Seat Belt Pretensioners - Jeep Automobile Owner's Manual

44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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.
WARNING!
• The belt and retractor assembly must be replaced
if the seat belt assembly "automatic locking re-
tractor" feature or any other seat belt function is
not working properly when checked according to
the procedures in the Service Manual.
• Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.

Seat Belt Pretensioners

The driver and front passenger seat belts are equipped
with a pretensioning device that is designed to remove
any slack from the seat belt systems in the event of a
collision. This device improves 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 pretensioners are triggered by the Occupant Re-
straint Control (ORC) Module. Like the front airbags, the
pretensioners are a single use item. After a collision that
is severe enough to deploy the airbags and pretensioners,
they must be replaced.
