Hill-start & Downhill Assist Control

Our Downhill Assist Control (DAC) automatically controls the brakes to maintain a constant low speed when descending slopes, helping reduce wheel lock, while Hill-start Assist Control (HAC) helps make rollbacks a thing of the past, by automatically applying the brakes for approximately five seconds when starting off on an incline.
