When a pretensioner activates, smoke is released and a loud noise may be heard. This smoke is not harmful and does not indicate a fire. Care should be taken not to inhale it, as it may cause irritation and choking. Those with a history of a breathing condition should get fresh air promptly. After pretensioner activation, load limiters allow the seat belt to release webbing (if necessary) to reduce forces against the chest. is The supplemental air bag warning light used to indicate malfunctions in the pretensioner system.
