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 this warning for a
considerable period, an emergency stop is initi‐
ated (
/
page 205).
If the driver steers, no warning is issued, or the
warning is ended.
If Active Steering Assist detects that a system
limit has been reached, a visual warning is
issued and a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers (
/
page 183).
System limits
Active Steering Assist has a limited steering tor‐
que for lateral guidance. In some cases, the
steering intervention is not sufficient to keep the
vehicle in the lane or to drive through exits.
The system may be impaired or may not function
in the following instances:
R
There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, greatly varying light condi‐
tions or strong shadows on the carriageway.
R
There is glare, e.g. from oncoming traffic,
direct sunlight or reflections.
R
Insufficient road illumination.
R
The windscreen is dirty, misted up, damaged
or covered in the vicinity of the camera, e.g.
by a sticker.
R
No, or several, unclear lane markings are
present for one lane, or the markings change
quickly, for example, in a construction area
or junctions.
R
The lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
R
If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
R
The road is narrow and winding.
R
There are obstacles on the lane or projecting
out into the lane, such as object markers.
The system does not provide assistance in the
following conditions:
R
On tight bends and when turning.
R
When crossing junctions.
R
At roundabouts or toll stations.
R
When towing a trailer.
