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 ¿ lling 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.

Special key Antitheft lug nut

To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the
antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
3. Place the lug wrench on top of the key
and apply pressure. Turn the wrench
counterclockwise.

WARNING
Make sure the mounting surfaces of
the wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire,
not removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off , resulting in
an accident.

2. Mount the spare tire.
3. Install the lug nuts with the beveled
edge inward; tighten them by hand.



WARNING
Do not apply oil or grease to lug nuts
and bolts and do not tighten the
lug nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off , resulting in an accident.
In addition, lug nuts and bolts could
be damaged if tightened more than
necessary.

4. Turn the lug wrench counterclockwise
and lower the vehicle. 5. Use the lug wrench to tighten the nuts
in the order shown.



If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.

Nut tightening torque
N·m (kgf·m, ft·lbf) 108—147 (12—14, 80—108)

WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off . This could result
in loss of vehicle control and cause a
serious accident.

Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same confi guration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.

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
speci¿ ed inÀ ation pressure (page 6-42 ).
N O T E
y 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 inÀ ation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops below
speci¿ 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.
y Tires lose air naturally over time and
the TPMS cannot tell if the tires are
getting too soft over time or you have
a À at. However, when you ¿ 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 reinÀ ating the tire
as leaks are dangerous — take it to 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
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.
For example:
