Refilling With a Portable Fuel Container
WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy Fuel® system. This could
damage the fuel system and its seal, and may cause fuel to run onto the
ground instead of filling the tank, which could result in serious personal
injury.
WARNING: Do not try to pry open or push open the Easy Fuel®
system with foreign objects. This could damage the fuel system
and its seal and cause injury to you or others.
With the Easy Fuel® “no cap” fuel system, use the following directions
when filling from a portable fuel container:
When filling the vehicle’s fuel tank from a portable fuel container, use the
funnel included with the vehicle. 1. The white plastic funnel is located under the
spare tire tool panel located in the floor
compartment behind the rear seat.
2. Unlatch and remove the spare tire tool panel. Remove the white
plastic funnel.
3. Slowly insert the funnel into the Easy Fuel system.
4. Fill the vehicle with fuel from the portable fuel container.
5. Clean the funnel or properly dispose of it. Extra funnels can be
purchased from your authorized dealer if you choose to dispose of the
funnel. Do not use aftermarket funnels; they will not work and can
damage the Easy Fuel system. The included funnel has been specially
designed to work safely with your vehicle.

REFUELING
WARNING:Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
• Read and follow all the instructions on the pump island.
• Turn off your engine when you are refueling.
• Do not smoke if you are near fuel or refueling your vehicle.
• Keep sparks, flames and smoking materials away from fuel.
• Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
• Keep children away from the fuel pump; never let children pump
fuel.
• Do not use personal electronic devices while refueling.
WARNING: Stop refueling after the fuel pump nozzle
automatically shuts off for the second time. Failure to follow this
will fill the expansion space in the fuel tank and could lead to fuel
overflowing.
Note: Wait at least 10 seconds before removing the fuel pump nozzle to
allow any residual fuel to drain into the fuel tank.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
• 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.
Easy Fuel® “No Cap” Fuel System
WARNING: The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door, do not refuel until the
sound stops. Otherwise, fuel may spray out, which could cause serious
personal injury.

FUEL CONSUMPTION
Filling the Tank
The advertised capacity is the indicated capacity and the empty reserve
combined. Indicated capacity is the difference in the amount of fuel in a
full tank and a tank when the fuel gauge indicates empty. Empty reserve
is the amount of fuel in the tank after the fuel gauge indicates empty.
Note:The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your vehicle
after the fuel gauge indicates empty, you might not be able to refuel the
full amount of the advertised capacity of the fuel tank due to the empty
reserve still present in the tank.
For consistent results when filling the fuel tank:
• Turn the ignition off before fueling; an inaccurate reading results if the
engine is left running.
• Use the same fill rate (low–medium–high) each time the tank is filled.
• Allow no more than two automatic click–offs when filling.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles (1600 kilometers)
of driving (this is your engine’s break-in period); a more accurate
measurement is obtained after 2000 miles–3000 miles (3200
kilometers–4800 kilometers). Also, fuel expense, frequency of fill-ups or
fuel gauge readings are not accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Calculate fuel economy as follows:
Standard: Divide miles traveled by gallons used.
Metric: Multiply liters used by 100, then divide by kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter show how temperature impacts fuel economy.
In general, lower temperatures mean lower fuel economy.

sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult your warranty information for complete emission warranty
information.
On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle.When the service engine soon indicator illuminates, the OBD-II
system has detected a malfunction. Temporary malfunctions
may cause the service engine soon indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. See Easy Fuel®
No Cap Fuel System in this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly closing the fuel fill inlet or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon indicator
should stay off the next time the engine is started. A driving cycle
consists of a cold engine start-up followed by mixed city or highway
driving. No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon indicator on can result in
increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and can lead to more costly repairs.

capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Tire Label or Safety Compliance Certification Label:
Base Curb Weight– is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight – is the weight of your new vehicle when you
picked it up from your authorized dealer plus any aftermarket
equipment.
Payload – is the combined weight of cargo and passengers that the
vehicle is carrying. The maximum payload for your vehicle can be found
on the Tire Label on the B-Pillar or the edge of the driver’s door
(vehicles exported outside the US and Canada may not have a Tire
Label). Look for “THE COMBINED WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.” for
maximum payload. The payload listed on the Tire Label is the maximum
payload for the vehicle as built by the assembly plant. If any aftermarket
or authorized-dealer installed equipment has been installed on the
vehicle, the weight of the equipment must be subtracted from the
payload listed on the Tire Label in order to determine the new payload.
WARNING: The appropriate loading capacity of your vehicle can
be limited either by volume capacity (how much space is
available) or by payload capacity (how much weight the vehicle should
carry). Once you have reached the maximum payload of your vehicle,
do not add more cargo, even if there is space available. Overloading or
improperly loading your vehicle can contribute to loss of vehicle control
and vehicle rollover.

Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine and
emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Check the engine oil level.
2. If the engine oil level is not within the normal range, add engine oil
that meets Ford specifications. See Capacities and Specificationsfor
more information. Remove the engine oil filler cap and use a funnel to
pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level dipstick.
4. Install the dipstick and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks are heard or until the cap is fully seated.
ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the concentration and level of the engine
coolant at the intervals listed in the Scheduled Maintenance
Information.
Note: Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note: If the level is at the MIN mark, below the MIN mark, or empty,
add coolant immediately. See Adding Engine Coolantin this chapter.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
