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

SAFETY203
The steering wheel hub trim cover and the upper
passenger 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.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs)
are located in the outboard side of the front seats.
The SABs are marked with “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on the
outboard side of the seats.
The SABs may help to reduce the risk of occupant
injury during certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label
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 deploying air bag.
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.
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.

SAFETY205
(Continued)
NOTE:Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events. The
Occupant Restraint Controller (ORC) determines
whether deployment in a particular 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 and seat
belt pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners will
not deploy in all rollover events. The rollover
sensing system determines if a rollover event may
be in progress and whether deployment is
appropriate. In the event the vehicle experiences a
rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy
the side air bags and seat belt pretensioners on
both sides of the vehicle.
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through side
windows in certain rollover or side impact events.

Air Bag System Components

NOTE:Vehicles with front passenger seat deleted will not
be equipped with the Seat Belt Buckle Switch, Seat
Belt Pretensioner, Supplemental Seat Mounted
Side Airbag, and Seat Track Position Sensors for
the front passenger.
WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
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 protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection
from the Side Air Bags, occupants must wear their
seat belts properly and sit upright with their backs
against the seats. Children must be properly
restrained in a child restraint or booster seat that
is appropriate for the size of the child.

WARNING!
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 collision. 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.

SERVICING AND MAINTENANCE291
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed Úpage 290. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
See the Tire Sizing Chart example found in the “Tire
Safety Information” section of this manual for
more information relating to the Load Index and
Speed Symbol of a tire Ú page 279.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels. It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season tires.
All season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use all
season tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in
snow or on ice. If your vehicle is equipped with
Summer tires, be aware these tires are not
designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient
temperatures are less than 40°F (5°C) or if roads
are covered with ice or snow. For more
information, contact an authorized dealer.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre
-
dictable handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading and failure. You could lose control and
have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.

292SERVICING AND MAINTENANCE
Summer tires do not contain the all season
designation or mountain/snowflake symbol on the
tire sidewall. Use Summer tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Snow Tires
Some areas of the country require the use of snow
tires during the Winter. Snow tires can be identified
by a “mountain/snowflake” symbol on the tire
sidewall. If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow tires
only in sets of four; failure to do so may
adversely affect the safety and handling of your
vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over
75 mph (120 km/h). For speeds above 75 mph
(120 km/h) refer to original equipment or an authorized tire dealer for recommended safe
operating speeds, loading and cold tire inflation
pressures.
While studded tires improve performance on ice,
skid and traction capability on wet or dry surfaces
may be poorer than that of non-studded tires.
Some states prohibit studded tires; therefore, local
laws should be checked before using these tire
types.
SPARE TIRES — IF EQUIPPED
NOTE:For vehicles equipped with Tire Service Kit instead
of a spare tire, please refer to “Tire Service Kit” in
“In Case Of Emergency” for further information.
For restrictions when towing with a spare tire
designated for temporary emergency use
Ú
page 115.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the
original equipment tire and wheel found on the
front or rear axle of your vehicle. This spare tire
may be used in the tire rotation for your vehicle. If
your vehicle has this option, refer to an authorized
tire dealer for the recommended tire rotation
pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at the
spare tire description on the Tire and Loading
Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first
opportunity.
WARNING!
Do not use Summer tires in snow/ice conditions.
You could lose vehicle control, resulting in
severe injury or death. Driving too fast for
conditions also creates the possibility of loss of
vehicle control.
CAUTION!
Because of the reduced ground clearance, do
not take your vehicle through an automatic car
wash with a compact or limited use temporary
spare installed. Damage to the vehicle may
result.

21_LA_OM_EN_USC_t.book Page 292

SERVICING AND MAINTENANCE293
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at any
given time.
Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a collapsible spare by looking at the
spare tire description on the Tire and Loading
Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Collapsible spare tire description example: 165/
80-17 101P. Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first
opportunity.
Inflate collapsible tire only after the wheel is
properly installed to the vehicle. Inflate the
collapsible tire using the electric air pump before
lowering the vehicle.
Do not install a wheel cover or attempt to mount a
conventional tire on the collapsible spare wheel,
since the wheel is designed specifically for the
collapsible spare tire.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use
only. This tire may look like the originally equipped
tire on the front or rear axle of your vehicle, but it is
not. This spare tire may have limited tread life.
When the tread is worn to the tread wear
indicators, the temporary use full size spare tire
needs to be replaced. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by a label
located on the limited use spare wheel. This label
contains the driving limitations for this spare. This
tire may look like the original equipped tire on the
front or rear axle of your vehicle, but it is not.
Installation of this limited use spare tire affects
vehicle handling. Since it is not the same as your
original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
WARNING!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph (80 km/
h). Temporary use spares have limited tread life.
When the tread is worn to the tread wear
indicators, the temporary use spare tire needs to
be replaced. Be sure to follow the warnings,
which apply to your spare. Failure to do so could
result in spare tire failure and loss of vehicle
control.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is on the left front corner of the instrument
panel. The VIN is visible from outside of the vehicle
through the windshield.
Windshield VIN Location

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. There will be some loss of overall braking
effectiveness. This may be evident by increased
pedal travel during application, greater pedal force
required to slow or stop, and potential activation of
the Brake Warning Light.
In the event power assist is lost for any reason (for
example, repeated brake applications with the
engine off), the brakes will still function. The effort
required to brake the vehicle will be much greater
than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
