2008 CHRYSLER 300 catalytic converter

driving, turn off some of the vehicle’s non-essential
electrical devices (i.e. radio) or slightly increase engine
speed (if at idle). If the light remains on, it means that the
charging system is experiencing a problem. See your
local authorized dealer to obtain SERVICE IMMEDI-
ATELY.
24. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD. The OBD system monitors engine
and automatic transmission control systems. 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 lightstays 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 417 for more information.)
25. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle, and shut off the engine as soon as possible. A
single chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked using the procedure
shown in section 7. (See page 421 for more information.)
212 UNDERSTANDING YOUR INSTRUMENT PANEL

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 of
this manual 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.
302 STARTING AND OPERATING

•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.
•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:
•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.
368 STARTING AND OPERATING

correct tightness of each lug nut is 100 ft/lb. (135 N. m).
If in doubt about the correct tightness, have them
checked with a torque wrench by your dealer or at a
service station.
7. For vehicles equipped with center caps, install the
center cap by hand. Do not use a hammer or excessive
force to install the center cap.
8. Stow the jack, tools, and spare tire. Make sure the base
of the jack faces the rear of the vehicle before tightening
down the fastener.
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.
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 explo-
sive. 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).

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