The methods to prevent the car from slipping on steep slopes are as follows: 1. Proper use of the handbrake: When using the automatic start, just tighten the handbrake and slowly lift the clutch to the engagement point. At this time, immediately stabilize the clutch and put down the handbrake, so that the car will not slip. 2. Correct gear shifting: When you feel that the car has spare capacity to drive in a higher gear, you should shift to a higher gear in time. That is, the car should try to use high gear when driving. When the power is insufficient, you should quickly downshift, and you must not force the stall. If you miss the shift opportunity, you can skip and downshift. 3. Driving according to the slope: When the car goes up a steep slope, it is necessary to choose the appropriate gear according to the slope to keep the engine power sufficient. When the vehicle passes through a short uphill with a small slope, if the road surface is wide and flat and the line of sight is good, inertia can be used to accelerate the uphill.
