CABIN AIR FILTER
The particulate air filtration system is designed to reduce the
concentration of airborne particles such as dust, spores and pollen in the
air being supplied to the interior of the vehicle. The particulate filtration
system gives the following benefits to customers:
²Improves the customer's driving comfort by reducing particle
concentration
²Improves the interior compartment cleanliness
²Protects the climate control components from particle deposits
The filter is located just in front of the windshield under the cowl grille
on the passenger side of the vehicle.

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.
In cold weather conditions, the wiper blades need to be thawed before
operating in order to prevent premature wear to the wiper blades. Before
operating the wiper blades in cold weather, refer to theElectric window
heaterssection of theControls and Featureschapter.
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.

away from the windshield into the
service position. Turn the blade at
an angle from the wiper arm.
2. Firmly press the release tab to
unlock wiper blade from wiper arm.

221

3. Pull the wiper blade down toward
the windshield to remove it from the
arm.
4. Attach the new wiper to the
wiper arm and reposition the clip
until it locks.
Repeat for driver's side wiper arm.
INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
New vehicles are fitted with tires
that have a rating on them called
Tire Quality Grades. The Quality
grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
²Treadwear 200 Traction AA Temperature A
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 graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
Maintenance and care
222

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 AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. Those
grades represent the tire's ability to stop on wet pavement as measured
under controlled conditions on specified government 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
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
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.
²
Check 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
Certification Label.
Maintenance and care
223

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 Scheduled Maintenance Guide. If you notice
that the tires wear unevenly, have them checked.
²Four tire rotation
²Five tire rotation
(with full-size spare tire)
Maintenance and care
224

²Unidirectional tire rotation
For vehicles equipped with original
equipment unidirectional tires and
full-size spare, your vehicle can be
driven with the unidirectional
full-size spare, rotating counter to
the directional arrow on the tire
sidewall.
Your unidirectional full-size spare
tire is rotated for wear balance. Best
performance may be achieved by
remounting the tire to the wheel, if
necessary, to permit tire rotation
with the directional arrow on the
tire sidewall.
Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification Label. Make sure that all tires are the same size, speed
rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. 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.
Maintenance and care
225

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.
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 or chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
²Use only SAE Class S chains with P215/60R16 tires.
²Do not use tire chains with size P235/50R17 tires. Use of SAE Class S
chains or other chain types may damage your vehicle.
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.
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 or chains.
