SAFETY237
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.
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
SERVICE TPMS WARNING
When 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 TPM 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.
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.

(Continued)
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.
This vehicle is equipped with a right front
passenger Occupant Classification System (OCS)
that is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s
seated weight input, as determined by the OCS.
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.
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 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.
WARNING!

IN CASE OF EMERGENCY291
6. Install the inflatable spare on the vehicle, located in the rear cargo area of the vehicle.

Mounting Inflatable Spare Tire

NOTE:Do not install the wheel cover on the inflatable
spare tire.
7. Leave the vehicle on the jack and start inflating the inflatable spare after the tire has
been mounted to the vehicle. Secure the
wheel to the hub by tightening the nuts with
the wrench. After inflation, once the vehicle is
lowered you will have a second opportunity to
torque the lug nuts Ú page 360.
8. Inflate the tire to the prescribed pressure 60 psi (4.2 Bar) using the Portable Air
Compressor Ú page 293 or Tire Service Kit if
equipped Ú page 294.
9. Lower the vehicle once the inflatable Spare has reached its pressure and the
compressor-hose has been removed from the
tire valve. 10. Finish tightening the lug nuts. Push down on
the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice Ú page 360. If in doubt about the
correct tightness, have them checked with a
torque wrench by an authorized dealer or at a
service station.
11. Lower the jack to its fully-closed position.
12. Place the deflated (flat) tire and foam tray cover assembly in the rear cargo area. Do not
stow the deflated tire in the inflatable spare
tire location. Have the full-sized tire repaired or
replaced, as soon as possible.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until the
vehicle has been lowered. Failure to follow this
warning may result in serious injury.
CAUTION!
Be sure to mount the inflatable spare tire with
the valve stem facing outward. The vehicle could
be damaged if the inflatable spare tire is
mounted incorrectly.
WARNING!
A loose tire or jack thrown forward in a collision
or hard stop could endanger the occupants of
the vehicle. Always stow the jack parts and the
spare tire in the places provided. Have the
deflated (flat) tire repaired or replaced
immediately.

348SERVICING AND MAINTENANCE
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 236.
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 349.
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.1 — Worn Tire

SERVICING AND MAINTENANCE349
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 348. 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 340.
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.
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 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.

22_RUP_OM_EN_USC_t.book Page 352

SERVICING AND MAINTENANCE353
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.
NOTE:If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the
brakes to remove the water droplets from the
brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle
vibration when braking.
