How Early Can a New Vehicle's Annual Inspection Be Conducted?

According to the "Motor Vehicle Registration Regulations" (Order No. 102 of the Ministry of Public Security), the owner of a motor vehicle can apply for an inspection compliance mark at the vehicle management office of the registration location up to three months before the expiration of the motor vehicle's inspection validity period. For example, if the annual inspection deadline for a vehicle is September 2018, the earliest date for inspection would be July 1, 2018. Below are the relevant details: 1. New vehicle inspection schedule: (1) Non-commercial passenger vehicles are exempt from annual inspection for the first 6 years, but a proof must be submitted to the vehicle management office every 2 years. After 6 years, an annual inspection is required. (2) Commercial passenger vehicles require an annual inspection every year. (3) Large commercial vehicles under 10 years old require an annual inspection, while those over 10 years old require a semi-annual inspection. (4) Commercial passenger vehicles and non-commercial passenger vehicles over 15 years old require an annual inspection. 2. Documents required for vehicle inspection: Original vehicle license; Copy of compulsory traffic insurance; Copy of ID card; The vehicle itself. 3. Vehicle inspection items: (1) Check whether the engine, chassis, body, and attached equipment are clean, complete, and effective, whether the paint is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records. (2) Verify whether the vehicle's braking performance, steering control, lights, exhaust, and other safety features meet the technical requirements for safe motor vehicle operation. (3) Check whether the vehicle has been modified, altered, or reconstructed, whether the vehicle license, license plate, and all registered vehicle records match the actual condition of the vehicle, whether there have been any changes, and whether approval and modification procedures have been completed. (4) Check whether the license plate, vehicle license, and enlarged license plate markings on the vehicle are damaged, altered, or illegible, and whether they need replacement. (5) For large vehicles, check whether the unit name or the name of the street, township, or town where the vehicle is registered and the maximum seating capacity in the driver's compartment are spray-painted in Chinese imitation Song font on both sides of the door as required.

What is the fuel consumption of the Roewe RX5?

The comprehensive fuel consumption of the Roewe RX5 is 6.8-6.9L/100km. There are currently 10 models of the Roewe RX5 on sale: the Automatic National Tide Edition, Manual National Tide Edition, Manual National Tide Smart Edition, Jifeng National Tide Smart Edition, Automatic National Tide Premium Edition, Automatic National Tide Ultimate Edition, Automatic National Tide Smart Edition, with a comprehensive fuel consumption of 6.9L/100km. The Automatic 4G Internet Million Edition, Automatic 4G Internet Million Flagship Edition, and Manual 4G Internet Million Edition have a comprehensive fuel consumption of 6.8L/100km. The above figures are the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 7.2-9.9L/100km. When driving, the following 5 tips can help reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Light acceleration, light braking, early braking: While driving, gently press the accelerator to avoid sudden increases in engine RPM and prevent the car from shaking during operation, thereby making the car more fuel-efficient. By anticipating road conditions and applying slow and even acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular vehicle maintenance or inspection: Regular oil changes can reduce carbon deposits (carbon deposits can cause poor ignition, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter if dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per mileage. Close windows while driving. Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption.

What Taxes Should Be Paid When Buying a Car?

Taxes to be paid when buying a car include consumption tax, value-added tax, purchase tax, and vehicle and vessel tax. Here are the specific details: 1. Consumption Tax: The purchase tax frequently mentioned when buying a car is actually an extra-price tax. In reality, automobile manufacturers also need to pay taxes when producing cars, including the consumption tax, which is an intra-price tax. The automobile consumption tax was newly established during the national tax reform in 1994 and was included in the "Interim Regulations of the People's Republic of China on Consumption Tax" implemented on January 1, 1994. For passenger cars, three tax rates are set based on different engine displacements, and this tax is levied on manufacturers. 2. Value-Added Tax (VAT): The current VAT system is based on the "Interim Regulations of the People's Republic of China on Value-Added Tax" (State Council Decree No. 134) issued by the State Council on December 13, 1993. VAT is a turnover tax levied on the value-added amount generated during the circulation of goods (including taxable services). A 17% tax rate applies to the sale of goods, provision of processing, repair, and replacement services, import of goods, and tangible movable property leasing services, which includes automobile transactions. 3. Purchase Tax: On September 22, 2016, the Ministry of Finance issued a notice stating that from January 1, 2017, to December 31, 2017, a 7.5% purchase tax rate would be applied to passenger cars with engine displacements of 1.6 liters or below. Starting from January 1, 2018, the statutory purchase tax rate of 10% was reinstated. The formula for calculating the new car purchase tax is: New car purchase tax = (New car price including tax ÷ 1.17 [VAT rate of 17%]) × purchase tax rate. Here, the 17% VAT must be deducted before multiplying by the purchase tax rate to avoid double taxation. 4. Vehicle and Vessel Tax: The vehicle and vessel tax, also known as the vehicle and vessel usage tax, is a usage behavior tax levied on vehicles traveling on public roads and vessels navigating domestic rivers, lakes, or ports. The tax is calculated based on the type (e.g., motor vehicles, non-motor vehicles, passenger cars, cargo trucks, etc.), tonnage, and prescribed tax rates.

How to Use Car Lights Correctly?

Here are the specific conditions for using car lights: 1. High beam and low beam: High beams should only be used when there are no streetlights and no oncoming vehicles, as they can significantly impair the vision of other drivers and potentially cause traffic accidents. Therefore, high beams should be used with caution. Low beams should be turned on during dusk when lighting is insufficient or at night. In conditions such as rain, snow, or fog, low beams should be used even during the day. 2. Fog lights: Fog lights are designed to make your vehicle visible to others in low-visibility conditions like fog or heavy rain. Therefore, fog lights need to have strong light penetration. Most vehicles use halogen fog lights. 3. Hazard warning lights: Hazard warning lights are used in the highest alert state while driving. They should be turned on during emergencies or when the vehicle needs to stop due to a malfunction. 4. Turn signals: Turn signals are the primary device for indicating a vehicle's dynamic information. They must be activated when turning to alert other vehicles and pedestrians. 5. Brake lights: Brake lights are bright and highly visible, serving to alert following vehicles that you are slowing down or stopping. Proper use of brake lights can help prevent rear-end collisions. 6. Reverse lights: Reverse lights are installed at the rear of the vehicle and are all white. They illuminate the area behind the car to reduce blind spots and alert pedestrians and other vehicles that the car is reversing. 7. Daytime running lights: As the name suggests, daytime running lights are used during the day. Their purpose is not to help the driver see the road but to make others aware that a vehicle is approaching. Therefore, these lights are not for illumination but serve as signal lights. 8. Position lights: Position lights, also known as parking lights, can be turned on in places with insufficient lighting, such as garages, to alert other vehicles.

What does ECM mean in a car?

ECM in a car stands for Engine Control Module, which has the function of continuously monitoring and controlling the normal operation of the engine. In modern engine management systems, the ECM is the core control component. It can provide the engine with the appropriate air-fuel mixture and ignition timing based on different engine operating conditions, ensuring the engine remains in good working condition and achieves optimal performance. The automotive engine control module is an important automotive electronic component. Early ECMs required three printed circuit boards, composed of 12 LSIs and dozens of SSIs. Today, ECMs have evolved to be microcontroller-based, requiring only a single printed circuit board.
