When Can a New Car Be Driven on the Highway?

1 Answers

It is best to drive a new car on the highway after the break-in period. During the break-in period, the engine speed should be controlled at around 2,500 RPM, and the car should not remain in a single gear for too long. The speed and gear should be changed every few minutes to ensure that the gears are properly broken in and to prevent excessive wear on any single gear. Here are some methods to determine whether a car is new: Check the manufacturing date: The manufacturing date on the vehicle should match the date on the certificate of conformity, and it is usually difficult to alter. If the manufacturing date exceeds 15 days, the car is considered used. Inspect the brake discs: After driving more than 200 kilometers, brake pads typically leave noticeable marks on the brake discs. There is usually a gap of 1–2 millimeters between the brake pads and the outer edge of the brake discs.

Where to Go for the Vehicle License After Transfer?

After the transfer, the vehicle license needs to be returned to the vehicle management office to reprint a new one. Transfer Requirements: To process the vehicle transfer procedures, all previous traffic violations must be settled, the vehicle must pass inspection, and the vehicle must be present. Both the buyer and seller must bring their respective IDs and vehicle documents (such as the vehicle registration certificate and vehicle license) and visit the vehicle management office where the vehicle is registered to inquire and process the transfer. Relevant Laws: "Motor Vehicle Registration Regulations": Article 13: If the motor vehicle owner's residence moves out of the jurisdiction of the vehicle management office, the office shall, within three days of acceptance, annotate the changes on the motor vehicle registration certificate, reclaim the license plate and vehicle license, issue a temporary vehicle license plate valid for 30 days, and hand over the vehicle files to the owner. The owner must apply for vehicle transfer at the vehicle management office of their new residence within the validity period of the temporary license plate.

What Are the Difficulties in Subject 3 of the Driving Test?

The following are the difficulties in Subject 3 of the driving test: 1. Speed and gear mismatch: Subject 3 requires a certain mileage, and gear shifting is one of the mandatory test items. However, during actual driving, students often encounter issues like high gear at low speed or low gear at high speed. Any occurrence of these during the test will result in failure, making speed and gear matching a common challenge for many students. 2. Deviation from straight-line driving: During Subject 2, instructors also teach students how to drive straight. However, in Subject 3, which involves driving on actual roads over longer distances, many students tend to deviate from the straight path without realizing or correcting it, leading to test failure. 3. Parking more than 30cm from the curb: Subject 3 explicitly requires that the parking distance from the curb should not exceed 30cm. However, this distance is difficult for students to gauge accurately, and many end up parking too far from the roadside.

What could be the reason for no response when pressing the accelerator in a 2013 Excelle?

Reasons for no response when pressing the accelerator pedal: 1. Transmission failure: If there is an issue with the transmission, the accelerator may not depress properly, and the engine speed may suddenly increase from 2000 RPM to 4000 RPM. This happens because the power is cut off, causing the engine to suddenly have no load, resulting in fluctuations in RPM. Generally, engine issues are related to problems with the transmission control system. 2. Throttle failure: If the vehicle does not respond or shakes when the accelerator pedal is pressed, it is likely due to a fault in the throttle component, such as a stuck valve plate or a malfunctioning throttle position sensor. 3. Brake override system: Modern vehicles are equipped with a brake override system, which means that if both the brake pedal and accelerator pedal are pressed simultaneously, the brake pedal takes priority, causing the accelerator to become unresponsive. Check if the floor mat is properly secured. If the mat accidentally touches the brake pedal, even slightly, it may trigger a brake signal, activating the brake override system.
