Why is the steering wheel of the new Sylphy heavy?

New Sylphy's heavy steering wheel may be caused by low tire pressure or steering gear failure. The following are the specific reasons for a heavy steering wheel: Low tire pressure: Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. Toe-in problem: Toe-in can also affect the car's steering. The concept of toe-in is quite complex, but simply put, it helps the steering wheels automatically return to the center, ensuring the car can drive straight stably. Therefore, issues in this aspect can also cause a heavy steering wheel. Steering gear or power steering pump failure: The steering gear and power steering pump also affect the car's steering. Any failure in these two critical components can make steering difficult. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked.

What is the working principle of the brake warning line?

The working principle of the brake pad warning line is that when the brake pads wear down to the preset "limit" after a certain period of use, the natural circuit is "broken" by the wear. This breakage is then detected by the ECU, which triggers the warning light. The brake pad warning alerts the car owner to replace the brake pads in a timely manner. Additional information: Brake warning line: The brake warning line is generally composed of a steel plate, a bonded heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT-4 furnace temperature tracker to ensure the quality of the temperature distribution during coating. The heat insulation layer is made of non-heat-conductive materials to provide thermal insulation. The friction block consists of friction materials and adhesives, which are pressed against the brake disc or drum during braking to generate friction, thereby achieving the purpose of decelerating and stopping the vehicle.

Why is Volvo's first maintenance at 10,000 kilometers?

Different models have different maintenance cycles. Volvo's first maintenance is at 10,000 kilometers because European vehicle maintenance cycles are generally longer, not just 10,000 kilometers, but even up to 20,000 kilometers for the first maintenance. However, this is the ideal maintenance cycle. If the vehicle is frequently driven in harsh conditions, such as urban traffic congestion or short-distance driving, it is recommended to appropriately shorten the maintenance cycle, for example, performing maintenance every 7,500 kilometers would be more appropriate. Below is more information about the first car maintenance: 1. Maintenance content: The first car maintenance is divided into minor maintenance and major maintenance. Minor maintenance includes changing the engine oil and oil filter, while major maintenance includes engine oil, oil filter, air filter, and fuel filter. 2. Maintenance cycle: The first maintenance for a new car is generally limited to within 3 months or 5,000 kilometers, whichever comes first—either time or mileage.

Can Vehicle Purchase Tax Be Paid on Saturdays and Sundays?

In most locations, vehicle purchase tax generally cannot be paid on weekends. It is usually only payable during normal working days from Monday to Friday, though a few places may allow payment on weekends. According to the "Interim Regulations of the People's Republic of China on Vehicle Purchase Tax," the tax rate is 10%. Typically, the taxable amount is calculated based on the vehicle's purchase invoice price (or the minimum taxable price determined by the State Taxation Administration), excluding value-added tax, and then taxed at a 10% rate. Passenger vehicles with an engine displacement of 1.6 liters or below are eligible for a reduced tax rate of 5%, whether they are domestically produced or imported. Passenger vehicles eligible for the tax reduction policy are those primarily designed and technically intended for transporting passengers and their personal belongings or temporary items, with no more than nine seats including the driver's seat. New energy vehicles that meet the criteria specified in the "Announcement on Exempting New Energy Vehicles from Vehicle Purchase Tax" issued by the Ministry of Finance, State Taxation Administration, and Ministry of Industry and Information Technology are exempt from vehicle purchase tax.

How to Tell Which National Emission Standard a Car Meets?

Methods to check a car's national emission standard: 1. Look directly at the front windshield, where the vehicle's environmental protection label is usually clearly marked; 2. Visit the official website for motor vehicle exhaust pollution supervision (Motor Vehicle Environmental Protection Network) to query the information; 3. Check the documents provided by the dealer at the time of purchase, typically starting from the vehicle conformity page or the first page of the vehicle certificate; 4. Bring the vehicle registration form or a copy to the local vehicle management office for inquiry; 5. Make a rough estimation based on the year the car was registered. For example, China VI (National 6) standard refers to the sixth stage of national pollutant emission standards. Compared to China V, China VI imposes stricter control on pollutant emission limits. Under conditions excluding driving cycles and test influences, carbon monoxide emissions from gasoline vehicles are reduced by 50%, total hydrocarbon and non-methane hydrocarbon emission limits are lowered by 50%, and nitrogen oxide emission limits are tightened by 42%.
