Under normal circumstances, the automatic transmission fluid (ATF) in a vehicle should be changed every two years or every 40,000 kilometers. Here are some specific details about transmission fluid: 1. Function: It ensures smoother gear shifting, cleans and lubricates the gear system, extends the lifespan of the transmission components, maintains normal transmission operation, and can also reduce fuel consumption to some extent. New transmission fluid contains fewer metal impurities, reducing transmission wear and thereby extending the overall lifespan of the transmission while preventing minor issues. 2. Classification: The main types currently in use include DEXRON, DEXRON-II, DEXRON-III (produced by General Motors), and ATF-F (produced by Ford).

Can the ETC card still be used after being removed?

The ETC device cannot be used when the card is removed. According to the "Rules for the Use of the Non-Stop Fast Passage System," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When the ETC card is inserted into the OBU device, there will be a prompt sound, indicating that the device is activated. Without the card inserted, the device remains in a dormant state and cannot recognize vehicle information when passing through toll stations. Therefore, the ETC cannot be used if the card is removed. ETC is a non-stop electronic toll collection system, also known as an automatic road toll system. It is a dedicated road toll method typically used on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks in the background. This allows vehicles to pay tolls without stopping at toll booths, all based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping, thereby minimizing pollution. Reduced wear and tear: Saves costs by minimizing frequent starts and brakes, lowering vehicle wear and fuel consumption. Improved efficiency: Theoretically, ETC lanes can increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, key city clusters should achieve interoperability of transportation smart cards, and the proportion of vehicles equipped with ETC should significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will promote ETC adoption for trucks and explore deeper integration of the ETC system with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

What is the correct way to warm up a car?

The correct method to warm up a car is: let it idle for about 1 minute, then drive slowly until the water temperature reaches normal levels. During slow driving, maintain a low speed and keep the engine RPM below 3000 to 3500, generally around 2000 RPM. Avoid stepping hard on the accelerator (except in special circumstances), as this can cause significant damage to various parts of the engine. This is because the lubricating oil or grease for various components can only fully circulate when the vehicle is in motion. Therefore, avoid idling for too long, and systems such as the steering, braking, differential, and suspension require some movement to adapt to working conditions. The primary purpose of warming up the car is to circulate the oil from the engine sump to all parts of the engine in advance.

How to Correct Direction When Reversing into a Parking Space?

Memorize the approximate positions of each reference point in your mind. To accurately identify these points, you must first adjust the seat and rearview mirror to fixed positions. Use the clutch to control the vehicle speed. If the speed is too fast, press the clutch down slightly; if the speed is too slow, release the clutch a bit. After completing the above two steps, aim for the reference point and turn the steering wheel decisively to the correct position. When about to enter the parking space, maintain a distance of 30cm between the wheels and the corner of the parking space. Continuously observe through the rearview mirror and make corrections if the distance is less than or greater than 30cm.
