catalytic converter DODGE NEON SRT 2004 2.G Owners Manual

16. Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD that monitors engine con-
trol 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.
18. Odometer/Trip Odometer
Shows the total distance the vehicle has been driven.
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 changes during repair or
replacement, be sure to keep a record of the reading
before and after the service so the correct mileage can be
determined.
19. Door Ajar Indicator
This vacuum fluorescent indicator illuminates when a
door is not completely closed. If the door is open for more
than 8 minutes and the ignition key is in the OFF
position, the indicator will turn off.
66 UNDERSTANDING YOUR INSTRUMENT PANEL

If the engine fails to start within 15 seconds, turn the key
OFF wait 10 to 15 seconds, then repeat the normal
starting procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow the
procedure carefully. See section 6 of this manual for
jump starting instructions.
Extremely Cold Weather (below -20ÉF or -29ÉC)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
If Engine Fails to Start
If the engine fails to start after you have followed the
ªNORMAL STARTINGº procedure, it may be flooded.
Push the accelerator pedal all the way to the floor and
hold it there. Crank the engine for no more than 15
seconds. This should clear any excess fuel in case the
engine is flooded. Leave the ignition key in the ON
position, release the accelerator pedal and repeat the
ªNORMAL STARTINGº procedure.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
88 STARTING AND OPERATING

vehicle. The MMT content of gasoline may not be indi-
cated 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 higher
levels than allowed in the United States.
MMT is prohibited in both Federal and California refor-
mulated gasolines.
Sulfur in Gasoline
Your vehicle may have been designed to meet California
low emission standards with cleaner burning California
reformulated gasoline with low sulfur. This vehicle may
be sold nationwide. Your vehicle will operate satisfacto-
rily 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.
The manufacturer recommends that you try a differentbrand of unleaded gasoline having lower sulfur to deter-
mine 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.

7. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts until each
nut has been tightened twice. Correct wheel nut torque is
100 ft. lbs. (135 N´m.). If you are not sure about the
tightness, have them checked with a torgue wrench by
your dealer or at a service station.
8. Remove the wheel blocks and lower the jack until it is
free. Stow the lug wrench, replaced tire, and jack. Secure
all parts using the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
9. Adjust the tire pressure as soon as possible.
NOTE:The spare tire well is designed to hold the
compact spare tire or a deflated (flat) tire. A fully inflated
tire will not fit in the spare tire well.
JUMP-STARTING PROCEDURES DUE TO A LOW
BATTERY
WARNING!
Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is on. You can be hurt by the fan.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow this
procedure carefully.
WHAT TO DO IN EMERGENCIES 125

ONBOARD DIAGNOSTIC SYSTEM Ð OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, and engine control
systems. When these systems are operating properly,
your vehicle will provide excellent performance and fuel
economy, as well as engine emissions well within current
government regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
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.
134 MAINTAINING YOUR VEHICLE

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturers specifica-
tions, should be obtained immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected for prolonged period.
