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 trans- mission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as 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. 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 driveability. The vehicle must be serviced before any emissions tests can be performed.
• If the MIL is flashing while the vehicle is running, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic system (OBD II) and a connection port to allow access to information related to the performance of your emissions controls. Authorized service technicians may need to ac- cess this information to assist with the diagnosis and service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should connect equipment to the OBD II connection port in order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD II connection port, such as a driver-behavior tracking device, it may: • Be possible that vehicle systems, including safety related systems, could be impaired or a loss of vehicle control could occur that may result in an accident involving serious injury or death.
• Access, or allow others to access, information stored in your vehicle systems, including personal information.

Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can determine if the fuel filler cap is possibly loose or improp- erly installed. A “gASCAP” message will be displayed in the instrument cluster. Tighten the gas cap until a “click- ing” sound is heard. This is an indication that the gas cap is properly tightened. Push the trip odometer RESET
button to turn off the message. 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 twice in a row, the system will turn on the MIL. Resolving the problem will turn the MIL light off.
