What Does a Malfunction in the Vehicle Pedestrian Protection System Mean?

Does adding too much car antifreeze have any impact?

Adding too much car antifreeze does have an impact. The effects are: during the use of the car, it will undergo thermal expansion and overflow stains from the pressure relief valve. The function of car antifreeze is: to prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or cover when the car is parked in cold winter. The method of replacing antifreeze is: 1. Unscrew the radiator cap to drain the antifreeze; 2. Let the engine idle and inject clean water until the radiator discharges clean water; 3. After the clean water has drained, close the water valve; 4. Add new antifreeze so that the liquid level is between the max and min water level marks; 5. Cover the cap and let the engine idle for two or three minutes. The precautions for using car antifreeze are: 1. Try to use the same brand of antifreeze; 2. When adding, confirm that the product is within its validity period; 3. Avoid diluting it with water; 4. If a large amount of particle precipitation appears, it indicates that the antifreeze has deteriorated and can no longer be used.

What is the function of the engine radiator?

The engine radiator is a key component in the automobile cooling system, serving to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator where the heat is dissipated, and then returns to the water jacket to circulate, thereby regulating the temperature. Dissipating excess and unnecessary heat: The cooling system of the automobile radiator can disperse excess and unnecessary heat from the engine, ensuring that the engine operates at normal temperatures under various speeds or driving conditions. Preventing cooling system pipe bursts: The automobile radiator is a heat exchanger for water-cooled engines, maintaining the engine's normal operating temperature through air convection cooling. If the engine coolant in the radiator boils and vaporizes due to high temperature, causing the pressure to exceed the set value, the radiator cap releases the pressure by overflowing, reducing the coolant volume and preventing the cooling system pipes from bursting.

What to Do When Car Key Is Hard to Insert?

The solution for a car key that is hard to insert is: crush pencil lead and apply it to the keyhole. The steps are: 1. Use a knife to scrape the pencil lead into powder; 2. Put the powdered pencil lead into a plastic tube and blow it into the keyhole; 3. Repeat the above steps until the car key can be inserted and removed smoothly. The working principle of a car key is: it emits a weak radio wave from the owner, which is received by the car antenna. After the electronic controller identifies the signal code, the system's actuator performs the action of unlocking or locking. The functions of a car key include: 1. Remote locking and unlocking; 2. Long-press the lock button after turning off the engine to close the windows; 3. Press the horn-shaped button to locate the car.

Can a temporary ID card be used for the driving test Subject 1?

Bringing an ID card is sufficient for the test, as electronic IDs cannot be used. If you don't have an ID card, you can apply for a temporary one, which holds the same validity as a regular ID card. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," you can take Subject 1 twice on the same day. If you fail the first attempt, you can retake it for free. If you fail the second time, the Subject 1 test will be terminated, and you can only reschedule after ten days. The Subject 1 test consists of 100 questions, including single-choice and true/false questions, each worth 1 point, totaling 100 points. If you answer 11 questions incorrectly, the system will automatically submit the test and end the session. Subject 1 is a computer-based test with a duration of 45 minutes. Subject 1 test content: Regulations on driving licenses and motor vehicle management; 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 dress appropriately (no slippers), avoid bringing electronic devices or bags into the test center, and bring their ID cards. Queue up to enter the waiting hall, observe the instructions and procedures on the screen, and store personal items in lockers before entering the test room. At the identity verification counter, you will be assigned a seat. Once seated, begin the test, ensuring the camera is aligned correctly and adhering to test discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After completion, queue to collect and sign the score report—unsigned reports are invalid. There is no limit to the number of Subject 1 test reschedules. Each subject can be taken once, with one retake if failed. If you skip the retake or fail it, the test ends, and you must reschedule. For Subject 2 and Subject 3, only five attempts are allowed, with rescheduling permitted after ten days. If you fail the Subject 3 safe driving knowledge test, the previously passed road driving skills test scores remain valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers road traffic laws, regulations, and related knowledge; Subject 2 evaluates field driving skills; Subject 3 includes two components: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, often unofficially called "Subject 4," though this term is not used in official documents (e.g., Ministry of Public Security Order No. 123). The test duration is 45 minutes.
