Non-Flex Fuel Vehicles (FFV) are compatible with gasoline containing up to 15% ethanol (E-15). Gasoline with higher ethanol content may void the New Vehicle Limited Warranty.

•  Operate in a lean mode.
•  OBD II "Malfunction Indicator Light" on.
•  Poor engine performance.
•  Poor cold start and cold drivability.
•  Increased risk for fuel system component corrosion
