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 maintaining
engine emissions well within current government regu-
lations.
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 an authorized service
technician in making repairs. Although 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
a ЉclickingЉ sound is heard. This is an indication that the
gas cap is properly tightened. Press the Trip Odometer
