Can a vehicle pass the annual inspection with traffic violations?

Vehicles with traffic violations cannot pass the annual inspection. New regulations on vehicle annual inspection time: For new vehicles, inspections are required every two years for the first six years, and then annually thereafter. The inspection month corresponds to the vehicle's registration month. Additionally, if the scheduled time is inconvenient, the inspection can be conducted up to three months in advance (e.g., if the inspection month is June, it can be done in April, May, or June). Early inspection does not affect the next inspection date. Considering most people's habits, congestion often occurs at the end of the month, so it is recommended to prepare early at the beginning of the month. Documents required for vehicle annual inspection: Vehicle license, compulsory traffic accident liability insurance policy (copy), inspector's ID card, triangular warning sign, and fire extinguisher. (Traffic violations must be resolved, and vehicle modifications are not allowed). Document explanation: The compulsory traffic accident liability insurance policy consists of the original and a copy.

What does it mean when a vehicle has been intruded?

Vehicle intrusion refers to the situation where the vehicle's anti-theft system was triggered, indicating that the vehicle was either impacted or had its doors opened without authorization. Hardware failure related to the anti-theft system: If there is a hardware failure in components related to the anti-theft system, such as the electronic anti-theft control unit, anti-theft system wiring harness, or alarm horn, the dashboard will display a warning indicating that the anti-theft system requires repair. This warning typically appears during vehicle startup. False alarm: If the SCS security system triggers a false alarm, the warning message will usually disappear immediately after restarting the vehicle. In such cases, the alert can be ignored, or the SCS security software can be refreshed. Refreshing the security software is free during the warranty period at authorized 4S dealerships. Even after the warranty expires, it is often possible to negotiate for a free refresh.

Is it okay to only replace the front tires with winter tires?

Winter tires should not be replaced only on the front wheels. Correct practice: All four tires should be replaced with winter tires of the same specification, brand, structure, and tread pattern. Consequences of replacing only two tires: If only two winter tires are installed, the following situations may occur: Installing winter tires only on the front wheels will result in insufficient grip on the rear wheels, making the vehicle prone to oversteering or brake-induced skidding when driving on winter roads. Installing winter tires only on the rear wheels will lead to insufficient grip on the front wheels, causing steering issues when driving on winter roads. Therefore, it is recommended to replace all four winter tires at the same time, ensuring that tires on the same axle are of the same specification, brand, structure, and tread pattern.

What is the engine model of the Soueast DX7?

The engine model of the Soueast DX7 is the 4A91-turbo engine, with a maximum power of 145KW, maximum horsepower of 197, and maximum torque of 285Nm. The engine of the Soueast DX7 is produced by Shenyang Aerospace Mitsubishi and is a domestically manufactured engine. For daily maintenance of the Soueast DX7 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard being no lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, performance degradation can cause various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate out, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

What does EFI vehicle mean?

EFI vehicle refers to a vehicle equipped with an electronic control fuel injection system, which is the abbreviation for 'electronic control gasoline injection engine'. Advantages of EFI vehicles: The electronic control fuel injection system uses micro integrated circuits to control the fuel injection quantity based on various operating conditions of the vehicle and engine, promoting complete combustion of fuel in the engine, thereby significantly reducing exhaust pollution. Generally speaking, EFI vehicles have performance advantages such as higher power, fuel efficiency, lower noise, and higher one-time ignition rate compared to carburetor vehicles. Difference between EFI and carburetor engines: EFI engines are significantly different from carburetor engines, and there are notable differences in operating methods as well. When starting an EFI engine (including cold starts), it is generally unnecessary to press the accelerator.

Is U-turn allowed at traffic light intersections?

Generally speaking, on the left-turn lane at a traffic light intersection, U-turns are allowed if there is no sign prohibiting U-turns. U-turn rules at traffic lights: At intersections with U-turn traffic lights or traffic signs indicating U-turn lanes on the roadway, U-turns are permitted when safety is confirmed. At intersections without U-turn lights but with left-turn lights, U-turns are allowed. Drivers can make U-turns using the left-turn lane at the central median or when approaching the intersection, provided it does not affect normal traffic flow. Yellow grid areas: Although parking is prohibited in yellow grid areas, if the traffic light ahead is red, vehicles behind should reasonably avoid stopping in this area. The U-turn operation can be completed at the central guardrail. Crosswalk areas: U-turns are not allowed on pedestrian crosswalks. Drivers can make a U-turn after crossing the crosswalk when the light is green, but must never make a U-turn directly on the crosswalk.
