Which gear should be used when driving a Civic downhill?

[LeKendra]

Civic uses R gear when driving downhill. In addition, many SUV models are equipped with HDC (Hill Descent Control), which can be activated on steep slopes to achieve automatic deceleration without the need to press the brake pedal. The vehicle will pass through at a very slow speed, and the driver only needs to steer. Using D gear for downhill driving: In fact, there is no problem using D gear for downhill driving, as the automatic transmission shifts gears entirely through the vehicle's computer. If the accelerator pedal is continuously pressed, the speed will increase, and the computer will interpret this as a need to accelerate, thus continuously upshifting. Decelerating by pressing the brake: If the brake is pressed to decelerate, the transmission will continuously downshift. However, the manual-automatic mode limits the vehicle's upshifting and downshifting. For example, shifting from D gear to L gear, which is a low-speed mode, means that even if the accelerator pedal is continuously pressed, the vehicle speed will not increase sharply.
