Here is an introduction to what each letter in PRDSL represents in an automatic transmission: P: P stands for Park. It is similar to the P sign you see in parking lots, used when parking the car. The P gear is mainly used for long-term parking, such as when you arrive at a parking lot or home. In such cases, you should shift to P and then turn off the engine. However, remember not to use this gear for brief stops like waiting at a traffic light. R: R stands for Reverse. This gear is engaged when you need to reverse the car and is located below the P gear. When using it, be sure that the car has come to a complete stop before shifting into reverse. Forcing it into reverse while the car is still moving can damage the transmission gears. N: N stands for Neutral. It works on the same principle as the neutral gear in a manual transmission. This gear is used for brief stops (e.g., waiting at a red light. Note: If the stop lasts less than 2 minutes, you can use this gear, but for stops longer than 2 minutes, it’s better to shift to P as it saves more fuel). D: D stands for Drive. This is the most frequently used gear. As the saying goes, "Drive takes you everywhere." Once the car is in this gear, you can press the accelerator and move forward. S: S stands for Sport. The car feels much more powerful in this gear. For example, with the same throttle input, the D gear might shift to the next gear at 2200 RPM, while the S gear could delay the shift until 2500 RPM or even 3000 RPM. This allows for greater engine power output and improved acceleration performance. L: L stands for Low. Generally, the car can generate more power at low speeds, making this gear useful when climbing hills. It makes hill climbing much easier. This is the same principle as shifting to 1st gear in a manual transmission when going uphill. However, some cars do not have this gear.
