Jeep Grand Cherokee 2012, Owner'S Manual, Page: 65 / 688

Energy Management Feature
This vehicle has a safety belt system with an Energy
Management feature in the front seating positions to help
further reduce the risk of injury in the event of a head-on
accident.
This safety belt system has a retractor assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.
Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of a collision.
These devices may improve the performance of the seat
belt by assuring that the belt is tight about the occupant
early in a collision. Pretensioners work for all size occu-
pants, including those in child restraints.
NOTE: These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC). Like the air bags, the preten-
sioners are single use items. A deployed pretensioner or
a deployed air bag must be replaced immediately.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable compo-
nents, and vehicles with this equipment cannot be readily
identified by any markings, only through visual inspec-
tion 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.
