2017 JEEP GRAND CHEROKEE flat tire

WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the engine control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
– Electronic Stability Control (ESC)
Warning Light
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition switch
is turned to the ON/RUN position. It should
go out when the engine is running. If the “ESC Indicator Light” comes on continuously
with the engine running, a malfunction has
been detected in the ESC system. If this light
remains on after several ignition cycles, and
the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
• The “ESC Off Indicator Light” and the
“ESC Indicator Light” come on momen-
tarily each time the ignition switch is
turned to ON/RUN.
• Each time the ignition is turned to ON/ RUN, the ESC system will be ON, even if it
was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
This telltale indicates that an ESC event is
active.
– Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
– Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel con-
sumption may not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in se-
quence.
IMPORTANT: Do not continue driving with one
or more flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp brak-
ing and steering. Repair immediately using
the dedicated tire repair kit and contact your
authorized dealer as soon as possible.
GETTING TO KNOW YOUR INSTRUMENT PANEL

Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tiresor wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealer to have your sensor
function checked.

ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
• Oversteer - when the vehicle is turningmore than appropriate for the steering
wheel position.
• Understeer - when the vehicle is turning less than appropriate for the steering
wheel position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.WARNING!
• Electronic Stability Control (ESC) can- not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents re-
sulting from loss of vehicle control due
to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skill-
ful driver can prevent accidents. The
capabilities of an ESC equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopar-
dize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
WARNING!
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.
ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating modes.
ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode

Tire Pressure Monitor System (TPMS)
NOTE:
For vehicles equipped with run flat tires —
When the TPMS indicates a tire pressure of
14 psi (96 kPa) or lower, always check tire
pressure and replace the tire at the first
opportunity. At inflation pressure of/or below
14 psi (96 kPa) the tire is in the run-flat
mode of operation. In this condition, it is
recommended a vehicle maximum speed of
50 mph (80 km/h) for a maximum distance of
50 miles (80 km). The manufacturer does not
recommend using the run flat feature while
driving a vehicle loaded at full capacity or
towing a trailer.
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure
based on the vehicle recommended cold tire
pressure.
The tire pressure will vary with temperature
by about 1 psi (7 kPa) for every 12°F (6.5°C).
This means that when the outside tempera-
ture decreases, the tire pressure will de-
crease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehiclehas not been driven for at least three hours, or
driven less than 1 mile (1.6 km) after a
three-hour period.
Refer to “Tires” in “Servic-
ing And Maintenance” for information on how to
properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is
driven - this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low pressure warning threshold for any rea-
son, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of
low tire pressure as long as the condition
exists, and will not turn off until the tire
pressure is at or above recommended cold
tire pressure. Once the low tire pressure
warning has been illuminated, the tire pres-
sure must be increased to the recommended
cold tire pressure in order for the Tire Pres-
sure Monitoring Telltale Light to be turned
off. 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 and the
Tire Pressure Monitoring Telltale Light will
extinguish once the updated tire pressures
have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
For example, your vehicle has a recom-
mended cold (parked for more than three
hours) tire pressure of 33 psi (227 kPa). If
the ambient temperature is 68°F (20°C) and
the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C)
will decrease the tire pressure to approxi-
mately 24 psi (165 kPa). This tire pressure is
sufficiently low enough to turn ON the Tire
Pressure Monitoring Telltale Light. Driving
the vehicle may cause the tire pressure to rise
to approximately 28 psi (193 kPa), but the
Tire Pressure Monitoring Telltale Light will
still be ON. In this situation, the Tire Pressure
107

Monitoring Telltale Light will turn OFF only
after the tires have been inflated to the vehi-
cle’s recommended cold tire pressure value.
CAUTION!
• The TPMS has been optimized for theoriginal equipment tires and wheels.
TPMS pressures and warnings have
been established for the tire size
equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equip-
ment that is not of the same size, type,
and/or style. Aftermarket wheels can
cause sensor damage. Using aftermar-
ket tire sealants may cause the Tire Pres-
sure Monitoring System (TPMS) sensor
to become inoperable. After using an
aftermarket tire sealant it is recom-
mended that you take your vehicle to an
authorized dealership to have your sen-
sor function checked.
• After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
CAUTION!
could damage the Tire Pressure Monitor-
ing Sensor.
NOTE:
• The TPMS is not intended to replace nor- mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• The TPMS should not be used as a tire pressure gauge while adjusting your tire
pressure.
• Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure using an accurate tire gauge, even if
under-inflation has not reached the level
to trigger illumination of the Tire Pressure
Monitoring Telltale Light. • Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Premium System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.

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

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

Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, engine coolant, oil, or other
fluid leaks. Also, if gasoline fumes are de-
tected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are sus-
pected. The cause should be located and
corrected immediately.
