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 or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition 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, if the MIL 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 is on with the engine
running.
REPLACEMENT PARTS
Use of genuine MOPAR
parts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.

Engine Oil Filter Selection
All of the manufacturer’s 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. MOPARengine oil filters are high
quality oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
WARNING!
The air cleaner can provide protection in the case of
engine backfire. Do not remove the air cleaner unless
it 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.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR engine air
cleaner filters are a high quality filter and are
recommended.

You will never have to add water, nor is periodic main-
tenance required.

tain lead and lead compounds. Always wash hands

The Scheduled Maintenance services listed inbold type
must be done at the times or mileages specified to ensure
the continued proper functioning of the emissions control
system. These and all other maintenance services in-
cluded 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.

sions control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part that has been

MAINTENANCE SCHEDULE
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Non-EVIC equipped vehicles, “CHAngE OIL” will
flash in the instrument cluster odometer and a single
chime will sound, indicating that an oil change is neces-
sary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).
NOTE:
•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s
oil if it has been six months since your last oil change
even if the oil change indicator message is NOT
illuminated.
