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

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also states the recommended engine oil viscosity
grade for your engine.Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental
additives.
Disposing Of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filtersfrom your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
