If you believe that your vehicle
has a defect which could cause a
crash or could cause injury or
death, you should immediately in-
form the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Toyota Motor
Sales, U.S.A., Inc.
(Tollfree: 18003314331).
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of ve-
hicles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved
in individual problems between
you, your dealer, or Toyota Motor
Sales, U.S.A., Inc. To contact NHTSA, you may ei-
ther call the Auto Safety Hotline
tollfree at 18004249393 (or
3660123 in Washington, D.C.
area) or write to: NHTSA, U.S.
Department of Transportation,
Washington, D.C. 20590. You can
also obtain other information about
motor vehicle safety from the Hot-
line.This information has been prepared in ac-
cordance with regulations issued by the
National Highway Traffic Safety Adminis-
tration of the U.S. Department of Trans-
portation. It provides the purchasers and/
or prospective purchasers of Toyota
vehicles with information on uniform tire
quality grading.
Your Toyota dealer will help answer any
questions you may have as you read this
information.
DOT quality grades—All passenger car
tires must conform to Federal Safety
Requirements in addition to these
grades. Quality grades can be found
where applicable on the tire sidewall
between tread shoulder and maximum
section width. For example: Treadwear

Uniform tire quality grading

’03 HIGHLANDER_U (L/O 0208)
2952003 HIGHLANDER from Aug. ’02 Prod. (OM48441U)
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 a half (11/2) times
as well on the government course as a
tire graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics and climate. Traction AA, A, B, C—
The traction
grades, from highest to lowest, are AA, A,
B, and C, and they represent the tire’s
ability to stop on wet pavement as mea-
sured under controlled conditions on spe-
cified government 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 (straight
ahead) 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 dissi-
pate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to de-
generate and reduce tire life, and exces-
sive temperature can lead to sudden tire
failure. The grade C corresponds to a lev-
el 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 perfor-
mance on the laboratory test wheel than
the minimum required by law. Warning: The temperature grades for this
tire are established for a tire that is prop-
erly inflated and not overloaded. Exces-
sive speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and possible
tire failure.
