Peugeot Airbags warning lamp lit in car: workshop check
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
A fixed orange Airbags warning lamp on a Peugeot signals a fault in one of the airbags (front, lateral or curtain) or in the seat belt pyrotechnic pretensioners. Contact a Peugeot dealer or a qualified workshop promptly, because the airbags may not deploy in a serious collision.
Safety first
Stop and check this first
- Never remove, pierce, strike or tamper with the steering wheel, airbag modules, seat belt pretensioners, front door side impact sensors or under-seat wiring, and never bypass or disable any part of the SRS to hide the warning lamp: all work must be carried out only by a Peugeot dealer or a qualified workshop.
- Do not install a rearward-facing child seat on the front passenger seat when the Airbags warning lamp is lit (even if the deactivation switch is set to OFF), and bear in mind that the airbags may not deploy in the event of a serious impact until repaired.
Safe checks you can perform
- Verify whether the orange Airbags lamp stays fixed after starting
- Do not use a rearward-facing child seat in the front while the lamp is lit
- Visually check seat covers, front doors and roof grab handles without touching wiring

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Diagnostic readout of the airbag and pretensioner control unit
What they doThe Peugeot dealer or qualified workshop connects diagnostic equipment to read the fault memory and pinpoint which airbag circuit, pyrotechnic pretensioner or side impact sensor logged the fault.
They must show youthe diagnostic report showing the specific fault code stored in the airbag and pretensioner control unit.
In writingthe stored fault codes, the affected airbag, pretensioner or impact sensor circuit, and whether codes were cleared before or after repair.
Repair or replacement of faulty door impact sensors, pretensioners or airbag modules
What they doFollowing pyrotechnic safety procedures, the technician repairs or replaces the affected front door side impact sensor, seat belt pyrotechnic pretensioner or airbag unit.
They must show youthe replaced sensor or restraint component and the instrument panel with the Airbags warning lamp extinguished after starting.
In writingthe parts replaced, the post-repair restraint system check, and confirmation that no airbag or pretensioner circuit was bypassed or disabled.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Verify whether the orange Airbags lamp stays fixed after starting
- Who:
- you, from the driver's seat when starting the car.
- How:
- switch on the ignition, watch the initial bulb check, and see whether the orange Airbags warning lamp stays lit once the engine is running, alone or with an audible signal and message.
- Result that matters:
- confirming an active fault in the airbag or pyrotechnic seat belt pretensioner system.
- If the warning lamp stays lit:
- arrange an inspection at a Peugeot dealer or qualified workshop right away, as the airbags may not deploy in a serious impact.
- If the vehicle has recently been in an impact or recovered after theft:
- the handbook requires having the airbag and seat belt systems checked even if no external damage is visible.
- Evidence to keep:
- photo of the instrument panel with the engine running and the Airbags warning lamp illuminated.
Evidence: Handbook Peugeot 208 edition 01-20 (en-GB)
Do not use a rearward-facing child seat in the front while the lamp is lit
- Who:
- you, before carrying passengers or fitting a child restraint.
- How:
- check the front passenger airbag ON/OFF indicator and follow the explicit rule in the handbook: a rearward-facing child seat may only be installed on the front passenger seat with the switch in 'OFF' if there is no fault with the airbags (Airbags warning lamp off).
- Result that matters:
- keeping children safe by placing any child seat on the rear seats until the airbag fault is repaired.
- If a rearward-facing child seat was on the front passenger seat:
- move it to an approved rear seat position immediately.
- If passengers are travelling in the car:
- make sure everyone wears their seat belt properly, sits upright, and keeps feet and objects off the dashboard and away from the doors.
- Evidence to keep:
- check of the passenger airbag switch state and confirmation that any child seat is secured in the rear.
Evidence: Handbook Peugeot 208 edition 01-20 (en-GB)
Visually check seat covers, front doors and roof grab handles without touching wiring
- Who:
- you, by visual inspection only and without touching any SRS parts or cables.
- How:
- without dismantling anything, check whether non-approved seat covers or clothing have been placed on the front seat backrests (where lateral airbags sit), whether objects are attached to the steering wheel, dashboard or roof, whether the roof grab handles (which help secure the curtain airbags) were removed, or whether a front door panel was dented or had trim work done.
- Result that matters:
- gathering useful background information for the technician without disturbing any airbag or pretensioner components.
- If loose items or unapproved slip-on covers are blocking deployment zones:
- remove only the loose external items without touching any wiring and report any door damage to the workshop.
- If everything is original and undamaged:
- leave all testing strictly to the Peugeot dealer or qualified workshop.
- Evidence to keep:
- notes on any recent front door impact or interior trim work to share with the workshop.

What it means
In the Peugeot 208 handbook (edition 01-20), the orange 'Airbags' warning lamp comes on for a few seconds at ignition and should go out once the engine starts; if it remains fixed on, there is a fault with one of the airbags or seat belt pyrotechnic pretensioners and step (3) applies: contact a Peugeot dealer or a qualified workshop to have the system checked. The lamp also comes on whenever a pyrotechnic pretensioner or airbag has been triggered in an impact. Other Peugeot models and restraint layouts may differ, and the warning lamp alone does not prove which airbag, sensor or pretensioner is at fault.

Symptoms and causes
Probable causes · in order
- Fault in an airbag module or seat belt pyrotechnic pretensionerCommon
An electrical or circuit fault affecting the front, lateral or curtain airbags, or the pyrotechnic pretensioners on the front or outer rear seat belts, keeps the warning lamp lit.
Evidence: Handbook Peugeot 208 edition 01-20 (en-GB)
- Damaged front door or work on the front door interior trimPossible
The Peugeot 208 handbook notes that the front door panels house side impact sensors and that a damaged door or unauthorised or incorrectly executed work on the front doors or trim can compromise those sensors.
Evidence: Handbook Peugeot 208 edition 01-20 (en-GB)
- Previous deployment of pretensioners or airbags in an impactLess common
After an impact, even if a pyrotechnic pretensioner triggered independently of airbag deployment, the airbag warning lamp stays on until the system is inspected and replaced by a workshop.
Evidence: Handbook Peugeot 208 edition 01-20 (en-GB)
