Airbag Warning Light (SRS) on a DS DS 4
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 DS DS 4
The airbag (SRS) light on a DS DS 4 means the supplemental restraint system has logged a fault. When it is on, one or more airbags or pretensioners may not deploy in a crash — a genuine safety concern even though the car drives normally.
How Urgent Is the Airbag Warning Light (SRS)?
How worried should you be? For the Airbag Warning Light (SRS) on a DS DS 4, the urgency is high.

If the DS DS 4 still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Frequently Asked Questions
Why is the Airbag Warning Light (SRS) on in my DS DS 4?
On a DS DS 4, the Airbag Warning Light (SRS) comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Airbag Warning Light (SRS) on?
Short answer: sometimes, but not indefinitely. Given this indicator's high priority, respect the warning colour and the car's behaviour. When in doubt with your DS DS 4, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Airbag Warning Light (SRS) on a DS DS 4?
Cost varies widely because the Airbag Warning Light (SRS) can stem from several causes on a DS DS 4. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Airbag Warning Light (SRS) reset itself on a DS DS 4?
If the trigger was temporary, a DS DS 4 may turn the Airbag Warning Light (SRS) off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
