Water ingress in car headlights can be categorized into two types: minor water ingress and severe water ingress. Below are the handling methods for each type: 1. Treatment for Minor Water Ingress. For relatively minor cases of water inside the light, there is no need to worry too much. After the headlights are turned on for a while, the moisture will evaporate with the heat and be expelled through the vent tube. This generally does not damage the headlight or the electrical circuit. 2. Treatment for Severe Water Ingress. When there is a significant amount of water inside the headlight. Remove it, open the lamp cover, and let it dry. Then, inspect the headlight surface for any damage or potential leakage points. If any abnormalities are found, it is recommended to replace the headlight rear cover seal and the vent tube.

What are the reasons for abnormal noises after a vehicle wades through water?

There are many reasons for abnormal noises after a car wades through water, mainly including water ingress in the brake pads, foreign objects trapped between the brake pads and calipers, water ingestion in the exhaust pipe, and foreign objects lodged in the chassis. 1. Water ingress in the brake pads: If the car wades through shallow water and water splashes onto the brake pads, it is normal to hear a squealing noise when braking. In this case, simply drive normally until the water on the brake pads dries up. 2. Foreign objects on the brake pads: If the car wades through deep water, foreign objects such as plastic bags, paper, and mud in the water may get trapped on the brake pads, causing abnormal noises when braking. In this situation, the brake pads need to be cleaned.

Why Should You Never Change the Automatic Transmission Fluid in a Langdong?

For automatic transmissions in vehicles, the transmission fluid generally needs to be replaced every two years or every 40,000-60,000 kilometers driven. The specific requirements vary depending on the vehicle model, so please refer to the maintenance manual for details. Hazards of not changing the transmission fluid: Prolonged failure to change the transmission fluid can lead to damage in the transmission's shift control mechanism; cause abnormal wear on the gears and clutch plates inside the transmission; affect the normal operation of the transmission, resulting in damage to the transmission valve body. Over 99% of automatic transmission failures are caused by overheating of the fluid and the accumulation of impurities due to prolonged non-replacement of the fluid. Therefore, regular replacement of ATF (Automatic Transmission Fluid) is crucial for automatic transmission maintenance. Methods for changing transmission fluid: Loosen the drain screw at the bottom of the transmission to drain the old fluid before refilling, or directly remove the transmission oil pan to drain and refill the fluid. This method is more thorough than the previous one, as it removes impurities accumulated at the bottom of the oil pan. Alternatively, a smart circulation machine can be used for dynamic fluid replacement, which filters and cleans out sludge and impurities inside the automatic transmission through a circulation process.

Does the Electronic Parking Brake Engage Automatically?

Electronic parking brakes do engage automatically. Here's how electronic parking brakes operate during vehicle startup and shutdown: 1. Starting: In most vehicle models, when the engine starts, the driver fastens the seatbelt, and the doors are closed, applying slightly more pressure on the accelerator will automatically release the electronic parking brake. This function also applies to hill starts. For automatic transmission vehicles, with the electronic parking brake engaged, simply release the brake and press the accelerator to automatically disengage it. For manual transmission vehicles, the electronic parking brake will only release automatically when the clutch and throttle are coordinated to generate forward motion, preventing any rolling back. 2. Parking: Most vehicles equipped with electronic parking brakes will automatically engage the parking brake after the engine is turned off and the seatbelt is unfastened. Therefore, in most cases, no manual intervention is required. However, there are situations where manual operation is necessary, such as when parking on a slope or when the parking brake needs to be used to relieve stress on the transmission before parking. In these cases, the operation is the same as with a conventional parking brake.
