Ø
Red, flashing: prompt to the driver to
actively confirm or transition from active to
passive status, system limit detected
%
During the transition from active to passive
status, the Ø symbol is shown as enlarged
and flashing. Once the system is passive, the
Ø symbol is shown as gray in the driver's
display.
Contact 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, an optical warning is given first. Display 1
appears in the driver's display. If the driver still
does not steer the vehicle, or gives no confirma-
tion to the system, a warning tone sounds in addi-
tion 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 270).
The warning is not issued or is stopped as soon as
the system detects that the driver has touched
the steering wheel.
The touch detection may be limited or may not
function if there is no direct contact between the
hand and the steering wheel, e.g. when wearing
gloves or if there is a steering wheel cover on the
steering wheel.
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 recognize
dangers (

page 252).
System limits
Active Steering Assist has a limited steering tor-
que for lateral guidance. In some cases, the steer-
ing intervention is not sufficient to keep the vehi-
cle in the lane.
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 ambient light
or strong shadows on the road.
R
There is glare, e.g. from oncoming traffic,
direct sunlight or reflections.
