check engine light DODGE NEON 2004 2.G Owners Manual

SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized operation of the vehicle by disabling the engine.
The system will shut the engine off after 2 seconds of
running if an invalid key is used to start the vehicle. This
system utilizes ignition keys which have an electronic
chip (transponder) embedded into them. Only keys that
have been programmed to the vehicle can be used to start
and operate the vehicle.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the Theft Alarm/
Immobilizer Light will come on for three (3) seconds
immediately after the ignition switch is turned on for a
bulb check. Afterwards, if the bulb remains on, this
indicates a problem with the electronics.
If the bulb begins to flash after the bulb check, this
indicates that an invalid key has been used to start the
vehicle. Both of these conditions will result in the engine
being shut off after two (2) seconds of running.Keep in mind that a key which has not been programmed
is also considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
If the Theft Alarm/Immobilizer Light comes on during
normal vehicle operation (vehicle has been running for
longer than 10 seconds), a fault has been detected in the
electronics and the vehicle should be serviced as soon as
possible.
NOTE:
²
The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Sentry Keys, or
any other transponder equipped components on the
same keychain willnot
cause a key-related (tran-
sponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used
when starting the vehicle. Cell phones, pagers, or
other RF electronics will not cause interference with
this system.

SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
To avoid drawing exhaust gases into the vehicle, close the
trunk while driving. However, if for some reason it mustremain open, close all windows. Adjust the heating or
cooling system to force outside air into the vehicle. Set
the blower at high speed.
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.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (bent retractor, torn
webbing, etc.). 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 to ON/RUN. If the bulb is
not lit during starting, have it replaced. If the light stays
on or comes on while driving, have the system checked
by an authorized dealer.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Front Fog Light Indicator Ð If Equipped
This light shows when the front fog lights are
ON.
2. Brake System Warning Light
This light monitors various brake functions,
including brake fluid level and parking
brake application. If the brake light comes
on, it may indicate that the parking brake is
applied, or there is a low brake fluid level. On vehicles
equipped with Anti-lock brakes (ABS), it may also
indicate an ABS malfunction that could lead to re-
duced braking performance.WARNING!
Driving a vehicle with the brake light on is danger-
ous. A significant decrease in braking performance
or vehicle stability during braking may occur. It will
take you longer to stop the vehicle or will make your
vehicle harder to control. You could have an acci-
dent. Have the vehicle checked immediately.
The operation of the Brake Warning light can be checked
by turning the ignition key from the OFF to the ON
position. The light should illuminate for three seconds, or
until the engine is started, whichever comes first. The
light should then go out unless the parking brake is
applied or a brake fault is detected. If the light does not
illuminate, have the light inspected and serviced as soon
as possible.
The light will also come on when the parking brake is
applied with the ignition in the ON position.
NOTE:This light shows only that the parking brake is
on. It does not show the degree of brake application.
78 UNDERSTANDING YOUR INSTRUMENT PANEL

If the parking brake is off and the light remains on, have
the brake system inspected as soon as possible.
3. Anti-Lock Warning Light (ABS) Ð If Equipped
This light monitors the Anti-Lock Brake System
(ABS) 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 as long as four
seconds.
If the ABS light remains on or comes on during driving,
it indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required, however,
the conventional brake system will continue to operate
normally provided that the BRAKE warning light is not
on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefit of Anti-Lock
Brakes.
The warning light should be checked frequently to assure
that it is operating properly. Turn the ignition key to apoint midway between ON and START. The light should
come on. If the light does not come on, have the system
checked by an authorized dealer.
4. Speedometer
Indicates vehicle speed.
5. Turn Signal Indicators
The arrows will flash in unison with the exterior
turn signal, when using the turn signal lever.
6. High Beam Indicator
This light shows that the headlights are on high
beam. Pull the turn signal lever toward the
steering wheel to switch the headlights from high or
low beam.
7. Tachometer Ð If Equipped
The white area of the scale shows the permissible engine
revolutions-per-minute (rpm x 1000) for each gear range.
Before reaching the red area, ease up on the accelerator to
prevent engine damage.

come on and remain on when the ignition key is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on during starting, have the system checked
by an authorized dealer.
If the light comes on and remains on while driving, stop
the vehicle and shut off the engine. DO NOT OPERATE
THE VEHICLE UNTIL THE CAUSE IS CORRECTED.
The light does not show the quantity of oil in the engine.
This can be determined using the procedure shown in
Section 7.
9. Seat Belt Reminder Light
When the ignition key is first turned on, this
light will come on for about six seconds. A
chime will sound if you have not pulled the
shoulder belt out of the retractor. This is a reminder to
ªbuckle upº. If you do not buckle up, the light will
remain on.10. Charging System Light
This light shows the status of the electrical
charging system. The light should come on
briefly when the ignition is first turned on and remain
on briefly as a bulb check. If the light stays on or
comes on while driving, it means that there is a
problem with the charging system. Obtain SERVICE
IMMEDIATELY.
11. Airbag Light
The light comes on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light does not
come on during starting, stays on, or comes on while
driving, have the system checked by an authorized
dealer.
12. Theft Alarm Light Ð If Equipped
This light will flash rapidly for several seconds when the
alarm system is arming. The light will begin to flash
slowly indicating that the system is armed.
13. Fuel Door Reminder

14. Fuel Gauge
When the ignition key is in the ON position, the
pointer will show the level of fuel remaining in
the fuel tank.
15. Low Fuel Light Ð If Equipped
NOTE:
The Low Fuel Light and Chime feature only
functions on vehicles equipped with a tachometer.
When the fuel level drops to about 1/8 tank, the
fuel symbol will light and a single chime will
sound. The light will remain on until fuel is
added. If the fuel level drops to about 1/2 gallon, the
fuel symbol will begin to flash and the chime will
sound several times.
16. Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD that monitors emissions,
engine, and automatic transmission control
systems. The light will illuminate briefly when the key
is in the ON/RUN position before engine start. If the
bulb does not come on when turning the key from
OFF to ON/RUN, have the condition checked
promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
17. Odometer/Trip Odometer Reset Knob
Press this knob to switch between the odometer and trip
odometer. While the trip odometer is being displayed,
press and hold this knob for a few seconds to reset the
trip odometer to zero miles/kilometers.

Malfunction Indicator light to illuminate. The manufac-
turer recommends 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 service.
CAUTION!
If the Check Engine or Service Engine Soon light is
flashing, immediate service is required. See the On
Board Diagnostics paragraph in the Maintenance
section of this manual.
Materials Added to Fuel
All gasoline sold in the United States is 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.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system, and could result
in loss of warranty coverage.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.

To change the aim of the windshield washers, place a
safety pin into the nozzle opening and move the nozzle
slightly. Continue making slight adjustments until you
obtain the desired pattern.
Windshield Washer Reservoir
The washer fluid reservoir is located in the engine
compartment and should be checked for fluid level at
regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze)
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if exhaust fumes can be detected inside the vehicle; or
when the underside or rear of the vehicle is damaged;
have a competent mechanic inspect the complete exhaust
system and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep

warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²
Check tire pressure and look for unusual wear or
damage.
