What should I do when the airbag warning stays on?

Treat a persistent airbag or SRS warning as a reason to arrange professional inspection, rather than as a reminder you can clear or ignore. For example, the 2026 Toyota Prius manual says its SRS warning indicates a malfunction in the airbag system or seat-belt pretensioner system and directs the owner to have the vehicle inspected by a Toyota dealer immediately. Follow the instructions for your own vehicle: the right provider and guidance may depend on its make, model and year. [S1]

The warning alone does not tell you which part has failed or what repair is needed. Avoid guessing at a cause.

No. Don’t inspect, disconnect, test or repair SRS wiring or components yourself. The cited Toyota manual identifies sensors, airbags, related wiring and power sources among areas potentially involved, but it does not say which one is faulty in a particular vehicle or provide a universal repair. That uncertainty is a reason to leave assessment to a qualified professional, not a reason to try parts one by one. [S1]

Use the vehicle’s manual to find its specific warning guidance, and tell the service provider that the warning remains on.

Write down observations you can make without touching the airbag system. A useful briefing includes the vehicle’s make, model and year; when you first noticed the warning; whether it stays lit or comes and goes; and what else you observed at the time. If you are unsure whether a detail matters, label it as an observation rather than a diagnosis.

Copyable example, with placeholders: “Vehicle: [year, make, model]. Airbag/SRS warning: [first noticed on date or approximate time]. It [stays on / appears intermittently]. Other observations: [describe what you saw or heard, or write ‘none noticed’]. I have not inspected or changed SRS components. Please advise on an inspection for this model.”

Record what you can see separately: the exact warning or symbol, whether it remains on, and when any other warning appeared. Don’t claim that one light caused another unless a qualified professional confirms it. Share the observations with the service provider and ask what inspection is appropriate for your vehicle.

The source cited here supports getting the vehicle inspected; it does not establish a universal repair, identify a failed part, or explain what every vehicle’s warning behavior means. [S1]

Use this fill-in template when you call or make an appointment:

“Please assess the airbag/SRS warning on my [year, make, model]. I first noticed it [when]. It [stays on / appears intermittently]. Other observations: [brief description]. I have not worked on the SRS system. What model-specific inspection should I arrange, and what should I do while waiting for the appointment?”

If you’re unsure how to describe the light, say that you’re unsure and give your best plain-language description. This keeps the briefing useful without guessing at a diagnosis.
