How to Use the Headlight Cleaning Function?
2 Answers
The method to use the headlight cleaning function is: 1. First, start the vehicle's ignition switch; 2. Turn on the headlights, then locate the windshield wiper spray control lever on the right side of the steering wheel; 3. Pull the control lever forward and hold it, which will cause the spray pump on the bumper to extend and spray windshield washer fluid onto the headlights. The headlight cleaning system is primarily used on vehicles equipped with xenon headlights, as xenon lights are known for their energy efficiency, high brightness, comfortable high color temperature, and long lifespan. Currently, most headlight cleaning systems use high-pressure spraying, and the cleaning effectiveness mainly depends on the distance between the nozzle and the headlight lens, the size of the water droplets, the contact angle, the spray speed, and the amount of fluid sprayed.
As an experienced car owner who handles basic maintenance myself, I find the headlight cleaning system quite straightforward to use: First, ensure the headlights are on after starting the engine, as many vehicles only activate the cleaning function when lights are illuminated. Locate the small button near the wiper control stalk or dashboard, press and hold it for several seconds until the nozzles spray water to wash the headlights. Never operate this while driving – always test it in a safe parking spot first. I've found that using this feature whenever the lights get dirty significantly improves nighttime visibility, especially on rainy or snowy roads. Remember to regularly check the reservoir level to prevent it from running dry when you need it most. The system is actually designed similarly to windshield cleaning – just be mindful not to activate it unnecessarily to avoid wasting fluid. I top up the cleaning solution quarterly to maintain smooth operation. Once you make it a habit, you'll appreciate how worry-free it keeps your drives – safety always comes first on the road.
