Limitations of Pilot Assist
The Pilot Assist function may have limitations in
certain situations.
The Pilot Assist function is an aid which can help
the driver in many situations. But the driver is at
all times responsible for maintaining a safe dis-
tance to surrounding objects and a correct posi-
tion in the lane.
WARNING
In certain situations, Pilot Assist steering
assistance may have difficulty helping the
driver in the right way or it may be automati-
cally deactivated - in which case, the use of
Pilot Assist is not recommended. Examples of
such situations may be that:
the lane markings are worn, missing or
•
cross each other.
lane division is unclear, for example, when
•
the lanes divide or merge or at exits or in
the event of multiple sets of markings.
edges or other lines than lane markings
•
are present on or near the road, e.g.
kerbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.
the lane is narrow or winding.
•
the lane contains ridges or holes.
•
weather conditions are poor, e.g. rain,
•
snow or fog or slush or impaired view with
poor light conditions, back-lighting, wet
road surface etc.
The driver should also note that Pilot Assist
has the following limitations:
High kerbs, roadside barriers, temporary
•
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact
DRIVER SUPPORT
between the car and such obstacles. The
driver must ensure him/herself that the
car is at a suitable distance from such
obstacles.
The camera and radar sensor does not
•
have the capacity to detect all oncoming
objects and obstacles in traffic environ-
ments, e.g. potholes, stationary obstacles
or objects which completely or partially
block the route.
Pilot Assist does not "see" pedestrians,
•
animals, etc.
The recommended steering input is force
•
limited, which means that it cannot always
help the driver to steer and keep the car
within the lane.
• In cars equipped with Sensus Navigation*,
the function has the option of using infor-
mation from map data, which may result
in varied performance.
Pilot Assist is switched off if the power
•
steering is working with reduced power -
e.g. during cooling due to overheating
(see section "Speed-dependent steering
force").
The driver always has the possibility of correcting
or adjusting a steering intervention imposed by
Pilot Assist and can turn the steering wheel to
the desired position.
