2004 DODGE INTREPID maintenance

Rotate your tires at intervals shown on the maintenance
schedules. More frequent rotation is permissible if de-
sired. The reasons for any rapid or unusual wear should
be corrected before rotating.
The suggested rotation method is the “forward-cross”
shown in the diagram.
Alignment And Balance
The suspension components of your vehicle should be
inspected and aligned when needed to obtain full tire
tread mileage.
Poor suspension alignment may result in:
•fast tire wear;
•uneven tire wear, such as feathering and one-sided
wear;
•vehicle pull to right or left.
Tires may also cause vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
Improper alignment will not cause vehicle vibration.
Vehicle vibration may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.
FUEL REQUIREMENTS
Your engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high quality regular unleaded gasoline
having an octane rating of 87. The use of
premium gasoline is not recommended.
The use of premium gasoline will provide no benefit over
high quality regular and mid-grade gasolines, and in
some circumstances may result in poorer performance.

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.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in additional cost. Therefore
you should not have to add anything to the fuel.
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.
146 STARTING AND OPERATING

NOTE:Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transaxle life by reducing excessive
shifting and heat build up.
•For vehicles equipped with autostick, by using the
autostick mode, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose “4” if the desired
speed can be maintained. Choose “3” or “2” if needed
to maintain the desired speed.
•Extended driving at high RPMs should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPMs.
•Return to a higher gear range or vehicle speed when
road conditions and RPM level allow.
•The trailer tongue load must be considered as part of
the tow vehicle load capacity when loading the ve-
hicle.
•If the trailer weighs more than 1,000 lbs. (450 kg), it
should have its own brakes.
WARNING!
Connecting trailer brakes to your vehicle’s hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
•Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
recommended for motoring safety.
•The automatic transmission fluid, filter, and hypoid
differential fluid should be changed per Maintenance
Schedule “B” if you tow a trailer.
•If your Engine Coolant Light comes on, see the para-
graph on Overheating in Section 6 of this manual.
NOTE:Check the automatic transmission fluid level
before all towing. Fluid discoloration, or a burnt odor,
shows the need for a transmission fluid and filter change.

the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “H”, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, turn the engine off immediately, and call for
service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.

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 which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD 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 system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off
the ignition key or start the engine. This means that
your vehicle’s OBD system isnot readyand you
shouldnotproceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or
start the engine. This means that your vehicle’s OBD
system isreadyand you can proceed to the I/M
station.
170 MAINTAINING YOUR VEHICLE

If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.REPLACEMENT PARTS
Use of genuine Moparparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Moparparts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
DEALER SERVICE
Your dealer has the qualified service personnel, special
tools and equipment to perform all service operations in
an expert manner. Service Manuals are available which
include detailed service information for your vehicle.
Refer to these manuals before attempting any procedure
yourself.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
