In winter, there is no need to turn on the AC for heating because the working principle of the car heating system is different from that of cooling. The car heating system uses the heat emitted from the exhaust pipe and radiator to warm the air, which is then blown into the cabin by the fan, without the need to activate the compressor. The AC button in the car is for the cooling function of the air conditioning system. Pressing it activates the compressor, and in some models, an indicator light on the button will illuminate, while others may display a prompt on the central control screen. The car air conditioning system is designed to adjust and control the temperature, humidity, air cleanliness, and airflow inside the vehicle cabin to a comfortable state, providing a pleasant riding environment for passengers.

What to Do When an Exclamation Mark-like Warning Light Appears on the Vehicle Dashboard?

When an exclamation mark appears on the car dashboard, there are five possible scenarios: general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: A triangle with an exclamation mark inside indicates a general performance or component malfunction in the car. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. Transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Abnormal Tire Pressure: A horizontal line under parentheses with an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

Is the Car's Tire Pressure Monitoring Accurate?

Car tire pressure monitoring values are very accurate and operate in real-time, capable of immediately detecting if a tire is leaking. Tire pressure monitoring automatically and continuously checks the air pressure in the tires while driving, alerting the driver to leaks or low pressure to ensure driving safety. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is then transmitted from inside the tire to a central receiver module via a wireless transmitter, where the data for each tire's pressure is displayed. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the differences in rotation speed between the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor air pressure. Introduction to Tire Pressure Monitoring Systems (TPMS): TPMS combines the advantages of both systems mentioned above. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only direct systems, this hybrid system can reduce costs and overcome the indirect system's inability to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.

Which switch controls the front window defogging function in a Mercedes-Benz?

Mercedes-Benz's defogging function is the same as the front windshield defrost function. On the air conditioning control panel below the CD player, there is a fan-shaped button with three curved upward arrows, which is the defogging switch. The button to the right of the fan is for front defrosting; simply turn on the A/C to activate defogging. Since the temperature inside the car is higher than the outside temperature, fog tends to form. More details are as follows: Convection defogging: If the fog inside the car is not heavy, you can slightly open the side windows to create air convection between the inside and outside of the car. This reduces the temperature difference, and the fog will gradually disappear. Cause of fogging: When fog forms on the inner surface of the glass, the outside temperature is lower than the inside temperature. Consequently, the temperature of the front windshield is lower than the inside temperature, causing the water vapor inside the car to condense into small droplets on the glass. This results in a white, foggy appearance on the window.

Does passing during a yellow light count as running a red light?

According to Article 38 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China,' vehicles that have already crossed the stop line when the yellow light is flashing at an intersection may continue to pass. If the yellow light is already on and you continue to force your way through, being caught on camera in such a situation will also count as running a red light. According to the relevant provisions in Article 10 of the 'Regulations on the Handling of Road Traffic Safety Violations,' motor vehicle drivers who violate traffic signal lights at intersections will be penalized with 6 points. Additionally, according to the relevant provisions in Article 90 of the 'Road Traffic Safety Law,' a fine may also be imposed. Criteria for determining running a red light: Electronic cameras will take 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 available will it be considered running a red light. According to Article 11 of the 'Regulations on the Handling of Road Traffic Safety Violations,' if you run through the stop line when the red light is on but manage to stop the vehicle even if you have already crossed the line, it will not be considered running a red light. However, it will be considered stopping beyond the line, and according to traffic laws, it is classified as driving or stopping at an intersection not in accordance with regulations, resulting in a 2-point penalty. How to avoid running a red light while driving: When there are arrow signal lights, follow the arrow lights; otherwise, follow the circular lights; When the red light is on, the front of the vehicle must not cross the stop line; When the yellow light is on, the front of the vehicle must not cross the stop line; When the green light just starts flashing, if you are close and moving fast, you should pass because you might not be able to stop in time and cross the stop line; if you are far away, moving slowly, or the intersection is congested, you should stop; When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line at an intersection.
