Use only the manufacturer's recommended fluids
Úpage 473.
NOTE:Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approximately
30 seconds. This is normal and will not harm the
engine. This characteristic can be caused by short
drive cycles. For example, if the vehicle is started
then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound.
Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine
continues to tick or if the Malfunction Indicator
Light (MIL) comes on, see the nearest authorized
dealer.
Engine Oil Selection — Diesel Engine

only use synthetic API approved engine oils.
Synthetic engine oils which do not have both the
correct API trademark and the correct SAE viscosity
grade numbers should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance may be
impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine
oil and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact an
authorized dealer, service station or governmental
agency for advice on how and where used oil and
oil filters can be safely discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.

EXHAUST SYSTEM
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected
inside the vehicle; or when the underside or rear of
the vehicle is damaged; have an authorized
technician inspect the complete exhaust system
and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes
to seep into the passenger compartment. In
addition, have the exhaust system inspected each
time the vehicle is raised for lubrication or oil
change. Replace as required.

WARNING!
Exhaust gases can injure or kill. They contain
Carbon Monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon
-
scious and can eventually poison you. To
avoid breathing CO see Ú page 368.
A hot exhaust system can start a fire if you
park over materials that can burn. Such mate -
rials might be grass or leaves coming into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.

REAR AXLE AND 4X4 FRONT DRIVING
A
XLE FLUID LEVEL
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level Úpage 476. This
inspection should be made with the vehicle in a
level position.
The fluid level should be even with the bottom of
the fill hole (within 1/4 in (6.4 mm) of edge of hole)
for the front axle and rear axle.
Drain And Refill
For the proper maintenance intervals Úpage 394.
Lubricant Selection
For further information Ú page 476.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differ -
ential components. Operation of the vehicle in
water, as may be encountered in some off-highway
types of service, will require draining and refilling
the axle to avoid damage. Limited-Slip Differentials
Rear axles equipped with a Limited Slip Differential
require that 5 oz. (148 ml) Mopar® Limited Slip
Additive be added to the gear lubricant
Ú
page 476. The Mopar® Limited Slip Additive
should be added to the gear lubricant whenever a
fluid change is made to an axle equipped with a
Limited Slip Differential.
NOTE:When refilling a limited slip differential axle which
requires a friction modification additive, the
additive should be added before the gear lubricant
to ensure proper additive fill.
TRANSFER CASE
Fluid Level Check
This fluid level can be checked by removing the
filler plug. The fluid level should be to the bottom
edge of the filler plug hole (or within 1/8 inch of the
bottom) with the vehicle in a level position.
Drain And Refill
For the proper maintenance intervals Úpage 394.
Selection Of Lubricant
Use only the manufacturer recommended fluid
Úpage 476.
FUSES
General Information
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. Do not place a fuse inside a circuit
breaker cavity or vice versa. Failure to use
proper fuses may result in serious personal
injury, fire and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, transmission
system) or steering system blows, contact an
authorized dealer.

454SERVICING 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 453. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label 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.
For more information relating to the Load Index
and Speed Symbol of a tire Ú page 445.
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.

470TECHNICAL SPECIFICATIONS
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, drain the
accumulated water from the fuel/water separator
filter using the fuel/water separator drain provided
on the fuel filter housing. If you buy good quality
fuel and follow the cold weather advice above, fuel
conditioners should not be required in your vehicle.
If available in your area, a high cetane “premium”
diesel fuel may offer improved cold-starting and
warm-up performance.
DIESEL FUEL SPECIFICATIONS
This diesel engine has been developed to take
advantage of the high energy content and
generally lower cost Number 2 Ultra Low Sulfur
diesel fuel or Number 2 Ultra Low Sulfur Climatized
diesel fuels.
NOTE:
If you accidentally fill the fuel tank with gasoline
or DEF on your diesel vehicle, do not start the
engine. Damage to the engine and fuel system
could occur. Please call an authorized dealer for
service.
A maximum blend of 5% biodiesel meeting
ASTM specification D-975 may be used with
your diesel engine without any adjustments to
regular service schedules.
Commercially available fuel additives are not
necessary for the proper operation of your
diesel engine.
Number 1 Ultra Low Sulfur diesel fuel should
only be used where extended arctic conditions
(-10°F or -23°C) exist.
BIODIESEL FUEL REQUIREMENTS
A maximum blend of 5% biodiesel meeting ASTM
specification D975 is recommended for use with
your diesel engine. If frequent operation with
Biodiesel blends that are between 6% and 20%
(B6–B20) is desired, the maintenance schedule is
subject to shorter intervals.
The oil and filter change along with fuel filter
replacement is subject to shorter intervals when
operating your engine on biodiesel greater than
5%. Do not use biodiesel greater than 20%. For regular use of biodiesel blends between 6%
and 20% (B6–B20) it is important that you
understand and comply with these requirements.
For further direction Ú
page 402.
Biodiesel is a fuel produced from renewable
resources typically derived from animal fat,
rapeseed oil (Rapeseed Methyl Ester (RME) base),
or soybean oil (Soy Methyl Ester (SME or SOME)
base).
Biodiesel fuel has inherent limitations which
require that you understand and adhere to the
following requirements if you use blends of
Biodiesel between 6% and 20% (B6–B20). There
are no unique restrictions for the use of B5.
CAUTION!
If the Water in Fuel Indicator Light remains on,
DO NOT START engine before you drain the water
from the fuel filter(s) to avoid engine damage
Ú page 412.
CAUTION!
Failure to comply with Oil Change requirements
for vehicles operating on biodiesel blends
between 6% and 20% (B6–B20) will result in
premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
CAUTION!
Use of blends greater than 20% is not approved.
Use of blends greater than 20% can result in
engine damage. Such damage is not covered by
the New Vehicle Limited Warranty.
