I recently bought a Mk2 2014 Qashqai Tekna Dig-T. The Forward Emergency Braking system light is illuminated the whole time while the engine is on. According to the manual, this is either because the FEB system is switched off, or because there is a fault. However, I have never used this function, and when I go to the Driver Assistance menu, the Driving Aids (and Driver Attention) options are greyed out and cannot be selected, so there seems to be no way to turn it on, even though I'm fairly sure my car does have this function. But my reading of the manual is that if there were a fault, there would also be other warnings displayed. Therefore I'm not sure why the warning light is showing or what it means, or why I can't turn on the FEB. Any help would be very gratefully received, thank you!

That shows FEB switched OFF certainly and either by the system or the driver.

The system faults (errors) are many and about 25 (see below). Diagnosing the problem requires Nissans Consult tool.

The radar sensor at the front of the car could be defective or dirty...maybe something to check first. Its on the driver side below the headlamp and behind the front body part.

If the radar sensor has failed the FEB system defaults to FAIL SAFE and illuminates the collision indicator you see. Other lamps may illuminate due to DTCs below.

Errors (DTCs): (read Radar for Laser)

I had this fault on my Mk2 2016 Qashqai Dig-T. In my case the camera located behind the rear view mirror was faulty. The repair was over £1,000 but free to me (under warranty). Another symptom of this fault is the inability to read and display traffic signs (essentially speed limits).

Thank you both for taking the time to respond. Clearly this could have a number of causes and needs further investigation at a dealer. Thanks again.
