JEEP GRAND CHEROKEE 2014 WK2 / 4.G SRT Manual Online

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

In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from IGN ON to IGN OFF.
If A Deployment Occurs
The Advanced Front Air Bags are designed to deflate
immediately after deployment.
NOTE:Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with
the air bag system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
• The nylon air bag material may sometimes cause
abrasions and/or skin reddening to the driver and
front passenger as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or those you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
However, if you haven’t healed significantly within a
few days, or if you have any blistering, see your doctor
immediately.
• As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate the
skin, eyes, nose, or throat. If you have skin or eye
irritation, rinse the area with cool water. For nose or
throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer’s in-
structions for cleaning.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 81

Do not drive your vehicle after the air bags have de-
ployed. If you are involved in another collision, the air
bags will not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the front seat belt retrac-
tor assemblies replaced by an authorized dealer im-
mediately. Also, have the Occupant Restraint Con-
troller (ORC) system serviced as well.
Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure, or
add aftermarket side steps or running boards.
• It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.

WARNING!(Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
air bag system service. If your seat, including your
trim cover and cushion, needs to be serviced in any
way (including removal or loosening/tightening of
seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved
seat accessories may be used. If it is necessary to
modify the air bag system for persons with dis-
abilities, contact your authorized dealer.
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free. If any of
the following occurs, have an authorized dealer service
the air bag system immediately.
• The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition is first
cycled to the ON/RUN.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 83

NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to “Fuses” in
“Maintaining Your Vehicle” for the proper air bag fuses.
See your authorized dealer if the fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
•
How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if
a non-trivial crash situation occurs; no data are recorded
by the EDR under normal driving conditions and no
84 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 85

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.
