catalytic converter DODGE CHARGER SRT 2008 6.G Owners Manual

The MIL 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 349 for more

If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a 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. 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 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 dan-
gerous if done improperly. Refer to Section 6 for
proper jump-starting procedures and follow them
carefully.If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the normal starting procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15
seconds before trying again.
264 STARTING AND OPERATING

can be used at levels higher than those allowed in the
United States. MMT is prohibited in Federal and Califor-
nia reformulated gasoline.
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 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
and damage the emissions control system.
•An out-of-tune engine or certain fuel or ignition mal-
functions 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 malfunc-
tioning and may require immediate service. Contact
your authorized dealer for service assistance.
•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 the emissions con-
trol system can result in civil penalties being assessed
against you.
STARTING AND OPERATING 323
5

NOTE:
•If a pressure of at least 19 psi (1.3 bar) cannot be
maintained in the tire, the tire is too badly damaged.
Do not attempt to drive the vehicle further. Call for
assistance.
•Do not operate the electric air pump for more than
eight minutes to avoid overheating. The air pump may
be used again once it has cooled down.
•Replace the TIREFIT sealant bottle (5) once every four
years to assure optimum operation of the system.
•If TIREFIT is liquid, clean water and a damp cloth will
remove the material from the vehicle or tire and wheel
components. Once TIREFIT sealing material has dried,
it can easily be peeled off and properly discarded.
•Do not exceed 55 mph (90 km/h) until the tire has
been inspected.
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 dangerous 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 discon-
nected and should only be replaced with a battery of the same type
(vented).

ONBOARD DIAGNOSTIC SYSTEM — 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
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
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 your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the “MIL” on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the

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
authorized 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 emissions 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.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
