5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 16 km (10 miles) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36° C (-34° F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the “cold full” of “cold fill range” level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above

WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
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 cause injury.
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 personal
injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Fuel ethanol and gasoline may contain benzene, which is a
cancer causing agent.
•Shut the engine off and
extinguish all smoking materials
and open flames before fueling.
•Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately.
•Avoid inhaling fuel vapors.
•Avoid getting fuel in your eyes. If fuel is splash in the eyes, remove
contact lenses (if worn), flush with water for 15 minutes and seek
medical attention.
•If fuel is splashed on the skin and/or clothing, promptly remove
contaminated clothing and wash skin thoroughly with soap and water.
•Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram. Breathing fuel vapors or skin contact could cause sickness
or serious personal injury.

The flow of fuel through the fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an
ungrounded fuel container.
To avoid static build-up:
•Place approved fuel container on the ground.
•DO NOT fill a container while it is in the vehicle.
•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.
Unleaded gasoline engines
•Use only unlead fuel.
•Use “Regular” unleaded gasoline
with an (R+M)/2 octane rating of
87.
•Do not use fuel containing
methanol.
•Do not use fuel or fuel additives with metal compounds.
Fuel quality
The World-wide Fuel Charter recommends gasoline specifications to
provide improved performance and emission control system protection.
Ask your fuel supplier about gasolines that meet the World-wide Fuel
Charter.
It should not be necessary to add any aftermarket products to your fuel
tank if you use high quality fuel of the recommended octane rating.
Aftermarket products could cause damage to the fuel system and
invalidate your warranty.
Cleaner air
Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality.
Running out of fuel
Running out of fuel may have an adverse affect on powertrain
components.

•You may need to cycle 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.
•Your “Check Engine” indicator may come on.
Fuel filler cap
When fueling:
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.
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 “Check Fuel Cap” indicator
illuminates and stays on after you
start the engine, the cap may not be
properly installed.
If you must replace the fuel
filler cap, replace it with a fuel filler cap that is designed for your
vehicle.
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 personal
injury.
Fuel filter
Refer to theScheduled Maintenance Guidefor the appropriate
replacement intervals. Replace the fuel filter with an authorized
Motorcraft part.
ESSENTIALS OF GOOD FUEL ECONOMY
We do not recommend taking fuel economy measurements during the
first 1,600 km (1,000 miles) of driving. You will get a more accurate
measurement after 3,000 km - 5,000 km (2,000 miles - 3,000 miles)
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill capacities
section of this chapter.

The advertised capacity is the amount of 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 small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
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 engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
•Use the same filling rate setting (low — medium — high) each time
the tank is filled.
•Allow no more than 2 automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
•Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
•Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the tank and record the odometer reading.
2. Each time you fill up the tank, record the amount of fuel added.
3. After at least 3 fill-ups, fill the fuel tank and record the current
odometer reading.
4. Subtract your initial odometer reading from the current reading.
Use one of the following simple calculations to determine fuel economy:
•Liters x 100total kilometers
•Miles traveledgallons used
Keep a record for at least one month and record the type of driving (city
or highway). You can also keep records in summer and winter to
determine how temperature impacts fuel economy. Note that ethanol
decrease fuel economy.

Improving fuel economy
To improve your fuel economy:
•Do not leave your vehicle idling for long periods of time.
•Drive at a moderate pace, with smooth acceleration and deceleration.
•Turn off speed control in hilly terrain.
•Follow the recommended maintenance schedule in yourScheduled
Maintenance Guide.
•Do not carry unnecessary weight.
EPA window sticker
The EPA window sticker should be your guide for fuel economy
comparisons. If you have any questions about this sticker, contact your
dealer.
EMISSION CONTROL SYSTEM
Your vehicle has emission control components and a catalytic converter
that enable your vehicle to comply with applicable exhaust emission
standards. To make sure that the emission control components work
properly:
•Use only unleaded fuel.
•Avoid running out of fuel.
•Do not turn off your ignition while the vehicle is moving.
•Follow yourScheduled Maintenance Guide.
•Use Ford Motor Company authorized parts for maintenance
replacements or for service.
Consult yourWarranty Guidefor emission warranty information.
Do not park, idle, or drive your vehicle in dry ground cover. The
emission system heats up the engine and exhaust system, which
could cause a fire.
The following signs could indicate a problem with your emission control
system:
•Fluid leaks
•Strange odors
•Smoke

•Loss of engine power
•Illumination of the charging system, temperature, or “Check Engine”
light in the instrument panel.
Exhaust leaks may result in harmful and potentially lethal fumes
entering the passenger compartment.
It is unlawful 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.
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). This OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists the
service technician in properly servicing your vehicle. When theCheck
Engine/Service Engine Soonlight illuminates, the OBD-II system has
detected a malfunction. Temporary malfunctions may cause yourCheck
Engine/Service Engine Soonlight 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.
3. The fuel cap may not have been securely tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly tightening the fuel cap. After three
driving cycles without these or any other temporary malfunctions
present, theCheck Engine/Service Engine Soonlight should turn off.
(A driving cycle consists of a cold engine startup followed by mixed
city/highway driving.) No additional vehicle service is required.
If theCheck Engine/Service Engine Soonlight remains on, have your
vehicle serviced at the first available opportunity.
Readiness for Inspection/Maintenance (I/M) testing
It may be a legal requirement in your area to pass an I/M test of the
on-board diagnostics system. If the system or battery has just been
serviced, the on-board diagnostic system is reset to a “not ready for I/M
test” condition. To ready the system, allow the vehicle to sit for at least
eight hours without starting. Then, start the engine and complete the
following driving cycle:

SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the original tires.
Your tires have all-weather treads to provide traction in the rain and
snow. In some climate, using snow tires or traction devices may be
necessary. For Motor Company offers tire cables as a Ford approved
accessory and recommends use of these or SAE class “S” cables. See
your dealer for more information.
Follow these guidelines:
•Do not use tire cables or chains with P255/70R16 size tires.
•Cables or chains should only be used on the rear wheels.
•If you need to use chains, it is recommended that steel wheels (of the
same size and specification) be used, as chains may chip aluminum
wheels.
•Install cables or chains securely, verifying that they do not touch any
wiring, brake lines or fuel lines.
•Avoid overloading your vehicle.
•Do not use cables or chains on dry roads.
•Do not exceed 48 km/h (30 mph).
•Drive cautiously.
Remove the cables or chains when they are no longer needed.
