New car windshield washer fluid usage duration primarily depends on frequency of use. Simply refill when depleted, as there is no fixed refill cycle. Below are the specific functions of windshield washer fluid: Cleaning Performance: Windshield washer fluid is formulated with multiple surfactants and additives. Surfactants typically feature wetting, penetrating, and solubilizing properties, thereby achieving cleaning and stain removal effects. Antifreeze Performance: Significantly lowers the liquid's freezing point to prevent freezing, enabling rapid dissolution of frost. Anti-Fog Performance: Forms a monomolecular protective layer on the glass surface. This protective film prevents fog droplet formation, ensuring windshield clarity and unobstructed visibility. Lubrication Performance: Higher viscosity provides lubrication, reducing friction between wipers and glass to prevent scratches.

What to Do When the HAVAL H6 Sensor Door Handle Fails to Open the Door?

If the battery is dead, the car won't start, and the sensor system will naturally fail. In this case, simply recharge the battery. The battery in the sensor key usually lasts for about 2 years. If the battery runs out, you can only use the spare mechanical key inside the sensor key to open the door. Just place the sensor key near the sensor to start the car. Note that the location of the sensor varies between different car models. In such cases, you can only try moving around the car at different distances and angles. Additionally, you can press the unlock button while making a phone call.

What to do if the first gear of Changan CS55 is difficult to engage?

Fork looseness or severe wear and even deformation. At this time, the damaged fork should be repaired or replaced, and the fixing screws should be tightened. Wear of the positioning groove and positioning pin. Sometimes it gets stuck, and the positioning pin cannot slide out of the groove, causing difficulty in engaging gears or shifting. It should be repaired. Deformation of the shift shaft, making it difficult for the sliding gear to move. At this time, the shift shaft should be repaired or replaced. Incomplete clutch separation, or even slipping, causing the gears in the box to continue rotating during shifting, making shifting difficult. At this time, the clutch should be adjusted.

How to Solve Windshield Fogging?

Press the defogging button, turn on the air conditioning (A/C) switch, set the temperature to the lowest, and turn on the external circulation to remove fog. Both cold and warm air can be used to defog car windows, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving defogging. The method of using warm air to defog is the same as using cold air, but it's important to note that warm air should not be used for defogging on rainy days as it may initially worsen the fogging. Always use external circulation when defogging car windows. The reason for car window fogging: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside are different, the surface with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface in tiny droplets, forming fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on promptly, the exhaled air has high humidity, and the windshield will fog up quickly. In this case, turn on the air conditioning to blow cold air onto the windshield, using the dehumidifying function to remove the fog quickly. If the humidity is too high and the air conditioning is not effective enough, slightly open the window to rapidly reduce the humidity inside the cabin. Combining this with the air conditioning will yield faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, blow warm air onto the windshield to quickly raise its temperature and reduce the temperature difference between the inside and outside surfaces of the glass, preventing excessive fogging. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to remove all the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. Avoid setting the temperature to the coldest position, as prolonged defrosting may cause fogging on the outer surface of the windshield. Applying Anti-Fog Agents for Prevention: Spray a small amount of defogging agent onto the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed, effectively preventing water vapor from condensing into fog. This is especially useful in cold winters. Alternatives to anti-fog agents include dish soap, soapy water, glycerin, alcohol, or saline solution. After applying, let it dry and then wipe off any excess with a chamois or soft dry cloth. This will keep the windows fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not too heavy, open both side windows to create airflow between the inside and outside of the car, reducing the temperature difference and gradually eliminating the fog. The principle of this method is the same as using cold air from the air conditioning. However, the downside of opening windows is obvious—it cannot be used during rain, snow, on highways, or when the fog is heavy. Rear Window Heating: Most cars have a rear window heating function, though the button location may vary. Turn on the rear window heating switch, and the fog will disappear in about a minute.
