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 refer‐
ence.
% Depending on the country, in the lower
speed range Active Steering Assist can use
the surrounding traffic as a reference. If nec‐
essary, Active Steering Assist can then also
provide assistance when driving away from
the center of the lane, for example, to form a
rescue lane.
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.

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
vehicle 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 steer‐
ing wheel, display 1 appears. If the driver still
does not steer the vehicle, a warning tone
sounds in addition to the visual warning mes‐
sage.
If the driver does not react to the warning for a
considerable period, the system can initiate an
emergency stop ( page 168).
/
The warning is not issued or is stopped when the
driver gives confirmation to the system:
The driver steers the vehicle.
