2006 CHRYSLER 300 SRT catalytic converter

and remain on briefly as a bulb check. If the light does
not come on during starting, have the system checked
by an authorized dealer.
21. Voltage Light
This light monitors the electrical system volt-
age. The light should turn on momentarily as
the engine is started. If the light stays on or turns on
while driving, it indicates a problem with the charging
system. Immediate service should be obtained.
22. Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD that monitors engine and
automatic transmission control systems. The
light will illuminate when the key is in the ON
position before engine start. If the bulb 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 244 for more information.)

WARNING!
•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.
•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.
If Engine Fails to Start
If the engine fails to start after you have followed the
“NORMAL STARTING” procedure, it may be flooded.Push the accelerator pedal all the way to the floor and
hold it there while cranking the engine. This should clear
any excess fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been 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 en-
gine.
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.
184 STARTING AND OPERATING

content of gasoline may not be indicated on the pump,
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 levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated 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 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
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
222 STARTING AND OPERATING

WARNING!
•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 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 flam-
mable 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.
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump starting.
NOTE: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).
1. Wear eye protection and remove any metal jewelry
such as watch bands 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 and
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in PARK and turn the
ignition switch to the OFF (or LOCK) position for both
vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.

Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule “A”. If, however, you
drive the vehicle frequently under dusty or severe con-
ditions, the filter element should be inspected periodi-
cally and replaced if necessary at the intervals shown on
Schedule “B”.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner 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 cleaner 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.
MAINTAINING YOUR VEHICLE 251

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 involving
engine misfire or other apparent loss of performance,
have your vehicle serviced promptly. Continued opera-
tion 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 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 indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer’s specifications, should be ob-
tained immediately.
To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
