Final answer:
The Hill Start Assist feature in the 2021 NV200 helps prevent the vehicle from rolling backwards when starting on an incline or hill.
Step-by-step explanation:
The benefit of the 2021 NV200's Hill Start Assist is that it helps prevent the vehicle from rolling backwards when starting on an incline or hill.
This feature is especially useful in situations where the driver needs to quickly transition from braking to accelerating, such as in stop-and-go traffic or when navigating steep hills.
By automatically holding the brakes for a few seconds after the driver releases the brake pedal, Hill Start Assist gives the driver more time to switch from the brake to the accelerator without worrying about rolling backwards.
