2019 Ford Fusion Owners Manual - Fuel and Refueling

Fuel and Refueling

Follow these guidelines when refueling:

• Extinguish all smoking materials and any open flames before refueling your vehicle.

• Always switch the engine off before refueling.

• Automotive fuels can be harmful or fatal if swallowed. Fuel is highly toxic and if swallowed can cause death or permanent injury. If fuel is swallowed immediately call a physician, even if no symptoms are immediately apparent. The toxic effects of fuel may not be apparent for hours.

• Avoid inhaling fuel vapors. Inhaling fuel vapor can lead to eye and respiratory tract irritation. In severe cases, excessive or prolonged breathing of fuel vapor can cause serious illness and permanent injury.

• Avoid getting fuel in your eyes. If you splash fuel in your eyes, immediately remove contact lenses (if worn), flush with water for 15 minutes and seek medical attention. Failure to seek proper medical attention could lead to permanent injury.

• Fuels can be harmful if absorbed through the skin. If you splash fuel on your skin, clothing or both, promptly remove contaminated clothing and thoroughly wash your skin with soap and water. Repeated or prolonged skin contact causes skin irritation.

• Be particularly careful if you are taking Antabuse or other forms of Disulfiram for the treatment of alcoholism. Breathing fuel vapors could cause an adverse reaction, serious personal injury or sickness. Immediately call a physician if you experience any adverse reactions.

E161513

Your vehicle is designed to operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87.

155

Some fuel stations, particularly those in high altitude areas, offer fuels posted as regular unleaded gasoline with an octane rating below 87. The use of these fuels could result in engine damage that will not be covered by the vehicle warranty.

For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer. See Towing (page 224).

Do not be concerned if the engine sometimes knocks lightly. However, if the engine knocks heavily while using fuel with the recommended octane rating, contact an authorized dealer to prevent any engine damage.

We recommend Top Tier detergent gasolines, where available to help minimize engine deposits and maintain optimal vehicle and engine performance. For additional information, refer to www.toptiergas.com.

Note: Use of any fuel for which the vehicle was not designed can impair the emission control system, cause loss of vehicle performance, and cause damage to the engine which may not be covered by the vehicle Warranty.

Do not use:

• Diesel fuel.

• Fuels containing kerosene or paraffin.

• Fuel containing more than 15% ethanol or E85 fuel.

• Fuels containing methanol.

• Fuels containing metallic-based additives, including manganese-based compounds.

• Fuels containing the octane booster additive, methylcyclopentadienyl manganese tricarbonyl (MMT).

• Leaded fuel, using leaded fuel is prohibited by law.

The use of fuels with metallic compounds such as methylcyclopentadienyl manganese tricarbonyl (commonly known as MMT), which is a manganese-based fuel additive, will impair engine performance and affect the emission control system.

The fuel filler funnel is under the luggage compartment floor covering.

Running out of fuel can cause damage not covered by the vehicle Warranty.

If your vehicle runs out of fuel:

• Add a minimum of 1.3 gal (5 L) of fuel to restart the engine.

• You may need to switch 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. When restarting, cranking time takes a few seconds longer than normal.

Note: If your vehicle is on a steep slope, more fuel may be required.

Use the following guidelines to avoid electrostatic charge build-up, which can produce a spark, when filling an ungrounded fuel container:

• Only use an approved fuel container to transfer fuel to your vehicle. Place the container on the ground when filling it.

• Do not fill a fuel container when it is inside your vehicle (including the cargo area).

• Keep the fuel pump nozzle in contact with the fuel container when filling it.

• Do not use a device that holds the fuel pump nozzle lever in the fill position.

When refueling the vehicle fuel tank from a fuel container, use the fuel filler funnel included with your vehicle. See Fuel Filler Funnel Location (page 156).

Note: Do not use aftermarket funnels as they may not work with the capless fuel system and can damage it.

When refueling the vehicle fuel tank from a fuel container, do the following:

157

Note: Extra funnels can be purchased from an authorized dealer if you choose to dispose of the funnel.

Your vehicle does not have a fuel tank filler cap.

Left-hand side. To open the fuel filler door, press the center rear edge of the fuel filler door and then release.

Right-hand side. To open the fuel filler door, press the center rear edge of the fuel filler door and then release.

5. Operate the fuel pump nozzle within the area shown.

Do not attempt to start the engine if you have filled the fuel tank with incorrect fuel. Incorrect fuel use could cause damage not covered by the vehicle Warranty. Have your vehicle immediately checked.

If the fuel tank filler valve does not fully close, a message could appear in the information display.

If the message appears, do the following:

Note: The message may not immediately reset. If the message continues to appear and a warning lamp illuminates, have your vehicle checked as soon as possible.

FUEL CONSUMPTION

The advertised capacity is the maximum amount of fuel that you can add to the fuel tank after running out of fuel. Included in the advertised capacity is an empty reserve. The empty reserve is an unspecified amount of fuel that remains in the fuel tank when the fuel gauge indicates empty.

Note: The amount of fuel in the empty reserve varies and should not be relied upon to increase driving range.

Your vehicle calculates fuel economy figures through the trip computer average fuel function. See General Information (page 97).

The first 1,000 mi (1,500 km) of driving is the break-in period of the engine. A more accurate measurement is obtained after 2,000 mi (3,000 km).
