The hill-start assist is a variant of hill-holder used by some semi-automatic, clutchless transmissions as well as newer manual transmissions. The system prevents the car from rolling away when trying to pull away on an up or down gradient, simulating a "handbrake hill start" manual drivers will be familiar with. The system engages automatically when a gradient of 3% or more is detected; it then acts to hold the car stationary for two seconds after the brake is released giving the driver time to apply the throttle.

For manual transmission cars, moving off a slope is done by careful clutch control.
