Maintenance and Specifications immediately. It may take several driving cycles for the Check Fuel Fill Inlet lamp or Check Fuel Fill Inlet message to turn off. A driving cycle consists of an engine start-up (after four or more hours with the engine off) followed by city/highway driving. Continuing to drive with the Check Fuel Fill Inlet lamp or Check Fuel Fill Inlet message on may cause the Service Engine Soon lamp to turn on as well. WARNING: The fuel system may be under pressure. If you hear a hissing sound near the fuel filler door (Easy Fuel™ "no cap" fuel system), do not refuel until the sound stops. Otherwise, fuel may spray out, which could cause serious personal injury.

The use of leaded fuel is prohibited by law and could damage your vehicle. Your vehicle was not designed to use fuel or fuel additives with metallic compounds, including manganese-based additives. Note: Use of any fuel other than those recommended may cause powertrain damage, a loss of vehicle performance, and repairs may not be covered under warranty.
