MAINTAINING YOUR VEHICLE
ONBOARD DIAGNOSTIC
SYSTEM — OBD II
Your vehicle is equipped with a sophisti-
cated onboard diagnostic system called
OBD II. This system monitors the perfor-
mance of the emissions, engine, and au-
tomatic transmission control systems.
When these systems are operating prop-
erly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current gov-
ernment 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. Although your vehicle will usually
344
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
driveability. 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

If the vehicle diagnostic system deter-
mines that the fuel filler cap is loose,
improperly installed, or damaged, a "gAS-
CAP" message will display in the odom-
eter or a "CHECK GASCAP" message will
be displayed in the Electronic Vehicle In-
formation Center (EVIC). Refer to "Elec-
tronic Vehicle Information Center (EVIC)"
in "Understanding Your Instrument Panel"
for further information. Tighten the gas
cap until a clicking sound is heard. This
is an indication that the gas cap is prop-
erly 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 problem is detected
