What Parts Need to Be Replaced During the Second Car Maintenance?

Can ETC be uninstalled after installation?

ETC can be uninstalled after installation. However, if the ETC device is removed by the user, it will become invalid because the ETC device has an anti-tamper feature. There is a small switch on the back of the ETC electronic tag; once it is peeled off the windshield, the internal switch will automatically shut off. Therefore, the vehicle's registration certificate must be presented to the ETC service provider for reactivation. ETC Billing Principle: There will be one or more ETC lanes on highways. Through microwave-specific short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, computer networking technology is used to conduct background settlement with the bank, achieving the goal of paying road and bridge tolls without stopping at the toll booth. All of this is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: The efficiency of vehicles passing through ETC lanes can theoretically increase by 2-3 times or more, making traditional ETC more updated, faster, 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, the interoperability of transportation smart cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the main indicators of the "13th Five-Year" comprehensive transportation development plan: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the adoption rate of ETC for passenger vehicles, efforts will be made to promote the use of ETC for trucks in the future. There will also be exploration of deep integration between the ETC system and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications.

What does 0W30 engine oil mean?

The number 0 before the W represents the viscosity at low temperatures. The smaller the number, the better the fluidity at low temperatures and the stronger the cold resistance. The number 30 refers to the viscosity at 100°C. The larger the number, the higher the viscosity and the better the high-temperature resistance. 0W30 engine oil means that the oil can flow normally at -35 degrees Celsius. The viscosity of engine oil should not be too high or too low. If the viscosity is too low, it will increase engine wear. If the viscosity is too high, it will affect the increase in resistance during engine operation, leading to reduced engine power and increased fuel consumption. When the engine is running, the oil forms a film on the surfaces of various engine components, which can reduce friction between them and lower the operating resistance within the engine. If the oil viscosity is too low, the oil cannot form a stable film, which will exacerbate engine wear. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity. 0W is -35°C; 5W is -30°C; 10W is -25°C; 15W is -20°C; 20W is -15°C; 25W is -10°C. The lower the number, the smoother the cold start of the vehicle. The second number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil can maintain its viscosity at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. Relatively speaking, the better the low-temperature fluidity, the smoother the cold start for the vehicle, and the better the protection for the engine. For fully synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. For semi-synthetic oil, the replacement interval is slightly shorter, requiring replacement every 7,000 kilometers or six months. When choosing engine oil, the following points should be noted: Engine oil should be selected according to the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oil should be preferred. Multi-grade oil is economical, long-lasting, and efficient, providing better protection for the engine. Due to its characteristics, multi-grade oil may appear darker and have lower oil pressure than conventional oil during use, which is normal. Since engine oil significantly affects the performance and lifespan of the engine, it should be strictly selected according to the specifications in the vehicle's manual, including the same series, service grade, and viscosity grade. The oil recommended in the vehicle's manual is based on the engine's performance and the temperature conditions of the sales region, providing certain guidance and leaving a considerable safety margin.

How to fold down the rear seats of an old C5?

Press the rear seat folding switch, pull the seat forward with your hand, and fold down the seat. You need to press the switch firmly. When folding down the left seat, only a single seat can be folded down. When folding down the right seat, two seats can be folded down simultaneously, which is called 2/3 split folding. When all three seats are folded down, it is called full folding.

How to Remove Dried Car Wax from Paint?

Dried car wax on the paint needs to be removed with alcohol scrubbing. Here are detailed information about car wax: 1. Definition: Car wax is a protective substance for automotive paint surfaces. It is a chemical material applied to the car's paint surface to protect it while also serving aesthetic purposes. Car wax primarily consists of natural or synthetic waxes, which penetrate into the paint's micro-crevices to create a smooth surface. 2. Function: Besides giving the vehicle's surface a glossy appearance, waxing effectively protects the paint. Additionally, it prevents static electricity generation during driving and shields against rainwater erosion.
