the EPA Heavy Duty Diesel Engine Emissions
Standards. These systems are seamlessly
integrated into your vehicle and managed by the
Cummins® Powertrain Control Module (PCM). The
PCM manages engine combustion to allow the
exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or
interaction on your part.
If the engine is allowed to idle or the truck is driven
on low engine speed drive cycles for more than two
hours, the system will automatically enter an
emissions operating mode that will increase the
engine idle speed to 1,050 RPM. While in this
mode, which is designed to help maintain 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 Ú page 81.
DIESEL EXHAUST FLUID (DEF)
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
Úpage 404.
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.
Avoid using the wiper blades to remove frost or ice
from the windshield. Keep the blade rubber out of
contact with petroleum products such as engine
oil, gasoline, etc.
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 oper
-
ate your vehicle in areas where your exhaust sys -
tem can contact anything that can burn.

360SERVICING AND MAINTENANCE
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 trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
Fluid And Filter Changes — 8-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 — 6-Speed
Transmission
For the proper maintenance intervals Úpage 329.
In addition, change the fluid and filters if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer’s specified
transmission fluid Ú page 407. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid. No chemical flushes
should be used in any transmission; only the
approved lubricant should be used.
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. This inspection
should be made with the vehicle in a level position.
When checking the fluid level, the vehicle should
be in a level position. The fluid level at room
temperature should be as follows:
3500 Front Axle: ¼ inch ± ¼ inch (6.4 mm ±
6.4 mm) below the bottom of the fill hole.
3500 Rear Axle: ¼ inch ± ¼ inch (6.4 mm ±
6.4 mm) below the bottom of the fill hole.
4500/5500 Front Axle: ¼ inch +/- ¼ inch (6.4 mm
± 6.4 mm) below the bottom of the fill hole.
4500/5500 Rear Axle: 1/8 inch +/- 1/8 inch
(3.2 mm +/- 3.2 mm) below the bottom of the fill
hole.
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.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder, and (for 6-speed
transmissions) will require more frequent fluid
and filter changes Ú page 407.

402TECHNICAL SPECIFICATIONS
comply with Oil Change requirements for vehicles
operating on biodiesel blends up to B20 will result
in premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
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 greater then 5% but not greater than
20% (B6-B20). There are no unique restrictions for
the use of B5. 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.
Fuel Quality — Must Comply With ASTM
Standards
The quality of biodiesel fuel may vary widely. Only
fuel produced by a BQ9000 supplier to the
following specifications may be blended to meet
biodiesel blend (B6–B20) fuel meeting ASTM
specification D-7467:
Petrodiesel fuel meeting ASTM specification
D-975 and biodiesel fuel (B100) meeting ASTM
specification D-6751.
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.
Biodiesel 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 3500/4500/5500 Chassis Cab —
12,500 Miles (20,000 km)*
(*unless otherwise notified with a oil service
message)
CAUTION!
Under no circumstances should oil change
intervals exceed 12,500 miles (20,000 km) if
operation occurs with greater than 5%
biodiesel blends. Oil change intervals should
not exceed six months in either case. Failure to
comply with these Oil Change requirements 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 concentra -
tions of Biodiesel higher than 20%.
