WIPER BLADES
Check the windshield wiper blades
at least twice a year or whenever
the wipers seem less effective than
usual. Substances such as tree sap
and some hot wax treatments used
by commercial car washes can
reduce the effectiveness of wiper
blades.
To make reaching the wiper blades
easy, simply turn the ignition to
the ON position and turn the
wipers on. Wait for the wipers to
reach a vertical position and turn

the ignition to the LOCK position.
Do not move the wipers manually
across the windshield as this may
cause damage to the wiper system.
Inspect the wiper arm pivots on a
regular basis to ensure the wiper
arms move freely. Lubricate the
pivot points as necessary.
Replacing wiper blades
If the wiper blades do not work
properly after cleaning,
replacement of the blade assembly
or the blade element may be
necessary.
To replace the wiper blades:
1. Pull the wiper arm away from
the windshield and lock it into the
service position.
2. Turn the blade at an angle from
the wiper arm. Depress the lock
tab to release the wiper 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.
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
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
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 theService
Guide.

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 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.
When purchasing replacement tires
for your vehicle, consult your
dealer or qualified service
technician to ensure that the
correct tire types are used.
