2015 JEEP GRAND CHEROKEE Owners Manual

System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition
OFF.
Air Bag Warning Light
The air bags must be ready to inflate for your protection
in a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first turned to
the ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
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 switch is
first turned to the ON/RUN position.
•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.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.

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.
(Continued)
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.

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 pushing the accelera-
tor 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 per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, 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 pros-
ecuted 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 83

There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult seat 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 instruc-
tions and warnings in the child restraint Owner ’s Manual
and on all the labels attached to the child restraint.
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:
•For additional information, refer to www.seatcheck.org or

Infants And Child Restraints
Safety experts recommend that children ride rear-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 restraint. Two types of child restraints can be used
rear-facing: infant carriers and convertible child seats.
The infant carrier is only used rear-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 rear-facing or
forward-facing in the vehicle. Convertible child seats
often have a higher weight limit in the rear-facing
direction than infant carriers do, so they can be used
rear-facing by children who have outgrown their infant
carrier but are still less than at least two years old.
Children should remain rear-facing until they reach the
highest weight or height allowed by their convertible
child seat.
WARNING!
•Never place a rear-facing child restraint 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 rear-
facing child restraint.
•Only use a rear-facing child restraint in a vehicle
with a rear seat.
Older Children And Child Restraints
Children who are two years old or who have outgrown
their rear-facing convertible child seat can ride forward-
facing in the vehicle. Forward-facing child seats and
convertible child seats used in the forward-facing direc-
tion are for children who are over two years old or who
have outgrown the rear-facing weight or height limit of
their rear-facing convertible child seat. Children should
