catalytic converter DODGE MAGNUM 2007 1.G Owners Manual

23. Anti-Lock Brake Light — If Equipped
This light monitors the Anti-Lock Brake System.
The light will turn on when the ignition switch
is turned to the ON position and may stay on for as
long as four seconds.
If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if 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 benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer. (See page 226 for
more information.)
24. Low Fuel Indicator Light
This light will turn on and a single chime will
sound when the fuel level drops to 1/8 tank. (See
page 265 for more information.)25. Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD. The OBD system monitors
engine and automatic transmission control sys-
tems. The light will turn on when the key is in the ON
position before engine start. If the light does not come
on when turning the key from OFF to ON, 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.
The Malfunction Indicator Light flashes to alert you to
serious conditions 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. (See
page 306 for more information.)

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.
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Un-
burned fuel could enter the catalytic converter and
once the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be
dangerous if done improperly. See section 6 of
this manual for the proper jump-starting proce-
dures and follow them carefully.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the key is
released. If this occurs, continue cranking up to 15
seconds with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the key once
the engine is running smoothly. Do not overspeed the
engine.
If the engine shows no sign of starting after two 15-
second periods of cranking with the accelerator pedal
held to the floor, the “NORMAL STARTING” procedure
should be repeated.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
210 STARTING AND OPERATING

Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of Metha-
nol.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles. The manufacturer recom-
mends using gasolines without MMT. Since the MMT
content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer if 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.
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 are not needed under
normal conditions and they would result in additional
cost. Therefore, you should not have to add anything to
the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
•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

JUMP-STARTING PROCEDURES
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.
•Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission 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 danger-
ous if done improperly, so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin, or clothing. Don’t lean
over battery when attaching clamps or allow the clamps to
touch each other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large quantities of
water.
•A battery generates hydrogen gas, which is flammable and
explosive. Keep flame or spark away from the vent holes.
•Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
•The battery in this vehicle has a vent hose that should not
be disconnected and should only be replaced with a battery
of the same type (vented).
NOTE:The battery is stored under a hinged access
cover in the load floor in the cargo area. Remote battery
terminals are located in the engine compartment for
jump-starting.
1. Wear eye protection and remove any metal jewelry
such as watchbands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach, but
do not allow the vehicles to touch one another.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.

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.
Fuel Filter
A plugged fuel filter can cause stalling, limit the speed at
which a vehicle can be driven or cause hard starting.
Should an excessive amount of dirt accumulate in the
fuel tank, filter replacement may be necessary. See your
local dealer for service.
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.
