Maintenance and Specifications Fuel filler cap After refueling, if the Check fuel cap 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 securely. The Check fuel cap indicator should turn off after three driving cycles with the fuel filler cap properly installed. A driving cycle consists of a cold engine startĆup followed by mixed city/highway driving. 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. 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. If you do not use the proper fuel filler cap, excessive pressure or vacuum in the fuel tank may damage the fuel system or cause the fuel cap to disengage in a collision, which may result in possible personal injury. Fuel filler cap lock (if equipped) Your vehicle may be equipped with a locking fuel filler cap. When fueling your vehicle: 1. Turn the engine off. 2. Open the fuel filler flap. 3.
