Function of Active Stop-and-Go Assist
Active Stop-and-Go Assist helps you when in
traffic jams on multi-lane roads with separate
roadways by automatically pulling away within
60 seconds and with moderate steering maneu‐
vers. It orients itself using the vehicle in front
and lane markings. Active Stop-and-Go Assist
automatically maintains a safe distance from the
vehicle in front and vehicles cutting in.
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 sys‐
tems and your responsibility; you may otherwise
fail to recognize dangers ( page 167).
/
Active Stop-and-Go Assist activates automati‐
cally as soon as all of the requirements are met:
The ¬ status display appears in the instru‐
ment cluster when the function is active.
Requirements:
