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. Active
Steering Assist cannot provide the driver with
steering assistance at traffic circles, T-intersec‐
tions, intersections, toll stations or turns, for
example.
The system may be impaired or may not function
in the following instances:
In snow, rain, fog, heavy spray, if there is
R
glare, direct sunlight, greatly varying light
conditions, reflections or strong shadows on
the carriageway.
Insufficient road illumination.
R
The windshield in the area of the camera is
R
dirty, fogged up, damaged or covered.
Absence of lane markings, or several unclear
R
lane markings, or if the markings change rap‐
idly.
The distance to the vehicle in front is too
R
small and the lane markings thus cannot be
detected.
The carriageway is narrow and winding.
R
Obstacles on the lane or projecting out into
R
the lane.
The system does not provide assistance in the
following conditions:
On tight bends, traffic circles and when turn‐
R
ing.
If you actively change lane without switching
R
on the turn signal indicator.
& WARNING Risk of accident if Active
Steering Assist unexpectedly stops func‐
tioning
If the system limitations of Active Steering
Assist are reached there is no guarantee that
the system will remain active or will keep the
vehicle in lane.
Always keep your hands on the steering
#
wheel and observe the traffic carefully.
Always steer the vehicle paying atten‐
#
tion to traffic conditions.
