What are the functions of the various gears in a manual transmission car?

[DeCamilla]

Manual transmission gear functions are introduced as follows: 1. First gear is the starting gear, used when the car begins moving from a complete stop. Another meaning of the starting gear is that it's only used for starting - once the car starts moving, you need to shift to second gear. 2. Second gear is the driving gear, used when the car is moving at very low speeds. This means as long as the car is moving slowly without stopping, you can use this gear (not for high-speed driving). Some vehicles with higher idle speeds can even start moving in second or third gear by pressing the accelerator, though this operation is not recommended. 3. Third gear is the acceleration gear. Starting from this gear, you can use the accelerator to increase speed and bring the car to a certain velocity. 4. Fourth gear is the medium-high speed driving gear. On most urban roads (excluding elevated roads), this is generally the highest gear needed. Depending on the vehicle, it's typically used when maintaining speeds around 60-70 km/h. 5. Fifth gear is the high-speed gear, used only on elevated roads or highways, generally at speeds of 80 km/h or above. 6. R gear is the reverse gear, used when backing up the car.
