9. Remove the lug nuts by turning them
counterclockwise; then remove the
wheel and center cap.
Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lug nuts, one on each
wheel will lock the tires and you must
use a special key to unlock them. This
key will attach to the lug wrench.
Register them with the lock manufacturer
by filling out the card provided in the
glove compartment and mailing it in the
accompanying envelope. If you lose this
key, consult an Authorized Mazda Dealer
or use the lock manufacturer's order form,
which is with the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire
is installed, one of the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.

Warning Light*
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.

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 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
6-43).
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 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.

The light turns on if the windshield and
the radar sensor are dirty or there is a
malfunction in the system. Verify the reason why the warning light
is illuminated on the center display (page
7-24).
If the reason why the warning light is
illuminated is due to a dirty windshield, clean
the windshield.
If the warning light is illuminated because of
a dirty radar sensor, clean the front emblem.
For any other reasons, have the vehicle
inspected at an Authorized Mazda Dealer.

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
Traffic 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 specified 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 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.
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 specified 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 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 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 between tread shoulder
and maximum section width.
