fuel DODGE RAM 2500 DIESEL 2004 3.G Owners Manual

Almost 100% of the heavy duty trucks in the United
States are diesel powered because of the fuel economy,
rugged durability, and high torque which permits pulling
heavy loads. Cummins engines power well over half of
these trucks. Now this same technology and proven
performance is yours in your new Dodge Ram truck
equipped with the Cummins 5.9 liter, Turbocharged,
Charge Air Cooled, Diesel engine.
Your diesel truck will sound, feel, drive, and operate
differently from a gasoline-powered truck. It is important
that you read and understand this manual. You may find
that some of the starting, operating, and maintenance
procedures are different. However, they are simple to
follow and careful adherence to them will ensure that
you take full advantage of the features of this engine.
Thank you for choosing the Dodge Ram truck with
Cummins Turbo Diesel power.HOW TO USE THIS MANUAL

Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back should use the lap/shoulder belt in a rear seat.
²Make sure that the child is upright in the seat.
²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
NEW ENGINE BREAK-IN
Your Cummins 24 Valve Turbo Diesel engine does not
require a normal break-in period due to its construction.
Normal operation is allowed, provided the following
recommendations are followed:
NOTE:Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
²Warm up the engine before placing it under load.
²Do not operate the engine at idle for prolonged
periods.
²Use the appropriate transmission gear to prevent
engine lugging.
²Observe vehicle oil pressure and temperature indica-
tors.

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing, etc.)
or if the front airbags have deployed. If there is any question
regarding belt or retractor condition, replace the belt.
Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see you
authorized dealer. If the light stays on, flickers or comes
on while driving, have the system checked by an autho-
rized dealer. If there is a problem with the airbag light the
seatbelt light will flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.
Lights
Check the operation of all exterior lights. Check turn signal
and high beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.

Global Reset
If the RESET button is pressed twice within 4 seconds
while in any of the 3 resettable displays, the Global Reset
will reset all 3 displays.
Step Button
Use this button to choose or cycle through the four trip
conditions.
Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset. This
display mode becomes less sensitive to instantaneous
changes in fuel consumption as the number of total
vehicle miles since the last reset increases. It is suggested
that this mode be reset periodically for general operation
or when driving conditions change significantly (for
example, at the end of a trip or when a trailer is
connected or disconnected).
Distance To Empty (DTE)
Shows the estimated distance that can be travelled with
the fuel remaining in the tank. The estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level.
When Distance To Empty = 0, the fuel gauge pointer will
initially be on the red ªEº marker. At this point (fuel
gauge pointer on the red ªEº marker) there is reserve fuel

capacity, which corresponds to approximately 8% of tank
volume. This reserve capacity was put in place to prevent
the likelihood of customers running out of fuel when
operating at maximum load conditions in areas where
there aren't many gas stations.
NOTE:The Distance To Empty will remain equal to
zero, until the vehicle runs out of fuel or is refueled.
Ram fuel tank volumes are as follows:
²26 gallons - 1500 short box models
²34 gallons - 1500 Quad Cab (if equipped)/2500/3500

INSTRUMENT CLUSTER DESCRIPTION
1. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
