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
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.
•
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.
Steep roads and/or heavy load
Bear in mind that Pilot Assist is primarily
intended for use when driving on level road surfa-
ces. The function may have difficulty in keeping
the correct distance from the vehicle ahead when
driving on steep downhill slopes - in which case,
be extra attentive and ready to brake.
•
Do not use Pilot Assist if the car has a heavy
load or a trailer is connected to the car.
NOTE
Pilot Assist cannot be activated if a trailer,
bicycle rack or similar is connected to the
car's electrical system.
Miscellaneous
•
Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which
has some general limitations, see the section
"Limitations for radar unit".
