Front Air Bag Operation
Front Air Bags are designed to provide additional
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 indicators 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 Occupant Restraint Controller (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
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.
Occupant Classification System (OCS) —
Front Passenger Seat
The Occupant Classification System (OCS) is part
of a Federally regulated safety system for this
vehicle. It is designed to provide Passenger
Advanced Front Air Bag output appropriate to the
occupant’s seated weight, as determined by the
OCS.The Occupant Classification System (OCS) consists
of the following:
Occupant Restraint Controller (ORC)
Occupant Classification Module (OCM) and
Sensor located in the front passenger seat
Air Bag Warning Light
Occupant Classification Module (OCM) And
Sensor
The Occupant Classification Module (OCM) is
located underneath the front passenger seat. The
Sensor is located beneath the passenger seat
cushion foam. Any weight on the seat will be
sensed by the Sensor. The OCM uses input from
the Sensor to determine the front passenger’s
most probable classification. The OCM
communicates this information to the ORC. The
ORC may reduce the inflation rate of the Passenger
Advanced Front Air Bag deployment based on
occupant classification. In order for the OCS to
operate as designed, it is important for the front
passenger to be seated properly and properly
wearing the seat belt.

(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.

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 appro -
priate) 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, occu -
pants 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 MAINTENANCE365
Consult an authorized tire dealer for tire repairs
and additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical
size and service description (Load Index and
Speed Symbol). Replace the tire pressure sensor
as well as it is not designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation pressure is
of/or below 14 psi (96 kPa). Once a Run Flat tire
reaches the Run Flat mode it has limited driving
capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable. When a Run Flat
tire is changed after driving with an underinflated
tire condition, please replace the TPMS sensor as
it is not designed to be reused when driven under
run flat mode 14 psi (96 kPa) condition.
NOTE:TPMS Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
run flat mode Ú page 247.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions,
do not spin your vehicle's wheels above 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping.
Tread Wear Indicators
Tread wear indicators are in the original equipment
tires to help you in determining when your tires
should be replaced.

Tire Tread

These indicators are molded into the bottom of the
tread grooves. They will appear as bands when the
tread depth becomes a 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced
Ú page 366.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

366SERVICING AND MAINTENANCE
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation pres -
sures can cause uneven wear patterns to
develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement.
Distance driven.
Performance tires, tires with a speed rating of V
or higher, and Summer tires typically have a
reduced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended.
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 Ú
page 365. 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 357.
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.
WARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.
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.

WHEEL AND WHEEL TRIM CARE
All wheels and wheel trim, especially aluminum
and chrome plated wheels, should be cleaned
regularly using mild (neutral Ph) soap and water to
maintain their luster and to prevent corrosion.
Wash wheels with the same soap solution
recommended for the body of the vehicle and
remember to always wash when the surfaces are
not hot to the touch. Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other road
chemicals used to melt ice or control dust on dirt
roads. Use a soft cloth or sponge and mild soap to
wipe away promptly. Do not use harsh chemicals or
a stiff brush. They can damage the wheel’s
protective coating that helps keep them from
corroding and tarnishing.
When cleaning extremely dirty wheels including
excessive brake dust, care must be taken in the
selection of tire and wheel cleaning chemicals and
equipment to prevent damage to the wheels.
Mopar® Wheel Treatment or Mopar® Chrome
Cleaner or their equivalent is recommended or
select a non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
WARNING!
Limited use spares are for emergency use only.
Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive
more than the speed listed on the limited use
spare wheel. Keep inflated to the cold tire
inflation pressures listed on your Tire and
Loading Information Placard located on the
driver’s side B-pillar or the rear edge of the
driver’s side door. Replace (or repair) the original
equipment tire at the first opportunity and
reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
CAUTION!
Avoid products or automatic car washes that use
acidic solutions or strong alkaline additives or
harsh brushes. Many aftermarket wheel
cleaners and automatic car washes may
damage the wheel's protective finish. Such
damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap, Mopar®
Wheel Cleaner or equivalent is recommended.
