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
lA wrong-sized wheel may adversely
affect:
lTire fitlWheel and bearing lifelGround clearancelSnow-chain clearancelSpeedometer calibrationlHeadlight aimlBumper heightlTire Pressure Monitoring SystemlLimited-Slip Differential System
l(With Tire Pressure Monitoring
System)
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 5-29.
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.

4. After drying it completely, apply a
suitable top coat material to the area.
Of course there will be no problem if you
assign the work to an Authorized Mazda
Dealer.
qCavity Protection
Cavities are treated for protection at the
factory, but additional protective treatment
after the vehicle has been put into use will
extend the life of the body.
We recommend that you consult an
Authorized Mazda Dealer concerning this
additional precaution.
qBright-Metal Maintenance
lUse tar remover to remove road tar and
insects. Never do this with a knife or
similar tool.
lTo prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high luster.
lDuring cold weather or in coastal areas,
cover bright-metal parts with a coating
of wax or preservative heavier than
usual. It would also help to coat them
with noncorrosive petroleum jelly or
some other protective compound.
CAUTION
Don't use steel wool, abrasive cleaners,
or strong detergents containing highly
alkaline or caustic agents on chrome-
plated or anodized aluminum parts.
This may result in damage to the
protective coating and cause
discoloration or paint deterioration.
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.

qUndercoating
This special coating is applied to the
critical parts of the underside to protect
vehicles from damage caused by
chemicals or stones. This coating is liable
to be damaged with time. Check this
coating periodically.
An Authorized Mazda Dealer are well
informed on how repairs should be made.
Consult an Authorized Mazda Dealer.
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.
Interior Care
qDashboard Precautions
Prevent caustic solutions such as perfume
and cosmetic oils from contacting the
dashboard. They'll damage and discolor it.
If these solutions get on the dashboard,
wipe them off immediately.
CAUTION
Do not use glazing agents.
Glazing agents contain ingredients
which may cause discoloration,
wrinkling, cracks and peeling.
qCleaning the Upholstery and
Interior Trim
Vinyl
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl with a leather-and-vinyl
cleaner.
Leatherí
Real leather isn't uniform and may have
scars, scratches, and wrinkles. Clean it
with a leather cleaner or mild soap.
Wipe it with adampsoft cloth; then dry
and buff it with adrysoft cloth.
Fabric
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner.
Clean it with a mild soap solution good
for upholstery and carpets. Remove fresh
spots immediately with a fabric spot
cleaner.

Piano black panelí
The following parts are fitted with panels
that have been treated with a special
coating that resists scratching.
Steering wheel (partial)
When the panel needs to be cleaned, use a
soft cloth to wipe off dirt from the surface.
NOTE
Scratches or nicks on the panels
resulting from the use of a hard brush or
cloth may not be repairable.
qCleaning the Lap/Shoulder Belt
Webbing
Clean the webbing with a mild soap
solution recommended for upholstery or
carpets. Follow instructions. Don't bleach
or dye the webbing; this may weaken it.
After cleaning the belts, thoroughly dry
the belt webbing and make sure there is
no remaining moisture before retracting
them.
WARNING
Damaged Seat Belt:
Using damaged seat belts is
dangerous. In a collision, damaged
belts cannot provide adequate
protection. Have an Authorized Mazda
Dealer replace damaged belts
immediately.

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)
TO SEAT BEADS-ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT
TIRES.
lTIRE FAILURE DUE TO UNDER-INFLATION/OVERLOADING/DAMAGE-
