2004 CHRYSLER CONCORDE towing

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.”

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.

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to seek service to assure proper catalyst operation
and prevent possible catalyst damage. If the Malfunction
Indicator light is flashing, immediate service is required.
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.
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 suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.

•Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
•If the fluid is hot(180° F / 82° C), the reading should
be in the cross hatched area marked ”HOT” (between
the upper two holes in the dipstick).
•If the fluid is cold(80° F / 27° C), the reading should
be in the cross hatched area marked “COLD” (between
the lower two holes in the dipstick).
•If the fluid level shows low, add sufficient transmis-
sion fluid to bring to the proper level.
CAUTION!
Do not overfill. Dirt and water in the transaxle can
cause serious damage. To prevent dirt and water
from entering the transaxle after checking or replen-
ishing fluid, make certain that the dipstick cap is
seated properly.
Fluid and Filter Changes
Automatic transmission fluid and filter should be
changed as follows:
Maintenance schedule “A”— No change necessary
Maintenance schedule “B”— Every 60,000 miles (96 000
km) change fluid and filter under the following condi-
tions:
•Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is drivenregularlyfor
more than 45 minutes of continuous operation.
NOTE:Refer to Section 8 of this manual for mainte-
nance schedules.
If the transaxle is disassembled for any reason, the fluid
and filter should be changed.
Special Additives
The manufacturer recommends against the addition of
any fluid additives to the transaxle. The only exception to
this policy is the use of special dyes to aid in detecting
fluid leaks. The use of transmission sealers should be
avoided as they may adversely affect seals.

EMISSION CONTROL SYSTEM MAINTENANCE
The “Scheduled” maintenance services, listed inbold
typemust be done at the times or mileages specified to
assure the continued proper functioning of the emission
control system. These, and all other maintenance services
included in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the
emission control devices and systems on your vehicle
may be performed by any automotive repair establish-
ment or individual using any automotive part which has
been certified pursuant to U.S. EPA or, in the State of
California, California Air Resources Board regulations.
