What do the gear letters on an automatic transmission car represent?

[DiHaven]

Automatic transmission gear letters represent the following: 1. P stands for Park, used when the car is parked and not in use. In this position, the wheels are mechanically locked to prevent rolling. 2. R stands for Reverse, used when backing up. 3. N stands for Neutral, used for temporary stops (such as at a red light). To prevent the vehicle from rolling on a slope, the brake must be applied. 4. D stands for Drive, also known as the driving gear, used when moving forward. 5. L stands for Low gear, used when going downhill or on long descents. This limits the car to the lowest gear, allowing the engine to assist in braking, reducing the need for prolonged brake use and preventing brake overheating. 6. S stands for Sport mode. When engaged, gears can be freely switched, but the shift timing is delayed to keep the engine at higher RPMs for increased power. This mode significantly increases fuel consumption.
