Airbag Warning Light (SRS) on a Cupra Formentor
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Airbag Warning Light (SRS) Means on a Cupra Formentor
On the Cupra Formentor, an illuminated airbag light indicates the SRS module found a problem in the airbag circuit, a seat-belt pretensioner, or a crash sensor. The system disables itself to avoid an unintended or failed deployment.
How Urgent Is the Airbag Warning Light (SRS)?
Urgency level for this indicator on the Cupra Formentor: high. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Airbag Warning Light (SRS) appeared, how the Cupra Formentor is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

The step-by-step approach below is the same logical order a professional follows on the Cupra Formentor: confirm the basics, read the stored codes, then target the actual fault.
- Check that seats have not been moved with connectors disturbed

Is It Safe to Drive With the Airbag Warning Light (SRS) On?
Whether it is safe to keep driving your Cupra Formentor with the Airbag Warning Light (SRS) on comes down to urgency (high) and behaviour.

Why is the Airbag Warning Light (SRS) on in my Cupra Formentor?
The Airbag Warning Light (SRS) illuminates on a Cupra Formentor when the vehicle detects a condition in the related system that is outside its normal range.

Can I keep driving with the Airbag Warning Light (SRS) on?
For a Cupra Formentor, a steady amber Airbag Warning Light (SRS) with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.

Will the Airbag Warning Light (SRS) reset itself on a Cupra Formentor?
Occasionally, yes — a Cupra Formentor can extinguish the Airbag Warning Light (SRS) by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
