Page: 224 / 612

The warning message does not appear or disap‐
pears if one of the following conditions are met:
R
The driver steers the vehicle.
R
The driver presses a steering wheel button or
operates Touch Control.
Active Steering Assist is only an aid. The driver is
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane. Before changing lanes,
the driver must make sure that the neighbouring
lane is free (glance over the shoulder).
System limitations
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 past exits.
The system may be impaired or may not function
in the following instances:
R
In snow, rain, fog, heavy spray, if there is
glare, direct sunlight, greatly varying light
conditions, reflections or strong shadows on
the carriageway.
R
Insufficient road illumination.
R
The windscreen in the area of the camera is
dirty, misted up, damaged or covered.
R
Absence of lane markings, or several unclear
lane markings, or if the markings change rap‐
idly.
R
The distance to the vehicle in front is too
small and the lane markings thus cannot be
detected.
R
The road is narrow and winding.
R
Obstacles on the lane or projecting out into
the lane.
The system does not provide assistance in the
following conditions:
R
On tight bends, junctions, toll stations,
roundabouts and when turning.
R
When towing a trailer.
R
When actively changing lane without switch‐
ing on the turn signal.
R
When the tyre pressure is too low.

tion to traffic conditions.
