2014 JEEP GRAND CHEROKEE child seat

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.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) determines
whether the severity, or type of rear impact will require
the Active Head Restraints (AHR) to deploy. If a rear
impact requires deployment, both the driver and front
passenger seat AHRs will be deployed.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Always sit upright as possible with your back against the
seat back, use the seat belts properly, and use the
appropriate sized child restraint, infant restraint or
booster seat recommended for the size and weight of the
child.
SAB and SABIC air bags are a supplement to the seat belt
restraint system. Occupants, including children who
are up against or very close to SAB or SABIC air bags can
be seriously injured or killed. Occupants, especially
children, should not lean on or sleep against the door,
side windows, or area where the SAB or SABIC air bags
inflate, even if they are in an infant or child restraint.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bag.Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved protection for the driver and front passenger. Side
air bags also work with seat belts to improve occupant
protection.
The Supplemental Driver Side Knee Air Bag provides
enhanced protection and works together with the Driver
Advanced Front Air Bag during a frontal impact.

The ORC determines if a side collision requires the side
air bags to inflate, based on the severity and type of
collision.
Based on the severity and type of collision, the side air
bag inflator on the crash side of the vehicle may be
triggered, releasing a quantity of non-toxic gas. The
inflating SAB exits through the seat seam into the space
between the occupant and the door. The SAB fully inflate
in about 10 milliseconds. The side air bag moves at a very
high speed and with such a high force that it could injure
you if you are not seated properly, or if items are
positioned in the area where the side air bag inflates. This
especially applies to children.
Supplemental Driver Side Knee Air Bag Inflator
Unit
The Supplemental Driver Side Knee Air Bag unit is
located in the instrument panel trim beneath the steering
column. When the ORC detects a collision requiring theair bag, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Supplemental
Driver Side Knee Air Bag. The trim cover separates and
folds out of the way allowing the air bag to inflate to the
full size. The air bag fully inflates in about 15 to 20 milli-
seconds.
Supplemental Side Air Bag Inflatable Curtain
(SABIC) Inflator Units
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may
deploy the SABIC air bags, depending on the severity
and type of collision. In these events, the ORC will
deploy the SABIC only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to inflate the
SABIC. The inflating SABIC pushes the outside edge of
the headliner out of the way and covers the window. The
SABIC inflates in about 30 milliseconds (about one-
quarter of the time that it takes to blink your eyes) with
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:In a rollover the pretensioners and/or SAB and
SABIC air bags, and driver/passenger knee air bags may
deploy on both sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
• Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
• Unlock the doors automatically.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

personal data (e.g., name, gender, age, and crash loca-
tion) are recorded. However, other parties, such as law
enforcement, could combine the EDR data with the type
of personally identifying data routinely acquired during
a crash investigation.
To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed.
In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equip-
ment, can read the information if they have access to the
vehicle or the EDR.
Child Restraints
Everyone in your vehicle needs to be buckled up at all
times, including babies and children. Every state in the
United States, and every Canadian province, requires
that small children ride in proper restraint systems. This
is the law, and you can be prosecuted for ignoring it.Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
WARNING!
In a collision, an unrestrained child can become a
projectile inside the vehicle. The force required to
hold even an infant on your lap could become so
great that you could not hold the child, no matter
how strong you are. The child and others could be
badly injured. Any child riding in your vehicle
should be in a proper restraint for the child’s size.

There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner ’s Manual to make sure you have the correct
seat for your child. Carefully read and follow all the
instructions and warnings in the child restraint Owner ’s
Manual and on all the labels attached to the car seat.
Before buying any restraint system, make sure that it has
a label certifying that it meets all applicable Safety
Standards. You should also make sure that you can install
it in the vehicle where you will use it.NOTE:

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 87

Infants And Child Restraints
Safety experts recommend that children ride rearward-
facing in the vehicle until they are two years old or until
they reach either the height or weight limit of their rear
facing child safety seat. Two types of child restraints can
be used rearward-facing: infant carriers and convertible
child seats.
The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children from birth until
they reach the weight or height limit of the infant carrier.
Convertible child seats can be used either rearward-
facing or forward-facing in the vehicle. Convertible child
seats often have a higher weight limit in the rearward-
facing direction than infant carriers do, so they can be
used rearward-facing by children who have outgrowntheir infant carrier but are still less than at least two years
old. Children should remain rearward-facing until they
reach the highest weight or height allowed by their
convertible child seat.
WARNING!
•
Never place a rear facing infant seat in front of
an air bag. A deploying Passenger Advanced Front
Air Bag can cause death or serious injury to a child
12 years or younger, including a child in a rearward
facing infant seat.
• Only use a rearward-facing child restraint in a
vehicle with a rear seat.
