TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard 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 temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
The tire pressure will also increase as the vehicle
is driven — this is normal and there should be no
adjustment for this increased pressure.
See Ú page 279 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure
warning limit for any reason, including low
temperature effects and 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
the recommended cold placard pressure. Once the
low tire pressure warning (TPMS Warning Light)
illuminates, you must increase the tire pressure to
the recommended cold placard pressure in order
for the TPMS Warning Light to turn off. The system
will automatically update and the TPMS Warning
Light will turn off once the system receives the
updated tire pressures. 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
information.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the TPMS Warning Light off.
For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20°F (-7°C) will decrease the
tire pressure to approximately 23 psi (158 kPa).
This tire pressure is sufficiently low enough to turn
on the TPMS Warning Light. Driving the vehicle
may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires
are inflated to the vehicle’s recommended cold
placard pressure value Ú
page 311.
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 operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. The TPMS
sensor is not designed for use on aftermarket
wheels and may contribute to a poor overall
system performance or sensor damage.
Customers are encouraged to use OEM wheels
to ensure proper TPMS feature operation.

Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor 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 could damage the TPMS sensor.

190SAFETY
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure, unless
your vehicle is equipped with a Tire Fill Alert
(TFA) system.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency 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 pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning 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 Monitoring 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 check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate
in the instrument cluster and a chime
will sound when tire pressure is low in
one or more of the four active road tires.
In addition, the instrument cluster will display an
“Inflate to XX” message and a graphic showing the
pressure values of each tire with the low tire
pressure values shown in a different color.

Tire Pressure Monitoring System Display

21_LA_OM_EN_USC_t.book Page 190

SAFETY191
Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those shown in a different color in the
instrument cluster graphic) to the vehicle’s
recommended cold placard pressure inflation
value as shown in the “Inflate to XX” message.
Once the system receives the updated tire
pressures, the system will automatically update,
the graphic display in the instrument cluster will
change color back to the original color, and the
TPMS Warning Light will turn off. 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 information.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the TPMS Warning Light off.

Low Tire Pressure Monitoring System Display

Service Tire Pressure Monitoring System
Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a chime. In
addition, the instrument cluster will display a
"Service Tire Pressure System" message for a
minimum of five seconds and then display dashes
(- -) in place of the pressure value to indicate which
sensor 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 TPMS Warning
Light will no longer flash, and the "Service Tire
Pressure System" message will no longer display,
and a pressure value will display in place of the
dashes. A system fault can occur due to any of the
following:
Signal interference due to electronic devices or
driving next to facilities emitting the same radio
frequencies as the TPMS sensors
Accumulation of snow or ice around the wheels
or wheel housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors Vehicles With Compact Spare


1. The compact spare tire or non-matching full size does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact or
non-matching full size spare tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key cycle, the TPMS
Warning Light will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a different
color pressure value and an "Inflate to XX"
message.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the
instrument cluster will display a “Service Tire
Pressure System” message for five seconds
and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster will
display a “Service Tire Pressure System”
message for five seconds and then display
dashes (- -) in place of the pressure value.

5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the
compact spare or non-matching full size, the
TPMS will update automatically. In addition,
the TPMS Warning Light will turn off and the
graphic in the instrument cluster 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
information.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (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 Monitoring System
(TPMS) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “Service Tire
Pressure 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 Tire
Pressure 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
TPMS sensors. Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then turn off. The
instrument cluster will display the “Service Tire
Pressure System” message and then display
pressure values in place of the dashes. On the next
ignition cycle the "Service Tire Pressure System"
message will no longer be displayed as long as no
system fault exists.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints 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 an authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air bag:

1. Children 12 years old and under should
always ride buckled up in the rear seat of a
vehicle with a rear seat.

If your vehicle is not equipped with a rear
seat, FCA US LLC recommends that you do
not allow children 12 years old and under to
ride in your vehicle.
2. A child who is not big enough to wear the vehicle seat belt properly must be secured in
the appropriate child restraint or
belt-positioning booster seat in a rear seating
position Ú page 208.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 208.

21_LA_OM_EN_USC_t.book Page 192

SAFETY225
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE 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
lug nuts/bolt torque 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 locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift
-
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:

Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless gas,
which can kill. Never run the engine in a closed
area, such as a garage, and never sit in a parked
vehicle with the engine running for an extended
period. If the vehicle is stopped in an open area
with the engine running for more than a short
period, adjust the ventilation system to force
fresh, outside air into the vehicle.

Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.

TIRE SERVICE KIT USAGE PRECAUTIONS
Replace the Tire Service Kit Sealant Bottle (1)
and Sealant Hose (4) prior to the expiration date
(printed at the upper left hand corner on the
bottle label) to assure optimum operation of the
system Ú page 238.

