Active Steering Assist
▌Function of Active Steering Assist
Active Steering Assist is only available up to a
speed of 130 mph (210 km/h). The system helps
you to stay in the center of the lane by means of
moderate steering interventions. Depending on
the speed driven, Active Steering Assist uses the
vehicles ahead and lane markings as a reference.
%
Depending on the country, in the lower speed
range Active Steering Assist can use the sur-
rounding traffic as a reference. If necessary,
Active Steering Assist can then also provide
assistance when driving outside the center of
the lane, for example, to form an emergency
corridor.
If the detection of lane markings and vehicles
ahead is impaired, Active Steering Assist switches
to passive mode. The system provides no support
in this case.

Active Steering Assist may be unavailable.
Steering and touch detection
The driver is required to keep their hands on the
steering wheel at all times and be able to inter-
vene at any time to correct the course of the vehi-
cle and keep it in lane. The driver must expect a
change from active to passive mode or vice versa
at any time.
If the system detects that the driver has not
steered the vehicle for a considerable period of
time or has removed their hands from the steering
wheel, display

appears. If the driver still does
not steer the vehicle, a warning tone sounds in
addition to the visual warning message.
If the driver does not react to this warning for a
considerable period, an emergency stop is initi-
ated (
page 196).
/
The warning is not issued or is stopped as soon as
the system detects that the driver is touching or
steering the steering wheel.
Touch detection may be limited or may not func-
tion if there is no direct contact between hand
