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:
•Treadwear 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
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 climates.
Maintenance and Specifications
232

•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
•The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.

vehicle.
2Rear axle lubricants do not need to be checked or
changed unless a leak is suspected, service is
required or the axle assembly has been submerged
in water. The axle lubricant should be changed any
time the rear axle has been submerged in water. Fill
6 mm to 14 mm (1/4 inch to 9/16 inch) below
bottom of fill hole. Add 118 ml (4 oz.) of Additive

scheduled maintenance guide to determine the
correct service interval.
4Indicates only approximate dry-fill capacity. Some
applications may vary based on cooler size and if
equipped with an in-tank cooler. The amount of
transmission fluid and fluid level should be set by
the indication on the dipstick’s normal operating
range.
5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.

For maximum vehicle performance, keep the
following information in mind when adding
accessories or equipment to your vehicle:
•When 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.
•The 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.
•Mobile 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
or cause the transmission to be damaged or
operate improperly. In addition, such systems may
be damaged or their performance may be affected
by operating your vehicle. (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.)
•Ford cannot assume responsibility for any adverse
effects or damage that may result from the use of
such equipment.
