What does the gear M mean in a car?

[PaigeDella]

The M gear is the manual mode of an automatic transmission car. M stands for Manual, meaning entering the manual shifting mode. In manual mode, by manually pushing the gear lever to M+ or M-, the transmission computer will receive commands to shift up or down, and then the computer will control the transmission to shift accordingly, simulating manual gear shifting. Automatic transmission cars also have other letter gears such as P, R, N, D, S, and L. Below is a detailed introduction: The P gear stands for Parking, the R gear stands for Reverse, the N gear stands for Neutral, the D gear stands for Drive, the S gear stands for Sport, the L gear stands for Low, and the M gear stands for Manual. Different gear combinations output different power. When the car is at different speeds, it needs to "shift gears," i.e., select different gear combinations to output power. Below is an explanation of each gear: P gear: Parking means "stopping." It is the parking gear, used when parking. When you arrive at your destination or need to park for a long time, shift the gear lever into this position. Note: The vehicle must be completely stopped before shifting into P gear. Shifting into P gear before the vehicle is fully stopped can cause mechanical damage to the automatic transmission. When in P gear, the wheels are mechanically locked, preventing the vehicle from moving forward or backward. Therefore, always shift into P gear when parking on a slope. Additionally, during short stops (e.g., at traffic lights), it is best not to shift into P gear to avoid severe damage to the transmission in case of a rear-end collision. R gear: Reverse means "backward" and is used for reversing. To reverse, press the safety button on the gear lever and shift into R gear. However, ensure the vehicle is completely stopped before shifting to avoid severe damage to the transmission. 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 waiting time is long, it is recommended to engage the handbrake, allowing your foot to rest. A common misconception is that shifting into N gear while coasting downhill or at high speeds saves fuel. This is a serious mistake; it not only does not save fuel but can also damage the transmission. D gear: Drive means "driving" and is the forward gear in a car. Shifting into this gear and pressing the accelerator allows the car to move. In this gear, the transmission automatically shifts based on speed and throttle conditions. At traffic lights, you can stay in D gear and press the brake. If the wait is short, this is fine, but prolonged waiting can raise the transmission oil temperature and degrade the oil. S gear: Sport means "sport" and is the sport mode in a car. Shifting into this gear delays the shift timing to provide more power, usually used when overtaking. L gear: Low means "low speed" and is the low-speed forward gear in a car. In this gear, the transmission only operates in low gear (equivalent to manual gear 1) and does not automatically shift to other gears based on speed. This gear is typically used when climbing or descending slopes. In low gear, the driving wheels output more 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 vehicle's movement, eliminating the need for constant braking.
