There are impacts. Although convenient, modifying the original car wiring poses safety hazards. Below are relevant introductions about car keys: 1. Precautions: If a car key is lost, the original key data should be cleared promptly. Upon discovering the loss of a car key, it is advisable to visit a 4S store as soon as possible for key matching. The original key data stored in the car's computer should be cleared, and then the spare key should be rematched through online diagnostics. 2. Lost key matching: It is recommended to go back to the original 4S store for matching. Since the password of the car's original remote control is exclusive and specially matched, this also ensures the safety of the consumer's vehicle usage.

What are the symptoms of brake fade?

The most obvious symptom of brake fade is a significant decrease in braking power, making it difficult to stop the vehicle. Here is a detailed introduction to brake fade: 1. Definition: Brake fade refers to the phenomenon where the braking force diminishes due to high temperatures generated by intense friction between the brake disc and brake pads. 2. Causes: After a certain number of braking actions, the temperature of the brake pads in a car's braking system (such as disc brakes or drum brakes) rises. When the optimal operating temperature is reached, the braking performance is at its best. However, if the temperature exceeds the maximum limit, the braking distance increases and the braking effectiveness deteriorates. This phenomenon is known as brake fade. 3. Solutions: When experiencing brake fade, you can downshift to a lower gear to utilize engine braking effectively. If the brake fade is severe, it is best to pull over immediately and wait for the braking system to cool down naturally before continuing to drive.

Are the Tires Replaced at 4S Stores Genuine OEM Tires?

4S stores use genuine OEM tires because all replacement parts at 4S stores must be covered by warranty. Using OEM tires enhances structural and performance guarantees to some extent. This reflects 4S stores' commitment to quality. Advantages of using OEM tires: 1. Vehicle Compatibility: OEM tires (parts) are custom-designed for specific vehicle models, ensuring they maintain the same technical specifications and quality as the original new car parts. This achieves perfect compatibility with your vehicle and preserves its optimal performance. 2. Quality Assurance: Every OEM tire (part) used at 4S stores is quality-certified by the automaker, offering excellent performance and reliable operation. 3. Lifespan and Cost Considerations: For parts replaced at the customer's expense, replaced free of charge, or replaced free of charge due to recall repairs outside the vehicle warranty period (excluding wear-and-tear parts specified in the home vehicle three-guarantee certificate), the quality warranty period is 1 year or 20,000 kilometers, whichever comes first.

How Many Times Can You Take the Driving License Test Subject 1?

There is no limit to the number of times you can take the Subject 1 test. As long as you fail, you can retake it until you pass. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," you can take the Subject 1 test twice on the same day. If you fail the first attempt, you can retake it for free the second time. If you fail the second attempt, the Subject 1 test is terminated, and you can only schedule another test after ten days. Subject 1, also known as the theoretical test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. A score of 90 out of 100 is required to pass the Subject 1 test. The test consists of 100 questions, including single-choice and true/false questions, with each question worth 1 point. If you answer 11 questions incorrectly during the test, the system will automatically submit the test and end it. Subject 1 test content: Driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: Candidates should pay attention to their attire during the test—no slippers are allowed. Electronic devices and bags are not permitted in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen and store personal belongings in a locker before entering the examination room. Upon entering the examination room, the identity verification station will assign a seat. Once seated, begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, you can retake it the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it. Failure to sign will render the test invalid. There is no limit to the number of times you can schedule the Subject 1 test. Each subject test can be taken once, with one retake allowed if you fail. If you do not take the retake or fail the retake, the test is terminated, and the applicant must reschedule. In contrast, Subject 2 and Subject 3 allow only five test attempts. Subject 2 and Subject 3 tests can be scheduled ten days later. If you fail the Subject 3 safe driving knowledge test, the passing score for the road driving skills test remains valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include Subject 4.
