you use the windshield washer, or can be operated separately via a dedicated button. The key advantage is its high-pressure water jet that instantly removes stubborn dirt from the lens, ensuring unobstructed light output. Particularly useful after driving in rain, snow, or off-road conditions, it prevents reduced illumination range caused by dirty headlight covers.
