Energy Management Feature; Seat Belt Pretensioners; Supplemental Active Head Restraints (Ahr) - Chrysler 2014 Grand Cherokee SRT Owner's Manual

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 collision.
This safety belt system has a retractor assem-
bly that is designed to release webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the occu-
pant's chest.

Seat Belt Pretensioners

The seat belts for both front seating positions are
equipped with pretensioning devices that are de-
signed 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.

PAGE POSITION: 38
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners 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
components, and vehicles with this equipment
cannot be readily identified by any markings,
only through visual inspection of the head re-
straint. 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) de-
termines whether the severity, or type of rear
impact will require the Active Head Restraints
JOB: @zeta.tweddle.com/InfoShareAuthoroChrysler/CLS_InfoShareAuthoroChrysler/GRP_Owners_Manual/JOB_
(AHR) to deploy. If a rear impact requires de-
ployment, both the driver and front passenger
seat AHRs will be deployed.
When AHRs deploy during a rear impact, the
front half of the head restraint extends forward
to minimize the gap between the back of the
occupant's head and the AHR. This system is
designed to help prevent or reduce the extent of
injuries to the driver and front passenger in
certain types of rear impacts.
NOTE:
The Active Head Restraints (AHR) may or may
not deploy in the event of a front or side
impact. However if during a front impact, a
secondary rear impact occurs, the AHR may
deploy based on the severity and type of the
impact.
