JEEP GRAND CHEROKEE 2017 WK2 / 4.G User Guide

How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulderbelt.
2. Grasp the shoulder portion and pull down- ward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen-
gage the Automatic Locking Mode and acti-
vate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced if the switchable Automatic Locking Re-
tractor (ALR) feature or any other seat
belt function is not working properly
when checked according to the proce-
dures in the Service Manual.
WARNING!
• Failure to replace the seat belt assemblycould increase the risk of injury in colli-
sions.
• Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or forward-
facing child restraints that have a har-
ness for restraining the child.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable
components, and vehicles with this equip-
ment cannot be readily identified by any
markings, only through visual inspection 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 deco-
rative 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 Re- straints (AHR) to deploy. If a rear impact
requires deployment, 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 for-
ward to minimize the gap between the back of
the occupant’s head and the AHR. This sys-
tem is designed to help prevent or reduce the
extent of injuries to the driver and front pas-
senger 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.

Active Head Restraint (AHR) Components:WARNING!
• All occupants, including the driver,should not operate a vehicle or sit in a
vehicle’s seat until the head restraints
are placed in their proper positions in
order to minimize the risk of neck injury
in the event of a collision.
• Do not place items over the top of the
Active Head Restraint, such as coats,
seat covers or portable DVD players.
These items may interfere with the op-
eration of the Active Head Restraint in
the event of a collision and could result
in serious injury or death.
• Active Head Restraints may be deployed
if they are struck by an object such as a
hand, foot or loose cargo. To avoid acci-
dental deployment of the Active Head
Restraint ensure that all cargo is se-
cured, as loose cargo could contact the
Active Head Restraint during sudden
stops. Failure to follow this warning
could cause personal injury if the Active
Head Restraint is deployed. NOTE:
For more information on properly adjusting
and positioning the head restraint, refer to
“Adjusting Active Head Restraints” in “Get-
ting To Know Your Vehicle.”
Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered dur-
ing a collision, the front half of the head re-
straint will be extended forward and separated
from the rear half of the head restraint (See
Image). Do not drive your vehicle after the AHRs
have deployed. The head restraint must be reset
into the original position to best protect the
occupant for all types of collisions. An autho-
rized FCA US LLC dealer must reset the AHRs
on the driver’s and front passenger’s seat before
driving. Personally attempting to reset the AHRs
may result in damage to the AHRs that could
impair their function.
WARNING!
Deployed AHRs are not able to best pro-
tect you in all types of collisions. Have
deployed AHRs reset by an authorized
dealer immediately.

Supplemental Restraint System (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask your autho-
rized dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors• Seat Belt Pretensioners
• Seat Belt Buckle Switch
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever 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 bag system
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 in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction 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 malfunction 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 in 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 inter- mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant 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.
121

WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system 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.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light
is detected, which could affect the Supple-
mental Restraint System (“SRS”), the Re-
dundant Air Bag Warning Light will illumi-
nate on the instrument panel. The
Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single
chime will sound to alert you that the Redun-
dant Air Bag Warning Light has come on and
a fault has been detected. If the Redundant
Air Bag Warning Light comes on intermit-
tently or remains on while driving have an
authorized dealer service the vehicle imme-
diately. For additional information regarding the Re-
dundant Air Bag Warning Light, refer to
“Warning/Indicator Lights and Messages” in
“Getting to Know Your Instrument Panel”
section of this manual.
Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple-
ment to the seat belt restraint systems. The
driver front air bag is mounted in the center
of the steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The words
“SRS AIRBAG” or “AIRBAG” are embossed
on the air bag covers.

WARNING!
• Being too close to the steering wheel orinstrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending

your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint
in front of an air bag. A deploying pas-
senger 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.
Driver and Passenger Front Air Bag Features
The Advanced Front Air Bag system has mul-
tistage driver and front passenger air bags.
This system provides output appropriate to
the severity and type of collision as deter-
mined by the Occupant Restraint Controller
(ORC), which may receive information from
the front impact sensors (if equipped) or
other system components.
The first stage inflator is triggered immedi-
ately during an impact that requires air bag
deployment. A low energy output is used in
less severe collisions. A higher energy output
is used for more severe collisions. This vehicle may be equipped with a driver
and/or front passenger seat belt buckle
switch that detects whether the driver or front
passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of
the Advanced Front Air Bags.
This vehicle may be equipped with driver
and/or front passenger seat track position
sensors that may adjust the inflation rate of
the Advanced Front Air Bags based upon seat
position.
WARNING!
• No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air
bag to inflate.
• Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The

are designed to open only when the air
bags are inflating.
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
air bags won’t deploy at all. Always wear
your seat belts even though you have air
bags.
Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type
and location of impact, front air bags may
deploy in crashes with little vehicle front-end
damage but that produce a severe initial
deceleration. Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indica-
tors of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help
keep you in position, away from an inflating
air bag.
When the ORC detects a collision requiring
the front air bags, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the front air bags.
The steering wheel hub trim cover and the
upper right side of the instrument panel
separate and fold out of the way as the air
bags inflate to their full size. The front air
bags fully inflate in less time than it takes to
blink your eyes. The front air bags then
quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
WARNING!
• Do not drill, cut, or tamper with the knee
impact bolsters in any way.
• Do not mount any accessories to the
knee impact bolsters such as alarm
lights, stereos, citizen band radios, etc.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instru-
ment panel below the steering column. The
Supplemental Driver Knee Air Bag provides
enhanced protection during a frontal impact
by working together with the seat belts, pre-
tensioners, and front air bags.
SAFETY
124

