How to Eliminate Fog on the Outside of the Windshield?

Where is the air filter of Changan CX20 located?

The air filter of Changan CX20 is located inside the glove compartment on the passenger side. Open the glove compartment, push inward firmly on both sides to remove it, and you will see a black cover. Use a Phillips screwdriver to remove the small cross-head screw. After removing the cover, you can see the air filter. The functions of the air filter are as follows: 1. Filter dust particles in the air to prevent these pollutants from entering the car's evaporator and causing sludge that may block it. If the airflow from the vents noticeably weakens, it may be due to blockage. 2. The air filter also filters dust, mist, pollen, carbon oxides, and sulfides in the air. Since the filter contains activated carbon, it can absorb harmful gases and particles in the air.

What Happens If a Car Isn't Serviced for a Year?

If a car isn't serviced for a year, it can lead to abnormal wear and tear on the vehicle and engine, increasing the likelihood of vehicle malfunctions, accelerating engine wear, and raising maintenance costs. The hazards caused by prolonged vehicle inactivity are as follows: 1. Paint is prone to oxidation and aging: If the car is parked in an open-air parking lot, prolonged exposure to strong sunlight can cause the paint to fade, oxidize, and even crack. Automotive paint contains large amounts of resins, metals, and other substances that make it susceptible to oxidation. Especially under harsh environmental influences such as UV rays, acid rain, bird droppings, and dust, the paint is more likely to oxidize and age. Additionally, it's important to prevent scratches from other objects or vehicles, as well as intentional vandalism. 2. Severe engine wear: It's commonly believed that only frequently used engines suffer damage, but automotive experts reveal that prolonged inactivity can cause the lubricating oil film on the engine cylinders and piston surfaces to deteriorate due to exposure to oxygen and corrosive acids and alkalis in the air. This deterioration forms a gummy substance, losing its lubricating properties. The longer the vehicle remains inactive, the worse the deterioration becomes. When the engine is restarted, dry or semi-dry friction occurs between the cylinders and pistons, accelerating component wear. Moreover, starting resistance increases significantly, making it difficult to start, and prolonged inactivity can completely ruin the engine. 3. Tire deformation: Unlike bicycles, cars are made of heavy materials like steel, making them quite heavy. When a car is parked, its weight is supported by the four tires' contact points with the ground, causing localized compression and deformation. The longer the car remains inactive, the harder it is for the deformed areas to recover, altering the tire's weight distribution and creating uneven rolling radii, leading to imbalance. Once the car reaches high speeds, it can cause body vibrations, affecting ride comfort, accelerating tire wear, and introducing safety risks.

What to Do When There's a Sour Smell from the Car Air Conditioner?

Car air conditioners emitting a sour smell may be due to unclean air filters, dirty air ducts, or accumulated dust on a damp evaporator. Relevant explanations are as follows: 1. A large amount of impurities and dust can generate various molds harmful to human health. Besides timely cleaning of the evaporator (the air conditioning system is generally cleaned once a year, preferably before summer), it is also recommended to replace the air filter and clean the air conditioning system. 2. Skillful use of the air conditioner can effectively keep the evaporator dry, reducing the breeding of bacteria and mold. Timely replacement of the air filter is also a very effective method. Extended content: The function of a car air filter is to filter the air entering the car interior from the outside, improving air cleanliness. Common filtering substances include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust.

What Are the Consequences of Not Maintaining a Car?

The consequences of not maintaining a car include warranty voidance, paint corrosion, engine wear, oil degradation, filter clogging, tire aging, wiper hardening, wiring faults, and more. More detailed information is as follows: 1. From an external perspective, the car's paint is particularly vulnerable to damage, especially during the hot summer months when UV rays can corrode the paint. This can cause the car to lose its shine and appear aged. In more severe cases, the car's body may develop cracks. 2. If the air filter is not replaced in time, it can accumulate a lot of dirt, clogging the engine and causing ignition issues. Similarly, not replacing spark plugs after prolonged use can lead to ignition difficulties and even increased fuel consumption. 3. Tires will age, and if debris on them is not cleaned off, it can wear down the tires over time, potentially leading to blowouts.

How often should the transmission fluid be changed in a Passat?

The transmission fluid replacement interval for the Volkswagen Passat is every 50,000 kilometers. The methods for changing transmission fluid are as follows: 1. Gravity Drain: This works on the same principle as changing engine oil. After loosening the fastening nut at the bottom of the oil pan, the transmission fluid will automatically drain out through the drain hole. This is the most common and easiest method, but it doesn't completely remove all the old transmission fluid. Residual fluid often remains in mechanical grooves and recesses. 2. Machine Flush: New transmission fluid is added to a flushing machine, which connects to the transmission's fluid lines. The machine's function is to push out the old fluid with the new, achieving a complete replacement. This method cleans the fluid lines more thoroughly. The more new transmission fluid used, the cleaner the system becomes. A machine flush typically requires about 10-13 liters of transmission fluid and takes approximately 1 hour. 3. Oil Pan Removal: This method provides the most thorough replacement and cleaning, and also allows for cleaning or replacing the dirty filter. Removing the oil pan is a major task, and accordingly, the labor cost will be higher.

How to Use the Reversing Camera Correctly?

Correct usage of the reversing camera: When shifting into reverse gear, there are usually three colored auxiliary lines—red, yellow, and green—each representing different distances from the rear of the car. For example, the red auxiliary line indicates that when it touches an object, the distance is only 30 centimeters, and you should stop reversing immediately. The yellow auxiliary line indicates a distance of about 1 meter, allowing you to continue reversing but with caution and reduced speed. The green auxiliary line indicates a distance of about 2 meters, meaning you can reverse with confidence. Below are the steps and precautions for using the reversing camera: 1. When shifting into reverse gear, the reversing camera automatically activates. 2. The image displayed by the reversing camera is captured in real-time by the rear camera. However, due to distortion in the camera's imaging, it can easily lead to misjudgment of obstacle distances. Therefore, when assessing distance, it is best to rely on the more accurate feedback from the parking sensors. 3. Nowadays, almost all reversing cameras come with a reversing trajectory system. This system displays two dashed lines on the screen to simulate the wheel's movement path, which shifts according to the steering wheel's rotation. This feature allows for intuitive prediction of the wheel's trajectory, further enhancing parking safety.
