Description
Professional-grade passenger pyrotechnic seatbelt designed for the Citroën C4 5-door and compatible Peugeot 307 models. This SRS pretensioner assembly tightens the belt instantly in a collision to reduce occupant movement and improve restraint performance. Supplied with OEM reference numbers for easy identification.
Key Features And Function
The pyrotechnic pretensioner is an integral part of the seatbelt restraint system. In the event of a significant impact it actuates a small pyrotechnic charge that retracts slack from the belt webbing within milliseconds, improving occupant positioning before the airbag deploys. It is not a reusable item after deployment.
Fitment And Compatibility
- Citroën C4 I (5-door)
- Peugeot 307 (compatible with corresponding body variants)
Replacement And Installation
Intended for installation by trained technicians or experienced DIYers familiar with SRS systems. Basic replacement steps:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow the SRS capacitors to discharge.
- Remove interior trim panels and seat as required to access the pretensioner anchorage.
- Unbolt the old assembly, carefully disconnect the electrical connector, and remove.
- Fit the new assembly, reconnect the electrical plug, and secure all fasteners to the vehicle manufacturer’s torque specifications.
- Reconnect the battery and clear SRS codes with a diagnostic tool; verify the airbag warning lamp is extinguished.
Failure Modes And Maintenance
Pretensioners typically require replacement if they have deployed during a collision. Other failure causes include corrosion, water ingress, damaged wiring or connectors, and exposure to severe mechanical damage. Regular inspection after accidents or when an airbag warning is present is essential. Do not attempt to repair a deployed or damaged pretensioner.
