The following is an introduction to the gears on steep slopes on manual transmission vehicles: 1. For general urban slopes, vehicles with large displacement can go into third gear. For fast uphill speeds, they can even go directly into fourth gear. For vehicles with small displacement, it can be used directly in fourth gear. Car second gear. The underground parking lot has a steep slope, so use second gear. 2. The gear used by a manual transmission car when going uphill is related to the vehicle speed and the slope of the slope. If the slope of the slope is large, the lower gear 2-3 should be used (according to the vehicle speed at the time). Large-displacement cars also You can increase the accelerator in third gear to go uphill. For small-displacement vehicles, use second gear to ensure sufficient traction. 3. Going up and down the elevated road, although it is very steep, the speed is at least 40 yards, and 4th and 5th gears are no problem. Of course, you must use first gear and handbrake when starting on a hill. If the brakes are applied, the clutch is semi-linked, which can easily cause stalling. For general slopes (about 15 degrees), it is enough to follow the car in 2nd gear. Steep grade 1 (usually found in underground garages). On a slope greater than 30 degrees, the accelerator cannot be fully released, and small-displacement vehicles are prone to stalling. When turning on a steep slope, you should also give more fuel. The turning resistance will be large and the engine will stall easily.
