The airbag warning light (also known as the SRS light) indicates a fault in the vehicle’s passive safety system. Unlike some warning lights, this one should never be ignored.
What Does an Illuminated Airbag Light Mean?
The SRS (Supplemental Restraint System) includes:
- Front and side airbags
- Seatbelt pretensioners
- Crash sensors
If the light remains on, it means that one of these components has a fault.
Is It Serious?
Yes.
- The airbag may not deploy in the event of an accident
- A pretensioner may be disabled
- Occupant protection is reduced
Can You Continue Driving?
The vehicle remains drivable, but the safety system may be partially inactive. A quick diagnosis is strongly recommended.
Most Common Causes
1. Poorly Connected Seat Connector
Very common after a seat adjustment.
2. Weak Battery
An unstable voltage can trigger an SRS fault.
3. Faulty Crash Sensor
Less common but critical.
4. Steering Wheel/Clockspring Switch
Can cause a driver’s airbag fault.
How to Diagnose?
- Reading codes via SRS-compatible OBD tool
- Checking connectors under the seats
- Battery check
Repair Costs
| Service | Estimated Cost |
|---|---|
| Reconnect Connector | £50 to £150 |
| Steering Wheel Switch | £200 to £500 |
| Airbag Sensor | £300 to £800 |
Key Takeaway
An illuminated airbag light means your protection system may not function correctly in the event of an accident. It is essential to have the vehicle checked promptly.
