How to Turn On the Headlight Cleaning Function?

[StJayce]

The method to activate the headlight cleaning function is as follows: First, turn on the headlights, then pull and hold the windshield wiper lever for a few seconds. This will initiate the headlight cleaning function, which sprays water to remove dirt and grime from the headlight covers. The water used in the headlight cleaning function is essentially windshield washer fluid. If the windshield washer fluid is low, the headlight cleaning function may not work, so it is important to replenish the fluid promptly. The headlight cleaning function is primarily used in vehicles equipped with xenon headlights. Xenon headlights offer advantages such as energy efficiency, high brightness, high color temperature comfort, and long lifespan. However, they also have a drawback: their higher color temperature results in poorer penetration in rainy, foggy, or snowy conditions compared to halogen headlights. If the headlight covers accumulate dust and dirt, the penetration becomes even worse, and some of the light is absorbed. Additionally, dust particles can scatter the light, making the headlight cleaning function particularly useful in such situations.
