Engine oil not designated by the FCA or
Cummins Material Standards and API CK-4
should not be used, as engine and exhaust
system durability may be compromised. The
engine oil filler cap also shows the
recommended engine oil viscosity for your
engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in
“Servicing And Maintenance” for further
information.
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed. Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number 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.
Engine Oil Filter Selection
This manufacturer's engines have a full-flow
type disposable oil filter. Use a filter of this type
for replacement. The quality of replacement
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine oil filters are high quality
oil filters and are recommended.

the Diesel Particulate Filter, the engine idle
speed will return to normal when the brake
pedal is applied. A small change in engine tone
or a slight change in engine performance while
accelerating may also be noticeable at speeds
below 20 mph (32 km/h). This operating mode
may last for up to an hour of idle time, or around
20 minutes of driving time.
Additionally, your vehicle has the ability to alert
you to additional maintenance required on your
truck or engine.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component of selective catalytic
reduction (SCR) systems, which help diesel
vehicles meet stringent emission regulations.
DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx)
into harmless nitrogen and water vapor.
Refer to “Fluids And Lubricants” in “Technical
Specification” for further information.
You can receive assistance in locating DEF in
the United States by calling 866-RAM-INFO
(866-726-4636). In Canada call
1–800–465–2001 (English) or
1–800–387–9983 (French)
You can receive assistance in locating DEF by
contacting an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, decklid, sliding
doors and hood hinges, should be lubricated
periodically with a lithium based grease, such as Mopar Spray White Lube to ensure quiet,
easy operation and to protect against rust and
wear. Prior to the application of any lubricant,
the parts concerned should be wiped clean to
remove dust and grit; after lubricating, excess
oil and grease should be removed. Particular
attention should also be given to hood latching
components to ensure proper function. When
performing other underhood services, the hood
latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Autumn and
Spring. Apply a small amount of a high quality
lubricant, such as Mopar Lock Cylinder
Lubricant directly into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and
the windshield periodically with a sponge or soft
cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry
windshield.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials 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.

8. Reinsert the dipstick. Check for leaks.
Release the parking brake.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two COLD (lower) holes
on the dipstick with the fluid at 68-86°F /
20-30°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
Fluid And Filter Changes — Eight-Speed
Transmission
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not
required. However, change the fluid and filter if
the fluid becomes contaminated (with water,
etc.), or if the transmission is disassembled for
any reason.
Fluid And Filter Changes — Six Speed
Transmission
Refer to the “Maintenance Plan” for the proper
maintenance intervals.
In addition, change the fluid and filters if the
fluid becomes contaminated (with water, etc.),
or if the transmission is disassembled for any
reason.
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. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. This
inspection should be made with the vehicle in a
level position.
For all 2500/3500 Model axles, the fluid level
should be 1/4 in ± 1/4 in (6.4 mm ± 6.4 mm)
below the fill hole on the 9.25 in front, 11.5 in
rear axle, and 12.0 in rear axle.
Drain And Refill
Refer to the “Maintenance Plan” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
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 DO REQUIRE limited
slip oil additive (friction modifiers).
CAUTION!
If the fluid temperature is below 50°F (10°C)
it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough
to produce an accurate reading. Run the
engine at idle, in PARK, to warm the fluid.

458TECHNICAL SPECIFICATIONS
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if
stored properly, provides for protection against
fuel oxidation for up to six months.
Fuel Water Separation — Must Use Mopar/
Cummins Approved Fuel Filter Elements
You must use Mopar/Cummins approved fuel
filter elements in both your engine mounted
filter and frame mounted filter.
Biodiesel fuel has a natural affinity to water and
water accelerates microbial growth. Your
Mopar/Cummins filtration system is designed
to provide adequate fuel water separation
capabilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for
both storage and operation. Precautions can be
necessary at low ambient temperatures, such
as storing the fuel in a heated building or a
heated storage tank, or using cold temperature
additives.
Fuel In Oil Dilution — Must Adhere To
Required Oil Change Interval
Fuel dilution of lubricating oil has been
observed with the use of biodiesel fuel. Fuel in
oil must not exceed 5%. To ensure this limit is
met your oil change interval must be
maintained to the following schedule:
Ram PickUp 2500/3500 Only — 15,000 Miles*
(*unless otherwise notified with a oil service
message)
CAUTION!

Under no circumstances should oil change
intervals exceed 15,000 miles (24 000 km)
pickup or 12,500 miles (20 000 km) chassis
cab if operation occurs with greater than 5%
biodiesel blends. Oil change intervals should
not exceed 6 months in either case. Failure
to comply with these Oil Change require -
ments for vehicles operating on biodiesel
blends up to B20 may result in premature
engine wear. Such wear is not covered by the
New Vehicle Limited Warranty.

B20 Biodiesel capable: The engine may
suffer severe damage if operated with
concentrations of Biodiesel higher than
20%.
