The reasons for the BYD Qin dashboard displaying 'Please check the power system' are: 1. The low-voltage battery is dead; 2. There is a fault in the high-voltage power battery system; 3. There are fault codes in the engine electronic control system. Taking the BYD Qin New Energy 2020 model as an example, its body dimensions are: length 4675mm, width 1770mm, height 1500mm, wheelbase 2670mm, and luggage compartment volume 450l. The BYD Qin New Energy 2020 model has a total motor power of 100kw and a total motor torque of 180nm, matched with an electric vehicle single-speed transmission.

How to Handle Traffic Violations for Non-local Vehicles in Beijing?

Non-local vehicles committing traffic violations in Beijing can be handled either through the Traffic Management 12123 app or by visiting the local traffic police brigade. Below is relevant information: 1. Vehicles with violations cannot undergo annual inspection: Vehicles with outstanding violations are ineligible for annual inspection. All violations must be cleared before the inspection. When processing the annual inspection, the vehicle must have all required documents, which can typically be completed within one working day. Before visiting the vehicle management office, prepare the vehicle inspection certificate, vehicle credentials, and the issued inspection compliance label. 2. For violations with fewer than 12 penalty points: You can bring your driver's license, vehicle registration certificate, ID card, and a UnionPay card registered under the license holder's name to the traffic police brigade where the violation occurred or where the vehicle is registered to print the penalty decision. The point deduction can then be completed at a self-service terminal.

Is the Mercedes HOLD function the same as shifting to N gear?

Mercedes HOLD function is not the same as shifting to N gear. The following is a related introduction about N gear: 1. Function: N gear is mainly used during startup, towing, or temporary parking. N position refers to neutral gear. To prevent the vehicle from rolling on a slope, you must step on the brake when shifting to neutral. When the lever is placed in "N" gear, the power between the engine and the transmission has been cut off and separated. For brief stops, you can place the lever in this gear and pull out the handbrake lever, allowing your right foot to move away from the brake pedal for a short rest. 2. Usage: Short-term parking: When the vehicle needs to be temporarily parked for a short time, such as waiting briefly for someone, you can use N gear for parking. However, if the waiting time is too long, it is recommended to turn off the engine; Towing during a breakdown: For short distances, such as a few kilometers, towing with the vehicle in N gear is allowed. For longer distances, a flatbed tow truck must be used; Startup and parking: N gear can also be effectively used during startup and parking. For example, starting from N gear and shifting to D gear is much better than starting from P gear and shifting to N gear through R gear.

Will the Model 3 chassis be damaged if it gets hit?

The car is fine, so there's no need to worry. Here is some relevant information: 1. Solution: When designing a car, the chassis is built with a certain level of impact resistance. Drive the car to a repair shop and have the chassis thoroughly inspected. If the pipes are undamaged and only the steel plate has been scratched, applying some paint to prevent rust will suffice. 2. Precautions: Generally, the chassis of a car leaving the factory has some anti-impact treatment. However, severe impacts may cause damage to the front bumper, suspension, and exhaust pipe. The most concerning issue is bottoming out, which can damage the fuel tank, engine oil pan, and brake system oil lines.

What to Do When the Car Windshield Is Covered with Frost in the Morning?

In the morning, if the car windshield is covered with frost, the solution is to turn on the external air circulation and use the warm air from the air conditioning to heat the car. Here is some relevant information: 1. Reason for frost formation: The reason why the car windshield frosts is that after the driver leaves, residual heat inside the car keeps the windshield temperature higher than the outside. When water vapor or snowflakes in the air land on the windshield, they first melt and then freeze, forming frost. 2. Obstructed visibility: When there is frost on the vehicle's windshield, the car should not be driven long distances. It is necessary to park the vehicle by the roadside and remove the frost from the windshield. Only after the frost is cleared can the vehicle be used normally, as the frost can obstruct the driver's view.

What does autonomous driving level L0 mean?

Autonomous driving level L0 means the driver has full control over all driving operations, including steering, braking, and acceleration, with the vehicle only executing commands. Below is more information about autonomous driving levels: 1. L1 level: Can assist the driver with certain driving tasks, such as the adaptive cruise control (ACC) function found in many vehicle models, which uses radar to control the distance between vehicles and adjust speed, widely applied in many domestic models. 2. L2 level: Can automatically complete certain driving tasks and adjust the vehicle's state after processing and analysis. For example, Tesla's lane-keeping function falls under this level, controlling not only acceleration and deceleration but also the steering wheel, though the driver must still monitor the surroundings to ensure safe operation. 3. L3 level: At this level, the vehicle is controlled by a more logical driving computer, and the driver does not need to keep hands and feet ready. The vehicle can independently complete driving operations in specific environments, but the driver cannot sleep or rest and must take over when the AI cannot make accurate judgments. The recently released BMW X7 claims to have achieved this level of autonomous driving technology. 4. L4 level: The vehicle makes autonomous decisions without requiring any input from the driver, typically relying on real-time updated road data to support functions like automatic parking, platooning, and obstacle avoidance in real-world scenarios. 5. L5 level: The key difference from L4 is that no driver involvement is needed at all, enabling all-weather, all-terrain autonomous driving that can adapt to environmental and geographical changes, allowing the driver to focus on rest or other tasks.

Which letter indicates the maximum speed rating on a tire?

According to tire specifications, the speed rating indicates the maximum speed at which a tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. In recent regulations standardized for tire labeling, all speed ratings except the continuously variable Z rating include both speed symbols and load indexes in their usage instructions. The speed symbol on a tire, also known as the tire speed rating, refers to the maximum permissible speed allowed for use under specified road surface conditions, nominal rim diameter, and within a defined time period. On tires, the letter J represents 100 km/h, K represents 110 km/h, L represents 120 km/h, M represents 130 km/h, N represents 140 km/h, P represents 150 km/h, Q represents 160 km/h, R represents 170 km/h, and S represents 180 km/h. Additionally, T, U, H, V, and Y respectively represent 190 km/h, 200 km/h, 210 km/h, 240 km/h, and 270 km/h. ZR indicates speeds exceeding 240 km/h. Tires are primarily composed of polymer composite materials, and temperature increases accelerate rubber aging. When a vehicle travels at high speeds, the entire tire's temperature rises, leading to accelerated tread wear. Every tire has its designed critical speed. When high-speed driving reaches this speed, the tire exhibits a "standing wave" phenomenon, which is the tire's "critical speed." Continued use under these conditions may result in a risk of tire blowout.
