Condition A
When the radar sensor picks up interference from another radar source, making it impossible to detect a vehicle ahead, the PFCW system is automatically turned off.
The FEB system warning light (orange) will illuminate.
Action to take
When the above conditions no longer exist, the PFCW system will resume automatically.
Condition B
When the sensor area of the front bumper is covered with dirt or is obstructed, making it impossible to detect a vehicle ahead, the PFCW system is automatically turned off.
The FEB system warning light (orange) will illuminate and the "front radar obstruction" warning message will appear in the vehicle information display.

Illustration D
Action to take
If the warning light (orange) comes on, stop the vehicle in a safe place, place the shift lever in the P (Park) position and turn the engine off. Clean the radar cover on the lower grille with a soft cloth, and restart the engine. If the warning light continues to illuminate, have the PFCW system checked. It is recommended that you visit a NISSAN dealer for this service.
NOTE:
If the FEB system stops working, the PFCW system (if so equipped) will also stop working.
