Why does the dash cam not light up after being turned on?

If the dash cam does not light up after being turned on, it may be due to the screen saver function being activated either during startup or by default. Another possible reason is a power connection issue, which requires checking the power supply. By installing a dash cam, drivers can record video and audio during vehicle operation, which typically serves as evidence in traffic accidents, safeguarding the driver's legal rights. The dash cam also records the vehicle's speed, time, and location within the footage, functioning similarly to a black box in an aircraft. When the vehicle is not in use, it can also serve as a parking monitor. However, the video data stored in the dash cam cannot be edited, as any alterations would render it useless in providing assistance during traffic accidents.

Does OFF mean on or off?

In cars, OFF means off, and ON means on. The OFF light on a car mainly refers to ESP-OFF. ESP stands for Electronic Stability Program, which is an active safety device designed to prevent the vehicle from skidding or fishtailing. If the ESP-OFF light on the car's dashboard comes on, it means that the vehicle's electronic stability control system is either turned off or has malfunctioned. More information about the ESP-OFF button is as follows: 1. If you accidentally press the ESP-OFF button on the vehicle, simply press it again briefly to turn the ESP back on. If the ESP-OFF light is on due to a system malfunction, the vehicle should be sent to a 4S shop for repair as soon as possible. 2. There are many reasons why the malfunction light may come on, such as wiring faults, sensor damage, incorrect signals from the electronic control unit, or a weak battery.

How to Deal with Rust Spots on White Cars?

The methods for handling rust spots on white cars are: 1. Use a clay bar. Most rust spots only exist on the surface of the paint. In this case, you can use a clay bar to scrub. The clay bar has a grinding effect and can remove stubborn stains on the car body. For rust spots on white paint, first wet the car body, then use the clay bar (make sure it is softened by soaking). Rub the rust spots evenly back and forth while keeping the car body moist. 2. Use polishing. If the clay bar cannot remove the rust spots on the white paint, polishing can be used to eliminate them. Polishing can also remove minor scratches on the car body, but be mindful of the polishing intensity. 3. Use an iron remover. Purchase and apply a professional iron remover by pouring it onto the rust spots. This will dissolve the rust, after which you can wipe it off with a sponge and rinse with clean water. If the rust is not completely removed in one attempt, repeat the process.

What is the content of the Subject 4 driving license test?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses", the Subject 4 test consists of 50 questions, primarily in the form of case studies, pictures, and animations, with a full score of 100 and a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: the road test and the addition of a safety and civilization knowledge test, commonly referred to as Subject 4. It is not a separate subject but is called Subject 4 because it is conducted after Subject 3. Officially, there is no Subject 4. The safety and civilized driving knowledge test is conducted after Subject 3. There is no limit to the number of times you can take the Subject 4 test. If you fail the first test on the same day, you can retake it on the spot. If you still fail, you need to reschedule the test, and no additional fees are required for retakes. However, it is important to note that the validity period of the driving skill test permit is three years. If the applicant does not complete the test within the validity period, the results of the already passed subjects will be invalidated. Subject 4 test considerations: Test duration: The test lasts 45 minutes, and if you answer 10 points (5 questions) incorrectly during the test, the session will be terminated. Number of questions: Depending on the type of driving license being tested, 50 questions are selected proportionally from the corresponding Subject 4 question bank, with each question worth 2 points. Question types: The test includes single-choice questions (including true/false questions) and multiple-choice questions, with questions presented as animations, pictures, scenario recognition, and text descriptions. Retake considerations: If you fail Subject 4, you only need to retake Subject 4. The driving school will schedule the retake, and there is no limit to the number of retakes. You can retake it continuously until you pass, and no additional fees are required for Subject 4 retakes. Subject 4 test tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just look at the correct answers and memorize them. Refer to regulations, textbooks, or reference books to find out the reasons for the mistakes and understand them. Categorize and summarize the questions. You can refer to the question bank analysis for categorization and find similar questions: Many questions in the bank are similar and can be confusing, so they should be analyzed and summarized. For example, traffic signs for walking, hiking, pedestrian attention, crosswalks, and crosswalk attention have very similar patterns and can be confusing. During study, categorize them to avoid mistakes. Find memory techniques: Many questions in the bank involve numbers, which can be summarized for easier memorization. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge test.

What are the reasons for windshield wipers not spraying water?

The reasons for windshield wipers not spraying water are: 1. The wiper nozzle is clogged or the pipeline is detached. It is recommended to check the spray nozzle; 2. The fuse is blown and needs to be replaced. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high, using a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives the four-bar linkage, which converts continuous rotational motion into left-right oscillating motion.
