Warning lights

Airbag / SRS warning light on

The airbag or SRS (Supplemental Restraint System) light means the system that deploys airbags in a crash has detected a fault. It usually doesn't affect driving, but it means airbags may not deploy properly if you're in an accident.

Symptoms

  • Airbag icon or 'SRS' text lit on the dash
  • Car drives completely normally otherwise
  • Light may have appeared after cleaning under a seat or after minor water exposure

Likely causes

  • CommonSeat belt buckle or seat sensor faultOccupant sensors in the seat can trigger this if wiring is disturbed or a connector is loose.
  • CommonAftermarket seat covers or accessories interfering with sensorsCovers can block or confuse the occupant classification sensor.
  • PossibleCorroded or loose airbag connectorCommon after seat removal for cleaning or repair.
  • PossiblePrevious minor collision that didn't deploy airbagsSensors can register impact even in low-speed events.
  • Less commonFailing clock spring (steering wheel airbag wiring)More common on older or high-mileage vehicles.

What to do

  1. Remove any aftermarket seat covers, especially on the front passenger seat, and see if the light resets after a drive cycle.
  2. Check that seat belts are buckled properly and haven't been recently removed for cleaning.
  3. Think back to whether the seats were recently removed, cleaned, or worked on.
  4. Avoid ignoring this light long-term, since it means airbags may not work correctly in a crash.
  5. Have the code read at a shop, since airbag codes are specific and point to the exact sensor or wiring issue.
  6. Get the flagged connector, sensor, or clock spring repaired by a qualified technician.
  7. Don't attempt to repair airbag wiring yourself; the system stores energy and can deploy unexpectedly.

When to call a pro

See a mechanic or dealer to properly diagnose and repair any airbag system fault; this isn't a DIY repair.

Safety

Use caution

Do not attempt airbag system repairs yourself; the components can deploy with enough force to cause injury even with the car off.
