WARNING
Metric Studs and Lug Nuts:
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. Be sure to
reinstall the same nuts you removed or
replace them with metric nuts of the
same configuration.
Incorrect Tire Air Pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
Don't drive with any tires that have
incorrect air pressure. When you
check the regular tires' air pressure,
check the spare tire, too.
5. Store the damaged tire in the trunk. Have the damaged tire repaired as soon
as possible.
NOTE
To prevent the jack and tool from
rattling, store them properly.

The battery is in the trunk.
qBattery Maintenance
To get the best service from a battery:
lKeep it securely mounted.
lKeep the top clean and dry.
lKeep terminals and connections clean,
tight, and coated with petroleum jelly
or terminal grease.
lRinse off spilled electrolyte
immediately with a solution of water
and baking soda.
lIf the vehicle will not be used for an
extended time, disconnect the battery
cables.
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-6)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.

qTire Inflation Pressure
WARNING
Incorrect Tire Inflation:
Overinflation or underinflation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in
a serious accident. Always inflate the
tires to the correct pressure (page
10-6).
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures
for the best ride, top handling, and
minimum tire wear.
Refer to the specification charts (page
10-6).
NOTE
lAlways check tire pressure when
tires are cold.
lWarm tires normally exceed
recommended pressures. Don't
release air from warm tires to adjust
the pressure.
lUnderinflation can cause reduced
fuel economy and poor sealing of the
tire bead, which will deform the
wheel and cause separation of tire
from rim.
lOverinflation can produce a harsh
ride and a greater possibility of
damage from road hazards.
Keep your tire pressure at the correct
levels. If one frequently needs
inflating, have it inspected.
q Tire Rotation
To equalize tread wear, rotate the tires
every 12,000 km (7,500 miles)/8,000 km*
(5,000 miles) or sooner if irregular wear
develops. During rotation, inspect them
for correct balance.
* Unique driving conditions for U.S.A.,
Canada and Puerto Rico

Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
lIncorrect tire pressure
lImproper wheel alignment
lOut-of-balance wheel
lSevere braking
After rotation, inflate all tire pressures to
specification (page 10-6) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tire performance
will be weakened if rotated from side to
side.
CAUTION
Limited-Slip Differential system;
don't use the following:
lTires not of the designated size
lTires of different sizes or types at the
same time
lTires not sufficiently inflated
If these instructions aren't followed, the
rotation of the left and right wheels will
be different and will thus apply a
constant load on the limited-slip
differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Worn Tires:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Always use tires that are in good
condition.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace it before the band is
across the entire tread.
qTemporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
and stored.
The temporary spare tire is easier to
handle because of its construction. It is
lighter and smaller than a conventional
tire and should be used only for an
emergency and only for a short distance.

Use the temporary only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2 kgf/
cm
2or bar, 60 psi).
CAUTION
lDon't use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage both
tire and rim.
lThe temporary spare tire has a tread
life of up to 5,000 km (3,000 miles),
depending on road conditions and
driving habits.
lThe temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type of
temporary spare (page 8-32).
qReplacing a Wheel
WARNING
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.
CAUTION
A wrong-sized wheel may adversely
affect:
lTire fit
lWheel and bearing life
lGround clearance
lSnow-chain clearance
lSpeedometer calibration
lHeadlight aim
lBumper height
lLimited-Slip Differential System
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

qWater Marks
Occurrence
Rain, fog, dew, and even tap water can
contain harmful minerals such as salt and
lime. If moisture containing these
minerals settles on the vehicle and
evaporates, the minerals will concentrate
and harden to form white rings. The rings
can damage your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These
steps should be taken immediately after
you find water marks on your vehicle's
finish.
qPaint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel.
NOTE
lThe paint chipping zone varies with
the speed of the vehicle. For
example, when traveling at 90 km/h
(56 mph), the paint chipping zone is
50 m (164 ft).
lIn low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
lChipped paint can lead to rust
forming on your Mazda. Before this
happens, repair the damage by using
Mazda touch-up paint according to
the instructions in this section.
Failure to repair the affected area
could lead to serious rusting and
expensive repairs.

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.
qTread Wear
The tread wear grade is a comparative rating based on the wear rate of the 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 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 significantly from the norm because of variations in driving habits, service
practices and differences in road characteristics and climate.
qTraction-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.
qTemperature-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 specified 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.

WARNING
The temperature grade for this tire is established for a tire that is properly inflated and
not overloaded. Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire failure.
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.
q Uniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example:
