The current speed is stored. When stationary, 4 km/h or the minimum possible speed for each gear range is stored. DSR maintains the stored speed on the downhill gradient and brakes automatically.
When DSR is activated and the vehicle pulls away, accelerates or brakes on an incline, the speed set corresponds to the speed at which the accelerator or brake pedal is released or the cruise control lever is operated during DSR regulation. This is only the case if you are not driving faster than 18 km/h.
