Seat Belt Pretensioner — If Equipped
The front passenger seat belt is equipped with a preten-
sioning device that is designed to remove any slack from
the seat belt systems in the event of a collision. These
devices improve the performance of the seat belt by
assuring that the belt is tight around the occupant early
in a collision. Pretensioners work for all size occupants,
including those in child restraints.
NOTE: These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioner is triggered by the Occupant Restraint
Controller (ORC). Like the airbags, the pretensioners are
single use items. After a collision that is severe enough to
deploy the airbags and pretensioners, both must be
replaced.
Supplemental Rear Impact Active Head Restraints
(AHR)
These head restraints are passive, deployable compo-
nents, and vehicles with this equipment can not be
readily identified by any markings, only through visual
inspection of the head restraint. The head restraint will be
split in two halves, with the front half being soft foam
and trim, the back half being decorative plastic.
How the Active Head Restraints (AHR) work
The Occupant Restraint Controller (ORC) determines
whether the severity or type of rear impact require the
Active Head Restraints (AHR) to deploy. In case of AHR
deployment both driver and passenger seat AHR’s will
be deployed.
