Shifting between D and S gears is not affected by vehicle speed or road conditions, nor does it require braking, and can be done at any time. Here is relevant information: 1. The automatic transmission D/S typically represents the shift between D and S gears. The so-called D gear is the drive gear, an abbreviation of the English word 'Drive'. When the gear lever is moved to this position, the transmission automatically shifts up or down within the engine speed range, with the shift point depending on engine load, the driver's driving style, and vehicle speed. 2. The S gear is the sport mode of the D gear, offering more powerful output. In sport mode, the transmission can shift freely, but shifting is delayed, keeping the engine at high speeds for a longer time, thereby increasing vehicle power. 3. The D gear is the most commonly used driving position. It's important to note that since the automatic transmission determines the gear based on throttle size and vehicle speed, the method of operating the accelerator pedal affects the shifting speed. If the accelerator pedal is pressed quickly at startup, upshifting is delayed, enhancing acceleration capability. Once a certain speed is reached, quickly releasing the accelerator pedal allows the car to upshift immediately, resulting in reduced engine noise and improved comfort.

I've always driven automatic transmission cars, especially on weekends when I often use the S mode for cruising. Shifting from D to S is super easy: while driving, as long as the speed isn't too high, around 30 to 80 km/h, I simply push the gear lever to the S position. There's no need to press the brake, push any buttons, or stop the car—the operation is very smooth. The S mode makes the car more responsive, with higher shift points and stronger power, which is great for climbing hills or overtaking. But remember not to switch at high speeds, like over 100 km/h, to avoid damaging the transmission. I usually use D mode in the city for better fuel efficiency and switch to S mode at highway entrances for quicker acceleration. You might notice the engine sound getting louder, which is normal. Different cars might have slightly different gear lever positions, so it's a good idea to check the dashboard indicator to confirm the shift was successful.

As an automatic transmission driver, I always shift gears with caution. Switching from D to S is straightforward: maintain a steady speed while driving, such as around 40 km/h, and simply move the gear lever to S. No additional steps are needed. S mode provides the car with more power, making it suitable for climbing steep slopes or when you want to accelerate, but avoid keeping it on continuously as it significantly increases fuel consumption. I avoid shifting gears during sharp turns or on bumpy roads, keeping my eyes on the road. For first-time attempts, choosing a straight and flat road is safer. After switching, the throttle response becomes quicker, requiring adaptation to a lighter foot on the pedal. If you feel any jerking, switch back to D as soon as possible. Safety comes first; use S mode only when necessary.

When I drive an automatic transmission car, shifting to S mode is very straightforward. While driving, I simply push the gear lever from D to S position, and it's done instantly. S mode raises the shift points, providing more aggressive acceleration, making it ideal for high-speed overtaking. Just avoid switching at too high speeds, smooth transitions are best.

I'm a newbie who just learned how to shift to S mode. Basic operation: While driving at low speeds, such as 30 km/h, simply push the gear lever to S to complete the shift effortlessly. No button or stopping required. S mode makes the car more responsive and accelerates faster, but it's more suitable to stay in D mode on flat urban roads. Avoid high-speed shifting during initial use; get accustomed to the response first. Check the indicator light for confirmation.
