Mounting the Tire
1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.

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 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. 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 configuration:
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.
5. Remove the tire blocks and store the
tools and jack.
6. Check the inflation pressure. Refer to
Tires on page 9-8.
NOTE
(With tire pressure monitoring system)
Do not press the tire pressure monitoring
system set switch after installing the spare
tire. The switch is only to be pressed after
installing the repaired flat tire or installing
a replacement tire (page 4-16).

Warning/Indicator Lights and Warning Sounds
*Some models.
SignalWarningAction to be taken
Door-Ajar Warning Light
The light turns on if any door is not closed securely.Close the door securely.
Low Washer Fluid Level Warning Light*
This warning light indicates that little washer fluid remains.Add washer fluid (page 6-31).
(Illuminate)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 6-41).
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)
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 requ\
ired 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.
For example:
