During a significant deceleration event the initiator fires a small pyrotechnic charge that rapidly reels the belt webbing, removing slack and securing the occupant before full airbag deployment. Pretensioners are single‑use safety devices: once deployed they must be replaced. This unit is intended for the right front seat (passenger side) on compatible Citroën models listed below.
