The method to turn on the headlight cleaning device of BYD Tang is: 1. The headlight cleaning button of BYD Tang is located on the left side of the driver's dashboard. Before using the headlight cleaning device, you need to turn on the headlights first; 2. After turning on the headlights, press the cleaning button, and the nozzle under the headlights will spray high-pressure water to clean the headlights. The headlight cleaning device has a water outlet under the headlights, which can clean the dust and dirt on the headlights at any time to ensure sufficient lighting. Taking the 2021 BYD Tang as an example, it is a mid-size SUV with a body size of 4870mm in length, 1940mm in width, 1720mm in height, a wheelbase of 2820mm, a fuel tank capacity of 68 liters, and a curb weight of 1895kg.

When I first got my BYD Tang, I also spent quite some time figuring out how to use the headlight cleaning function. It’s actually very simple: first, make sure the headlights are turned on, like after starting the car at night. Then, operate the windshield wiper stalk—the lever on the right side of the steering wheel—by pulling the windshield washer switch. At this point, the cleaning fluid will also spray onto the headlights, automatically cleaning them. The design of the BYD Tang is very smart; it activates this linkage when the headlights are on without requiring any additional settings. I find it especially useful during rainy days or when driving on dusty roads, as it keeps the headlights clean promptly for safer driving. I’ve also developed a habit of regularly checking the washer fluid level. If it’s too low, I quickly top it up with purified water and cleaning agent to keep the nozzles clear. Don’t forget to test it once a month—it saves money and hassle, avoiding unnecessary trips to the repair shop due to clogging.

As a hands-on car enthusiast, I find the operation of the BYD Tang's headlight cleaning system quite straightforward: just activate the washer switch while the headlights are on, similar to how you spray water to clean the windshield. The key is that the headlights must be turned on; otherwise, the cleaning only targets the windshield, not the headlights. During use, I've picked up a few tips, such as activating the lever multiple times if one cleaning isn't enough, but avoiding excessive frequency to prevent rapid fluid consumption. For maintenance, I regularly check the nozzles for blockages, gently cleaning them with a toothpick to prevent dirt buildup. If any abnormalities occur, it might be a fuse issue or wiring fault, requiring a manual check and replacement. Overall, this system is highly beneficial for daily driving, especially after long trips, as it helps maintain headlight brightness for improved visibility and safety.

After years of driving, I find headlight washers crucial for safety. For instance, on the BYD Tang, you need to first turn on the headlights, then press the windshield washer button, and the system will automatically spray cleaning fluid. The operation isn't complicated, but ensuring the headlights are on is key. I often use it in foggy weather or after rain to promptly remove dirt and avoid obstructed vision. I recommend making it a habit to check the washer fluid level and top it up when low to prevent dry running and pump damage, saving money and extending its lifespan.

While playing with cars, I was quite curious about the BYD Tang's cleaning system: it is triggered by the linkage between the headlights and the cleaning lever, and the principle is that an electric pump drives the liquid to spray out. The usage method is just two steps—turn on the headlights and operate the cleaning switch to try it. I found that BYD's design focuses on user convenience without being complicated, and it may also integrate with a smart APP to adjust some settings, although the manual recommends prioritizing manual operation for greater reliability. For regular maintenance, pay attention to choosing antifreeze cleaning fluid to prevent freezing in winter and ensure smooth operation. Personally, I think automotive technology is becoming more practical day by day.

In my experience, to activate the headlight cleaning function on the BYD Tang, you need to pull the washer lever while the headlights are on, and it will automatically start. Similar to many other models, I found it works well in maintaining bright headlights after trying it. Just be careful not to accidentally disable the function in the settings. If it doesn't work, check the manual to see if a reset is needed. For maintenance, it's recommended to regularly inspect the nozzles and pipes to prevent blockages that could affect daily use and ensure safe and efficient nighttime driving.
