What are the symbols for the internal and external air circulation in the Magotan?

An upward arrow coming from outside the car indicates the external air circulation symbol; an arrow inside the car indicates the internal air circulation symbol. Below are detailed explanations of the internal and external air circulation in cars: 1. External Air Circulation: External air circulation refers to drawing air from outside the vehicle, directing it through the air conditioning system for heating or cooling, and then blowing it out through the vents. Essentially, external air circulation replenishes fresh air to improve the air quality inside the car. It should be used for defrosting in winter or defogging in summer because the air drawn from outside is richer in oxygen and drier, making it more effective for defrosting or defogging. 2. Internal Air Circulation: Internal air circulation draws air from inside the vehicle, creating a cycle of airflow within the car. Its main function is to promptly and effectively prevent external dust and harmful gases from entering the car. It helps warm up the car faster in winter and cool it down quicker when the air conditioning is on in summer. It can also be used during smoggy days. Internal air circulation maintains the internal air cycle, helping to better preserve the temperature inside the car.

What Causes DMI Engine Vibration?

DMI engine vibration can be caused by severe engine carbon deposits, ignition system failure, or unstable oil pressure, as detailed below. Severe Engine Carbon Deposits: The most common cause of car vibration is a dirty throttle valve or excessive carbon buildup in the fuel injectors. When there is too much carbon inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start the engine. Ignition System Failure: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or spark plugs can also lead to such issues. Unstable Oil Pressure: If you have already cleaned the engine carbon deposits, cleaned the throttle valve, and replaced the spark plugs but still notice body vibration at idle, you can inspect whether the fuel supply pressure and the intake pressure sensor are functioning properly. Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can also cause body vibration.

Should You Look Left or Right First When Crossing the Road?

Whether to look left or right first when crossing the road depends on the traffic direction regulations of the road. In mainland China, vehicles drive on the right side of the road, so you should look left first, then right. In Hong Kong, vehicles drive on the left, so you should look right first, then left. Additional information: 1. According to the "Road Traffic Safety Law of the People's Republic of China," pedestrians should walk on sidewalks; where there are no sidewalks, they should walk on the side of the road. When crossing at intersections with traffic signals, pedestrians should follow the traffic signals. When crossing at intersections without traffic signals or crosswalks, or when crossing roads without pedestrian facilities, pedestrians should ensure safety before proceeding. 2. Citizens must use crosswalks when crossing the road and are prohibited from jaywalking on vehicle lanes. At intersections with pedestrian crossing signals, pedestrians should follow the "red light means stop, green light means go" rule. At intersections without pedestrian crossing signals, pedestrians should still use crosswalks to cross the road. When crossing the road, pay attention to oncoming vehicles: first look left, and when reaching the middle of the crosswalk (road centerline), check for vehicles coming from the right, then cross quickly after confirming there is no danger.

Does Installing a Rearview Camera Count as Vehicle Modification?

Installing a rearview camera does not count as vehicle modification. Altering or replacing configurations and changing technical specifications constitute modifications, whereas adding a rearview camera is considered installing an auxiliary device. A rearview camera is also known as a parking assist system, reverse visual system, or onboard monitoring system. Its English name is vehicle-backup-camera. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. Additional information: 1. According to Article 21 of the "Road Traffic Safety Law of the People's Republic of China": Before driving a motor vehicle on the road, the driver must carefully inspect the vehicle's safety and technical performance; it is prohibited to drive a motor vehicle with incomplete safety facilities or components that do not meet technical standards, posing safety hazards. 2. According to Article 90 of the "Road Traffic Safety Law of the People's Republic of China": If a motor vehicle driver violates the road traffic safety laws and regulations regarding road traffic rules, they shall be given a warning or fined between 20 and 200 yuan. In cases otherwise stipulated by this law, penalties shall be imposed according to the relevant provisions.

Is it still necessary to display the auto insurance sticker now?

In most regions, it is no longer required to display the auto insurance sticker. Insurance companies now provide paper policies and compulsory traffic insurance labels, which have been replaced by electronic policies and electronic compulsory traffic insurance labels. Additional information regarding auto insurance stickers is as follows: 1. Digitalization: Before the cancellation of the compulsory traffic insurance sticker, the environmental protection label for vehicles had already been abolished, and the annual inspection label has also been digitized. Therefore, it is no longer mandatory for vehicle owners to display stickers on their vehicles. The abolition of stickers and the move towards digitalization is considered a major trend. This not only reduces costs, saves resources, and eliminates the hassle of tearing off/attaching stickers for vehicle owners but also does not obstruct the driver's view, ensuring driving safety. Additionally, it can improve operational efficiency to some extent, making it a win-win situation. 2. Note: Cities that have explicitly abolished the compulsory traffic insurance sticker include Beijing, Shanghai, Sichuan, Yichang City, Shanxi, Guangdong, Henan, Hubei, Shandong, etc. Some areas may still require the display of stickers as there is no official confirmation yet. If you are unsure, it is best to consult the local traffic police department.

What to Do If Your Car Is Towed and You Can't Find It?

If your car is towed and you cannot find it, you can resolve the issue by negotiating with the other party through the traffic police. Once the matter is settled, you can retrieve your car from the vehicle management office with the completed documentation. If mediation fails, you can proceed with legal action. As long as the accident compensation is settled, you can retrieve your vehicle. The following are places where illegal parking may result in towing: 1. Roadside illegal parking: Parking illegally on main roads, three-way intersections, T-junctions, crossroads, or pedestrian crossings, which severely obstructs the passage of other vehicles and pedestrians, is highly likely to result in towing. 2. Life rescue channels: For example, parking illegally in front of fire stations, hospital entrances, or emergency room entrances, which affects the safety of others' lives and property, may lead to towing. 3. 'Blocking the entrance' parking: Parking in front of parking lot entrances, shopping mall entrances, office building entrances, school entrances, etc., known as 'blocking the entrance' parking, may result in towing.
