22. Oil Pressure LightShows low engine oil pressure. The light will come
on and remain on when the ignition switch is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on during starting, have the system checked by
an authorized dealer.
If the light comes on and remains on while driving, stop
the vehicle and shut off the engine. DO NOT OPERATE
THE VEHICLE UNTIL THE CAUSE IS CORRECTED.
The light does not show the quantity of oil in the engine.
This can be determined using the procedure shown in
Section 7.
23. Airbag Light The light comes on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light does not come on during starting, stays on, or comes on while
driving, have the system checked by an authorized
dealer.

BRAKE SYSTEMYour vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications
with the engine off), the brakes will still function. How-
ever, the effort required to brake the vehicle will be much
greater than that required with the power system oper-
ating.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with some
loss of overall braking effectiveness. This will be evident
by increased pedal travel during application and greater
pedal force required to slow or stop. In addition, if the
malfunction is caused by an internal leak, as the brake
fluid in the master cylinder drops, the brake warning
indicator will light.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. A significant decrease in braking performance or
vehicle stability during braking may occur. It will
take you longer to stop the vehicle or will make your
vehicle harder to control. You could have an accident.
Have the vehicle checked immediately.

Loose Fuel Filler Cap MessageAfter fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A gASCAP message will be dis-
played in the instrument cluster. Tighten the gas cap until
aclicking sound is heard. This is an indication that the
gas cap is properly tightened. Press the odometer reset
button to turn the message off. If the problem persists,
the message will appear the next time the vehicle is
started. This might indicate a damaged cap. If the prob-
lem is detected twice in a row, the system will turn on the
Malfunction Indicator Light (MIL). Resolving the prob-
lem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMSIn 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. 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 the 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 II system is
not readyand you
should notproceed 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 II
system is ready, and you can proceed to the I/M
station.
If your OBD II system is not 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 II
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 II system is
ready or not ready, if the MIL is illuminated during
normal vehicle operation, you should have your vehicle382 MAINTAINING YOUR VEHICLE

MAINTENANCE PROCEDURESThe pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, 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 LevelTo assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to check the engine oil level is about five
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Engine Oil Dipstick
384 MAINTAINING YOUR VEHICLE

Checking the oil while the vehicle is on level ground, will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the
dipstick. Adding one quart of oil when the reading is at
the MIN mark will result in a MAX reading on these
engines.
CAUTION!
Overfilling the crankcase as indicated by an oil level
above the “Max” mark on the engine oil dipstick will
cause oil aeration, which can lead to loss of oil
pressure and an increase in oil temperature. This
could damage your engine.Change Engine OilRoad conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to decide if any apply to you.
•
Day and 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 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 service).
•
Off-Road or desert operation.
•
If equipped for and operating with E-85 (ethanol)
fuel.
NOTE: IfANY of these apply to you then change your
engine oil every 3,000 miles (5 000 km) or three months,

Engine Oil Filter SelectionAll of this manufacturers engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.DRIVE BELTS — CHECK CONDITION AND
TENSIONAt the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, see your authorized dealer for service.Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
SPARK PLUGSSpark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to “Fluids, Lubricants, and Genuine Parts” in
this section for the proper type of spark plug for use in
your vehicle.IGNITION WIRING SYSTEMThe ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Cracked,
damaged, or faulty cables should be replaced.
388 MAINTAINING YOUR VEHICLE

Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.FUEL FILTERA 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 filter replacement may be necessary. The fuel
filters are located inside the fuel tank. See your dealer for
service.AIR CLEANER ELEMENT (AIR FILTER)Under normal driving conditions, replace the filter at the
intervals shown on Schedule “A”. If, however, you drive
the vehicle frequently under dusty or severe conditions,
the filter element should be inspected periodically and
replaced if necessary at the intervals shown on Schedule
“B”.NOTE:
For vehicles with a Turbo engine, a small
amount of oil accumulation in the air cleaner box is
normal. The amount will depend on driving style. The air
cleaner box should be cleaned out and a new make-up-
air filter element should be installed during the normal
air filter maintenance procedure.
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.
