ESP FORD THUNDERBIRD 2002 11.G Owner's Manual

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
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.

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
²When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
compliance certification label). Consult your dealer for specific weight
information.
²The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems - such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
²Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use or are not properly installed. When operated, such systems may
cause the engine to stumble or stall. In addition, such systems may be
damaged or their performance may be affected by operating your
vehicle. If you intend on fitting a mobile radio such as a citizens band
radio (CB), please refer to your local dealer for Ford recommended
installation guidelines. Ask you dealer to reference the ªFord Mobile
Radio Installation Guidelines.º (Citizens band [CB] transceivers, garage
door openers and other transmitters with outputs of five watts or less
will not ordinarily affect your vehicle's operation.)
²Ford cannot assume responsibility for any adverse effects or damage
that may result from the use of such equipment.
