The seat belt pre-tensioners only activate once, and then must be replaced. Failure to replace the pre-tensioners reduces the effectiveness of the Supplementary Restraint System (SRS) in the event of an accident. The risk of serious injury or death in the event of an accident is then increased. The seat belts and pre-tensioners must be checked and, if necessary, replaced by a retailer/authorised repairer after an impact.
The seat belt pre-tensioners activate in conjunction with the SRS to provide additional protection in the event of a severe frontal impact, not rear impact. The seat belt pre-tensioners automatically reduce any slack in a seat belt. As a result, forward movement of a front seat occupant or an outboard rear seat occupant is reduced.
The rear centre seat is not fitted with a seat belt pre-tensioner.
