When driving on highways and freeways with white or yellow lines, this function alerts the
driver when the vehicle might depart from it s lane and provides assistance by operating
the steering wheel to keep the vehicle in its lane. Furthermore, the system also provides
steering assistance when dynamic radar cruise control with full-speed range is operating
to keep the vehicle in its lane.
The LKA system recognizes visible white or yellow lines with the front camera on the
upper portion of the front windshield.
