Why Can't I Schedule the Subject 4 Test After Completing Subject 3?

Subject 4 cannot be scheduled after completing Subject 3 because the Subject 3 results have not yet been uploaded to the vehicle management system. You can only schedule Subject 4 after your Subject 3 results show as passed. Below are the specific details about Subject 4: 1. Concept: Subject 4 is an additional safety and common sense test following the Subject 3 road test. Officially, there is no such term as "Subject 4." 2. Test Content: The exam consists of 50 questions, presented in formats such as case studies, images, and animations. The total score is 100, with a passing score of 90. The main content of Subject 4 includes safe and civilized driving requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge.

What Causes a Car to Lose Power When Accelerating with the AC On?

When a car loses power while accelerating with the AC on, it is primarily because the air conditioning system places a significant load on the engine. This issue is especially noticeable during hot summer months when fuel vaporization increases, leading to reduced fuel pressure within the fuel system. Additionally, a clogged fuel filter can result in insufficient fuel supply. Below are some key points regarding engine maintenance: 1. Use the appropriate lubricating oil: For gasoline engines, select SD to SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB to CD grade diesel engine oil according to mechanical load requirements, ensuring the standard meets or exceeds the manufacturer's specifications. 2. Regularly change the oil and filter: To prevent malfunctions, replace the oil periodically based on usage conditions and maintain an optimal oil level (generally up to the upper mark on the dipstick). As oil passes through the fine pores of the filter, solid particles and viscous residues accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or activate the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and worsening internal contamination.

How to Judge a 360-Degree Surround View System?

360-degree surround view assists in reversing by clearly displaying the surroundings of the vehicle on the screen. The large screen shows the rear view with trajectory lines and is complemented by the gradually changing sound of the parking sensors, helping drivers reverse with ease. Below is an introduction to the surround view system: 1. Definition: The 360-degree surround view system is a parking assistance system that integrates real-time images from around the vehicle, providing a seamless, ultra-wide-angle view on the car display screen. It helps drivers understand blind spots around the vehicle, enabling more intuitive and safer parking. 2. Image Protection: Some car owners prefer using tap water instead of antifreeze in summer, which is highly inadvisable. As the weather cools in autumn, failing to replace it with automotive-specific antifreeze can severely impact the cooling system's performance if temperatures drop suddenly. Therefore, if tap water is used, it must be replaced immediately.

What does 5w40 mean on engine oil?

The "5W-40" on engine oil, the "W" stands for "winter", meaning it is for winter use. The number 5 before the "W" represents the viscosity under low-temperature conditions. Here is a related introduction about the selection of engine oil grades: 1. German cars: Start with 0W40/5W40, but some 30-grade oils are also suitable for German cars. Small-displacement German cars can use 30-grade oils that meet the viscosity requirements when new. 2. Domestic, American, Korean, and French cars: Generally, use 0W30/5W30 within 60,000 kilometers, and switch to 0W40/5W40 after 100,000 kilometers. These four types of car engines have relatively consistent characteristics. The grade can be selected based on the displacement. Small-displacement cars (below 1.8L) can use 0W30 grade for a long time, while large-displacement cars (above 2.0L) can switch to 0W40 grade earlier.

Do I still need to go for vehicle inspection after applying for the exemption mark?

No need to go for vehicle inspection. For motor vehicles exempt from on-site inspection, applying for the exemption mark means the annual vehicle inspection has been completed, and no separate inspection procedures are required. Simply affix the annual inspection sticker on the vehicle for normal use without any impact. Below is an introduction to the time frame for motor vehicles exempt from on-site inspection and the required documents. Time frame for motor vehicles exempt from on-site inspection: The exemption period for motor vehicles is during the second and fourth years of vehicle use. After this period, on-site inspection is required. If the inspection is not completed on time, the motor vehicle cannot be used normally. If the vehicle fails to complete inspection for three consecutive inspection cycles, it will be forcibly scrapped. Documents required for motor vehicle inspection: Whether for on-site or non-on-site inspection, the following documents must be carried: the vehicle's driving license, the current year's compulsory traffic insurance policy, the ID card or a copy of the vehicle owner, along with handling any outstanding traffic violations or unresolved traffic accidents involving the motor vehicle.
