What gear should be used when going uphill in an underground garage?

[MacJulia]

When going up a steep slope in an underground parking garage, use second gear. The gear used for a manual transmission car when going uphill is related to both the vehicle speed and the slope gradient. For steeper slopes, a lower gear such as 2nd or 3rd should be selected (depending on the current speed). High-displacement vehicles can also use third gear with increased throttle to climb, while small-displacement vehicles should use second gear to ensure sufficient traction. Below are the gear usage recommendations for different slope gradients: 1. For high-displacement vehicles and gentle slopes, drivers can use 2nd or 3rd gear for climbing. 2. For low-displacement vehicles and gentle slopes, second gear should suffice, and third gear may not be necessary for some slopes—lower gears are adequate. 3. For very steep slopes, regardless of the vehicle's displacement, it is recommended to use first gear for climbing, as first gear provides the maximum torque. If a slope cannot be climbed in first gear, other gears will not help either.
