What are the speed requirements for gear shifting?

[DeKaylee]

When the speed is between 10-20 km/h, shift to 2nd gear; when the speed is between 20-30 km/h, shift to 3rd gear; and when the speed is between 30-40 km/h, shift to 4th gear. After selecting the appropriate gear, perform the corresponding shifting operations. When upshifting, the action should be quick and smooth, and avoid looking down at the gear lever. More details are as follows: Introduction 1: Before upshifting, check the left and right rearview mirrors to ensure road safety. First, release the accelerator with your right foot, then press the clutch with your left foot, and shift to the appropriate gear. Gradually release the clutch while gently pressing the accelerator to increase speed. Introduction 2: When downshifting, also check the left and right rearview mirrors to ensure road safety. Reduce the speed to the upper limit of the target gear before shifting, for example, when downshifting from 4th to 3rd gear, release the accelerator at 40 km/h and shift to 3rd gear when the speed drops to 30 km/h. Introduction 3: During driving, always ensure the gear matches the speed. A mismatch can prevent the car from operating normally and compromise driving safety.
