▼ Add-On Non-Genuine Parts and
Accessories
Non-genuine parts and accessories for
Mazda vehicles can be found in stores.
These may
fit your vehicle, but they are
not approved by Mazda for use with
Mazda vehicles. When you install
non-genuine parts or accessories, they
could affect your vehicle's
performance or safety systems; the
Mazda warranty doesn't cover this.
Before you install any non-genuine
parts or accessories, consult an
Authorized Mazda Dealer.
WARNING
Always consult an Authorized Mazda
Dealer before you install non-genuine
parts or accessories:
Improperly designed parts or
accessories could seriously affect your

Cell Phones Warning
▼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
(U.S.A. and Canada)
▼ Event Data Recorder
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:
How various systems in your vehicle
were operating;
Whether or not the driver and
passenger safety belts were buckled/
fastened;
How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
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:
A written agreement from the vehicle
owner or the lessee is obtained
Officially requested by the police or
other law enforcement authorities
Used as a defense for Mazda in a
lawsuit, claim, or arbitration
Ordered by a judge or court
However, if necessary Mazda will:
Use the data for research on Mazda
vehicle performance, including
safety.
Disclose the data or the summarized
data to a third party for research
purposes without disclosing vehicle
or owner identification 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
Tra ffi c Safety
Administration for grading tires by
tread wear, traction, and temperature
performance.
▼ Trea d Wea r
The tread wear 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 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 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
specified 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.
▼ Te m p e ra t u r e - 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 specified 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.

WARNING
Keep your vehicle's tires properly
inflated and not overloaded:
Driving with improperly inflated or
overloaded tires is dangerous.
Excessive speed, underinflation, 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
inflated 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 Labeling
▼Tire Labeling
Federal law requires tire manufacturers
to place standardized information on
the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of the
tire and also provides a tire
identification
number for safety
standard certification and in case of a
recall.

P215/65R15 95H is an example of a
tire size and load index rating. Here is
an explanation 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
either 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.
65
“65” is the aspect ratio. This two-digit
number indicates the tire's ratio of
height to width.
R
“R” is the tire construction symbol. R
indicates “Radial ply construction”.
15
“15” is the wheel rim diameter in
inches.

* For tires with a maximum speed capability over
149 mph, tire manufacturers sometimes use the
letters ZR. For tires with a maximum speed
capability over 186 mph, tire manufacturers
always use the letters ZR.
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 Identification 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 Inflation
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
Trea d wea r : The tread wear 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.
Traction: The traction grades, from
highest to lowest are AA, A, B, and C.
