Safety Belt Pretensioners
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
As part of the supplemental restraint system SRS, the safety belt buckles are equipped with pretensioners. The safety belt buckle pretensioners remove excess slack from the safety belt webbing. The pretensioners are activated by the restraints control module (RCM) when the module detects a frontal or side impact event exceeding a programmed limit and the safety belt is latched (buckled). The passenger safety belt pretensioner can deploy regardless of the presence of an occupant if the front outboard passenger safety belt is latched (buckled).
