Cell Phones Warning
WARNING
Please comply with the legal regulations concerning the use of communication
equipment in vehicles in your country: Use of any electrical devices such as cell phones, computers, portable radios, vehicle
navigation or other devices by the driver while the vehicle is moving is dangerous. Dialing
a number on a cell phone while driving also ties-up the driver's hands. Use of these
devices will cause the driver to be distracted and could lead to a serious accident. If a
passenger is unable to use the device, pull off the right-of-way to a safe area before use.
If use of a cell phone is necessary despite this warning, use a hands-free system to at least
leave the hands free to drive the vehicle. Never use a cell phone or other electrical devices
while the vehicle is moving and, instead, concentrate on the full-time job of driving.

Event Data Recorder
Event Data Recorder (U.S.A. and Canada)
This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like situations, such as an\
air bag deployment
or hitting a road obstacle, data that will assist in understanding how a\
vehicle’s systems
performed. The EDR is designed to record data related to vehicle dynamics and safet\
y
systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is
designed to record such data as:
 y How various systems in your vehicle were operating; y Whether or not the driver and passenger safety belts were buckled/fasten\
ed; y How far (if at all) the driver was depressing the accelerator and/or b\
rake pedal; and, y How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances \
in which crashes
and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if a non-trivial crash or nea\
r crash-like situation
occurs; no data are recorded by the EDR under normal driving conditions \
and no personal
data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such
as law enforcement, could combine the EDR data with the type of personal\
ly identifying
data routinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and acces\
s to the vehicle
or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law
enforcement, that have the special equipment, can read the information i\
f they have access
to the vehicle or the EDR.
Mazda will not disclose any of the data recorded in an EDR to a third pa\
rty unless:
 y  A written agreement from the vehicle owner or the lessee is obtained y Offi cially requested by the police or other law enforcement authorities y Used as a defense for Mazda in a law suit, claim, or arbitration y Ordered by a judge or court
However, if necessary Mazda will:
 y  Use the data for research on Mazda vehicle performance, including safety\
. y Disclose the data or the summarized data to a third party for research p\
urposes without
disclosing vehicle or owner identifi cation information.

Uniform Tire Quality Grading System (UTQGS)
Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S\
. National Highway
Traffi c Safety Administration for grading tires by tread wear, traction, and temperature
performance.
Tread Wear
The tread wear grade is a comparative rating based on the wear rate of t\
he tire when tested
under controlled conditions on a specifi ed government test course.
For example, a tire graded 150 would wear one-and-a-half times as well o\
n 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 signifi cantly from the norm because of 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. These grades represent the
tire's ability to stop on wet pavement as measured under controlled cond\
itions on specifi ed
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 acceleration cornering (turning), hydroplaning, or peak traction
characteristics.
Temperature-A, B, C
The temperature grades A (the highest), B, and C, represent the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under c\
ontrolled conditions on
a specifi ed indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degener\
ate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger vehicl\
e 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 requ\
ired by law.

Uniform Tire Quality Grading System (UTQGS)
WARNING
Keep your vehicle's tires properly infl ated and not overloaded:
Driving with improperly infl ated or overloaded tires is dangerous. Excessive speed,
underinfl ation, or excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure. The temperature grade for this tire is established for a
tire that is properly infl ated and not overloaded.
These grades will be added to the sidewalls of passenger vehicle tires o\
ver the next several
years according to a schedule established by the NHTSA and the tire manufacturers.
The grade of tires available as standard or optional equipment on Mazda \
vehicles may vary
with respect to grade.
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND TO
ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.
UNIFORM TIRE QUALITY GRADING
Quality grades can be found where applicable on the tire sidewall betwee\
n tread shoulder
and maximum section width.
For example:

of the various components of that tire size and load index rating. Note \
that the tire size and
load index rating may be different from the example.
P
Indicates a tire that may be installed on cars, SUVs, minivans and light\
trucks as designated
by the Tire and Rim Association (T&RA).
NOTE
If your tire size does not begin with a letter this may mean it is designated by ei\
ther ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire Manufacturing
Association).
215
“215” is the nominal width of the tire in millimeters. This three-digit number gives the
width in millimeters of the tire from sidewall edge to sidewall edge. In\
general, the larger
the number, the wider the tire.

U.S. DOT Tire Identifi cation Number (TIN)
This begins with the letters “DOT” which indicates the tire meets \
all federal standards. The
next two numbers or letters are the plant code where it was manufactured\
, and the last four
numbers represent the week and year the tire was manufactured. For examp\
le, the numbers
457 means the 45st week of 1997. After 2000 the numbers go to four digits. For example,
the number 2102 means the 21th week of 2002. The other numbers are marketing codes
used at the manufacturer's discretion. This information is used to contact consumers if a tire
defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-coated fabric in the tire.
In general, the greater the number of plies, the more weight a tire can \
support. Tire
manufacturers also must indicate the tire materials, which include steel\
, nylon, polyester,
and other.
