Active Stop-and-Go Assist requires you, as the
driver, to keep your hands on the steering wheel
at all times so that you are able to intervene at
any time to correct the course of the vehicle and
keep it in lane.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 237).

DSR (Downhill Speed Regulation)
▌Function of DSR (Downhill Speed Regulation)
DSR is an aid to assist you when driving downhill.
It keeps the speed of travel at the selected target
speed. The steeper the downhill gradient, the
greater the D S R braking effect on the vehicle.
On flat stretches of road and uphill gradients, 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 2 km/h and 18 km/h. By braking or
accelerating, you can drive at a higher or lower
speed than the target speed at any time.
If you drive faster than 45 km/h or change the
driving programme (except in F/), DSR
switches off automatically. The î
appears in the driver's display. The status indica-
tor in the driver's display goes out. You also hear
a warning tone.
▌Information on DSR
& WARNING Risk of skidding and accident
when DSR is activated on slippery road
surfaces
If the driven speed and the target speed differ,
the wheels may lose traction.
Take into account the road surface and
#
the difference between the driving speed
and target speed before activating DSR.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 237).
/
You are always responsible for keeping control of
the vehicle and for assessing whether the downhill
gradient can be negotiated. Depending on road
surface and tyres, DSR may not always be able to
keep to the target speed. Select a target speed
suitable for the environmental conditions and also
off message
apply the brakes yourself if required.
