Function of Active Traffic Jam Assist
%
Active Traffic Jam Assist is country-depend‐
ent and only available for vehicles with the
Driving Assistance Plus Package.
Active Traffic Jam Assist helps you when in traf‐
fic jams on multi-lane roads with separate carria‐
geways by automatically pulling away within up
to 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 systems and your
responsibility; you may otherwise fail to recog‐
nise dangers (/ page 203).
Active Traffic Jam Assist activates automatically
