DSR is an aid toassist you when driving downhill.

speed. The steeper the downhill gradient, the
gr eater the DSR braking e.ect on theve hicle. On
0at st retches of road and uphill gradients, the
DSR brakes theve hicle minimally or not at all.
When DSR is activated and the transmission is in
position h,kori, DSR controls the driving
speed. The targetspeed can be set toava lue
between 2 km/h and 18 km/h. By braking or
accelerating, you can drive at a higher or lo wer
