Maintenance and care your fuel supplier about gasolines that meet the World-wide Fuel Charter. Cleaner air Ford approves the use of reformulated "cleaner-burning" gasolines to improve air quality. These gasolines may contain oxygenates up to 10% ethanol or 15% MTBE. Running out of fuel Avoid running out of fuel because this situation may have an adverse affect on powertrain components. If you have run out of fuel: • You may need to cycle the ignition from OFF to ON several times after refueling, to allow the fuel system to pump the fuel from the tank to the engine. • Your "Check Engine" indicator may come on. For more information on the "Check Engine" indicator, refer to the Instrumentation chapter. Fuel Filler Cap Your fuel tank filler cap has an indexed design with a 1/8 turn on/off feature. When fueling your vehicle: 1. Turn the engine off. 2. Carefully turn the filler cap counterclockwise 1/8 of a turn until it stops. 3. Pull to remove the cap from the fuel filler pipe. 4. To install the cap, align the tabs on the cap with the notches on the filler pipe. 5. Turn the filler cap clockwise 1/8 of a turn until it stops. If the "Service Engine Soon/Check Engine" indicator comes on and stays on when you start the engine, the fuel filler cap may not be properly installed. Turn off the engine, remove the fuel filler cap, align the cap properly and reinstall it. If you must replace the fuel filler cap, replace it with a fuel filler cap that is designed for your vehicle. The customer warranty may be void for any damage to the fuel tank or fuel system if the correct genuine Ford or Motorcraft fuel filler cap is not used. 220
