2004 CHRYSLER CONCORDE service interval

Airbag Light
You will want to have the airbags ready for your
protection in an impact. While the airbag system
is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the
system immediately.
•The AIRBAG light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
•The light remains on or flickers after the 6 to 8 second
interval.
•The light flickers or comes on and remains on while
driving.
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time– babies and children too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.Children 12 years and under should ride properly buck-
led up in a rear seat. According to crash statistics,
children are safer when properly restrained in the rear
seat rather than the front.
WARNING!
In a collision, an unrestrained child, even a tiny
baby, can become a missile inside the vehicle. The
force required to hold even an infant on your lap
could become so great that you could not hold the
child, no matter how strong you are. The child and
others could be badly injured. Any child riding in
your vehicle should be in a proper restraint for the
child’s size.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat owner’s manual to ensure you have the right seat for
your child. Use the restraint that is correct for your child:

exiting the vehicle, to have the headlamps remain on for
30, 60, or 90 seconds, or not remain on. Pressing the STEP
button when in this display will select 30, 60, 90, or OFF.
Headlamp On With Wipers (Available with Auto
Headlights Only)
When this feature is selected and the headlight switch
has at least once been moved to the AUTO position, the
headlights will turn on when the wipers are turned on.
The headlights will also turn off when the wipers are
turned off if they were turned on in this way. Pressing the
STEP button when in this display will select “Yes” or
“No.”
NOTE:Turning the headlights on during the daytime
causes the instrument panel lights to dim. To increase the
brightness, refer to “Lights” in this section.
Service Interval
When this feature is selected a service interval between
2,000 (3 200 km) and 6,000 miles (9 600 km) in 500 mile
(800 km) increments may be selected. Pressing the STEP
button when in this display will select distances between
2,000 (3 200 km) and 6,000 miles (9 600 km) in 500 mile
(800 km) increments.
Reset Service Distance (Displays Only if Service
Interval was Changed)
When this feature is selected the current accumulated
service distance can be reset to the newly selected service
interval. Pressing the STEP button when in this display
will select “Yes” or “No.”
Easy Exit Seat
When this feature is selected the driver’s seat moves
rearward two inches (55 mm) or to the farthest rearward
position if this distance is less than two inches (55 mm)
when the key is removed from the ignition switch so that
the driver can more easily exit the vehicle. The seat will
return to the memorized seat location (if REMOTE LINK
TO MEMORY is set to YES) when the remote keyless
entry transmitter is used to unlock the door. Pressing the

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.

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.

Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent replacement of the fuel filter which is mounted
in the fuel tank may be necessary. See your dealer for
service.
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.
202 MAINTAINING YOUR VEHICLE

•Maintain coolant concentration of a minimum of 50%
ethylene glycol and high quality water with recom-
mended antifreeze for proper corrosion protection of
your engine cooling system that contains aluminum
components.
•Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
•Keep the front of the radiator and air conditioning
condenser clean.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in Section 8.
