IMPORTANT TIRE
MAINTENANCE INFORMATION
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.
Warning: The traction grade
assigned to this tire is based on
braking (straightahead) traction
tests and does not include
cornering (turning) traction.
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
com_traction_abc.01
com_temperature_abc.01
Maintenance and care
183

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.
Checking the tire pressure
Check the tire pressure
periodically and inflate tires as
necessary. To check the tire
pressure, insert the tire pressure
gauge into the valve system.
The cold pressure amount is listed
on the Safety Compliance
Certification label.
Improperly inflated tires
can affect vehicle handling
and can fail suddenly, possibly
resulting in loss of vehicle
control.
Rotating the tires
Rotate your tires at regular
intervals for even wear. Rotation
intervals are listed in the ªService
Guideº.

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.

Maintenance and care
185

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.
Your vehicle requires the use of
the following tire types:
²A/S BSW P255/70R 16
²A/T OWL P255/70R 16
²A/T OWL P265/70R 17
Maintenance and care
186

Ford recommends only tires of this
type and size for your vehicle.
When purchasing replacement tires
for your vehicle, consult your
dealer or qualified service
technician to ensure that the
correct tire types are used.
Using snow tires and traction
devices
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have
allÐweather treads to provide
traction in rain and snow. However,
in some climates, using snow tires
and traction devices may be
necessary. Ford offers tire cables
as a Ford approved accessory and
recommends use of these or their
equivalents. See your dealer or
qualified service technician for
more information on tire cables for
your vehicle. Follow these
guidelines when using snow tires
and traction devices:

Maintenance and care
187

²Install cables securely, verifying
that the cables do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the
cables rub or bang against the
vehicle, stop and retighten
them. If this does not work,
remove the cables to prevent
vehicle damage.
²Avoid overloading your vehicle.
²Remove the tire cables when
they are no longer needed.
²Do not use cables on dry roads.
²The suspension insulation and
bumpers will help prevent
vehicle damage. Do not remove
these components from the
vehicle when using snow tires
and traction devices.
²Do not exceed 48 km/h (30
mph) with tire cables on your
vehicle.
Consult your dealer for information
on other Ford approved methods
of traction control.
FUEL INFORMATION
The ignition key must be turned to
3 (Off) or 1 (Acc) during refueling
to obtain accurate fuel gauge
ratings.

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
com_choosing_fuel.01
Maintenance and care
190

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.
