Warning lights of the Nissan Note: what each light means
In the 2 generations of the Nissan Note, the documented faults light up 3 warning lights on the dashboard. The most frequent: airbag light (2 faults), adBlue warning (1 fault) and pollution control faulty (1 fault).
Which warning lights the faults of the Nissan Note trigger
Red ones first, and those that call for stopping. Below each warning light, the documented faults that trigger it, with their pages.
Airbag warning light on
Urgency: Garage soonRedSymbol: a seated person wearing a seat belt with a circle (the inflated airbag) in front; in some cars, the letters SRS or AIRBAG
The airbag warning light means the system has detected a fault and an airbag or seatbelt pretensioner may not deploy in a crash. Causes range from a connector under the seat to the control unit or the airbag itself.
What to do: Have it diagnosed as soon as possible and check with the VIN whether the car has any outstanding airbag recall.
2 documented faults that trigger it in the Nissan Note
- Critical severity: Risk of airbag rupture or abnormal deployment · outside the engine · I
- High severity: Driver's airbag with excess pressure in the inflator (2016 recall) · outside the engine · II
AdBlue system warning
Urgency: Garage soonYellow or amberSymbol: AdBlue system warning in the instrument cluster, yellow or orange at first, usually accompanied by a text message and, later on, a countdown in kilometres
Diesels with selective catalytic reduction (SCR) use AdBlue to cut NOx emissions. A warning with a countdown ("engine will not restart in X km") indicates a low level or a fault in the AdBlue tank, pump, heater or injector. When the countdown reaches zero, the car will not start again.
What to do: If the tank is full and the warning persists, the problem lies with the system. Go to a garage before the countdown ends and keep your receipts in case the fault is covered by a manufacturer campaign.
1 documented fault that triggers it in the Nissan Note
- Medium severity: NOx trap and AdBlue system on the Euro 6 1.5 dCi · 1.5 dCi engine · II
"Pollution control system faulty" message
Urgency: Garage soonYellow or amberSymbol: a text message on the dashboard ("anticontaminación defectuosa" or similar wording, in English "emissions system fault"), sometimes alongside an amber warning light
A common message on Peugeot, Citroën, DS and Opel cars from the Stellantis group. It appears when the ECU detects a fault in a component that controls emissions: the particulate filter, the EGR valve, the sensors, the AdBlue system or, on petrol engines, combustion problems.
What to do: It is not a specific fault but a generic warning. Have the car diagnosed with the right equipment to read the exact code before replacing any part.

A warning light has come on in the Nissan Note: what should I do?
Find which warning light it is on this page and check its urgency. For the others, book an appointment at a garage and have them read the fault code with an OBD reader: it shows which system has failed.
