Generally speaking, because the automatic transmission has a locking mechanism, an automatic car cannot shift gears without pressing the brake, which effectively prevents accidents caused by driver errors. Automatic transmission cars have gears such as R, P, D, N, L, and S. The specific usage is as follows: 1. R gear: Used for reversing, also known as the reverse gear. Note that the car must come to a complete stop before shifting into R gear. 2. P gear: Used for parking, meaning the engine stops working. Many people refer to this as the parking gear. 3. D gear: Primarily used for driving the car forward, known as the drive gear, and is the basic gear for automatic cars. 4. N gear: Similar to the neutral gear in manual transmissions, with no difference in principle. It can be used when stopping at a red light. 5. L gear: A low gear, typically used for uphill driving or overtaking. 6. S gear: The sport mode, allowing free switching between all gears.

What is the brand of the Xingyue L transmission?

The manufacturer of the Xingyue L transmission is Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The Xingyue L transmission uses an 8-speed automatic transmission. The automatic transmission utilizes a 4-speed automatic. Automatic transmission: During driving, the transmission will automatically adjust to the most appropriate gear ratio based on the throttle position and vehicle speed. For the Xingyue L transmission in daily use, the following points should be noted: Do not delay changing the transmission oil for extended periods. Prolonged failure to change the transmission oil can lead to damage to internal components such as bearings and the housing; Avoid prolonged coasting in neutral. While driving manual transmission models, many 'experienced drivers' may coast in neutral, but for automatic transmission models, coasting in neutral can cause the automatic transmission to overheat, and shifting back into D gear may produce a certain impact; Never shift into D/R gear before the vehicle has come to a complete stop. Many drivers, to demonstrate their 'smooth' operation, may shift directly into reverse gear before the vehicle has fully stopped, which can cause significant damage to the transmission gears and, over time, lead to gear grinding and other faults; Do not frequently use D gear to climb steep slopes. When facing steep slopes, automatic transmission vehicles often overheat due to high load or shift up too early, resulting in insufficient climbing power. In such cases, manual mode can be used to limit low gears or sport mode to protect the transmission; Do not tow over long distances. When an automatic transmission vehicle breaks down, a flatbed tow truck should be used to move the vehicle onto the tow platform while it is in N gear, rather than using a tow rope or directly towing the vehicle.

What are the new regulations for vehicle annual inspection in Ningbo in 2021?

New regulations are introduced as follows: 1. Expand the scope of private car exemption from inspection and optimize the inspection cycle: On the basis of exempting non-operational mini and micro passenger vehicles with 6 seats or fewer from inspection within 6 years, non-operational mini and micro passenger vehicles with 7 to 9 seats within 6 years are now included in the exemption range. For non-operational mini and micro passenger vehicles over 6 years but less than 10 years old, the inspection frequency is adjusted from once a year to once every two years. 2. Electronic inspection labels: Electronic inspection certificates have the same effect as paper certificates. Vehicles that have obtained electronic inspection certificates no longer need to display paper labels, and traffic authorities will not penalize vehicles for not displaying (or affixing) inspection labels. Electronic inspection certificates can be downloaded and saved on mobile phones for offline use when needed. 3. Extension of inspection due to COVID-19: If a vehicle is required to undergo a safety technical inspection during the epidemic prevention and control period, the inspection will be uniformly extended based on the epidemic situation. (For transport vehicles, the annual inspection cycle is automatically extended until 45 days after the end of the epidemic.)
