How to Operate Gears When Decelerating?

The correct method for gear shifting during deceleration: release the accelerator, gently press the brake, and pay attention to the speed on the dashboard; when the speed reaches 20km/h (30km/h when shifting from 4th to 3rd gear), keep the brake pressed, depress the clutch, and shift gears; after shifting, simultaneously release the clutch and brake. More details are as follows: 1. General deceleration: In most normal driving conditions, the speed in 3rd gear is 20~30km/h. In these situations, you may need to lightly press the brake to decelerate: (1) When the distance to the car ahead decreases, or the speed approaches or even exceeds 30km/h—simply release the accelerator, and if you feel further deceleration is needed, lightly tap the brake. (2) When passing through straight intersections, bus stops, crosswalks, or school zones—maintain a speed close to 30km/h beforehand, and upon reaching the operational area, release the accelerator, press the brake, then release the brake and continue pressing the accelerator to proceed. 2. Decelerating to stop: When stopping at a red light or coming to a final stop, you can do this: first press the brake to decelerate to 20km/h, then depress the clutch, increase brake pressure, and after the car stops, quickly shift to neutral and release the clutch. 3. Emergency braking: In case of sudden situations requiring emergency braking, simultaneously press the clutch and brake, wait for the speed to decrease, shift to the appropriate gear, then release the clutch and brake. For an emergency stop, after stopping, quickly shift to neutral and release the clutch.
When I slow down while driving, I always gently press the brake first to gradually reduce the speed. Once I feel the speed has decreased, I press the clutch and shift to a lower gear, such as from 5th gear down to 3rd or 2nd gear, so that the engine RPM matches the speed, helping to relieve braking pressure. On steep slopes or before traffic lights, I'm used to operating this way, which saves brake pads and protects the engine from stalling. Automatic transmission cars usually handle this on their own, but if it's a manual-automatic transmission, I switch to manual mode to downshift and enhance control. Remember not to skip gears when downshifting—going directly from high to low can cause the car to jerk and damage the drivetrain. Regular practice is essential to handle various road conditions smoothly.
From my driving experience, the key to deceleration is to first apply steady braking to reduce speed, then coordinate with the clutch to shift to a lower gear. Avoid slamming on the brakes or dropping gears too quickly, as this can easily cause the engine to stall or the brake pads to overheat. Especially in urban traffic congestion, I anticipate deceleration points in advance, such as starting the operation 100 meters before a traffic signal, sequentially downshifting from higher gears to ensure a smoother stop. Automatic transmission vehicles generally handle this automatically, but on long downhill slopes, I manually downshift to prevent loss of speed control and protect mechanical components, extending their lifespan. In summary, synchronizing gear shifts during deceleration enhances safety and reduces the likelihood of accidents.
During deceleration, I focus on gear coordination: promptly downshifting after braking to utilize engine braking, thereby reducing the burden on the brakes. This is particularly useful in corners or high-speed exits, allowing for more effortless speed control and preventing skidding. I've developed a habit in daily driving, such as ensuring RPM matching before downshifting for a smooth transition that doesn't harm the vehicle.