Tire Service Kit Expiration Date Location

The Sealant Bottle (1) and Sealant Hose (4) are
a one tire application use and need to be
replaced after each use. Always replace these
components immediately at your original equip -
ment vehicle dealer.
When the Tire Service Kit sealant is in a liquid
form, clean water and a damp cloth will remove
the material from the vehicle or tire and wheel
components. Once the sealant dries, it can
easily be peeled off and properly discarded.
For optimum performance, make sure the valve
stem on the wheel is free of debris before
connecting the Tire Service Kit.
You can use the Tire Service Kit air pump to
inflate bicycle tires. The kit also comes with two
needles, located in the Accessory Storage
Compartment (on the bottom of the air pump)
for inflating sport balls, rafts, or similar inflat -
able items. However, use only the Air Pump
Hose (8) and make sure the Mode Select Knob
(6) is in the Air Mode when inflating such items
to avoid injecting sealant into them. The Tire
Service Kit Sealant is only intended to seal
punctures less than 1/4 inch (6 mm) diameter
in the tread of your tire.
Do not lift or carry the Tire Service Kit by the
hoses.
WARNING!
Do not attempt to seal a tire on the side of the
vehicle closest to traffic. Pull far enough off
the road to avoid the danger of being hit when
using the Tire Service Kit.
Do not use Tire Service Kit or drive the vehicle
under the following circumstances:
If the puncture in the tire tread is approxi -
mately 1/4 inch (6 mm) or larger.
If the tire has any sidewall damage.
If the tire has any damage from driving
with extremely low tire pressure.
If the tire has any damage from driving on
a flat tire.
If the wheel has any damage.
If you are unsure of the condition of the
tire or the wheel.
Keep Tire Service Kit away from open flames
or heat source.
A loose Tire Service Kit thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the Tire
Service Kit in the place provided. Failure to
follow these warnings can result in injuries
that are serious or fatal to you, your passen -
gers, and others around you.

IN CASE OF EMERGENCY237
(Continued)
3. The Sealant Bottle (1) may be empty due to
previous use. Call for assistance.
NOTE:If the Mode Select Knob (6) is on Air Mode and the
pump is operating, air will dispense from the Air
Pump Hose (8) only, not the Sealant Hose (4).
If the sealant (white fluid) does flow through the
Sealant Hose :

1. Continue to operate the pump until sealant is no longer flowing through the hose (typically takes
30 - 70 seconds). As the sealant flows through
the Sealant Hose (4), the Pressure Gauge (5)
can read as high as 70 psi (4.8 Bar). The
Pressure Gauge (5) will decrease quickly from
approximately 70 psi (4.8 Bar) to the actual tire
pressure when the Sealant Bottle (1) is empty.

2. The pump will start to inject air into the tire immediately after the Sealant Bottle (1) is
empty. Continue to operate the pump and
inflate the tire to the pressure indicated on the
tire pressure label on the driver-side latch
pillar (recommended pressure). Check the tire
pressure by looking at the Pressure Gauge (5). If the tire does not inflate to at least 26 psi
(1.8 Bar) pressure within 15 minutes:
The tire is too badly damaged. Do not attempt to
drive the vehicle further. Call for assistance.
NOTE:If the tire becomes overinflated, push the Deflation
Button (2) to reduce the tire pressure to the recom
-
mended inflation pressure before continuing.
If the tire inflates to the recommended pressure or
is at least 26 psi (1.8 Bar) pressure within
15 minutes:

1. Push the Power Button (3) to turn off the Tire Service Kit.

2. Remove the Speed Limit sticker from the top of the Sealant Bottle (1) and place the sticker on
the instrument panel.
3. Immediately disconnect the Sealant Hose (4) from the valve stem, reinstall the cap on the
fitting at the end of the hose, and place the Tire
Service Kit in the vehicle storage location.
(D) Drive Vehicle:
Immediately after injecting sealant and inflating
the tire, drive the vehicle 5 miles (8 km) or 10 minutes to ensure distribution of the Tire
Service Kit Sealant within the tire. Do not exceed
50 mph (80 km/h).
CAUTION!

The metal end fitting from Power Plug (7) may
get hot after use, so it should be handled
carefully.

Failure to reinstall the cap on the fitting at the
end of the Sealant Hose (4) can result in
sealant contacting your skin, clothing, and the
vehicle’s interior. It can also result in sealant
contacting internal Tire Service Kit compo -
nents which may cause permanent damage to
the kit.
WARNING!

Tire Service Kit is not a permanent flat tire
repair. Have the tire inspected and repaired or
replaced after using Tire Service Kit. Do not
exceed 50 mph (80 km/h) until the tire is
repaired or replaced. Failure to follow this
warning can result in injuries that are serious or
fatal to you, your passengers, and others
around you.
