SAFETY BELT PRETENSIONERS
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 an
impact event exceeding a programmed limit and the safety belt is latched (connected).
