P stands for Parking gear, used when parking. The following are the meanings of the letters on an automatic transmission: 1. P gear is the parking gear on an automatic transmission car. When parking, shift the gear to P to prevent the vehicle from rolling backward. 2. R gear is the reverse gear of an automatic transmission car. After shifting into R gear, the car will generate backward traction, which is used for reversing into parking spaces and parallel parking. 3. N gear is the neutral gear of an automatic transmission car. Unlike manual transmission cars, it does not completely disconnect the transmission from the engine, so N gear cannot be used for coasting and should only be used briefly when waiting at traffic lights. 4. D gear is the drive gear of an automatic transmission car. Simply shift into D gear, press the accelerator to speed up, and press the brake to slow down to drive the vehicle. 5. S gear is the sport gear of an automatic transmission car. It allows the car to deliver stronger power and acceleration, suitable for use on highways and in congested traffic. 6. L gear is the low gear of an automatic transmission car, also known as the climbing gear. It reduces the car's speed to ensure the engine delivers strong power, often used on bumpy roads or for long uphill climbs to provide sufficient power. 7. M gear is the manual gear on an automatic transmission car. After switching to M gear, you can perform upshifts and downshifts to match the gear accuracy required during actual use.

The gear for parking is the letter P, which stands for Park. Normally when I park, I first step on the brake to come to a complete stop, then shift into P, and finally pull the handbrake and turn off the engine. I remember one time my friend forgot to shift into P, and the car rolled several steps downhill, almost hitting a tree, which scared us quite a bit. When parking in underground garages at shopping malls, I deliberately turn the steering wheel slightly to the side so that even if the handbrake isn’t fully engaged, the car won’t roll easily. If the car won’t be driven for a long time, it’s best to shift into N after P to give the transmission a rest, though nowadays many cars come with electronic parking brakes, making the auto-hold function much more convenient. In short, P is the standard for parking—never get it wrong.

The parking gear is the one marked with P, and I've been using it this way for ten years of driving. At red lights, you don't actually need to shift into P; just press the brake or use the auto-hold function, or you can shift into N. However, you must shift into P before turning off the engine after parking, as it locks the transmission to prevent the wheels from moving. Once, I saw a car in an underground garage slowly rolling backward because it wasn't in P, and the owner was scrambling in the driver's seat—it was quite amusing. Actually, just remember three steps to avoid this: stop the car and press the brake, shift directly into P, and firmly engage the handbrake. If parking on a slope, it's safer to engage the handbrake first and then shift into P. Different car brands might have slight variations in shifting methods, but the function of P is the same.

The parking gear is denoted by the letter P, which stands for Parking. The process of starting an automatic transmission car is quite simple: press the brake to start the engine, shift from P to D, and you're ready to drive. For parking, it's the reverse: after coming to a complete stop, shift from D back to P before turning off the engine. The step beginners most often forget is engaging the P gear. Once, a relative of mine just got a new car, parked at a mall, and walked away without shifting to P, only to find the car had rolled into a green belt the next day. Nowadays, many new cars are smarter and automatically shift to P when the door is opened, but developing the manual habit is always good. When waiting briefly for someone, there's no need to shift to P; using the electronic parking brake is sufficient and causes less wear on the transmission.
