A SuperCab vehicle with seat integrated restraints (SIR) is equipped with safety belt buckle pretensioners. These are for the front outboard occupants, located on the inboard side of the seats. To identify a SIR seat, refer to Seat Integrated Restraints (SIR) Identification.
The safety belt buckle pretensioner is a pyrotechnic device that removes excess webbing from the safety belt system. When the front air bag system is deployed, the pretensioner in the buckle deploys, causing the buckle to move downward, pulling excess webbing from the lap and shoulder safety belts
