2004 DODGE RAM 2500 DIESEL ignition

To Set At A Desired Speed
When the vehicle has reached the desired speed, press
and release the SET button. Release the accelerator and
the vehicle will operate at the selected speed.
To Deactivate
A soft tap on the brake pedal, normal braking, clutch
pressure while slowing the vehicle, or pressing the CAN-
CEL button will deactivate speed control without erasing
the memory. Pushing the ON/OFF button to the OFF
position or turning off the ignition erases the memory.
WARNING!
Leaving the Speed Control ON when not in use is
dangerous. You could accidentally set the system to
cause it to go faster than you want. You could lose
control and have an accident. Always leave the
system OFF when you aren't using it.
To Resume Speed
To resume a previously set speed, push and release the
RESUME button. Resume can be used at any speed above
30 mph (50 km/h).

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
short box models
²35 gallons - 1500/2500/3500 long box models
Trip Odometer (ODO)
This display shows the distance traveled since the last
reset.
Elapsed Time (ET)
This display shows the accumulated ignition ON time
since the last reset.

Manual Compass Calibration
NOTE:To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass.
If the compass appears erratic and the CAL symbol does
not appear, you must manually put the compass into the
ªCalibrationº mode.
To Put Into a Calibration Mode
Turn on the ignition and set the display to ªCompass/
Temperature.º Press and hold the RESET button to
change the display between VAR (compass variance) and
CAL (compass calibration) modes. When the CAL sym-
bol is displayed complete one 360 degree turn in an area
free from large metal objects or power lines. The CAL
symbol will turn off and the compass will function
normally.Compass Varianceis the difference between magnetic
north and geographic north. In some areas of the country,
the difference between magnetic and geographic north is
great enough to cause the compass to give false readings.
If this occurs, the compass variance must be set according
to the Compass Variance Map.
118 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To set the variance: Turn the ignition ON and set the
display to ªCompass/Temperature.º Press the RESET
button approximately five seconds. The last variance
zone number will be displayed. Press the STEP button to
select the new variance zone and press the RESET button
to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.

ELECTRICAL POWER OUTLETS
The auxiliary electrical outlet can provide power for in
cab accessories designed for use with the standard ªcigar
lighterº plug. The outlet is located in the instrument
panel below the ash receiver. A cap is attached to the
outlet base indicating ªPower Outletº 12V-20A.
There is an additional Power Outlet in the center console
of a 40/20/40 seat (if equipped).
The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.CAUTION!
Electrical Outlet Use With Engine Off
²Many accessories that can be plugged in draw
power from the vehicle's battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle's battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
²Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter-
mittently and with greater caution.
²After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle's battery.

CIGAR LIGHTER AND ASH RECEIVER
The ash receiver is opened and closed bypushingon the
front surface of the receiver and then allowing the
receiver to open.
The cigar lighter is located above and to the left of the ash
receiver.
As a child safety precaution, the lighter only operates
with the ignition switch ON. It heats when pushed in and
pops out automatically when ready for use.To preserve
the heating element, do not hold the lighter in the
heating position.

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.

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. If
the 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 ªCheck Gagesº indicator will illuminate
and a single chime will sound.
3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating.
4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.CAUTION!
Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Indicator Light
The indicator lights and remains lit for 6 to 8 seconds
when the ignition is first turned on. If the light stays on,
flickers or comes on while driving, have the airbag
system checked by an authorized dealer.
6. High Beam Indicator
This indicator shows that headlights are on high
beam.
