Uniform tire quality grading
If you believe that your vehicle has
a defect whi ch coul d cause a cr ash
or could cause injury or death, you
should immediately inform the Na-
tional Highway Traffic Safety Ad-
ministration (NHTSA) in addition to
notifying Toyota Motor Sales,
U.S.A., Inc.
(Toll±free: 1±800±331±4331).
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety de-
fect exists in a group of vehicles, it
may order a recall and remedy
campaign. However, NHTSA cannot
become involved in individual prob-
lems between you, your dealer, or
Toyota Motor Sales, U.S.A., Inc.To contact NHTSA, you may either
call the Auto Safety Hotline toll±free
at 1±800±424±9393 (or 366±0123 in
Washington,D.C. area) or write to:
NHTSA. U.S.Department of Trans-
portation. Washington,D.C. 20590.
You can also obtain other information

Uniform tire quality grading
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 gradesÐAll passenger ve-
hicle tires must conform to Federal
Safety Requirements in addition to
these grades. These quality grades are
molded on the sidewall.
TreadwearÐThe 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 (1±1/2) 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, CÐThe 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, CÐThe 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.

ACCESSORIES
SRS AIRBAG
1. General
The electrically sensing type SRS (Supplemental Restraint System) airbag is designed to help lessen the
shock to the driver and front passenger as a supplement to the seat belt.
A 3-sensor type airbag system detects the deceleration during collision by the front airbag sensors and the
airbag sensor that is enclosed in the airbag sensor assembly.

System Diagram 
The activation processes of the
SRS airbag is as illustrated below.

4. Construction and Operation
Front Airbag Sensor
The front airbag sensor consists of rotor, movable contact point and a stationary contact point.
The rotor is fixed by the initial set load of the movable contact point. At the same time, the movable contact
point restrains the movement of the rotor which is generated during vehicle deceleration, thus preventing
the unintended activation of the system.
If a sudden deceleration that exceeds a predetermined value occurs due to a collision of the vehicle, the rotor
will rotate. The rotational movement of the rotor pushes the movable contact point and causes the movable
and stationary contact points to come into contact. As a result, an ON signal is generated and transmitted
to the airbag sensor assembly.
5. System Operation
Ignition Judgement and Condition
When the vehicle collides in the hatched area (Fig. 1) and the shock is larger than a predetermined level,
the airbag and the seat belt pretensioner are activated automatically. The airbag sensor is characteristically
turned in such a way that can judge the need for ignition in collisions within the hatched area.
The safing sensor is designed to be activated by a smaller deceleration rate than that of the airbag sensor.
As illustrated in Fig. 2 below, ignition is operated when current flows to the squib. This happens when a
safing sensor and the airbag sensor go on simultaneously.
Airbag sensor assembly judges whether or not to inflate the airbag in accordance with ON / OFF of the front
airbag sensor and the deceleration detected by the airbag sensor.
