Floor Mat Safety Information
Always use floor mats designed to fit the foot-
well of your vehicle. Use only floor mats that
leave the pedal area unobstructed and that are
firmly secured so that they cannot slip out of
position and interfere with the pedals or impair
safe operation of your vehicle in other ways.
WARNING!
Pedals that cannot move freely can cause
loss of vehicle control and increase the risk
of serious personal injury.
•
Always make sure that floor mats are prop-
erly attached to the floor mat fasteners.
•Never place or install floor mats or other
floor coverings in the vehicle that cannot
be properly secured to prevent them from
moving and interfering with the pedals or
the ability to control the vehicle.
(Continued)
WARNING!(Continued)
•Never put floor mats or other floor cover-
ings on top of already installed floor mats.
Additional floor mats and other coverings
will reduce the size of the pedal area and
interfere with the pedals.
• Check mounting of mats on a regular
basis. Always properly reinstall and secure
floor mats that have been removed for
cleaning.
• Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
• If required, mounting posts must be prop-
erly installed, if not equipped from the
factory.
Failure to properly follow floor mat installa-
tion or mounting can cause interference with
the brake pedal and accelerator pedal opera-
tion causing loss of control of the vehicle.
Periodic Safety Checks You Should
Make 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 wheel nuts 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 positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located and
corrected immediately.

CAUTION!
To prevent damage to the starter, wait 10 to
15 seconds before trying again.
After StartingThe idle speed is controlled automatically and it
will decrease as the engine warms up.
Normal Starting – Diesel EngineObserve the following when the engine is oper-
ating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Low Oil Pressure Light is off.
Cold Weather Precautions
Operation in ambient temperature below
32°F (0°C) may require special considerations.
The following chart suggests these options.
*No. 1 Ultra Low Sulfur Diesel Fuel (ULSD)
should only be used where extended arctic
conditions (-10°F/-23°C) exist.
223

NOTE:
•Use of Climatized ULSD Diesel Fuel or
Number 1 ULSD Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized ULSD Diesel Fuel is a blend of
Number 2 ULSD and Number 1 ULSD
Diesel Fuels, which reduces the tempera-
ture at which wax crystals form in fuel.
NOTE:
This engine requires the use of “Ultra Low
Sulfur Diesel Fuel.” Use of incorrect fuel
could result in exhaust system damage. Re-
fer to “Fuel Requirements – Diesel Engine”
in “Starting and Operating” for further infor-
mation.
Battery Blanket Usage
A battery loses 60% of its cranking power as the
battery temperature decreases to 0°F (-18°C).
For the same decrease in temperature, the en-
gine requires twice as much power to crank at the
same RPM. The use of battery blankets will
greatly increase starting capability at low tem-
peratures. Suitable battery blankets are available
from your authorized MOPAR® dealer.
Engine Starting Procedure
WARNING!
NEVER pour fuel or other flammable liquid
into the air inlet opening in an attempt to start
the vehicle. This could result in a flash fire
causing serious personal injury.
1. The shift lever must be in the NEUTRAL or
PARK position before you can start the engine.
2. With your foot on the brake pedal, press the
ENGINE START/STOP button.
3. Watch the “Wait To Start Light” in the instru-
ment cluster. Refer to “Instrument Cluster” in
“Understanding Your Instrument Panel” for fur-
ther information. It may glow for up to three
seconds, depending on engine temperature.
4. When the “Wait To Start Light” goes out, the
engine will automatically start.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving. This
allows oil to circulate and lubricate the turbo-
charger. Avoid prolonged idling in ambient temperatures
below 0°F (-18°C). Long periods of idling may
be harmful to your engine because combustion
chamber temperatures can drop so low that the
fuel may not burn completely. Incomplete com-
bustion allows carbon and varnish to form on
piston rings and injector nozzles. Also, the
unburned fuel can enter the crankcase, diluting
the oil and causing rapid wear to the engine.
Engine Warm Up
Avoid full throttle operation when the engine is
cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow the
oil pressure to stabilize as the engine warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
If temperatures are below 32°F (0°C), operate
the engine at moderate speeds for five minutes
before full loads are applied.

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!
•
Failure to properly maintain your vehicle or
perform repairs and service when necessary
could result in more costly repairs, damage
to other components or negatively impact
vehicle performance. Immediately have po-
tential malfunctions examined by an autho-
rized dealer or qualified repair center.
•Your vehicle has been built with improved
fluids that protect the performance and
durability of your vehicle and also allow
extended maintenance intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by
the New Vehicle Limited Warranty. If a
flush is needed because of component
malfunction, use only the specified fluid for
the flushing procedure.
Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at the
correct level. The best time to check the engine
oil level is about five minutes after a fully
warmed up engine is shut off or before starting
the engine after it has sat overnight.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the SAFE level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine. Change Engine Oil
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
