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, uneven and
accelerated tire wear, 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, uneven and accelerated tire
wear, 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.
qTire Rotation
To equalize tread wear, rotate the tires if
irregular wear develops. According to the
scheduled maintenance charts.Refer to
Scheduled Maintenance on page 8-3.
During rotation, inspect them for correct
balance.
NOTE
Because your vehicle is not equipped
with a spare tire, you cannot do a tire
rotation safely with the jack that comes
with your vehicle. Have an Authorized
Mazda Dealer perform tire rotation.
Forward
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.
qReplacing 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.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.
NOTE
(With Tire Pressure Monitoring
System)
lWhen tires with steel wire
reinforcement in the sidewalls are
used, the system may not function
correctly even with a genuine wheel.
Refer to System Error Activation on
page 5-29.
lBe sure to install the tire pressure
sensors whenever tires or wheels are
replaced.
Refer to Tires and Wheels on page
5-30.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

lWhen replacing/repairing the tires
or wheels or both, have the work
done by an Authorized Mazda
Dealer, or the tire pressure sensors
may be damaged.
lThe wheels equipped on your
Mazda are specially designed for
installation of the tire pressure
sensors. Do not use non-genuine
wheels, otherwise it may not be
possible to install the tire pressure
sensors.
NOTE
Be sure to install the tire pressure
sensors whenever tires or wheels are
replaced. Refer to Tires and Wheels on
page 5-30.
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.

WARNING
Xenon Fusion Bulb Replacement:
Replacing the xenon fusion bulbs
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Do not replace the xenon
fusion bulbs yourself. Consult an
Authorized Mazda Dealer when the
replacement is necessary.
Handling Halogen Bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it
will explode and serious injuries could
be caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.
qReplacing a Headlight Bulb
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood and find the high and low
beam bulbs in the rear of the headlight
unit.
The outboard bulb is the LOW beam,
and the inboard one is the HIGH beam.
Refer to Light Bulbs on page 8-32.
3. If you are changing the right headlight
bulb, start the engine, turn the steering
wheel all the way to the right, and turn
off engine. If you are changing the left
headlight bulb, turn the steering wheel
to the left.
4. Turn the center section of the plastic
retainer counterclockwise and remove
the retainers and partially peel back the
mudguard.

qUnderbody Maintenance
Road chemicals and salt used for ice and
snow removal and solvents used for dust
control may collect on the underbody. If
not removed, they will speed up rusting
and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust
system, even though these parts may be
coated with anti-corrosive material.
Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try also
to do this every month.
Pay special attention to these areas
because they easily hide mud and dirt.It
will do more harm than good to wet
down the road grime without removing
it.
The lower edges of doors, rocker panels,
and frame members have drain holes that
should not be clogged. Water trapped
there will cause rusting.
WARNING
Driving with Wet Brakes:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been affected.
Dry the brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal.
qAluminum Wheel Maintenance
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
NOTE
lDon't use a wire brush or any
abrasive cleaner, polishing
compound, or solvent on aluminum
wheels. They may damage the
coating.
lOnly use a mild soap or neutral
detergent and always use a sponge or
soft cloth to clean the wheels.
Rinse thoroughly with lukewarm or
cold water. Also, be sure to clean the
wheels after driving on dusty or
salted roads. This helps prevent
corrosion.
lAvoid washing your vehicle in an
automatic car wash that uses high-
speed or hard brushes.
lIf your aluminum wheels lose luster,
wax the wheels.

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.

Tread Wear, Traction and Temperature Grades
Tread 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 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 controlled 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.
Make sure you purchase snow tires that are the same size and construction type as the other
tires on your vehicle.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
lEXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-
MATCH TIRE DIAMETER TO RIM DIAMETER; NEVER EXCEED 40 psi (275 kPa)
