When your car needs to be started again, start the car first, then put your right foot on the brake, put it in gear (from P to D) and release the brake. If the car idles, it won't slip for a short time. At this point, the foot slowly releases the brake, lightly steps on the accelerator, and the vehicle starts climbing.
If it is too late to start climbing and slipping, you must first step on the brake and then pull the hand brake. These are two independent braking systems of the vehicle. Ensure safe parking. After the vehicle stops, just follow the above steps.
When going downhill, the vehicle should also start, and don't turn off the engine and slip away, which is very dangerous.
Before going downhill, start the vehicle, put it into low gear, release the brake and put your foot on the brake to avoid taking measures when the speed is too fast.
