Method to turn on the external air circulation: Locate the button with a car symbol in the air conditioning control area. The button with an arrow pointing from outside the car into the car is the one for turning on the external air circulation. Press this button to activate the external air circulation. Some cars do not have an external air circulation button, only an internal air circulation button. Usually, when the light on the internal air circulation button is on, it means the internal air circulation is active. Pressing it again to turn off the light switches to the external air circulation mode. The external air circulation is suitable for use when it is inconvenient to open windows for ventilation, such as during high-speed driving. The external air circulation can replenish fresh air and also help defog the windshield on rainy days.

First digit: Behavior classification code, indicating the category of the violation under the Road Traffic Law; Second digit: Demerit point classification code, indicating the classification of demerit points for the traffic violation; Third, fourth, and fifth digits: Sequential code, indicating the sequence number of the violation within the same behavior category. For example: 13035—"1" indicates a motor vehicle behavior, the second digit "3" indicates a deduction of 3 points, and the following "035" indicates the fifth item under the third clause in the 3-point deduction category. Behavior classification code violation descriptions: Codes starting with "1" indicate motor vehicle traffic, e.g., 1003; Codes starting with "2" indicate non-motor vehicle traffic, e.g., 2002; Codes starting with "3" indicate pedestrian or passenger traffic, e.g., 3030; Codes starting with "4" indicate highway traffic, e.g., 4002; Codes starting with "5" indicate other regulations, e.g., 5005; Codes starting with "7" indicate implementation rules of provinces, autonomous regions, or municipalities, e.g., 7008; Codes starting with "8" indicate local regulations of cities (prefectures, autonomous prefectures, or leagues), e.g., 8606.

What is the purpose of placing a magnet on a car's exhaust pipe?

Placing a magnet on a car's exhaust pipe serves the following purposes: 1. It can help the fuel burn more completely; 2. It can improve the car's power output and reduce fuel consumption; 3. It also provides good protection for the car's engine and enhances its power. When a car's engine is running, oil backflow occurs, generating many iron particles. These iron particles can travel along the oil circuit into the engine, and over time, they can affect the engine's efficiency, leading to increased fuel consumption. By placing a magnet on the exhaust pipe, these iron particles can be effectively adsorbed, preventing them from entering the engine. This protects the car's engine, and protecting the engine is equivalent to improving the car's power.

How Long Does It Take to Apply Car Window Tinting?

Car window tinting typically takes 3 to 4 hours under normal standards, and can be completed faster in about 2 to 3 hours. If there is old film that needs to be removed, an additional hour is required. Ways to save time during the tinting process: 1. Make an appointment in advance: Call the shop to schedule an appointment, set a time, and arrive on time to avoid waiting in line. 2. Increase manpower: Inform the shop and request additional workers. This can save some time, but the reduction is limited because certain necessary tinting procedures cannot be fully expedited by manpower. Typically, you can save around 2.5 hours.

What does 'Oil Pressure Abnormal, Please Turn Off Engine' mean?

Prompting oil pressure abnormality and engine shutdown indicates a check valve issue in the oil filter. If the oil filter is ruled out, there's a check valve beneath the oil filter that needs replacement. Here's a partial introduction about oil pressure: 1. Working Principle: The oil pressure regulator is essentially an overflow valve controlled by a diaphragm. The diaphragm divides the regulator into an upper spring chamber and a lower fuel chamber. It controls the opening of the overflow valve to maintain pressure balance between the upper and lower chambers. 2. Inspection Methods: Maintenance of the oil pressure regulator includes checking the oil pressure of the fuel supply system, as well as inspecting sealing performance and pressure retention capability. To ensure the fuel supply system provides sufficient fuel under various engine conditions, the actual fuel pressure supplied by the system isn't a fixed value under different operating conditions.
