Warning lights of the Fiat Stilo: what each light means
In the Fiat Stilo, the documented faults light up 3 warning lights on the dashboard. The most frequent: engine warning light (2 faults), airbag light (1 fault) and DPF warning light (1 fault).
Which warning lights the faults of the Fiat Stilo 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.
1 documented fault that triggers it in the Fiat Stilo
- Medium severity: Electrical and electronic faults in the multiplex system · outside the engine
Engine fault warning light (check engine)
Urgency: Garage soonYellow or amberSymbol: outline of an engine seen from the side, in yellow or orange
The orange engine-shaped warning light comes on when the ECU detects a fault affecting combustion or emissions. If it flashes, it usually points to misfires that can damage the catalytic converter.
What to do: If it stays on steadily, you can drive gently to a garage and ask for a fault code read-out. If it flashes or you notice a loss of power, slow down and get to a garage as soon as possible.
2 documented faults that trigger it in the Fiat Stilo
- High severity: Intake manifold flap failure (swirl effect) · 1.9 JTD/Multijet and 2.4 JTD engine
- Medium severity: EGR valve blocked by carbon · 1.9 JTD/Multijet and 2.4 JTD engine
Particulate filter warning light (DPF)
Urgency: Garage soonYellow or amberSymbol: particulate filter symbol on the dashboard, normally amber; its design varies by manufacturer
On modern diesels it means the particulate filter is clogged with soot and has not been able to regenerate. It is common in cars used mostly for short town journeys, although it can also be caused by a sensor or by an injection or EGR fault.
What to do: If the handbook allows it, a 20-minute drive on a motorway at a steady speed can complete the regeneration. If the light stays on or you lose power, go to a garage.

- Medium severity: Particulate filter (DPF) clogging in urban use · 1.9 JTD/Multijet and 2.4 JTD engine

A warning light has come on in the Fiat Stilo: 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.
