The Nissan Forward Emergency Braking (FEB) system is a crucial safety feature that helps prevent collisions. However, when the warning light stays on, it can indicate a problem. This guide will help you understand and reset the FEB warning light in your Nissan vehicle.

Understanding the FEB Warning Light

The FEB warning light typically illuminates when there's an issue with the system. It may appear as a vehicle icon with a star or exclamation point. When lit, it means the FEB system is either disabled or malfunctioning.

Common reasons for the FEB light to stay on include:

  • System turned off manually
  • Dirty or obstructed radar sensor
  • Electrical or wiring issues
  • Software glitches
  • Low brake fluid
