2010 CHRYSLER 300 check engine light

23. Charging System LightThis light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first placed in the RUN position and
remain on briefly as a bulb check. If the light stays on or
comes on while driving, turn off some of the vehicle’s
non-essential electrical devices or increase engine speed
(if at idle). If the charging system light remains on, it
means that the vehicle is experiencing a problem with the
charging system. Obtain SERVICE IMMEDIATELY. See
an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
24. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when the ignition is placed in the RUN position before engine
start. If the MIL does not come on when turning the
ignition from the OFF to RUN position, have the condi-
tion checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
25. Oil Pressure Warning Light This light indicates 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 indicate how much oil is in the engine.
The engine oil level must be checked using the procedure
shown in “Maintaining Your Vehicle”.
26. Door Ajar Indicator

306 STARTING AND OPERATING

Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, PARK,
REVERSE, and NEUTRAL will continue to operate. Sec-
ond gear will operate in the DRIVE position. The Mal-
function Indicator Light (MIL) may be illuminated.
If the problem has been momentary, the transmission can
be reset to regain all forward gears. To reset the trans-
mission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.3. Turn the engine off.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the shift lever to the desired range. If the
problem is no longer detected, the transmission will
return to normal operation.
If the transmission cannot be reset, see your authorized
dealer.
NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
Have the transmission checked at your authorized dealer
as soon as possible.

apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
MULTI-DISPLACEMENT SYSTEM (MDS) (IF
EQUIPPED) – 5.7L ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:
The MDS system may take some time to return
to full functionality after a battery disconnect.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK position.

switch. Once the situation requiring “Partial Off” mode is
overcome, turn the ESP on again by momentarily press-
ing the ESP OFF switch. This may be done while the
vehicle is in motion.
Synchronizing ESP
The Malfunction Indicator Light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the “ESP/BAS Malfunction Indi-
cator Light” may illuminate with the engine running. If
this should occur, turn the steering wheel completely to
the left and then to the right. The “ESP/BAS Malfunction
Indicator Light” should go out. However, if the light
remains on, have the ESP and BAS checked at your
authorized dealer as soon as possible.
ESP/BAS Malfunction Indicator Light and
ESP/TCS Indicator Light
The Malfunction Indicator Light for the ESP is
combined with the BAS indicator. The “ESP/
BAS Malfunction Indicator Light” and the
“ESP/TCS Indicator Light” in the instrument
cluster both come on when the ignition switch is turned
to the ON position. They should go out with the engine
running.
The system will turn the “ESP/BAS Malfunction Indica-
tor Light” on continuously while the engine running if it
detects a malfunction in either the ESP or the BAS or
both. If the light remains on after several ignition switch
cycles, and you have driven the vehicle several miles
(kilometers) at speeds greater than 30 mph (48 km/h),
and the ESP is synchronized (refer to Synchronizing ESP),
see your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
344 STARTING AND OPERATING

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
”gASCAP” message will appear in the odometer or 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
426 MAINTAINING YOUR VEHICLE

TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.
4. Approximately 15 seconds later, one of two things will
happen:
