Usage
Functional restriction
Lane Assist helps to keep the vehicle in the lane. It is
based on the boundaries of a lane. These can include
boundary lines, road edges or objects such as curbs
and possibly traffic cones.
The system function may be restricted in the follow-
ing cases.
The field of view of the sensor is limited by a dirty
screen or an obstacle or a preceding vehicle.
In the event of unfavourable weather conditions.
When driving through a sharp bend.
When driving on a steep road or in ruts.
When the driving lane is too narrow.
▶
The system is intended primarily for use on high-
ways.

Functionality
As the vehicle approaches a lane marking, the sys-
tem executes a steering movement in the opposite
direction from the lane marking. The steering inter-
vention can be overridden manually.
When driving through construction sites.
WARNING
Risk of incorrect steering intervention!
Certain objects or markings on the roadway can be
incorrectly recognized as boundary lines.
No system intervention occurs when changing lane
with the turn signal on.
Always keep your hands on the steering wheel and
be prepared to override the steering intervention.