Supplemental Side Air Bags
Your vehicle is equipped with two types of
side air bags:
1.Supplemental Seat-Mounted Side Air Bags
(SABs): Located in the outboard side of the
front seats. The SABs are marked with a
“SRS AIRBAG” or “AIRBAG” label sewn into
the outboard side of the seats. The SABs may help to reduce the risk of
occupant injury during certain side im-
pacts and/or vehicle rollover events, in
addition to the injury reduction potential
provided by the seat belts and body struc-
ture.
When the SAB deploys, it opens the seam
on the outboard side of the seatback’s
trim cover. The inflating SAB deploys
through the seat seam into the space
between the occupant and the door. The
SAB moves at a very high speed and with
such a high force that it could injure
occupants if they are not seated properly,
or if items are positioned in the area
where the SAB inflates. Children are at an
even greater risk of injury from a deploy-
ing air bag.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air
Bags; the performance could be adversely
affected and/or objects could be pushed
into you, causing serious injury.2.
Supplemental Side Air Bag Inflatable Cur-
tains (SABICs): Located above the side win-
dows. The trim covering the SABICs is la-
beled “SRS AIRBAG” or “AIRBAG.”SABICs may help reduce the risk of head or
other injuries to front and rear seat outboard
occupants in certain side impacts and/or
vehicle rollover events, in addition to the
injury reduction potential provided by the
seat belts and body structure.
Front Supplemental Seat-Mounted Side Air Bag Label
Supplemental Side Air Bag Inflatable Cur-tain (SABIC) Label Location

The SABICs deploy downward, covering
the side windows. An inflating SABIC
pushes the outside edge of the trim out of
the way and covers the window. The
SABICs inflate with enough force to in-
jure occupants if they are not belted and
seated properly, or if items are positioned
in the area where the SABICs inflate.
Children are at an even greater risk of
injury from a deploying air bag.
WARNING!
•Do not stack luggage or other cargo up
high enough to block the deployment of
the SABICs. The trim covering above the
side windows where the SABIC and its
deployment path are located should re-
main free from any obstructions.
• In order for the SABICs to work as in-
tended, do not install any accessory
items in your vehicle which could alter
the roof. Do not add an aftermarket sun-
roof to your vehicle. Do not add roof
racks that require permanent attach-
ments (bolts or screws) for installation
on the vehicle roof. Do not drill into the
roof of the vehicle for any reason. The SABICs and SABs (Side Air Bags) are
designed to activate in certain side impacts
and certain rollover events. The Occupant
Restraint Controller (ORC) determines
whether the deployment of the Side Air Bags
in a particular side impact or rollover event is
appropriate, based on the severity and type of
collision. Vehicle damage by itself is not a
good indicator of whether or not Side Air Bags
should have deployed.
Side Air Bags are a supplement to the seat
belt restraint system. Side Air Bags deploy in
less time than it takes to blink your eyes.
WARNING!
• Occupants, including children, who are
up against or very close to SABICs can
be seriously injured or killed. Occu-
pants, including children, should never
lean on or sleep against the door, side
windows, or area where the side air bags
inflate, even if they are in an infant or
child restraint.
• Seat belts (and child restraints where
appropriate) are necessary for your pro-
WARNING!
tection in all collisions. They also help
keep you in position, away from an in-
flating SABIC. To get the best protection
from the SABICs, occupants must wear
their seat belts properly and sit upright
with their backs against the seats. Chil-
dren must be properly restrained in a
child restraint or booster seat that is
appropriate for the size of the child.
• Side Air Bags need room to inflate. Do
not lean against the door or window. Sit
upright in the center of the seat.
• Being too close to the Side Air Bags
during deployment could cause you to
be severely injured or killed.
• Relying on the Side Air Bags alone could
lead to more severe injuries in a colli-
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
SAFETY
126

NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.
Side Impacts
In side impacts, the side impact sensors aid
the ORC in determining the appropriate re-
sponse to impact events. The system is cali-
brated to deploy the Side Air Bags on the
impact side of the vehicle during impacts
that require Side Air Bag occupant protec-
tion. In side impacts, the Side Air Bags de-
ploy independently; a left side impact de-
ploys the left Side Air Bags only and a right
side impact deploys the right Side Air Bags
only.
The Side Air Bags will not deploy in all side
collisions, including some collisions at cer-
tain angles, or some side collisions that do
not impact the area of the passenger com-
partment. The Side Air Bags may deploy
during angled or offset frontal collisions
where the front air bags deploy.Rollover Events
Side Air Bags are designed to activate in
certain rollover events. The ORC determines
whether the deployment of the Side Air Bags
in a particular rollover event is appropriate,
based on the severity and type of collision.
Vehicle damage by itself is not a good indica-
tor of whether or not Side Air Bags should
have deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing system
determines if a rollover event may be in
progress and whether deployment is appro-
priate. In the event the vehicle experiences a
rollover or near rollover event, and deploy-
ment of the Side Air Bags is appropriate, the
rollover sensing system will also deploy the
seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu-
pants through side windows in certain roll-
over or side impact events.The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting wiring associated with electrical Air
Bag System Components listed below:

If A Deployment Occurs
The 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 air bag material may sometimes causeabrasions and/or skin reddening to the
occupants as the air bags deploy and un-
fold. 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 imme-
diately.
• As the air bags deflate, you may see some smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may ir- ritate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irrita-
tion, move to fresh air. If the irritation
continues, see your doctor. If these par-
ticles settle on your clothing, follow the
garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags
have deployed. 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 preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well. NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be taken to an authorized dealer
immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion 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 Sys-
tem perform the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the batteryhas power or until the hazard light button
is pressed. The hazard lights can be deac-
tivated by pressing the hazard light but-
ton.
• Turn on the interior lights, which remain on as long as the battery has power.
• Unlock the power door locks.
