ONBOARD DIAGNOSTIC SYSTEM — OBD II
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 oper-
ating properly, your vehicle will provide excellent per-
formance 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 Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions
tests can be performed.
•If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose or
improperly installed. A “gASCAP” message will be dis-
played in the instrument cluster. Tighten the gas cap until
aclickingsound is heard. This is an indication that the
gas cap is properly tightened. Press the trip odometer
RESET button to turn off the message. If the problem

EMISSIONS CONTROL SYSTEM MAINTENANCE
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.
Inspection and service should also be done anytime a
malfunction is suspected.
NOTE:Maintenance, replacement or repair of the emis-
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
certified pursuant to U.S. EPA or in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULE
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.
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 necessary.
Based on engine operation condition, 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
and even if the oil change indicator message is NOT
illuminated.
•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 miles (10 000 km) or six months, which-
ever comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If this
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Oil Change
Required” in “Use Factory Settings” of the EVIC sectionin this manual or under “Odometer/Trip Odometer” in
the Instrument Cluster Descriptions section of this
manual.
At Each Stop for Fuel
•Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
