Maintenance and care Running out of fuel Avoid running out fuel because this situation may have an adverse affect on powertrain components. If you have run out of fuel: • You may need to crank the engine several times before the system starts to pump fuel from the tank to the engine. • Your "Check Engine" light may come on. For more information on the "Check Engine" light, refer to the Instrumentation chapter. Fuel Filler Cap Your fuel tank filler cap has an indexed design with a one-eighth 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 and reinstall it being careful to align the cap properly. If you must replace the fuel filler cap, replace it with a genuine Ford or Motorcraft part. The customer warranty may be void for any damage to the fuel tank or fuel system if a genuine Ford or Motorcraft fuel filler cap is not used. The fuel system may be under pressure. If the fuel filler cap is venting vapor or if you hear a hissing sound, wait until it stops before completely removing the fuel filler cap. Otherwise, fuel may spray out and injure you or others. 230
