What is the correct usage of D and S gears?

[DiLila]

Here is the usage of D and S gears: 1. D (Driving) is the forward gear. When driving in this gear, the hydraulic control system shifts gears according to the preset program, operating entirely based on the set logic—simply press the accelerator. 2. S (Sport) is the sports gear. When engaged, the hydraulic system only connects to the first and second gears of the forward gears, and the automatic transmission can only shift automatically between these two gears, unable to engage higher gears. The upshift is delayed, naturally resulting in stronger power. When shifting from D to S gear, there will be a noticeable downshift phenomenon. This forced downshift is to obtain greater output torque, making the car feel more 'powerful'.
