2017 JEEP GRAND CHEROKEE wheel

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
110

for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the "TPM Telltale Light"
will flash on and off for 75 seconds and then
remain on. The instrument cluster will dis-
play the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the
pressure values.
Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires) with
tires equipped with TPM sensors. Then, drive
the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the
"TPM Telltale Light" will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TPM SYS-
TEM” message and then display pressure
values in place of the dashes. On the next
ignition cycle the "SERVICE TPM SYSTEM"
message will no longer be displayed as long
as no system fault exists.General Information

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.

122

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
protective covers for the air bag cushions

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:

Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bagsystem 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 in-
strument panel. Do not modify the front
bumper, vehicle body structure, or add
aftermarket side steps or running
boards.
WARNING!
• It is dangerous to try to repair any part ofthe air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to your authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
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 sys-
tems 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 un- derstanding of the circumstances in which
crashes and injuries occur.
