Due to the need to press the accelerator pedal deeply for acceleration when starting the car, the throttle opening is large, and the engine intake volume increases, naturally requiring more fuel injection. The computer calculates the instantaneous fuel consumption using a higher fuel quantity and lower vehicle speed, resulting in a high value. High instantaneous fuel consumption does not necessarily indicate high average fuel consumption. Below is additional information: Instantaneous fuel consumption refers to the fuel consumption value of a car at a specific moment. From an individual data point perspective, the instantaneous fuel consumption value does not hold much significance, as it continuously changes under different driving conditions and driver operations. Connecting these values into a curve for observation is meaningless. However, monitoring instantaneous fuel consumption is important for understanding the engine's fuel consumption under various conditions.

Does the vehicle owner need to handle traffic violations in person?

Handling traffic violations does not necessarily require the owner to go in person. The following is a detailed introduction to the different situations and corresponding methods for handling traffic violations: 1. Penalty on the driver's license: All driver's licenses subject to penalties require the holder to be present to accept the penalty. 2. Vehicle violation ticket: Whether the vehicle violation ticket needs to be handled by the owner depends on the specific situation. If it is a violation ticket issued on the spot, the fine should be paid at the bank as soon as possible, and the owner can authorize someone else to handle it. 3. Violation notice: The violation notice can be handled in two ways. Generally, the notice shows violations captured by electronic surveillance. When the photo is taken from the front, the owner needs to handle it in person. When the photo is taken from the rear, only a valid official driver's license is required to handle it.

Is entering the left-turn waiting area during a red light considered running a red light?

Entering the left-turn waiting area in advance during a left-turn red light is not considered running a red light. The following is expanded information about left-turn red lights: 1. The left-turn waiting area is only for left-turning vehicles: When the green light for straight-moving vehicles in the same direction is on, although the left-turn light is red, left-turning vehicles are allowed to enter the "left-turn waiting area" at the intersection and wait until the left-turn signal turns green before proceeding through the intersection. 2. The left-turn waiting line is not a "stop line": If the signal lights for both the straight lane and the left-turn lane are red, all vehicles must wait at the previous stop line. 3. In the left-turn waiting area: When the green light for the straight lane in the same direction is on, vehicles in the left-turn lane must move forward to the waiting area and wait for the signal light to change before turning.

What is the reason for the error code displayed on the central control screen?

When encountering such an error code display, it is recommended to visit a 4S shop to read the fault code, as this is the only way to quickly locate the faulty part and determine the cause. There are many electronic systems in a car, and the circuits are very complex. It is impossible for car owners to repair them on their own, and they need to seek professional help at a 4S shop. More details are as follows: 1. If certain equipment or systems in the car malfunction, the computer will generate fault codes. These codes can help technicians quickly identify the faulty part and the cause, enabling swift repairs. During regular maintenance, you can ask the technician to use a diagnostic computer to read the fault codes, so any issues with the car's electronic systems can be promptly identified. 2. With the advancement in automotive manufacturing technology, mechanical systems in cars generally do not experience many faults, but electronic systems are highly prone to malfunctions. Once electronic systems fail, they are difficult to repair due to their complexity. 3. During regular use, if some connectors in the car become loose or have poor contact, it can also lead to electronic system failures. Therefore, it is important to pay attention to these details during daily use.

Does a new car have a green book?

No. Before a new car is licensed, it does not have a registration certificate (green book) or a driving license. You need to pay the purchase tax and take the vehicle qualification certificate to the vehicle management office to apply for them. The relevant information about the motor vehicle green book is as follows: 1. Definition: The green book of a car refers to the vehicle registration certificate. The vehicle registration certificate is a necessary property certificate for the vehicle. It is issued by the vehicle management department of the public security bureau after the completion of the motor vehicle registration. The vehicle registration certificate is kept by the vehicle owner and is not carried with the vehicle. When handling any vehicle registration such as transfer or ownership change in the future, the certificate must be presented, and relevant vehicle information will be recorded on it, equivalent to the vehicle's household registration book. 2. Notes: If the motor vehicle registration certificate is lost, missing, or damaged, it is considered a reissue of the motor vehicle registration certificate, and the motor vehicle must also be inspected. The vehicle management office shall confirm the motor vehicle, review the submitted proofs and certificates, and reissue or replace the motor vehicle registration certificate within one day from the date of acceptance. For motor vehicles registered before the implementation of the motor vehicle registration certificate that have not applied for it, the motor vehicle owner can apply for the motor vehicle registration certificate from the local vehicle management office. However, if the motor vehicle owner applies for changes, transfers, or mortgage registration, the motor vehicle registration certificate must be applied for from the vehicle management office before the application.

What is the Xin Hua Xing?

The Xin Hua Xing is the imported version of the Mercedes-Benz GLS450. Below are some relevant details about the Mercedes-Benz GLS450: 1. Exterior: The Mercedes-Benz GLS450 features a very imposing appearance. The large three-pointed star emblem on the front grille, paired with the dual horizontal bars, gives it a highly recognizable look. The flat front headlights are sharp and striking, while the side and rear profiles exhibit a rugged and muscular styling, presenting an overall harmonious and natural aesthetic. 2. Interior: The cabin retains the familiar Mercedes-Benz family design, with a 12.3-inch large LCD dual-screen setup that exudes a high-tech and luxurious feel. The choice of materials and craftsmanship is also quite refined. While it may not match the classical opulence of the S-Class, it certainly surpasses most models on the market. 3. Powertrain: It is equipped with a 3.0T inline 6-cylinder engine + 48V mild hybrid system, delivering a maximum power of 367 horsepower and a peak torque of 500 Nm. The transmission system is paired with a 9-speed automatic gearbox. The throttle response is lively, and the performance is outstanding. However, due to the large size of the vehicle, the driving dynamics are relatively poor—despite the strong power, it lacks agility.
