2008 DODGE AVENGER catalytic converter

could lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
26. Anti-Lock Warning Light (ABS)
This light monitors the ABS. 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 ABS warning light should be checked frequently to
assure that it is operating properly. Turn the ignition key
to the on position, but do not start the vehicle. The light
should come on. If the light does not come on, have the
system checked by an authorized dealer.
27. High Beam Indicator
This light shows that the headlights are on high
beam. Push the turn signal lever away from the
steering wheel to switch the headlights from high or low
beam.
28. Brake System Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system (if equipped). UNDERSTANDING YOUR INSTRUMENT PANEL 179

Normal Starting
Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator pedal.
Simply turn the ignition switch to the START position
and release when the engine starts. If the engine fails to
start within 15 seconds, turn the ignition switch to the
LOCK position, 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. Vehicles equipped with an automatic trans-
axle cannot be started this way. 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 improp-
erly, so follow the procedure carefully. See section 6
of this manual for jump starting instructions.
Tip Start Ð Automatic Transaxle Only
Do not press the accelerator. Turn the ignition key briefly
to START position, and release it. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running.262 STARTING AND OPERATING

² An 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 authorized dealer for service assistance.
² The use of fuel additives, which are now being sold as
octane enhancers, is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you. CARBON MONOXIDE WARNINGS
WARNING!Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
² Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle. STARTING AND OPERATING 323

11. Check the tire pressure as soon as possible. Correct
pressure as required.
JUMP-STARTING PROCEDURES DUE TO A LOW
BATTERY
Jump-starting remote battery terminals are located under
the hood.
The battery is stored between the left front headlight
assembly and the left front wheel splash shield. Access is
through the splash shield. WARNING! ² 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.
² Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transaxle
cannot be started this way. 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.
² Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
² During cold weather when temperatures are below
freezing point, electrolyte in a discharged battery may
freeze. Do not attempt jump-starting because the battery
could rupture or explode. The battery temperature must
be brought up above freezing point before attempting
jump-start.358 WHAT TO DO IN EMERGENCIES

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, engine, and automatic
transaxle control systems. When these systems are oper-
ating properly, your vehicle will provide excellent per-
formance and fuel economy, as well as maintaining
engine emissions well within current government regu-
lations.
If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator
Light (MIL). It will also store diagnostic codes
and other information to assist an authorized service
technician in making repairs. Although your vehicle will
usually be drivable and not need towing, see your
authorized dealer for service as soon as possible. CAUTION!² Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
² If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
LOOSE FUEL FILLER CAP MESSAGE
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose or
improperly installed. A ªgASCAPº message will be dis-
played in the instrument cluster. Tighten the gas cap until
a 9 clicking 9 sound is heard. This is an indication that the
gas cap is properly tightened. Press the Trip Odometer MAINTAINING YOUR VEHICLE 371

SPARK PLUGS
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to ªFluids, Lubricants, and Genuine Partsº in
this section for the proper type of spark plug for use in
your vehicle.
ENGINE AIR CLEANER FILTER
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for engine air cleaner filter maintenance inter-
vals.
NOTE: Be sure to follow the ªdusty or off-road condi-
tionsº maintenance interval if applicable. WARNING!The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
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. MAINTAINING YOUR VEHICLE 379
7

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. NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
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 exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything 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 manufacturer's specifica-
tions, should be obtained immediately.380 MAINTAINING YOUR VEHICLE
