Forward Collision-Avoidance Assist Malfunction And Limitations
2C_FCADysfunction
When Forward Collision-Avoidance Assist is not working properly, the "Check Driver Assistance system." warning message may appear, and the
2C_CameraRadarDisableWarning
If the front view camera, front radar, bumper, or sensor is covered or blocked by foreign material, such as snow, rain, or dirt, or when a trailer or hitch mounted carrier is installed, the detecting performance may decrease and temporarily limit or disable Forward Collision-Avoidance Assist.
The "Driver Assistance system limited. Camera obscured." or the "Driver Assistance system limited. Radar blocked." warning message may appear, and the
The function operates normally when such foreign material, trailer, or carrier is removed, and the engine is restarted.
If Forward Collision-Avoidance Assist does not operate normally after anything covering or blocking the sensors is removed, have your vehicle inspected by an authorized retailer of Genesis Branded products.
-
Forward Collision-Avoidance Assist may not operate properly even if there is no warning message or warning light on the instrument cluster.

-
If the vehicle is turned off and restarted while the camera is blocked or malfunctioned, the condition is maintained and may not operate properly.
