DSR (Downhill Speed Regulation)
Function of DSR (Downhill Speed Regulation)
DSR is an aid to assist you when driving down‐
hill. It keeps the speed of travel at the selected
Driving and parking 199
target speed. The steeper the downhill gradient,
the greater the DSR braking effect on the vehi‐
cle. On flat stretches of road and uphill gradi‐
ents, the DSR brakes the vehicle minimally or
not at all.
When DSR is activated and the transmission is in
position h, k or i, DSR controls the driving
speed. The target speed can be set to a value
between 1 mph (2 km/h) and 11 mph
(18 km/h). By braking or accelerating, you can
drive at a higher or lower speed than the target
speed at any time.
DSR is deactivated automatically if you drive at
speeds greater than 28 mph (45 km/h) or select
drive program C or B. The î
sage then appears in the multifunction display.
The status indicator in the multifunction display
®
disappears. You also hear a warning tone.
