Is it necessary to maintain the car at a 4S shop?

It is necessary. Car 4S shops are more professional in focusing on brand models and have higher efficiency in maintenance. When encountering some relatively complex vehicle faults, 4S shops also have some high-end instruments that can solve the problems well. Benefits of maintaining the car at a 4S shop: 1. Professional division of talents: Technicians are only allowed to perform maintenance operations, while senior technicians are qualified to maintain and repair vehicles, and each car's maintenance or repair work is fully responsible by an engineer. 2. Genuine parts supply: The original maintenance parts of the car have a formal and unified supply source, which ensures both quality and unified prices. 3. Strict maintenance operation procedures: The maintenance operation procedures are quite strict, specifying how to maintain the car after driving a certain number of kilometers, which parts to replace, and the charging standards for each process are clearly defined.

What to Do When Stopped by Traffic Police Without a Driver's License

First, explain the reason to the traffic police. If you have your ID card, you can present it, as the ID card can be used to verify your driver's license information. If you don't have any identification documents, the traffic police will impound your vehicle, impose a fine of 200 yuan, and deduct 1 point from your license. You will need to bring your driver's license to the traffic police station and receive the corresponding penalty before you can retrieve your car. Uses of a Driver's License: 1. Proof of Authorization: Driving a motor vehicle requires certain driving skills. Without these skills, driving recklessly could lead to accidents. Generally, people without a license are not allowed to drive on the road. For those who have mastered safe driving techniques, the document that permits them to drive on the road is the 'driver's license.' 2. Purchasing Train Tickets: When buying train tickets, if you forget or lose your ID card, you can present your driver's license instead to purchase tickets. 3. Hospital Registration: When registering at a hospital, if you don't have your ID card, you can present your driver's license at the counter to register, serving the same purpose as an ID card. 4. Hotel Check-In: When traveling or on business trips and needing to stay at a hotel, if you forget your ID card, you can use your driver's license as a substitute for identification.

What to Pay Attention to After Getting Your Driver's License?

After obtaining your driver's license, pay attention to the following points: 1. Display the probationary sign: Newly licensed drivers have a probationary period of 12 months. During this period, a uniform probationary sign should be displayed on the rear of the vehicle you are driving. 2. Avoid accumulating 12 penalty points during the probationary period: As a probationary driver in the first year, you must not accumulate 12 penalty points. If you do, your license will be revoked. After revocation, you must reapply for learning, take the test again, and obtain a new driver's license. 3. Highway driving requires accompaniment: If you need to drive on highways during the probationary period, there must be a driver with more than 3 years of driving experience accompanying you in the front passenger seat. 4. No need to renew after the probationary period: After the first year's probationary period ends, there is no need to renew the license; you can continue using it. 5. Renewal after 6 years: When your driver's license reaches 6 years, you must undergo an annual review and renewal. (According to the expiration date indicated at the bottom of the original license, complete the annual review and renewal at the local vehicle management office or district offices within 90 days in advance.) 6. Transferring the license to another province: If an out-of-town student wishes to transfer their driver's license back to their home province, they must wait until the 1-year probationary period is over before they can complete the transfer procedures at the local vehicle management office. 7. Additional driving permissions: If you are applying for additional driving permissions, you must complete the annual review and renewal within the validity period indicated at the bottom of the original license.

How Long Can Car Wax Last?

Car wax generally lasts for 3-4 months, but this duration depends on the parking conditions and weather environment. If the car is frequently parked outdoors, exposure to sun and rain is unavoidable, especially in southern regions (where rainwater has high acidity). Over time, this will reduce the lifespan of the protective wax, potentially causing it to lose effectiveness in 2-3 months. Below are some precautions for car waxing: 1. Avoid waxing a new car immediately: Some people wax their new cars right after purchase, which is not advisable. New cars already have a layer of protective wax on their paint. Waxing too early may remove this original wax, leading to unnecessary waste. Generally, there is no need to rush into waxing a new car within the first five months. 2. Control the frequency of waxing: For vehicles parked outdoors, exposed to wind and rain, it is best to wax every 2-3 months. Of course, this is not a strict rule. When the car body feels rough to the touch, it’s time to wax again.

Below is some relevant information about car radiators: 1. Concept: The radiator is part of the car's cooling system. The radiator in the engine's water cooling system consists of three parts: the inlet chamber, outlet chamber, main plate, and radiator core. 2. Material: There are two main types of car radiators: aluminum and copper. The former is used in general passenger vehicles, while the latter is used in large commercial vehicles. The materials and manufacturing technology of car radiators have developed rapidly. Aluminum radiators, with their obvious advantages in material lightweighting, are gradually replacing copper radiators in the field of cars and light vehicles. Meanwhile, copper radiator manufacturing technology and processes have made significant progress, and copper brazed radiators have obvious advantages in engine radiators for buses, construction machinery, and heavy trucks.
