What does it mean to downshift?

[VanJosiah]

Downshifting means forced gear reduction, also known as emergency downshifting. The principle is to use engine braking to decelerate, which is generally used when the brakes fail or the braking wheels malfunction. Operation method of downshifting: It requires the double-clutching technique while revving the engine in neutral to facilitate smooth gear shifting. Depress the clutch to shift into neutral, release the clutch and rev the engine hard, depress the clutch again to shift into a lower gear, then release the clutch. Usage scenarios of downshifting: Downshifting can be used when brakes fail, tires blow out, or when descending long steep slopes to reduce vehicle speed through engine braking. Additionally, during icy or snowy weather when roads are very slippery, braking may cause skidding. Driving in a lower gear is a safer alternative.
