Radial Ply Tires
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
• The tire has not been driven on when flat.
• The damage is only on the tread section of your tire (sidewall damage is not repair-
able).
• The puncture is no greater thana¼ofan inch (6 mm).
Consult an authorized tire dealer for tire re-
pairs 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).
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 capabili-
ties and needs to be replaced immediately. A
Run Flat tire is not repairable.
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.
See the tire pressure monitoring section for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice con-
ditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
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 sec-
onds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.

CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products 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 recom-
mended.
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. Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat WheelsCAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing com-
pounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty.
HAND WASH ONLY USING MILD SOAP
AND WATER WITH A SOFT CLOTH. Used
on a regular basis; this is all that is re-
quired to maintain this finish.
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National High-
way Traffic Safety Administration. Thespecific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must con-
form to Federal safety requirements in
addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The rela-
tive performance of tires depends
upon the actual conditions of their
use, however, and may depart signifi-
cantly from the norm due to variations
in driving habits, service practices,
and differences in road characteristics
and climate.

FLUIDS AND LUBRICANTS — 3.0L DIESEL ENGINE
Engine
ComponentFluid, Lubricant, or Genuine Part
Engine Coolant We recommend you use Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology).
Engine Oil We recommend you use 5W-40
syntheticengine oil such as Mopar or Shell Rotella that meets FCA Material Standard
MS-10902 and the API CJ-4 engine oil category is required.
Engine Oil Filter We recommend you use Mopar Engine Oil Filters.
Fuel Filters We recommend you use Mopar Fuel Filter. Must meet 3 micron rating.
Using a fuel filter that does not meet the
manufacturers filtration and water separating requirements can severely impact fuel system life and reliability.
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requires that you must fuel this vehicle
with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur Highway Diesel
fuel (500 ppm Sulfur maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide good
performance. We recommend you use a blend of up to 5% biodiesel, meeting ASTM specification D-975 with your diesel
engine.This vehicle is compatible with biodiesel blends greater than 5% but no greater than 20% biodiesel meeting ASTM
specification D-7467 provided the shortened maintenance intervals are followed as directed.
Diesel Exhaust Fluid Mopar Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the ISO 22241 standard.
Use of fluids not API Certified to ISO 22241 may result in system damage.
NOTE:
If climatized or diesel Number 1 ULSD fuel is
not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions,
Mopar Premium Diesel Fuel Treatment (or
equivalent) is recommended to avoid gelling.CAUTION!
• Mixing of engine coolant (antifreeze)
other than specified Organic Additive
Technology (OAT) engine coolant (anti-
freeze), may result in engine damage
CAUTION!
and may decrease corrosion protection.
