Lane Assist
Usage
Lane Assist helps to keep the vehicle within the lane.
It is based on the boundaries of a lane. These may in-
clude lane markings, road edges or objects such as
curbs or possibly traffic cones.
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.
No system intervention occurs when changing lane
with the turn signal on.
