You should not continue driving when the radiator overheats. Find a safe place to pull over, but do not turn off the engine immediately. Let the engine idle to continue dissipating heat, and open the hood to speed up the cooling process. Do not open the radiator cap to avoid being scalded by hot liquid that may spray out. When the engine is overheated, do not pour water on the engine block or cylinder head, as this can cause the block to crack. After allowing some time for cooling, turn off the engine once the water temperature drops to a suitable level. Reasons for radiator overheating include: 1. Radiator leakage or insufficient coolant, preventing the engine heat from dissipating and the temperature from lowering in time; 2. Deteriorated coolant with reduced boiling point, affecting its cooling performance.

What does brake-hold mean in a car?

brake-hold refers to ABH (Auto-Brake-Hold), the automatic parking system. When the function is activated, the vehicle can be stopped by pressing the brake pedal during temporary stops. To resume driving, simply press the accelerator pedal to release the braking force. This allows the driver to avoid prolonged braking when the vehicle is stationary and prevents unnecessary rolling when the automatic electronic parking brake is engaged. Additional Information: 1. Meaning of the Automatic Parking System: The automatic parking system (Auto-Brake-Hold) is a technology that enables the automatic application of the parking brake while the vehicle is in operation. This technology allows the driver to avoid prolonged braking when the vehicle is stationary and prevents unnecessary rolling when the automatic electronic parking brake is engaged. The function of the automatic parking system is to prevent the vehicle from rolling backward, making it particularly useful on slopes and during frequent stops and starts. 2. Function of the Automatic Parking System: The automatic parking system, together with the electronic parking brake (EPB: Electrical-Park-Brake, technical name: electromechanical parking brake), forms an intelligent braking control system. This system integrates temporary braking during driving and long-term braking after parking, and the parking brake is controlled electronically.

What is the probability of being caught running a red light when following a large vehicle?

The probability of being caught running a red light when following a large vehicle is 100%. Never take chances, as electronic traffic police are machines, not humans. As long as you cross the line when the red light is on, you will be captured. Criteria for determining running a red light: The electronic eye captures three photos as evidence for running a red light: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be considered running a red light. Otherwise, the act of running a red light is not established. Even if you are mistakenly captured, you can apply for administrative reconsideration with the traffic management department. Penalty points for running a red light: According to Article 2, Section 1, Clause 2 of the 'Scoring Standards for Road Traffic Safety Violations,' driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. Article 3, Section 1, Clause 8 states that driving a motor vehicle in violation of prohibition signs or stop line instructions will result in a deduction of 3 points.

How Long Can a Vehicle Annual Inspection Be Overdue?

There is no grace period for overdue vehicle inspections. Whether it's one month or just one day past the deadline, it is considered a violation of the law. If your vehicle's annual inspection has expired, you should promptly visit the vehicle management office or an automotive testing station to complete the inspection. Failing to conduct the annual vehicle inspection as required by the deadline is an illegal act, and traffic management authorities have the right to impose administrative penalties, typically a warning or a fine of up to 200 yuan. After paying the fine, the vehicle owner should proceed with the annual inspection as required. Relevant information about vehicle annual inspections is as follows: 1. Introduction: Vehicle annual inspection (Vehicles-inspection), also known as motor vehicle inspection. The inspection items and scope vary depending on the nature of the vehicle's use. 2. Inspection Items: According to the definition in RB/T218-2017 "Requirements for Qualification and Assessment of Inspection and Testing Institutions - Motor Vehicle Inspection Institutions," motor vehicle inspections include three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive vehicle performance inspection.

What is 4WD in cars?

4WD stands for "Four-Wheel Drive", which means all four wheels have driving force. 4WD includes three forms: full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. In the early years, four-wheel drive was mainly used for rugged off-road vehicles, but now it is also used in urban SUVs, and many mid-to-high-end sedans and luxury sports cars also adopt four-wheel drive. The following is an introduction to full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive: 1. Full-time four-wheel drive : Cars equipped with a full-time four-wheel drive system are always in four-wheel drive mode, and this system is commonly found in some luxury SUV models. 2. Part-time four-wheel drive: This four-wheel drive system can switch between four-wheel drive and two-wheel drive via a switch inside the car. Most off-road vehicles with part-time four-wheel drive have a low-range four-wheel drive function. When switched to low-range four-wheel drive, the torque on the wheels is further amplified, helping the vehicle to escape difficult situations. 3. On-demand four-wheel drive: This four-wheel drive system is generally used in some urban SUV models or some front-engine cars. Cars equipped with an on-demand four-wheel drive system usually drive in front-wheel drive mode, and power is distributed to the rear wheels only when the front wheels slip or when full acceleration is needed. On-demand four-wheel drive has lower costs and lower fuel consumption, making it suitable for use in some urban SUVs and sedans.

What to Do When the Car Windshield Fogs Up?

Here are the methods to defog the windshield before driving: 1. Use a Special Defogging Agent: There are specialized defogging agents available in the automotive decoration and beauty market. Spray this type of defogging agent onto the inner surface of the car window and wipe it clean. While removing dirt from the glass, it also forms a thin, transparent protective film on the glass, effectively preventing the formation of fog caused by condensation. One application can prevent fogging for about 10 days. 2. Turn on the Air Conditioning While Blowing Hot Air: According to the car manual, the method to defog is to adjust the air conditioning vents to the windshield setting, turn on the air conditioning switch, and let the compressor work to dehumidify. However, if the temperature control knob is set to the cold air setting, the passengers inside the car will feel very cold. Therefore, you can place the temperature knob in the warm air position to achieve both defogging and heating purposes. 3. Open the Window Slightly: If you notice that the fog inside the car is not too heavy, you can open a small gap in the side windows. This allows the air inside and outside the car to circulate, reducing the temperature difference and causing the fog to gradually disappear. The principle of this method is the same as turning on the air conditioning cold air, but it does not increase fuel consumption.

What to Do If You Haven't Enrolled Within 15 Days After Losing All 12 Points on Your Driver's License?

If you haven't enrolled within 15 days after losing all 12 points on your driver's license, your license will enter a suspended status, and you cannot drive a motor vehicle. It will not be revoked, but you must contact the traffic management department to arrange for learning as soon as possible. More details are as follows: 1. Penalty: If a motor vehicle driver accumulates 12 penalty points within a scoring cycle, the traffic management department of the public security authority will confiscate their driver's license. The driver must report to the traffic management department of the public security authority at the place where the license was issued or where the violation occurred within 15 days to participate in a seven-day study session on road traffic safety laws, regulations, and related knowledge. 2. Related Information: Losing 12 points only requires passing a theoretical test. Once you pass, you can regain your driver's license (with 12 points reinstated). Only if you accumulate 12 points or more twice within one scoring cycle, or if your total points reach 24 or more, will you need to take a road test. However, this does not require a lengthy period of time.
