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 centre of
the 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.

Ø Green: activated and active
Ø Red, flashing: prompt to the driver to

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 grey 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
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 261).
/
The warning is not issued or is stopped as soon as
the system detects that the driver has touched
the steering wheel.
Touch detection may be limited or inoperative in
the following situations:
The driver is wearing gloves.
R
There is a steering wheel cover on the steering
R
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 recognise
dangers ( page 237).

System limits
Active Steering Assist has a limited steering tor-
1
que for lateral guidance. In some cases, the steer-
ing intervention is not sufficient to keep the vehi-
cle in the lane.
