If the Intelligent Forward Collision Warning (I-FCW) system on the Nissan Sentra malfunctions, the system will automatically deactivate. A warning chime will sound, the Automatic Emergency Braking (AEB) with Pedestrian Detection warning light (orange) will illuminate, and the warning message [Malfunction] will be displayed in the vehicle information display to alert the driver.
Action to take
If the warning light (orange) illuminates, safely stop the Nissan Sentra in an appropriate location, turn the engine off, and then restart the engine. If the warning light continues to remain illuminated after restarting, have the I-FCW system inspected. It is recommended that you visit an authorized NISSAN dealer for proper diagnosis and service.
System maintenance

The radar sensor A for the I-FCW system is located on the front of the Nissan Sentra.
To ensure reliable operation of the Intelligent Forward Collision Warning system, observe the following maintenance guidelines:
