the Transmission Temperature Warning Light
is illuminated you could cause the fluid to boil
over, come in contact with hot engine or
exhaust components and cause a fire.
Engine Oil Change Indicator System
Oil Change Due — Gasoline Engine
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change Due”
message will flash in the EVIC display for
approximately 10 seconds after a single chime
has sounded, to indicate the next scheduled oil
change interval. The engine oil change indicator
system is duty cycle based, which means the
engine oil change interval may fluctuate, depen-
dent upon your personal driving style.
Unless reset, this message will continue to
display each time you turn the ignition switch to
the ON/RUN position or cycle the ignition to the
ON/RUN position if equipped with Keyless

Average Fuel Economy / Fuel Saver
Mode — If Equipped
Shows the average fuel economy since the last
reset. When the fuel economy is reset, the
display will read “RESET” or show dashes for
two seconds. Then, the history information will
be erased, and the averaging will continue from
the last fuel average reading before the reset.
The ECO message will display above the average
fuel economy in the EVIC display. This message
will appear whenever the Multi-Displacement
System (MDS) (if equipped) allows the engine to
operate on four cylinders, or if you are driving in a
fuel efficient manner.
This feature allows you to monitor when you are
driving in a fuel efficient manner, and it can be
used to modify driving habits in order to in-
crease fuel economy.

Life Of TireThe service life of a tire is dependent upon
varying factors including, but not limited to:
•Driving style
• Tire pressure
• 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 maintenance schedule is
highly recommended.
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 seri-
ous injury or death.
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 TiresThe tires on your new vehicle provide a balance
of many characteristics. They should be in-
spected regularly for wear and correct cold tire
inflation pressure. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph
on “Tread Wear Indicators”. Refer to the “Tire
and Loading Information” placard 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.
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 origi-
nal wheels. It is recommended you contact your authorized
tire or original equipment vehicle dealer with
any questions you may have on tire specifica-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size or rating other
than that specified for your vehicle. Some
combinations of unapproved tires and
wheels may change suspension dimen-
sions and performance characteristics, re-
sulting in changes to steering, handling,
and braking of your vehicle. This can
cause unpredictable 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.

CAUTION!(Continued)
•Observe the traction device manufactur-
er’s instructions on the method of installa-
tion, operating speed, and conditions for
use. Always use the suggested operating
speed of the device manufacturer’s if it is
less than 30 mph (48 km/h).
• Do not use traction devices on a compact
spare tire.
TIRE ROTATION
RECOMMENDATIONS
Non-Directional Tires OnlyTires on the front and rear axles of vehicles
operate at different loads and perform different
steering, handling, and braking functions. For
these reasons, they wear at unequal rates. These effects can be reduced by timely rotation
of tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such
as those on On/Off-Road type tires. Rotation
will increase tread life, help to maintain mud,
snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Refer to the “Maintenance Schedule” for the
proper maintenance intervals. More frequent
rotation is permissible if desired. The reasons
for any rapid or unusual wear should be cor-
rected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System
will automatically locate the pressure values
displayed in the correct vehicle position
following a tire rotation.
The suggested rotation method is the “forward-
cross” shown in the following diagram.
TIRE PRESSURE MONITOR
SYSTEM (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold tire 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.

NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options, or au-
thorized dealer-installed options, must be
considered as part of the total load on your
vehicle. Refer to the tire loading information
placard located on the drivers door pillar for
the maximum combined weight of occu-
pants and cargo for your vehicle.
Towing RequirementsTo promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
CAUTION!
•Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
(Continued)
CAUTION!(Continued)
•Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
Perform the maintenance listed in the “Mainte-
nance Schedule.” Refer to “Maintenance Sched-
ule” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
WARNING!
Improper towing can lead to a collision. Fol-
low these guidelines to make your trailer
towing as safe as possible:
•Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be

WARNING!(Continued)
difficult for the driver to control. You could
lose control of your vehicle and have a
collision.
• When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the hook retainers of the
vehicle hitch. Cross the chains under the
trailer tongue and allow enough slack for
turning corners.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include an adaptive
drive strategy to avoid frequent shifting when
towing. However, if frequent shifting does occur
while in DRIVE, select TOW mode, or use the
AutoStick® shift control to select a lower gear.
NOTE:
Using TOW mode or selecting a lower gear
while operating the vehicle under heavy load-
ing conditions, will improve performance and
extend transmission life by reducing exces-
sive shifting and heat buildup. This action will
also provide better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then change
the transmission fluid and filter(s) as specified for
"police, taxi, fleet, or frequent trailer towing. Refer
to the “Maintenance Schedule” for the proper
maintenance intervals.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experi-
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
• Use speed control in flat terrain and with light
loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the
transmission into NEUTRAL and increase en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

ONBOARD DIAGNOSTIC
SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This
system monitors the performance of the emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light (MIL).” It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•
Prolonged driving with the MIL on could
cause further damage to the emission con-
trol system. It could also affect fuel economy
and drivability. The vehicle must be serviced
before any emissions tests can be per-
formed.
•If the MIL is flashing, while the engine is
running, severe catalytic converter dam-
age and power loss will soon occur. Imme-
diate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system de-
termines that the fuel filler cap is
loose, improperly installed, or dam-
aged, a loose gascap indicator will
display in the EVIC telltale display
area. Refer to “Electronic Vehicle
Information Center (EVIC) in “Understanding
Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and press the SELECT button to turn off the message. If the
problem continues, the message will appear the
next time the vehicle is started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the Malfunction
Indicator Light (MIL).
REPLACEMENT PARTS
Use of genuine MOPAR® parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR® parts for maintenance and
repairs will not be covered by the manufactur-
er’s warranty.
