Maintenance and Specifications • Place approved fuel container on the ground. • DO NOT fill a fuel container while it is in the vehicle (including the cargo area). • Keep the fuel pump nozzle in contact with the fuel container while filling. • DO NOT use a device that would hold the fuel pump handle in the fill position. Fuel Filler Cap Your fuel tank filler cap has an indexed design with a 1/4 turn on/off feature. When fueling your vehicle: 1. Turn the engine off. 2. Carefully turn the filler cap counterclockwise 1/4 of a turn to unscrew the cap. 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 until at least one click is heard. 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 start-up 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. Remove fuel filler cap slowly. Otherwise, fuel may spray out and injure you or others. If you do not use the proper fuel filler cap, excessive 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. 249 2005 Mercury Mariner (mrn) Owners Guide (post-2002-fmt) USA_English (fus)
