Installation Instructions
What is the Buckle Pretensioner and how does it work?
In the event of side roll, the Buckle Pretensioner deploys at each static seating
position. The pretensioner retracts the cable and buckle removing slack from
the belt.
The buckle pretensioner is only effective when used with a seatbelt. ALWAYS
WEAR YOUR SEATBELT.
