2004 CHRYSLER CONCORDE fuel

unleaded gasoline having lower sulfur to determine if the
problem is fuel related prior to returning your vehicle to
an authorized dealer for service.
CAUTION!
If the Malfunction Indicator Light is flashing, imme-
diate service is required. See the On Board Diagnos-
tics paragraph in the Maintenance section of this
manual.
Adding Fuel
NOTE:
The fuel tank filler tube has a restricting door
about 2 inches (50 mm) down from the opening. If fuel is
poured from a portable container, the container should
have a flexible nozzle long enough to force open the
restricting door.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
NOTE:Tighten the gas cap until you hear a “clicking”
sound. This is an indication that the gas cap is properly
tightened.
The Malfunction Indicator light will come on if the gas
cap is not properly secured. Make sure that the gas cap
is tightened each time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
170 STARTING AND OPERATING

Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door, on the driver’s
side of the vehicle. If the gas cap is lost or damaged, be
sure the replacement cap is for use with this vehicle.
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system. The Mal-
function Indicator light will come on if the gas cap is
not properly secured.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This system
monitors the performance of the emissions, engine, and
automatic transaxle control systems. When these systems
are operating properly, your vehicle will provide excel-
lent performance and fuel economy, as well as engine
emissions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator or Service Engine
Soon Light. It will also store diagnostic codes and other
information to assist your service technician in making
repairs. Although your vehicle will usually be driveable
and not need towing, see your dealer for service as soon
as possible.CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.
If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
If the gas cap is not tightened properly, the light may
come on. Be sure the gas cap is tightened every time you
add fuel. Tighten the cap until you hear it “click.”

WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain the maintenance service
recommended by the engineers who designed your ve-
hicle.
Besides the maintenance items for which there are fixed
maintenance internals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained, at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
2.7L Engine Oil Dipstick
194 MAINTAINING YOUR VEHICLE

Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed.
•Day or night temperatures are below 32°F (0°C)
•Stop and go driving
•Extensive engine idling
•Driving in dusty conditions
•Short trips of less than 10 miles (16.2 km)
•More than 50% of your driving is at sustained high
speeds during hot weather above 90°F (32°C)
•Trailer towing
•Taxi, police, or delivery service (commercial operation)
•Off road or desert operation
•If equipped for and operating with E —85 (ethanol)
fuel
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on scheduleAof theMainte-
nance Schedulessection of this manual.
NOTE:Under no circumstances should oil change
intervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.

The proper SAE viscosity grade of engine oil should be
selected based on the following recommendations and be
within the operating temperature shown in the engine oil
viscosity charts.
SAE 10W-30 engine oil is preferred for use in 3.5L engines
within the operating temperatures shown in the viscosity
chart. SAE 5W-30 engine oil is allowed for use in the 3.5L
engines during cold weather only to improve cold
weather starting.SAE 5W-30 oil is preferred for use in 2.7L engines within
the operating temperatures shown in the viscosity chart.
You are highly encouraged to use SAE 5W-30 oils to aid
in low temperature starting and for improved fuel
economy.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (APIJ) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
