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 safety
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/fastened;



y How far (if at all) the driver was depressing the accelerator and/or brake 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 near 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 personally identifying
data routinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access 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 if they have access
to the vehicle or the EDR.

Mazda will not disclose any of the data recorded in an EDR to a third party unless:
 


y A written agreement from the vehicle owner or the lessee is obtained



y Of¿ 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 purposes without
disclosing vehicle or owner identi¿ 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
Traf¿ c Safety Administration for grading tires by tread wear, traction, and temperature
performance.
Tr e a d We a r
The tread wear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a speci¿ ed government test course.
For example, a tire graded 150 would wear one-and-a-half 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 signi¿ 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 conditions on speci¿ 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 controlled conditions on
a speci¿ ed indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.

Grade C corresponds to a level of performance which all passenger vehicle 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.

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 over 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 between tread shoulder
and maximum section width.

Tire Information (U.S.A.)
M S or M/S: Mud and Snow
AT: All Terrain.
AS: All Season. The “M
S” or “M/S” indicates that the tire has some functional use in mud
and snow.
U.S. DOT Tire Identi¿ 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 example, 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.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by the
tire.
Maximum Permissible InÀ ation Pressure
This number is the greatest amount of air pressure that should ever be put in the tire under
normal driving conditions.
Tread Wear, Traction and Temperature Grades
Tread wear: The tread wear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a speci¿ ed 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.
Traction: The traction grades, from highest to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measured under controlled conditions
on speci¿ ed government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Temperature: 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 speci¿ ed indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local governments may require true snow tires, those with very
deeply cut tread. These tires should only be used in pairs or placed on all four wheels. Make
sure you purchase snow tires that are the same size and construction type as the other tires
on your vehicle.
