2004 DODGE RAM 2500 DIESEL Operation

Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system which is not
covered by the warranty. Proper maintenance of the
engine fuel filter and fuel tank is essential. (See Section 7
for Maintenance Procedures).
NOTE:Climatized diesel fuel is a blend of Number 2
and Number 1 Diesel fuel which reduces the temperature
at which wax crystals form in the fuel.
Bulk Fuel Storage
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of ªmicrobes.º These
microbes form ªslimeº that will clog fuel filters and lines.
Drain condensation from the supply tank and change the
line filter on a regular basis.
Fuel Specifications
The Cummins Turbocharged, Charge Air Cooled, Diesel
engine has been developed to take advantage of the high
energy content and generally lower cost No. 2 diesel fuel
or No. 2 climatized diesel fuels. Experience has shown
that it also operates on No. 1 diesel fuels or other fuels
within the specifications in the following chart.
NOTE:As sufficient testing has not been completed,
organically blended diesel fuels (e.g. biodiesel, ethanol,
and methanol blends) are not recommended or approved
for use with your Cummins Diesel equipped Dodge Ram
Truck.
NOTE:In addition, commercially available fuel addi-
tives are not necessary for the proper operation of your
Cummins Diesel equipped Dodge Ram Truck.
NOTE:No. 1 diesel fuel should only be used where
extended arctic conditions (-10ÉF or 23ÉC) exist.

Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
270 STARTING AND OPERATING

Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Also overloading can
shorten the life of your vehicle.
An EXAMPLE of a loaded vehicle is shown in the
following chart. Note that neither GVWR nor GAWR
capabilities are exceeded. Overloading can cause poten-
tial safety hazards and shorten service life.NOTE: The weights shown in this chart are not
necessarily the weights for your vehicle. Also, the
amount of load added to both the front and rear axles
can be computed after the vehicle has been weighed
both in its(curb weight(condition, and in its(loaded
and ready for operation(condition.
Gross Vehicle Weight Rating (GVWR) 6500 LBS.

TRAILER TOWING
All Dodge Ram Pickup trucks are intended to tow trailers
up to 2,000 lbs (907 kg) without added equipment or
alterations to standard equipment. Your vehicle may be
factory equipped for safe towing of trailers weighing
over 2,000 lbs (907 kg) with the optional Trailer Tow Prep
Package. See your Dodge dealer for package content.
To Maintain Warranty Coverage
Follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Definitions
The following trailer towing related terminology defini-
tions will assist in understanding the subsequent sec-
tions:
GROSS COMBINATION WEIGHT RATING (GCWR)
is the total permissible weight of your vehicle and trailer
when weighed in combination. (Note that GCWR ratingsinclude a 68 kg (150 lb.) allowance for the presence of a
driver.) Tongue Weight (of a trailer) is the weight placed
on a vehicle's trailer hitch by the trailer.
GROSS TRAILER WEIGHT (GTW)is the weight of the
trailer plus the weight of all cargo, consumables and
equipment (permanent or temporary) loaded in or on the
trailer in its9loaded and ready for operation9condition.
TRAILER SWAY CONTROLis a telescoping link that
can be installed between the hitch receiver and the trailer
tongue that typically provides adjustable friction associ-
ated with the telescoping motion to dampen any un-
wanted trailer swaying motions while traveling.
272 STARTING AND OPERATING

of the plow. Front end tow-in should be checked and
reset if necessary at the beginning and end of the
snowplow season. This will help prevent uneven tire
wear.
The blade should be lowered whenever the vehicle is
parked.
Maintain and operate your vehicle and snowplow equip-
ment following the recommendations provided by the
specific snowplow manufacturer.
Over the Road Operation With Snowplow
Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
Methods For Removing Snow
Operating Tips
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator
should be familiar with the area and surface to be
cleaned. Reduce speed and use extreme caution when
plowing unfamiliar areas or under poor visibility.
284 STARTING AND OPERATING

NOTE:During snowplow usage on vehicles equipped
with an overhead console module, the outside tempera-
ture display will show higher temperatures than the
outside ambient temperature. The higher displayed tem-
perature is due to blocked or reduced airflow to the
underhood ambient temperature sensor by the snow-
plow. This is common and outside temperature display
operation will return to normal when the snowplow is
removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer's instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and driv-
etrain damage, the following precautions should be ob-
served.
²Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
²Vehicles with 48RE transmissions should use 4L range
when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
²Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.
