Start/Stop – Hill Start Assist (HSA)
Start/Stop is a function that temporarily switches off the engine when the vehicle is not moving, for instance in heavy traffic or at a traffic light to help reduce fuel consumption.
When starting on steep hills, HSA (see Transmission – general information) retains pressure on the brake pedal for several seconds after the pedal has been released in order to keep the vehicle at a standstill. The brakes will be released after several seconds or when the driver presses the accelerator pedal. The pedal will return to its normal position somewhat slower than normal.
