Which gear should be used when climbing a slope?

[Harmony]

Introduction to gear selection when climbing a slope: 1. When going uphill: The gear should be determined based on the engine RPM. If the engine RPM drops below 2000 while climbing in third gear, you should downshift to second gear. If the slope is very steep and the vehicle is fully loaded, first gear should be used to climb. 2. When going downhill: The gear depends on the steepness of the slope. Generally, for gentle downhill slopes on highways, fifth gear with brake control can be used to maintain speed, but this also depends on the current speed. If the engine is lugging, downshift should be performed. For moderately steep slopes, third or fourth gear with brake control is appropriate, again depending on the current speed. For very steep slopes, second gear with brake control should be used. First gear is generally not used when going downhill.
