2017 JEEP GRAND CHEROKEE warning light

NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your tires
and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS)
consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring SystemMessages, which display in the instrument
cluster, and a graphic displaying tire pres-
sures
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitor-
ing Telltale Light will illu-
minate in the instrument
cluster, and an audible
chime will be activated,
when one or more of the
four active road tire pressures are low. In
addition, the instrument cluster will display a
"Tire Low" message, an "Inflate to XXX" mes- sage and a graphic display of the pressure
value(s) with the low tire(s) displayed in a
different color. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instru-
ment Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, BAR or kPa.
Should a low tire condition occur on any of
the four active road tire(s), you should stop as
soon as possible, and inflate the low tire(s)
that is in a different color on the graphic
display to the vehicle’s recommended cold
tire pressure displayed in the "Inflate to XXX"
message.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off. The system will
automatically update, the graphic display of
the pressure value(s) will return to its original
color and the Tire Pressure Monitoring Tell-
tale Light will extinguish once the updated
tire pressure(s) have been received. The ve-
hicle may need to be driven for up to 20 min-
utes above 15 mph (24 km/h) to receive this
information.Service TPM System Warning
The Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds, and
remain on solid when a system fault is de-
tected. The system fault will also sound a
chime. The instrument cluster display will
display a “SERVICE TPM SYSTEM” message
for a minimum of five seconds. This message
Low Tire Pressure Monitor Display
109

is then followed by a graphic display, with “-
-“ in place of the pressure value(s), indicat-
ing which Tire Pressure Monitoring Sensor(s)
is not being received.
If the ignition switch is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists, the
Tire Pressure Monitoring Telltale Light will no
longer flash, the "SERVICE TPM SYSTEM"
message will not be present, and a pressure
value will be displayed instead of dashes. A
system fault can occur by any of the follow-
ing:
• Jamming due to electronic devices or driv-ing next to facilities emitting the same
Radio Frequencies as the TPM sensors.
• Installing some form of aftermarket win- dow tinting that affects radio wave signals.
• Lots of snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors. NOTE:
There is no tire pressure monitoring sensor in
the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the
spare tire in place of a road tire that has a
pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the
Tire Pressure Monitoring Telltale Light will
remain ON, a chime will sound, and the
instrument cluster display will still display a
pressure value in the different color graphic
display and an "Inflate to XXX kPa" message
will be displayed. After driving the vehicle for
up to 20 minutes above 15 mph (24 km/h),
the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then
remain on solid. In addition, the instrument
cluster display will display a “SERVICE TPM
SYSTEM" message for five seconds and then
display dashes (- -) in place of the pressure
value. For each subsequent ignition switch
cycle, a chime will sound, the Tire Pressure
Monitoring Telltale Light will flash on and off
for 75 seconds and then remain on solid, and
the instrument cluster display will display a
"SERVICE TPM SYSTEM" message for five
seconds and then display dashes (- -) in place of the pressure value. Once you repair or
replace the original road tire, and reinstall it
on the vehicle in place of the spare tire, the
TPMS will update automatically.
In addition, the Tire Pressure Monitoring Tell-
tale Light will turn OFF and the graphic in the
instrument cluster display will display a new
pressure value instead of dashes (- -), as long
as no tire pressure is below the low-pressure
warning limit in any of the four active road
tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this informa-
tion.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires)
with wheel and tire assemblies that do not
have TPMS Sensors, such as when installing
winter wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with
tires not equipped with Tire Pressure Moni-
toring (TPM) Sensors. Then, drive the vehicle
SAFETY

Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat
belts are buckled. The outboard front passen-
ger seat BeltAlert is not active when an out-
board front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or out-
board front seat passenger is unbuckled (if
equipped with outboard front passenger seat
BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard
front passenger seat is unoccupied). The
BeltAlert warning sequence starts by blinking
the Seat Belt Reminder Light and sounding
an intermittent chime. Once the BeltAlert
warning sequence has completed, the SeatBelt Reminder Light will remain on until the
seat belts are buckled. The BeltAlert warning
sequence may repeat based on vehicle speed
until the driver and occupied outboard front
seat passenger seat belts are buckled. The
driver should instruct all occupants to buckle
their seat belts.
Change Of Status
If the driver or outboard front seat passenger
(if equipped with outboard front passenger
seat BeltAlert) unbuckles their seat belt while
the vehicle is traveling, the BeltAlert warning
sequence will begin until the seat belts are
buckled again. The outboard front passenger
seat BeltAlert is not active when the outboard
front passenger seat is unoccupied. BeltAlert
may be triggered when an animal or other
items are placed on the outboard front pas-
senger seat or when the seat is folded flat (if
equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by
seat belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by
your authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.NOTE:
If BeltAlert has been deactivated and the
driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled the Seat Belt Re-
minder Light will turn on and remain on until
the driver and outboard front seat passenger
seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are
equipped with lap/shoulder belts.
The seat belt webbing retractor will lock only
during very sudden stops or collisions. This
feature allows the shoulder part of the seat
belt to move freely with you under normal
conditions. However, in a collision the seat
belt will lock and reduce your risk of striking
the inside of the vehicle or being thrown out
of the vehicle.
WARNING!
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to

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.

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!
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

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.
