If the tire pressure monitoring system has a malfunction, the tire press\
ure warning
light flashes 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 flashes, 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 flashes, 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 flat, 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.

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 flashes,
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 flashes, 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 flat, 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 specified
inflation pressure (page
6-41).
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 inflation
pressure, the TPMS warning light/beep may
turn on after the tires cool and pressure
drops below specification.
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 flat. However,
when you find 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 reinflating
the tire as leaks are dangerous — take it to
an Authorized Mazda Dealer.

Uniform Tire Quality Grading System (UTQGS)
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 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:

Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever be p\
ut 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 t\
he 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. The grades
represent the tire's ability to stop on wet pavement as measured under c\
ontrolled conditions
on specified 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 specified 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. M\
ake
sure you purchase snow tires that are the same size and construction typ\
e as the other tires
on your vehicle.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
 EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH

Tire Information (U.S.A.)
Location of the Tire Label (Placard)
You will find the tire label containing tire inflation 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 Inflation Pressure
On the tire label you will find the recommended tire inflation pressure in both kPa and
psi for the tires installed as original equipment on the vehicle. It is \
very important that the
inflation 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 inflation pressure is
maintained.
Refer to Tires on page 9-8.
NOTE
Tire pressures listed on the vehicle placard or tire information label indicate the
recommended cold tire inflation 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.

Tire Information (U.S.A.)
WARNING
Always check the tire inflation pressures on a regular basis according to the
recommended tire inflation pressure on the tire label and in conjunction with the
information in this owner's manual:Driving your vehicle with under-inflated tires is dangerous.
Under-inflation is the most common cause of failures in any kind of tire and may result
in severe cracking, tread separation or “blowout”, with unexpected loss of vehicle
control and increased risk of injury. Under-inflation increases sidewall flexing and
rolling resistance, resulting in heat buildup and internal damage to the tire. It results in
unnecessary tire stress, irregular wear, loss of control and accidents. A tire can lose up to
half of its air pressure and not appear to be flat!
It is impossible to determine whether or not tires are properly inflated just by looking at
them.
Checking Tire Pressure
1. When you check the air pressure, make sure the tires are cold —meaning they are not hot
from driving even a mile.
2. Remove the cap from the valve on one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by pushing on the metal stem in the center of the valve.
Then recheck the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher inflation pressure.
8. Visually inspect the tires to make sure there are no nails or other objec\
ts embedded that
could poke a hole in the tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, crac\
ks or other
irregularities.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnor\
mally. Here are
some important maintenance points:
Tire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires\
are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire \
wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or soon\
er
if irregular wear develops. Mazda recommends to rotate every 8,000 km (\
5,000 miles) to
help increase tire life and distribute wear more evenly.
Do not include (TEMPORARY USE ONLY) spare tire in rotation.
Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
 Incorrect tire pressure Improper wheel alignment Out-of-balance wheel Severe braking
After rotation, inflate all tire pressures to specification (page 9-8) and inspect the lug
nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure m\
onitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-96.
