WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when
they seem less effective. Substances such as tree sap
and some hot wax treatments used by commercial
car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both
the windshield and wiper blades using undiluted
windshield wiper solution or a mild detergent. Rinse
thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or
other solvents.

Changing the wiper blades
To replace the wiper blades:
1. Pull the wiper arm
away from the
windshield and lock
into the service
position.
2. Turn the blade at an
angle from the wiper
arm. Push the lock pin
manually to release the
blade and pull the
wiper blade down
toward the windshield
to remove it from the arm.
3. Attach the new wiper to the wiper arm and press
it into place until a click is heard.
INFORMATION ABOUT TIRE QUALITY GRADES
New vehicles are fitted
with tires that have
their Tire Quality
Grade (described
below) molded into the
tire's sidewall. These
Tire Quality Grades are
determined by
standards that the
United States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic tires for
use on passenger cars. They do not apply to deep
tread, winter-type snow tires, space-saver or
temporary use spare tires, tires with nominal rim
diameters of 10 to 12 inches or limited production
tires as defined in Title 49 Code of Federal
Regulations Part 575.104(c)(2).

U.S. Department of Transportation-Tire quality
grades:The U.S. Department of Transportation
requires Ford to give you the following information
about tire grades exactly as the government has
written it.
Treadwear
The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under
controlled conditions on a specified government test
course. For example, a tire grade 150 would wear
one and one-half (1 1/2) times as well on the
government course as a tire grade 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may depart
significantly from the norm due to variations in
driving habits, service practices, and differences in
road characteristics and climate.
Traction A B C
The traction grades, from highest to lowest are A, B,
and C, and they represent the tire's ability to stop
on wet pavement as measured under test surfaces of
asphalt and concrete. A tire marked C may have
poor traction performance.
The traction grade assigned to this tire is
based on braking (straight ahead) traction
tests and does not include cornering (turning)
traction.
Maintenance and care
151

Temperature A B C
The temperature grades are A (the highest), B, and
C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of performance on the
laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
SERVICING YOUR TIRES
Checking the tire pressure
²Use an accurate tire pressure gauge.
²Check the tire pressure when tires are cold, after
the vehicle has been parked for at least one hour
or has been driven less than 5 km (3 miles).
²Adjust tire pressure to recommended
specifications found on the tire pressure label
inside the glove compartment door.
Maintenance and care
152

Improperly inflated tires can affect vehicle
handling and can fail suddenly, possibly
resulting in loss of vehicle control.
Tire rotation
Because your vehicle's tires perform different jobs,
they often wear differently. To make sure your tires
wear evenly and last longer, rotate them as indicated
in the ªService Guide.º If you notice that the tires
wear unevenly, have them checked.
²Four tire rotation
Replacing the tires
Replace the tires when
the wear band is
visible through the tire
treads.
Failure to follow these precautions may
adversely affect the handling of the vehicle
and make it easier for the driver to lose control
and roll over.
Maintenance and care
153

Tires that are larger or smaller than your vehicle's
original tires may also affect the accuracy of your
speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade
as the tires you currently have on your
vehicle.
The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and
chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the
same size and specifications as those originally
installed.
Follow these guidelines when using snow tires and
chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Do not use tire chains if your vehicle is equipped
with P225/55ZR16 tires.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.

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 you do not use the proper fuel cap, the
pressure in the fuel tank can damage the
fuel system or cause it to work improperly in a
collision.
The fuel system may be under pressure. If
the fuel cap is venting vapor or if you hear a
hissing sound, wait until it stops before completely
removing the cap.
Automotive fuels can cause serious injury or
death if misused or mishandled.
Observe the following guidelines when handling
automotive fuel:
²Extinguish all
smoking materials
and any open flames
before fueling your
vehicle.
²Always turn off the
vehicle before
fueling.
Maintenance and care
155

²Automotive fuels can be harmful or fatal if
swallowed. Fuel such as gasoline is highly toxic
and if swallowed can cause death or permanent
injury. If fuel is swallowed, call a physician
immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be
visible for hours.
²Avoid inhaling fuel vapors. Inhaling too much fuel
vapor of any kind 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.
²Avoid getting fuel liquid in your eyes. If fuel is
splashed in the eyes, 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.
²Fuels can also be harmful if absorbed through the
skin. If fuel is splashed on the skin and/or
clothing, promptly remove contaminated clothing
and wash skin thoroughly with soap and water.
Repeated or prolonged skin contact with fuel
liquid or vapor causes skin irritation.
²Be particularly careful if you are taking
ªAntabuseº or other forms of disulfiram for the
treatment of alcoholism. Breathing gasoline
vapors, or skin contact could cause an adverse
reaction. In sensitive individuals, serious personal
injury or sickness may result. If fuel is splashed
on the skin, promptly wash skin thoroughly with
soap and water. Consult a physician immediately
if you experience an adverse reaction.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a one-eighth turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
Maintenance and care
156

2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
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 1/8 of a turn until it
stops.
If the ªService Engine Soon/Check Engine ª 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 and
reinstall it being careful to align the cap properly.
If you must replace the fuel filler cap, replace
it with an authorized Motorcraft part. The
customer warranty may be void for any damage
to the fuel tank or fuel system if an authorized
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,
the pressure in the fuel tank can damage
the fuel system or cause it to work improperly in a
collision.
Maintenance and care
157

Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
Your vehicle was not designed to use fuel or fuel
additives with metallic compounds, including
manganese-based compounds containing (MMT).
Vehicles certified to meet California emission
standards (indicated on the underhood Vehicle
Emissions Control Information label) are designed to
operate on California reformulated gasolines. If
California reformulated gasoline is not available
when you refuel, your vehicle can be operated on
non-California fuels. However, even though your
engine will perform adequately on other gasolines,
the performance of the emission control devices and
systems may be adversely affected.
Repair of damage caused by using a fuel for which
your vehicle was not designed may not be covered
by your warranty.
Octane recommendations
3.0L V6 Vulcan and Duratec engines
Your vehicle is
designed to use
ªRegularº unleaded
gasoline with an
(R+M)/2 octane rating of 87. We do not recommend
the use of gasolines labeled as ªRegularº that are
sold with octane ratings of 86 or lower in high
altitude areas.
Do not be concerned if your engine sometimes
knocks lightly. However, if it knocks heavily under
most driving conditions while you are using fuel with
the recommended octane rating, see your dealer or
a qualified service technician to prevent any engine
damage.
