Function of Active Traffic Jam Assist
Active Traffic Jam Assist helps you when in traf‐
fic jams on multi-lane roads with separate carria‐
geways by automatically pulling away within
60 seconds and with moderate steering
manoeuvres. It orients itself using the vehicle in
front and lane markings. Active Traffic Jam
Assist automatically maintains a safe distance
from the vehicle in front and vehicles cutting in.
Active Traffic Jam 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 sys‐
tems and your responsibility; you may otherwise
fail to recognise dangers ( page 229).

Active Traffic Jam Assist activates automatically

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
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 2 km/h and 18 km/h. By braking or
