Safety Belt Buckle and Pretensioners
SAFETY BELT BUCKLE AND PRETENSIONERS
As part of the supplemental restraint system (SRS), the driver and passenger front seat safety belt buckles are equipped with pretensioners. The safety
belt buckle and pretensioners are attached to the seat tracks. The safety belt buckle and pretensioners remove excess slack from the safety belt webbing
and are activated by the restraints control module (RCM) when the module detects a collision event force exceeding a programmed limit. For
information or if a deployment has occurred, refer to the appropriate procedure in Air Bag Systems.
