Here is the method for connecting jumper cables: 1. First, attach the red clamp of the jumper cable to the red positive terminal of the "dead battery" vehicle. 2. Then, attach the other end of the red cable to the red positive terminal of the "donor" vehicle. 3. Connect the black clamp to the black negative terminal of the "dead battery" vehicle. 4. Next, connect the black cable to the black negative terminal of the "donor" vehicle. 5. Start the engine of the "donor" vehicle first, then start the engine of the "dead battery" vehicle. Additional information: If the "dead battery" vehicle still fails to start, check if there is poor contact at the metal connections. After successfully starting the engine, remember to remove the jumper cables in the correct order to avoid potential short circuits.

What does 'excellent condition' mean for a car?

A vehicle that has been driven for two years with 60,000 kilometers and has not been involved in any accidents is referred to as an excellent-condition car. Here are the relevant explanations: 1. Original paint throughout: As normally understood, this phrase means the entire car retains its original factory paint, or at least all metal surfaces except the front and rear bumpers have original paint. The car may still have remnants of its original paint, and areas that have been repainted are indistinguishable to the untrained eye. 2. Original condition: 'Original condition' means the car's frame is intact and its sheet metal coverings (such as doors, hood, etc.) have not been removed. There is an emphasized term called 'original condition with original paint,' which normally means: not only has the car not been repainted, but its coverings have also never been removed.

Is there a regulation on the direction of the parked car's front?

There is no regulation on the direction of the parked car's front, but for convenience, it is recommended that car owners park with the car's front facing outward. Although the Road Traffic Safety Law does not explicitly mention that the front of the car must face a certain direction when parking, it clearly states that vehicles must not drive against the traffic and must follow road markings. Therefore, parking spaces on both sides of the road must be parked in the direction of travel, otherwise, starting the vehicle will inevitably result in driving against the traffic. Parking with the front facing outward facilitates vehicle rescue. Most cars have front-mounted engines, so if the vehicle malfunctions, there is more space for emergency repairs or jump-starting. When there is a fluid leak, parking with the front facing outward also makes it easier to detect, enhancing safety.

What does the SE button in the car mean?

The SE button in the car refers to mode switching. Here are the related explanations: 1. Economy Mode: In this mode, the vehicle reduces the fuel injection ratio, and the computer decreases the throttle opening to lower fuel consumption. However, the downside is reduced power performance. This mode is suitable for long-distance driving, such as on highways or national roads with constant speed driving. 2. Standard Mode: This mode uses the most standard driving plan, suitable for urban or rural road conditions. It offers a certain level of fuel efficiency while maintaining adequate power performance. 3. Sport Mode: This mode can be used on mountain roads or muddy surfaces. The vehicle does not prioritize fuel economy, focusing instead on power output, meaning the vehicle performs with greater strength.

What does the vehicle's range mean?

It refers to the maximum distance a vehicle can travel at a relatively economical speed with the remaining fuel in the tank. Below are relevant details: 1. Driving range: The continuous driving distance of a vehicle with a full fuel tank under certain road conditions, typically 300-500 kilometers for general vehicles, while military vehicles usually achieve 600-800 kilometers. 2. Hybrid vehicles: The maximum range supported by the battery is relatively short, generally not exceeding 10 kilometers, whereas pure electric vehicles can achieve a much longer range, up to hundreds of kilometers. 3. New energy vehicles: The range refers to the distance a vehicle can travel at a constant speed under ideal road conditions, wind speed, temperature, etc., on a single full charge. Hybrid vehicles and lead-acid battery vehicles (low-speed vehicles) have relatively shorter ranges.

Where to Apply for Driver's License Annual Review?

Driver's license annual review is processed at the local vehicle management office. Below are the specific details of the driver's license annual review: 1. Review Content: (1) Road traffic safety violations and accident handling records. (2) Physical condition. (3) Points for road traffic safety violations and participation in study and exams after accumulating 12 points. 2. Regulations: Drivers holding licenses for large buses, tractors, city buses, medium-sized buses, or large trucks must undergo an annual review at the traffic management department of the public security authority within thirty days after each scoring cycle, i.e., once a year. For small and micro non-operational passenger vehicles, the review is required every two years within the first six years, and annually thereafter.

Why Does the DMV's Network Frequently Malfunction?

Here are the relevant reasons: 1. System Updates: Like games, traffic management systems require updates, which can render the internal network unusable—this is a relatively common occurrence. 2. Auxiliary Website Failures: Some services depend on other auxiliary websites for processing. If these websites experience network issues, certain services cannot be reviewed. 3. Payment System Failures: Network transmission problems can cause the payment system to malfunction, preventing the associated driver management system from printing tasks. 4. Server Room Failures: If the server rooms of higher-level or provincial departments fail, this means driver management services cannot be completed. 5. Fiber Optic Cable Failures: With frequent urban infrastructure construction nowadays, signal fiber optic cables are often accidentally severed.
