2006 DODGE RAM 3500 DIESEL low fuel

A MESSAGE FROM DAIMLERCHRYSLER
CORPORATION
DaimlerChrysler Corporation and Cummins welcome
you as a new Dodge Ram Cummins Turbo Diesel-
powered truck owner.
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 tofollow 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.

•The lap portion should be low on the hips and as snug
as possible.
•Check 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 break-in period due to its construction. Normal
operation is allowed, provided the following recommen-
dations 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.
•Warm up the engine before placing it under load.
•Do not operate the engine at idle for prolonged
periods.
•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
•Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins Diesel
engine, engine run-in is enhanced by loaded operating
conditions which allow the engine parts to achieve final
finish and fit during the first 6,000 miles (10 000 km).

NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles estimated
driving distance, the DTE display will change to an
alternating test display of “LO” and “FUEL”. This dis-
play will continue until the vehicle runs out of fuel.
Adding a significant amount of fuel to the vehicle will
turn off the “LO FUEL” text and a new DTE value will be
displayed, based on the current values in the DTE
calculation and the current fuel tank level.
NOTE:It is possible for DTE to display “LO FUEL”
before the low fuel warning light turns on in the instru-
ment cluster. This could occur because low fuel warning
is set to a specified fuel tank volume and DTE is an
estimated distance calculation based on fuel economy
and remaining fuel tank volume.Ram fuel tank volumes are as follows:
•26 gallons - 1500 short box models
•34 gallons - 1500 Quad Cab (if equipped)/2500/3500
short box models
•35 gallons - 1500/2500/3500 long box models
Trip Odometer (ODO)
This display shows the distance traveled since the last
reset. Resetting of this screen will cause the trip odometer
to change to Zero.
Elapsed Time (ET)
This display shows the accumulated ignition ON time
since the last reset. Resetting the Elapsed Time will cause
the display to change to Zero.

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltage Gauge
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. Ifthe pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating. (See page 124 for more informa-
tion.)
4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.

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.
18. Brake System Warning Light
This light illuminates when the ignition key is turned to
the ON position and remains on for a few seconds. If the
light stays on longer, it may be an indication that the
parking brake has not been released. This light will
illuminate if the brake fluid is low, especially when
braking or accelerating hard. This light will illuminate if
the ABS indicator light has a malfunction. This light will
flash if the engine is running and the parking brake is on.If the light remains on when the parking brake is
released, it indicates a possible brake hydraulic system
malfunction. In this case, the light will remain on until
the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.
19. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual. This
light will come on when the ignition key is turned to the
ON position and may stay on for five seconds. If the ABS
light remains on or comes on during driving, it indicates
182 UNDERSTANDING YOUR INSTRUMENT PANEL

that the anti-lock portion of the brake system is not
functioning and that service is required. See your autho-
rized dealer immediately. The ABS light could also
illuminate during loss of traction and remain illuminated
until the brake pedal is pressed.
20. Cargo Light
The Cargo Lamp light will illuminate when the Cargo
Lamp is activated by pressing the Cargo Light Button on
the headlight switch.
21. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required.22. Front Fog Light Indicator — If Equipped
This light shows when the front fog lights are ON.
23. Water In Fuel Indicator
Indicates there is water detected in the fuel
filter bowl. Refer to the Maintenance section,
Draining Fuel/Water Separator Filter, for water
drain procedure. (See page 387 for more infor-
mation.)
24. Low Washer Fluid Light
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.

25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g. snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
26. Wait To Start Indicator
The Wait To Start Indicator will illuminate when
the ignition key is first turned to the ON position.
Wait until the Wait To Start Indicator turns OFF then start
the vehicle.27. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
28. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
29. Low Fuel Warning Light
Glows when the pointer is between “E” and 1/8
indication mark (approximately 15% of tank vol-
ume) on the fuel gauge. When the fuel gauge
pointer is on “E” (equivalent to Distance To Empty [DTE]
= 0 on the overhead console if so equipped) there is
reserve fuel capacity, which corresponds to approxi-
mately 8% of tank volume. This reserve capacity was put
in place to prevent the likelihood of customers running
