How to Operate Deceleration and Downshifting?
3 Answers
In emergency situations, the goal is to stop the vehicle in the shortest distance and fastest time possible. Simply press both the clutch and brake pedals to the floor simultaneously. When decelerating at speeds above 30km/h, use the brake to slow down without pressing the clutch. Determine whether downshifting is necessary based on the current speed and gear.
Having driven a taxi for over twenty years, the operation of slowing down and downshifting with a manual transmission is ingrained in my bones. When I see a red light ahead or need to make a turn, I tap the brake pedal in advance to gradually reduce the speed. At the same time, my left foot immediately depresses the clutch pedal all the way, and my right hand shifts the gear lever into neutral. If the speed drops to around 20 km/h, it's appropriate to shift directly into second gear. If the car body feels slightly dragged, it means the gear is correctly engaged. The key is to gently press the accelerator pedal while releasing the clutch, ensuring the engine speed matches the vehicle speed, so the car won't jerk. On long downhill slopes, it's even more important to utilize engine braking by shifting into a lower gear, which is much safer than relying solely on the brakes. With hundreds of gear shifts every day, I can operate it even with my eyes closed.
I remember my driving instructor emphasized the importance of step-by-step deceleration and downshifting: first apply the brakes to slow down, then when the speed drops to around 30 km/h, press the clutch all the way down and shift to third gear. At this point, you must not rush to release the clutch; wait until the vehicle speed and engine RPM match. The instructor always said to learn to judge by listening to the engine sound—when it sounds sluggish, it's time to downshift. Once, I failed to downshift in time before a turn, and the car shook violently, nearly stalling. The instructor directly criticized me, saying this could damage the transmission. Now when driving, I start preparing to downshift 100 meters in advance, moving my right foot between the brake and accelerator while controlling the clutch depth with my left foot. The entire process needs to be smooth to avoid discomfort for passengers.
