If the MAX button is inside the car, it generally refers to the air conditioning's maximum cooling function; if located on the engine oil dipstick, it indicates the maximum fluid level - do not exceed the MAX mark when adding engine oil. Typically, only the air conditioning system features a MAX button inside vehicles. When pressed, the AC will enter maximum cooling mode to rapidly lower the cabin temperature. The car air conditioner is a crucial comfort feature. Its cooling principle is quite simple: during operation, the AC button must be pressed to engage the compressor clutch, allowing the engine to drive the compressor which continuously compresses refrigerant and circulates it to the evaporator.

Can I take a makeup exam on the same day if I'm late for the Subject 1 test?

No, you cannot. For the Subject 1 test, you can take it twice on the same day. If you fail the first attempt, you must remain seated and proceed directly to the second attempt. Leaving your seat and exiting the examination room means forfeiting the makeup exam opportunity. Below are detailed explanations: 1. Explanation 1: If you fail the Subject 1 test, you can retake it once after one month, with the first makeup exam being free. 2. Explanation 2: If you fail again, you need to reschedule, and the timing depends on the driving school's arrangements. 3. Explanation 3: The vehicle management office must accept applications from those who meet the requirements for a driver's license and arrange the test according to the scheduled date. The test sequence follows Subject 1, Subject 2, and Subject 3 in order. You can only take the next subject's test after passing the previous one.

Is entering the license plate number sufficient for checking vehicle violations?

Entering the license plate number alone is insufficient for checking violations, as violation records constitute personal information. To prevent arbitrary access, in addition to the license plate number, the engine number or vehicle identification number (VIN) must also be entered. Both the engine number and VIN can be found on the vehicle's registration certificate. Additional relevant information is as follows: 1. After a violation: It is recommended that vehicle owners wait at least three days before checking. Violation photos require manual review by traffic police and subsequent information upload and release. According to relevant regulations, the review of violations captured by electronic monitoring systems must be completed within ten days, and uploaded to the database within three working days for vehicle owners to access. 2. Note: If a violation cannot be found after ten days, the likelihood of a violation is minimal. If the electronic eye has indeed captured a violation, the mobile phone number registered with the vehicle management office will receive a notification. Vehicle owners only need to follow the instructions in the SMS notification to address the matter promptly.

What is the reason for the ESC stability control failure preventing the car from starting?

The solutions for the stability control system failure preventing the car from starting are as follows: 1. Generally, this occurs when the system detects an ESC fault during power-on self-test, thus preventing ignition. The ESC module must be checked and confirmed to be functioning properly before ignition is allowed; 2. The Electronic Stability Control (ESC) is a new active safety system in vehicles, which is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functions. It additionally incorporates a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor during cornering. Through the ECU, it controls the driving and braking forces of all four wheels to ensure lateral stability during vehicle operation; 3. This system consists of three main components: sensors, Electronic Control Unit (ECU), and actuators. The ECU monitors the vehicle's operational status and intervenes to control the engine and braking system. A typical ESC system includes sensors such as four wheel speed sensors, steering wheel angle sensor, lateral acceleration sensor, yaw rate sensor, and brake master cylinder pressure sensor. The actuator components include conventional braking systems (vacuum booster, pipelines, and brakes) and hydraulic modulators. The ECU works in conjunction with the engine management system to intervene and adjust engine power output.
