* If the tire pressure monitoring system has a malfunction, the tire pressure warning
light fl ashes for about 1 minute when the ignition is switched ON and then continues
illuminating. Have your vehicle checked by an Authorized Mazda Dealer as soon as
possible.
WARNING
If the tire pressure monitoring system warning light illuminates or fl ashes, or the tire
pressure warning beep sound is heard, decrease vehicle speed immediately and avoid
sudden maneuvering and braking:
If the tire pressure monitoring system warning light illuminates or fl ashes, or the tire
pressure warning beep sound is heard, it is dangerous to drive the vehicle at high
speeds, or perform sudden maneuvering or braking. Vehicle drivability could worsen
and result in an accident.
To determine if you have a slow leak or a fl at, pull over to a safe position where you can
check the visual condition of the tire and determine if you have enough air to proceed
to a place where air may be added and the system monitored again by an Authorized
Mazda Dealer or a tire repair station.

Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated.
Have the problem taken care of as soon as possible before it develops into a more
serious situation that could lead to tire failure and a dangerous accident.

Tire Pressure Monitoring
System Warning Light
* When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), tire pressure is too low in one or
more tires.
WARNING
If the tire pressure monitoring system
warning light illuminates or fl ashes,
or the tire pressure warning beep
sound is heard, decrease vehicle
speed immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system
warning light illuminates or fl ashes, or
the tire pressure warning beep sound
is heard, it is dangerous to drive the
vehicle at high speeds, or perform
sudden maneuvering or braking.
Vehicle drivability could worsen and
result in an accident.
To determine if you have a slow leak
or a fl at, pull over to a safe position
where you can check the visual
condition of the tire and determine
if you have enough air to proceed to
a place where air may be added and
the system monitored again by an
Authorized Mazda Dealer or a tire
repair station.

Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken
care of as soon as possible before it
develops into a more serious situation
that could lead to tire failure and a
dangerous accident. Inspect the tires and adjust to the
specifi ed infl ation pressure (page
6-43 ).
NOTE
 Perform tire pressure adjustment when
the tires are cold. Tire pressure will
vary according to the tire temperature,
therefore let the vehicle stand for 1
hour or only drive it 1.6 km (1 mile) or
less before adjusting the tire pressures.
When pressure is adjusted on hot tires
to the cold infl ation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops below
specifi cation.
Also, an illuminated TPMS warning
light, resulting from the tire air
pressure dropping due to cold ambient
temperature will remain illuminated
even if the ambient temperature rises.
In this case, it will also be necessary
to adjust the tire air pressures. If the
TPMS warning light illuminates due to
a drop in tire air pressure, make sure to
check and adjust the tire air pressures.

 Tires lose air naturally over time and
the TPMS cannot tell if the tires are
getting too soft over time or you have
a fl at. However, when you fi nd one low
tire in a set of four-that is an indication
of trouble; you should have someone
drive the vehicle slowly forward so
you can inspect any low tire for cuts
and any metal objects sticking through
tread or sidewall. Put a few drops of
water in the valve stem to see if it
bubbles indicating a bad valve. Leaks
need to be addressed by more than
simply reinfl ating the tire as leaks are
dangerous — take it to an Authorized
Mazda Dealer.

Tire Information (U.S.A.)
Tire Labeling
Federal law requires tire manufacturers to place standardized information on the sidewall of
all tires. This information identifi es and describes the fundamental characteristics of the tire
and also provides a tire identifi cation number for safety standard certifi cation and in case of
a recall.
Information on Passenger Vehicle Tires
Please refer to the sample below.


1. TIN: U.S. DOT tire identifi cation number
2. Passenger car tire

Customer Information and Reporting Safety Defects
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 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 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 Infl 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 specifi 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 specifi 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 specifi 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.

Location of the Tire Label (Placard)
You will fi nd the tire label containing tire infl ation pressure by tire size and other important
information on the driver's side B-pillar or on the edge of the driver's door frame.

SAMPLE


Recommended Tire Infl ation Pressure
On the tire label you will fi nd the recommended tire infl ation pressure in both kPa and
psi for the tires installed as original equipment on the vehicle. It is very important that the
infl ation pressure of the tires on your vehicle is maintained at the recommended pressure.
You should check the tire pressure regularly to insure that the proper infl ation pressure is
maintained.
Refer to Tires on page 9-9 .
NOTE
Tire pressures listed on the vehicle placard or tire information label indicate the
recommended cold tire infl ation pressure, measured when the tires are cold, after the vehicle
has been parked for at least 3 hours. As you drive, the temperature in the tire warms up,
increasing the tire pressure.
