DRIVER SUPPORT
||
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.
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, with a heavy
load or with a trailer - in which case, be extra
attentive and ready to brake.
