The P gear stands for Parking gear, which is used when the vehicle is parked. It is the most common gear in automatic transmission vehicles, usually located at the frontmost position of the gear shift console, ahead of the R gear. Its principle is to lock the car using an internal device in the transmission. When you reach your destination or need to park for an extended period, shift the gear lever into this position. Note: Always ensure the vehicle is completely stopped before shifting into P gear. Shifting into P gear before the vehicle has fully stopped can cause damage to parts of the automatic transmission. When in P gear, the wheels are mechanically locked, preventing the vehicle from moving forward or backward. Therefore, always engage P gear when parking on a slope. Additionally, during brief stops (e.g., at traffic lights), it's best not to shift into P gear to avoid severe damage to the entire transmission in case of a rear-end collision. Besides, manual transmission vehicles have numbered gears such as 1, 2, 3, 4, and 5, while automatic transmission vehicles have lettered gears like P, N, D, S, M, and L. Introduction to manual transmission numbered gears: First gear is the starting gear, used when the car begins moving from a stop. Another meaning of the starting gear is that it is only used for starting; once the car starts moving, you need to shift to second gear. Second gear is the driving gear, used for low-speed driving. It means the car moves at a very low speed, not for high-speed driving. Third gear is the acceleration gear. Starting from this gear, you can accelerate by pressing the throttle to increase the car's speed to a certain level. Fourth gear is the medium-high-speed driving gear. On most urban roads (excluding elevated roads), this is the highest gear you'll typically use, generally for speeds around 60-70 km/h. Fifth gear is the high-speed gear, used only on elevated roads or highways, usually for speeds of 80 km/h or above. Introduction to automatic transmission lettered gears: N gear: Neutral means "neutral" and is also called the neutral gear. At traffic lights, you can shift into this gear and press the brake. If the wait is long, it's advisable to engage the handbrake, allowing your foot to rest off the brake pedal. A common misconception is that shifting into N gear while coasting downhill or at high speed saves fuel. This is a serious mistake—it not only doesn't save fuel but can also damage the transmission. D gear: Drive means "drive" and is the forward gear in a car. Shift into this gear, press the accelerator, and the car will move. In this gear, the transmission automatically shifts based on speed and throttle input. At traffic lights, you can stay in D gear with the brake pressed. For short waits, this is fine, but prolonged waits can raise transmission oil temperature and degrade the oil. S gear: Sport means "sport" and is the sport mode in a car. In this gear, the transmission delays shifting to provide more power, typically used for overtaking. M gear: Manual means "manual" and switches the car to manual mode, requiring manual gear changes like in a manual transmission. L gear: Low means "low" and is the low-speed forward gear. In this gear, the transmission operates only in low gear (equivalent to first gear in a manual transmission) and does not shift automatically based on speed. This gear is typically used for climbing or descending steep slopes. In low gear, the drive wheels output high torque, providing sufficient power to climb steep slopes. Prolonged braking can overheat the brake pads, reducing braking effectiveness, which is dangerous on long or steep descents. Shifting into L gear uses the engine's low RPM to control the car's movement, eliminating the need for constant braking.
