When replacing full size
tires, never mix radial,
bias-belted, or bias-type tires.
Use only the tire sizes that are
listed on the tire pressure decal.
Make sure that all tires are the
same size, speed rating, and
load-carrying capacity. Use only
the tire combinations
recommended on the decal. If
you do not follow these
precautions, your vehicle may
not drive properly and safely.
Make sure that all
replacement tires are of
the same size, type, load-carrying
capacity and tread design (e.g.,
ªAll Terrainº, etc.), as originally
offered by Ford.
Do not replace your tires
with ªhigh performanceª
tires or larger size tires.
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier to lose control
and roll over.
Identifying tire types
Refer to the Safety Compliance
Certification Label to determine
the specific size tire and wheel
Ford Motor Company recommends
for use on this vehicle.

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.
Follow these guidelines when using
snow tires and chains.
²Use only SAE Class ªSº chains.
²Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
²4x2: Install tire chains on rear
tires (of all sizes) only.
²4x4: Install tire chains on rear
tires (of all sizes), and on front
tires of size P235/70R16 only.
²Drive cautiously. If you hear the
chains rub or bang against your
vehicle, stop and retighten the
chains. If this does not work,
remove the chains to prevent
damage to your vehicle.
²If possible, avoid fully loading
your vehicle.
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.
FUEL
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.
²Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no
symptoms are immediately
apparent. The toxic affects of
fuel may not be visible for
hours.
²Fuels can also be harmful if
absorbed through the skin. If
fuel is splashed on the skin,
promptly remove contaminated
clothing and wash skin
thoroughly with soap and water.
²If fuel is splashed in the eyes,
remove contact lenses, flush
with water for 15 minutes and
seek medical attention.
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. Consult a
physician immediately.
Choosing the right fuel
Use only UNLEADED FUEL. The
use of leaded fuel is prohibited by
law and could damage your

vehicle. The damage may not be
covered by your warranty.
Your vehicle was not designed to
use fuel containing
manganese-based additives such as
MMT. Additionally, vehicles
certified to 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 that
your vehicle was not designed for
may not be covered by your
warranty.
Octane recommendations
Your vehicle is designed to use
regular gasoline with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
ªregularº in high altitude areas that
are sold with octane ratings of 86
or even less.
Do not be concerned if your
vehicle sometimes knocks lightly.
However, if it knocks heavily under
most driving conditions on the
recommended octane fuel, see

your dealer or a qualified service
technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting,
rough idle or hesitation problems
try a different brand of fuel. If the
condition persists, see your dealer
or a qualified service technician.
The American Automobile
Manufacturers Association (AAMA)
issued a gasoline specification to
provide information on high quality
fuels that optimize the
performance of your vehicle. We
recommend the use of gasolines
that meet the AAMA specification
if they are available.
It should not be necessary to add
any aftermarket products to your
fuel tank if you continue to use a
high-quality fuel.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines, that
contain oxygenates such as a
maximum of 10% ethanol or 15%
MTBE. There should be no more
than 5% methanol with cosolvents
and additives to protect the fuel
system.
Calculating fuel economy
To accurately calculate your
vehicle's fuel economy:
1. Fill the tank completely and
record the initial odometer
reading.
com_fuel_quality.01
f12_cleaner_air
f12_calculating_economy
Maintenance and care
192

2. Each time you fill the tank,
record the amount of fuel added
(in liters or gallons).
3. After at least three to five fuel
tank fill-ups, fill the fuel tank and
record the current mileage
reading.
4. Use one of the following
equations to calculate fuel
economy.
Liters used x 1004Total
kilometers traveled = km/liter.
Total miles traveled4Total
gallons used = mpg.
5. Keep a record for at least one
month. This will provide an
accurate estimate of the vehicle's
fuel economy.
