Lane Keeping Assist is designed to detect the lane markers on the road with a front view camera on the windshield, and may assist the driver’s steering to potentially help keep the vehicle in the lane. When turned on, the instrument cluster indicator will initially illuminate gray . It will remain gray when the vehicle is traveling slower than 40 mph or when the system does not detect the lane markers. When the system detects the lane markers and can assist the steering, the Lane Safety icon
will illuminate green.
If LKA detects that you are moving outside of your lane, LKA may give an audible warning and display a Lane Departure Warning on the Instrument Cluster. If the vehicle continues to move outside of the lane, LKA may provide steering inputs, trying to prevent the vehicle from moving outside its lane.
When enabled in Vehicle Settings, press and hold the Lane Driving Assist button
to turn on or off.

When the front-view camera does not detect the lane traveled in the lanes are not illuminated, shown below.
When the front-view camera detects the lane traveled in, both lanes are illuminated, shown below. 
When the front-view camera detects the vehicle moving outside of the lane being traveled in, a red indicator will illuminate either on the left or right lane, shown below.
