M gear refers to the manual mode, which allows an automatic transmission vehicle to be switched to manual mode for driving. Automatic transmission gear positions include P, R, N, S, D, M, and L gears. P stands for Parking gear, R stands for Reverse gear, N stands for Neutral gear, S stands for Sport gear, D stands for Drive gear, and L stands for Low gear. Here are the detailed introductions: 1. P gear: Mainly used after the vehicle has come to a stop. Engaging the P gear can prevent the vehicle from rolling or moving. 2. R gear: Primarily used when reversing, but it can only be engaged after the vehicle has stopped. For some models with a lock button, the button must be pressed to switch gears. 3. N gear: Mainly used for temporary stops, such as at traffic lights or when pulling over briefly. It is prohibited to use this gear when going downhill. 4. S gear: The S gear can be switched to and from other gears at any time. It allows the vehicle to accelerate quickly in a short period, making it suitable for overtaking. 5. D gear: This is the most commonly used gear during driving. After engaging the D gear, there is no need to switch gears; the speed can be controlled directly by pressing the accelerator pedal. 6. L gear: This gear is suitable for use when going uphill or downhill. Using it uphill can reduce brake usage, while using it downhill provides continuous power for climbing. 7. M gear: It allows the automatic transmission vehicle to be switched to manual driving mode. The '+' and '-' on the M gear represent upshifting and downshifting, respectively.

I've been driving an automatic transmission car for several years, mainly using the D (Drive) mode for effortless convenience. However, there's also an M (Manual) mode in the car, which allows us to shift gears manually like a manual transmission vehicle. The operation is quite simple: while driving, shift from D to M mode, then manually upshift or downshift using the paddle shifters on the steering wheel or the +/- buttons on the gear lever. For example, when going downhill, shifting to a lower gear utilizes engine braking to prevent brake overheating and protect the braking system. I also use M mode to maintain lower gears on snowy or muddy roads for better traction and safety. Compared to the automatic shifting in D mode, M mode offers more control and driving pleasure, but beginners should practice in open areas first. Other automatic transmission positions like P (Park), R (Reverse), and N (Neutral) are used in specific scenarios and shouldn't be confused. Overall, M mode is a standout feature of automatic transmissions, especially suitable for driving environments requiring precise control, and is worth trying out.

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%.

How many liters of transmission oil does the Magotan B8 require?

The transmission oil for the Magotan typically needs to be replaced every 40,000 kilometers or two years. Approximately 7 liters are required for a gravity oil change, while around 12 liters are needed for a circulation oil change. Function of the transmission: As the gears operate at high speeds during driving, friction generates heat. Transmission oil is necessary to lubricate and reduce temperature, ensuring the vehicle operates normally. It also helps minimize oil loss under demanding operating conditions. There are two methods for changing transmission oil: One is the traditional gravity method, which involves draining the oil by loosening the transmission's drain plug, similar to changing engine oil, and then refilling with new oil. The other method uses a circulation machine to change automatic transmission oil, primarily utilizing the machine's pressure to dynamically replace the oil in the torque converter's lubrication and cooling lines.

Is Resetting the Transmission Useful?

Resetting the transmission is useful. The original design of automatic transmission reset was intended as an emergency troubleshooting method to restore the transmission control unit (TCU) program when it hangs or crashes. Before resetting the transmission, it is necessary to check the transmission control unit to ensure there are no fault codes. If fault codes are present, the transmission memory function cannot be reset. The core function of an automatic transmission is to enable automatic gear shifting. Automatic gear shifting means that while the car is in motion, the driver operates the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on the engine load and the vehicle's operating conditions. Automatic transmissions, as opposed to manual transmissions, are devices that can automatically shift gears based on the vehicle's speed and engine RPM. Currently, there are four common types of automatic transmissions in vehicles: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch transmission (DCT).

Can I Cancel the Subject 2 Test Reservation on Saturdays and Sundays?

You cannot cancel the Subject 2 test reservation on Saturdays and Sundays. The driving test center is closed on weekends and statutory holidays. As a government department, it operates on fixed working hours, which are from 8:30 AM to 12:00 PM and from 2:00 PM to 5:30 PM, Monday to Friday. If the scheduled test plan has not yet closed, you can cancel the reservation through the [Traffic Management 12123] platform. However, if the test plan has closed or the test has been successfully scheduled, you must go to the vehicle management office to cancel the reservation, and you must do so at least one day before the test. Some larger and more formal driving schools can also handle the cancellation of test reservations, but generally, you can only cancel the reservation at the vehicle management office on normal working days. Usually, you can cancel the reservation online before receiving the confirmation SMS for the successful reservation. If an applicant cannot attend the test at the scheduled time for any reason, they must apply to cancel the reservation one day in advance. If the applicant fails to attend the test at the scheduled time without cancellation, the test will be marked as a failure.
