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 1 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 the warning for a
considerable period, the system can initiate an
emergency stop ( page 203).
/
The warning does not occur or stops as soon as
the system detects that the driver is touching or
steering 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 182).

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 or to drive through exits.
The system may be impaired or may not function
in the following instances:
There is poor visibility, e.g. due to snow, rain,
R
fog, heavy spray, greatly varying light condi-
tions or strong shadows on the carriageway.
There is glare, e.g. from oncoming traffic,
R
direct sunlight or reflections.
