What is the reason when the car doesn't move in D gear and pressing the accelerator doesn't work?

The reason why the car doesn't move in D gear and pressing the accelerator doesn't work is that the hill start assist is automatically activated. Hill Start Assist: Hill Start Assist, also known as Hill-start-Assist-Control. To prevent difficulty in starting on a slope, the hill start assist control temporarily (for a maximum of about 3 seconds) applies braking to all four wheels to prevent the vehicle from rolling backward. When starting on a steep or slippery slope, if the driver switches from the brake pedal to the accelerator pedal, the vehicle may roll backward, making it difficult to start. Configuration Reason: When hill start assist control is not equipped, the driver must quickly and accurately switch from the brake pedal to the accelerator pedal. However, when hill start assist control is equipped, because it can prevent the vehicle from rolling backward, the driver can easily start the car and operate the pedals with ease.
