Mercedes-Benz C200 electric fan running continuously is caused by reasons such as excessive water temperature or fan malfunction. The specific explanations are as follows: Excessive water temperature: Because the water temperature in the radiator decreases slowly, the water temperature has not yet dropped immediately after the engine is turned off. At this time, the cooling fan will continue to operate for a period before stopping. The fan runs at high speed to force heat dissipation until the water temperature drops below 85 degrees Celsius, at which point the fan stops. The solution is to simply wait for the temperature to drop. Fan malfunction: If the car has completely cooled down and the fan is still running continuously, it indicates a malfunction in either the cooling fan assembly or the cooling fan circuit. The solution is to promptly inspect the assembly and circuit.

Should I go to a 4S shop or a repair shop for scratches on my new car?

Both options are acceptable. Here is the relevant information: 1. Commercial insurance: If the owner has purchased commercial insurance, which includes scratch insurance, it can be utilized at this time. Simply go to a 4S shop for repainting. 2. Extent of the scratch: The severity of the vehicle scratch should be considered, such as the size and depth of the scratch and whether panel beating is required. Generally, if the area is small and does not require panel beating, the car can continue to be used. After accumulating several months or years of scratches, a unified paint repair can be done, which is economical and hassle-free. During the warranty period of a new car, it is best not to make unauthorized modifications or additions, including self-maintenance. However, repairs like repainting, especially for minor issues, usually do not affect the warranty.

What kind of traffic violation results in a 9-point deduction at once?

Having 9 points deducted from a driver's license at once is considered a compound violation. Here are the relevant details: 1. Regulations: According to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' penalties and point deductions for motor vehicle drivers' road traffic violations are executed simultaneously. If a motor vehicle driver commits two or more violations at once, the points should be calculated separately and accumulated. The 'Regulations on the Application and Use of Motor Vehicle Driving Licenses' is an authoritative administrative decree issued by the Ministry of Public Security of the People's Republic of China, guiding the application and use of motor vehicle driving licenses. 2. Speed limits: Driving a motor vehicle on roads other than highways or urban expressways at speeds exceeding 50% of the prescribed limit, or illegally parking or occupying emergency lanes or shoulders on highways or urban expressways, results in a 9-point deduction.

Are New Energy Vehicle Chargers Waterproof?

New energy vehicle chargers are waterproof, but when charging in the rain, it is necessary to strictly follow the usage and operation instructions. Here are the relevant details: 1. Waterproof materials: Generally, waterproof materials are applied at the bottom of new energy vehicle charging facilities, making the lower part of the charging pile (20-30 cm) resistant to submersion. Insulation detection is also in place to ensure charging safety. 2. Charging standards: After the charging gun is inserted into the vehicle's charging port, the CMS (Charging Management System) first confirms that the charging environment is suitable and safe. Since charging piles operate at high voltage, it is essential to ensure the safety of the vehicle during charging. If any issues arise, the charging gun will not initiate charging, fundamentally avoiding electric leakage and ensuring personal safety during the charging process.

How many kilometers can you drive in one hour?

It depends on the actual speed. Here are the relevant details: 1. Maximum speed: The highest speed is 180KM/h, meaning under ideal conditions, you can drive up to 180 kilometers in one hour; for a 2.4L displacement vehicle, the maximum can reach 200KM/h. 2. Article 78: Expressways should indicate the speed limit for each lane, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. For roads with 2 lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; for roads with 3 or more lanes in the same direction, the minimum speed for the far-left lane is 110 kilometers per hour, and the middle lane's minimum speed is 90 kilometers per hour.

Is the Vehicle License Required to Be Kept in the Car?

Vehicle License must be kept in the car. Here are the relevant details: 1. Motor Vehicle License: It is the legal document that permits a motor vehicle to drive on roads within China. The license consists of three parts: the license holder, the main page, and the supplementary page. The front of the main page contains the endorsed core, while the back features a photo of the vehicle, all sealed in a plastic cover. The supplementary page also contains the endorsed core. 2. Article 17 stipulates: "A vehicle must pass the inspection by the vehicle management authority and obtain a license plate and a Vehicle License before it is allowed to drive." Therefore, possessing a Motor Vehicle License is one of the prerequisites for a vehicle to be driven on the road. Driving without carrying the Vehicle License is a violation, whether it is due to not having obtained the license or simply forgetting to bring it.

Will driving in S gear have any impact?

It will increase fuel consumption but has no impact on the vehicle. Here are the relevant details: 1. S Gear: This is the sport mode, which essentially increases the engine's power output by raising the shift RPM and increasing fuel injection. The sport mode in cars is generally controlled by the transmission computer, meaning the shift programming is different. 2. Benefits: The car's transmission will shift freely, but the shift timing is delayed, forcing the engine to maintain higher RPMs for a longer period. Although using S gear can reduce some safety hazards during overtaking and better utilize the engine's braking effect when going downhill, thereby improving safety.
