2004 DODGE DAKOTA check engine

U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer shows individual trip mileage. To
toggle between the odometer and the trip odometer,
press the Odometer/Trip Odometer Button.
27. Cruise Light
This indicator lights when the electronic speed control
system is turned on.
28. Coolant Temperature Light (Clusters Without A
Gauge)
This light warns of an overheated engine con-
dition. For a bulb check, this light will come on
momentarily when the ignition is turned On. If
the light turns on while driving, stop the vehicle and
shut off the engine as soon as possible.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature light is on,
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the light turns
off. If the if the light remains on, turn the engine off
immediately, and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.

29. Engine Oil Pressure Indicator Light (Clusters
Without A Gauge)
This light indicates that the engine oil pressure
has become too low. For a bulb check, this light
will come on momentarily when the ignition is turned
On. If the light turns on while driving, stop the vehicle
and shut off the engine as soon as possible. Immediate
service should be obtained.
30. Voltage Light (Clusters Without A Gauge)
This light monitors the electrical system volt-
age. The light should turn on momentarily as
the engine is started. If the light stays on or turns on
while driving, it indicates a problem with the charging
system. Immediate service should be obtained.ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ªONº or
ªACCº position.
When the ignition switch is in the ªOFFº position, or
when the radio frequency is being displayed, time keep-
ing is accurately maintained.
Clock Setting Procedure
1. Turn the ignition switch to the ªONº or ªACCº
position. Using the point of a ballpoint pen or similar
object, press either the ªHº (Hour) or ªMº (Minute)
buttons on the radio. The display will show the time.
2. Press the ªHº button to set hours or the ªMº button to
set minutes. The time setting will increase each time you

switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of PARK.
Gear Ranges
DO NOT race the engine when shifting from Park or
Neutral position into another gear range.
ªPº Park
This position supplements parking brake by locking the
transmission. The engine can be started in this range.
Never use Park while the vehicle is in motion. Apply the
parking brake when leaving vehicle in this range. Always
apply the parking brake first, then place the selector in
the Park position.
WARNING!
Your vehicle could move and injure you and others if
it is not completely in P (Park). Check by trying to
move the gearshift lever back and forth without first
pulling the lever toward you, after you have set it in
P. Make sure it is in Park before leaving the vehicle.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
WARNING!
It is dangerous to shift the selector lever out of ªPº or
ªNº if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
ªRº Reverse
Use this range only after the vehicle has come to a
complete stop.

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing METHANOL.
Gasoline containing methanol may damage critical
fuel system components.
MMT In Gasoline
MMT is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasolines
blended with MMT provide no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT reduce spark plug
life and reduce emission system performance in some
vehicles. We recommend that gasolines free of MMT beused in your vehicle. The MMT content of gasoline may
not be indicated on the gasoline pump; therefore, you
should ask your gasoline retailer whether or not his/her
gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at levels
higher than allowed in the United States. MMT is pro-
hibited in Federal and California reformulated gasolines.
Sulfur In Gasoline
If you live in the northeast United States, your vehicle
may have been designed to meet California low emission
standards with Cleaner-Burning California reformulated
gasoline with low sulfur. If such fuels are not available in
states adopting California emission standards, your ve-
hicles will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be adversely affected. Gasoline sold outside of
California is permitted to have higher sulfur levels which
may affect the performance of the vehicle's catalytic
converter. This may cause the Check Engine or Service
Engine Soon light to illuminate. We recommend that you
try a different brand of unleaded gasoline having lower

sulfur to determine if the problem is fuel related prior to
returning your vehicle to an authorized dealer for ser-
vice.
CAUTION!
If the Check Engine or Service Engine Soon light is
flashing, immediate service is required; see onboard
diagnostics system section.
Materials Added To Fuel
All gasolines sold in the United States are required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door. If the gas cap is
lost or damaged, be sure the replacement cap is for use
with this vehicle.
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
186 STARTING AND OPERATING

WARNING!
²Remove the fuel tank filler tube cap (gas cap)
slowly to prevent fuel spray from the filler neck
which may cause injury.
²The volatility of some gasolines may cause a
buildup of pressure in the fuel tank that may
increase while you drive. This pressure can result
in a spray of gasoline and/or vapors when the cap
is removed from a hot vehicle. Removing the cap
slowly allows the pressure to vent and prevents
fuel spray.
²Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
²Never add fuel to the vehicle when the engine is
running.
Fuel Tank Filler Tube
NOTE:
On some models, the fuel tank filler tube has a
restricting door about 2 inches (50 mm) down from the
opening. If fuel is poured from a portable container, the
container should have a flexible nozzle long enough to
force open the restricting door.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
NOTE:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
NOTE:Tighten the gas cap until you hear a ªclickingº
sound. This is an indication that the gas cap is properly
tightened.
The Check Engine light will come on if the gas cap is
not properly secured. Make sure that the gas cap is
tightened each time the vehicle is refueled.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL light will blink for approximately 5
seconds and then remain on until the first engine
crank or the key is turned off. This means that your
vehicle's OBD system isnot readyand you should
notproceed to the I/M station.
b. The MIL light will remain fully illuminated until
the first engine crank or the key is turned off. This
means that your vehicle's OBD system isreadyand
you can proceed to the I/M station.
If your OBD system isnot ready,you should see your
dealer or repair facility. If your vehicle was recently
