Audi Q5 requires the following steps after battery disconnection: 1. After power loss, the one-touch window function will be disabled. Reactivate the automatic window lift mechanism for electric windows; 2. Post-disconnection, the vehicle's steering angle sensor memory will be lost, triggering ESC and other warning lights on the instrument cluster. The ESP warning light will turn off after driving a few meters upon reconnection. If it persists, recalibrate the steering angle sensor. 3. After power interruption, check all control unit fault memories and delete any low-voltage related fault codes; 4. The vehicle clock will reset after disconnection. Adjust the time to normal via the infotainment system control panel.

What to Do If Driving License and Vehicle License Are Lost?

Need to apply for a replacement. Both the vehicle license and driving license can be replaced at the vehicle management office or the public security traffic management department. You can also apply for a replacement through the mobile app "Traffic Management 12123". The differences between a driving license and a vehicle license are as follows: 1. Driving License: The driving license records the personal information of the driver. You can obtain a driving license by enrolling in a driving school, learning car driving knowledge, and passing the relevant exams. The driving license is proof that the driver is allowed to operate the motor vehicle, and the information on the driving license must match the individual. 2. Vehicle License: The vehicle license records the information of the vehicle. After purchasing a motor vehicle, paying the vehicle purchase tax, and purchasing compulsory vehicle insurance, and filling out the relevant documents, you can obtain the vehicle license. The vehicle license is the "identity proof" of the motor vehicle. The type of vehicle recorded on the vehicle license must match the type of vehicle permitted on the driver's driving license.

How many points will be deducted for overloading a private car with one extra person?

Overloading a private car with one extra person will result in a deduction of 2 points, while overloading a passenger vehicle with one extra person will result in a deduction of 6 points. Article 49 of the Road Traffic Safety Law of the People's Republic of China stipulates: Motor vehicles shall not carry more passengers than the prescribed number, and passenger vehicles shall not carry goods in violation of regulations. The following are the hazards of vehicle overloading: 1. Increased risk of rollover: The more passengers overloaded, the more the vehicle's center of gravity shifts, especially when turning, making the vehicle more prone to rollover. 2. Reduced braking performance: Inertia is related to the mass of an object. When braking, the vehicle relies on resistance to stop. The more overloaded the vehicle, the greater its inertia, making it harder to stop than usual. 3. Tire blowout: Overloading causes the vehicle's tires to operate under excessive load, increasing tire pressure and temperature, which can easily lead to a blowout. 4. Worsened accident consequences: Under normal circumstances, every member in the vehicle has corresponding safety belts, seats, and other equipment. However, with overloading, not everyone has these, making unavoidable situations that could have been prevented in normal conditions.

What does it mean when the 12123 document status is locked?

12123 document status being locked may indicate that there are unresolved traffic violations on the driver's license; there is a record of drunk driving that has not been cleared; there is a record of being penalized with a full 12 points that has not been cleared; or the driver's license is in a state of cancellation, revocation, or suspension. It could also mean that the driver has just obtained the license and is temporarily not allowed to transfer the registration, etc. Below is an introduction to the driver's license: 1. A driver's license is a "permit": Driving a motor vehicle requires certain driving skills. Without these skills, driving a motor vehicle recklessly could lead to traffic accidents. Drivers without a license are not allowed to drive on the road. However, for those who have mastered safe driving skills, the document that allows them to drive vehicles on the road is the "driver's license." This shows that a driver's license is a "permit." 2. Definition of a driver's license: Internationally, a driver's license is defined as: "A document issued by the competent authority permitting the holder to drive a motor vehicle." In China, a driver's license is defined as: "A legal certificate issued by the administrative department to individuals who have legally learned to drive a motor vehicle, have mastered traffic regulations and driving skills after training, and have passed the examination, permitting them to drive a certain type of motor vehicle."
