Pre-tensioner seat belt
(if equipped)
Your vehicle is equipped with driver's and
front passenger's pre-tensioner seat
belts. The purpose of the pre-tensioner is
to make sure that the seat belts fit tightly
against the occupant's body in certain
frontal collisions. The pre-tensioner seat
belts can be activated, where the frontal
collision is severe enough, together with
the air bags.
3 18
When the vehicle stops suddenly, or if
the occupant tries to lean forward too
quickly, the seat belt retractor will lock
into position. In certain frontal collisions,
the pre-tensioner will activate and pull
the seat belt into tighter contact against
the occupant's body.
If the system senses excessive seat belt
tension on the driver or passenger's seat
belt when the pre-tensioner activates, the
load limiter inside the pre-tensioner will
release some of the pressure on the
affected seat belt. (if equipped)
