The reasons for the air conditioning not cooling in new energy vehicles include: lack of refrigerant. Below are the relevant details: Lack of refrigerant: The most common reason for reduced cooling capacity is the natural depletion of refrigerant. The vehicle's air conditioning system consists of numerous metal pipes, and there are tiny gaps between the connections of these pipes. Therefore, strictly speaking, the refrigerant ("Freon") in the air conditioning system does leak, though the leakage is usually minimal. Diagnosis: The refrigerant level in the air conditioning system can be determined by checking the pressure in the high and low-pressure pipes when the air conditioning is in cooling mode. The high and low-pressure inspection pipes are located in the engine compartment and can be checked using a specialized pressure gauge. When the air conditioning system is operating, the pressure in the high-pressure pipe should be around 12.5 bar, and the pressure in the low-pressure pipe should be between 1.5-2.5 bar.

What documents are required to obtain the inspection exemption label?

According to regulations, motor vehicles that meet the 6-year inspection exemption criteria are exempt from the on-site inspection (i.e., vehicle inspection) process. However, it is still necessary to apply for the annual inspection compliance label (i.e., the label affixed to the front windshield, which has now been digitized nationwide) every two years. In other words, the exemption only eliminates the vehicle inspection step, but the annual inspection label must still be applied for biennially. The following documents must be fully prepared: 1. "Motor Vehicle Inspection Label Application Form" (applicable to vehicles exempt from inspection within 6 years, provided at the service window); 2. Original and photocopy of the vehicle owner's identity proof; 3. Original and photocopy of the vehicle's registration certificate; 4. Original copy of the compulsory traffic accident liability insurance certificate (retained by the traffic management department) (i.e., the original duplicate of the compulsory insurance); 5. Original and photocopy of the vehicle and vessel tax payment or tax exemption certificate.

How many times can points be deducted from a driver's license in a year?

Points can be deducted from a driver's license once a year, and once these points are cleared, a new 12 points will be available. If a driver's license is deducted 12 points, the driver must participate in traffic regulations training organized by the traffic management department within 15 days after the license is temporarily suspended. After completing the training, the vehicle management office must conduct a test on road traffic safety laws, regulations, and related knowledge within 20 days. Below are the risks of point deduction substitution: 1. Inability to protect one's rights: In case of disputes, the driver cannot protect their rights. 2. Negative impact on employment and other aspects: If all points are deducted due to substitution, the driver must retake the exam. Additionally, accumulating too many traffic violation records may severely impact future employment. 3. Severe penalties if discovered: If point trading or substitution is confirmed, the public security department will confiscate illegal gains, re-penalize the traffic violations, and impose heavier penalties on those involved in buying or selling points.

How to Identify Genuine and High-Quality Engine Oil?

Here are the methods to identify genuine and high-quality engine oil: 1. Check the packaging of the engine oil. Genuine engine oil packaging is very detailed and exquisite, with no blurred logos or unclear patterns. The material of the oil cap is fine, smooth, and has a good texture. If the appearance of the oil is blurry and the material is rough, it is likely to be fake engine oil. 2. Examine the seal of the engine oil. The seal is made of tin foil with the brand logo on it, and the sealing effect is good. The seal is neat and uniform, ensuring no leakage. If the seal is not tight, it is likely to be fake engine oil, indicating that it has been opened. 3. Observe the color. Genuine engine oil has a bright, crystal-clear color, and it flows out slowly when poured, with no other impurities or suspended particles in the oil. Fake engine oil, on the other hand, lacks brightness and may appear cloudy.

What should be noted when driving a motor vehicle following the preceding vehicle to make a right turn?

When driving a motor vehicle following the preceding vehicle to make a right turn, the following should be noted: 1. The preceding vehicle: The preceding vehicle may stop to yield to pedestrians or non-motorized vehicles at the intersection; 2. Crosswalk: Pedestrians may suddenly enter the crosswalk; 3. Blind spots: The right side is the non-motorized vehicle lane, and there may be non-motorized vehicles moving straight within the blind spots. More relevant information is as follows: 1. Turn signal: Before changing lanes for a right turn, the turn signal should be activated in advance. This mainly serves as a warning to vehicles behind, as well as electric vehicles, bicycles, and pedestrians. 2. Observe straight-moving vehicles on the left: Before making a right turn, observe the straight-moving vehicles on the left. Checking related accident cases reveals that most accidents occur when drivers neglect to observe straight-moving vehicles while making a right turn, leading to collisions.
