How to Use the Mercedes-Benz Headlight Cleaning Function?
4 Answers
The usage of the Mercedes-Benz headlight cleaning function is to press the windshield cleaning button five times consecutively while the headlights are on. The Mercedes-Benz lineup includes models such as the Mercedes-Benz E-Class, S-Class, GLC, A-Class, GLS, and Maybach S-Class. Taking the 2021 Mercedes-Benz GLC as an example, it features a 5-door, 5-seat SUV crossover body structure. Its dimensions are: length 4729mm, width 1890mm, height 1602mm, wheelbase 2873mm, fuel tank capacity 66L, luggage capacity 580L, and curb weight 1840kg.
I've been driving a Mercedes for a while, and the headlight washing feature is quite practical. The operation is very simple: after starting the vehicle, turn the headlight switch to the on position, such as rotating it to Auto or On. Then, on the wiper control stalk on the right side of the steering wheel, gently pull or press it, usually to the first detent position, to trigger the washing system to spray cleaning fluid. The water stream directly sprays onto the headlight surface, removing dust and dirt. I was very excited the first time I used it—the lights instantly became much brighter. Note that you shouldn’t operate it while driving at high speeds; it’s best to use it when parked or at low speeds to avoid distraction. During regular maintenance, check the washing fluid reservoir to ensure it’s not empty, as this could damage the nozzles. Try this feature after rain or long-distance driving—it can significantly improve nighttime visibility and safety.
As a frequent Mercedes driver, I find the headlight washer quite straightforward to use. After turning on the headlights, simply operate the wiper stalk to activate cleaning - Mercedes' design typically requires just one pull of the stalk to work, with the cleaning fluid quickly washing the lens surface. I recommend activating it on smooth roads rather than bumpy ones. If the washer fluid isn't replenished promptly, the system might malfunction, so I always check the reservoir during car washes. This feature effectively prevents dirt buildup, especially after driving on rural roads where lights get dirty easily. Remember not to overuse it, as the fluid depletes quickly, affecting long-term functionality. Safety first - always maintain full concentration when operating with lights on.
I really like this washing feature when using the car. Simple steps: With the headlights on, move the wiper lever to spray and clean the headlights. I often try pulling the lever while waiting at red lights, and the effect is immediately visible. Remember to maintain the washer fluid level to avoid clogging issues.
