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 transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions 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
If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a loose gascap indicator will display in the EVIC telltale display area.
Refer to “Electronic Vehicle Information Center (EVIC) in “Understanding Your Instrument Panel” for further in- formation. Tighten the fuel filler cap properly and press
the SELECT button to turn off the message. If the problem continues, the message will appear the next time the vehicle is started. A loose, improperly installed, or damaged fuel filler cap may also turn on the Malfunction Indicator Light (MIL).
