Dead battery or poor battery contact. The time control module in the remote key malfunctioning can also cause the remote to stop working. After applying explosion-proof sun film to some cars' front windshields, the remote door lock may become unresponsive when attempting to unlock the car from the front. Normally, the original battery of a smart key can last about two years, but severe electromagnetic interference can also cause the smart key to malfunction. Replacing the battery of a smart car key requires caution. Any mistake can burn out the circuit board inside the key. Car owners are advised to have the battery replaced at a professional 4S shop whenever possible.

What does the curb weight of a truck mean?

The curb weight of a vehicle refers to its own weight. Below are relevant explanations: 1. Curb weight: It refers to the 'unladen weight'. Generally understood as the weight of a vehicle when fully equipped according to factory technical conditions (such as spare tires, tools, etc.) and with all fluids filled. Essentially, it is the weight of the vehicle when ready to drive without passengers (including the driver) or cargo. The gross vehicle weight (G) refers to the weight of the vehicle when fully equipped and loaded with passengers (including the driver) and cargo as per regulations. 2. Relationship: The relationship between curb weight and gross weight is: curb weight < reference weight < maximum gross weight. Additionally, the difference between the two is that the gross weight has a larger range. The gross vehicle weight range = curb weight + driver and passenger weight + luggage weight.

How Many Kilometers Should a New Car Have Before Driving on the Highway?

A new car should generally wait until after the first maintenance service, which is around 3,000-5,000 kilometers, before driving on the highway. This is because the initial oil used before the first service contains a significant amount of debris, and driving at high speeds with this oil can greatly increase engine wear and even cause abnormal damage. As a result, the car may not be in optimal condition after the break-in period. Additional tips for the break-in period: 1. Avoid hard braking: Hard braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It is best to avoid hard braking within the first 300 kilometers of driving. 2. Avoid overloading: Running a new car at full capacity during the break-in period can damage the components. Therefore, within the first 1,000 kilometers, the load should generally not exceed 75%-80% of the rated capacity. 3. Highway driving: Driving long distances during the break-in period increases the continuous working time of the engine, which can lead to increased wear. It is recommended to maintain a speed of 120 km/h with the engine RPM not exceeding 3,000. If the RPM exceeds 3,000, consider reducing the speed to keep it at or below 3,000 RPM. During long trips, take breaks at service areas for about ten minutes. 4. Avoid premature oil changes: The initial oil in a new car is specifically designed for the break-in period, with low viscosity, excellent heat dissipation, cleaning, and antioxidant properties. Some manufacturers even add grinding agents to aid the break-in process. Therefore, follow the manufacturer's recommended schedule for oil changes during the break-in period and avoid changing the oil too early.

How Long Can a Volkswagen Dry Dual-Clutch Transmission Generally Last?

Volkswagen's dry dual-clutch transmission has the following lifespan: The service life of Volkswagen's dry dual-clutch transmission depends on the vehicle's usage. If the car is regularly maintained, the dual-clutch transmission usually does not fail and can last for over ten years. Below is relevant information about the dry dual-clutch transmission: 1. Raw Material, Strength of Carburized Steel: The raw material used in Volkswagen's 7-speed dry dual-clutch transmission is carburized steel, which is considered the strongest material in transmissions. Under normal driving conditions, its strength ensures the transmission can last at least 20 years or 50,000 kilometers. 2. Friction Components, Wear Resistance of Powder Metallurgy: This wear-resistant material is used in aircraft brake pads. It is important to note that the temperature during aircraft landing and braking can reach around 1000 degrees Celsius. This wear-resistant material can also last at least 20 years in vehicles.
