FORD 2013 Explorer v.4 - Manual (Page 272)

While the system is on, the color of the lane markings will change to
indicate the system status.
Gray: Indicates that the system is temporarily unable to provide a
warning or intervention on the indicated side(s). This may be because:
• the vehicle is under the activation speed
• the turn indicator is active
• the vehicle is in a dynamic maneuver
• the road has no or poor lane markings in the camera field-of-view
• the camera is obscured or unable to detect the lane markings due to
environmental conditions (e.g. significant sun angles or shadows,
snow, heavy rain, fog), traffic conditions (e.g. following a large vehicle
that is blocking or shadowing the lane), or vehicle conditions (e.g.
poor headlamp illumination).
See Troubleshooting for additional information.
Green: Indicates that the system is available or ready to provide a
warning or intervention, on the indicated side(s).

keeping aid intervention.

keeping alert warning.
