tire. This tire should be used only for an
emergency and only for a short distance.

Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-7.

CAUTION
Do not 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.
 The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 The 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 6-38).
NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page 8-25.
▼ Replacing a Wheel
WA R N I N G
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be
affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
*
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

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.

CAUTION
If your Mazda is damaged and needs metal
parts repaired or replaced, make sure the
body shop applies anti-corrosion materials
to all parts, both repaired and new. This
will prevent them from rusting.
▼Bright-Metal Maintenance
Use tar remover to re
move road tar and
insects. Never do this with a knife or
similar tool.
To prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high luster.
During 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
Do not 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.
▼ Underbody Maintenance
Road chemicals and salt used for ice and
snow removal and solv
ents used for dust
control may collect on the underbody. If
not removed, they wi ll 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.
WA R N I N G
Dry off brakes that have become wet by
driving slowly, releasing the accelerator
pedal and lightly applying the brakes
several times until the brake performance
returns to normal:
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.
▼ Aluminum Wheel Maintenance*
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.

4. Remove moisture with a dry, soft cloth and allow the leather to further dry in a
well-ventilated, shaded area. If the
leather gets wet such as from rain,
remove the moisture and dry it as soon
as possible.
NOTE
Because genuine leather is a natural
material, its surface is not uniform and
it may have natural scars, scratches,
and wrinkles.
To maintain the quality for as long as
possible, periodical maintenance, about
twice a year, is recommended.
If the leather upholstery comes into
contact with any of the following, clean
it immediately.
Leaving it uncleaned could cause
premature wear, mold, or stains.
Sand or dirt
Grease or oil, such as hand cream
Alcohol, such as in cosmetic or hair
dressing items
If the leather upholstery gets wet,
promptly remove moisture with a dry
cloth. Remaining moisture on the
surface may cause deterioration such as
hardening and shrinkage.
Exposure to direct sunlight for long
periods may cause deterioration and
shrinkage. When parking the car under
direct sunlight for long periods, shade
the interior using sunshades.
Do not leave vinyl products on the
leather upholstery for long periods.
They may affect the leather quality and
coloring. If the cabin temperature
becomes hot, the vinyl may deteriorate
and adhere to the genuine leather.
▼Plastic Part Maintenance
CAUTION
Do not use polishing agents.
Depending on the product ingredients,
they could cause discoloration, stains,
cracks or peeling of the coating.
▼Instrument Panel Top Maintenance
1. Wipe the soiled area with a soft cloth
soaked in a mild detergent (approx.

▼Active Driving Display
Maintenance*
The combiner and mirror surface have a
special coating. When cleaning it, do not
use a hard cloth, a cloth with a rough
surface, or cleaning detergent. Use a
fine-textured, soft cloth.
If a chemical solvent
gets on the combiner
or mirror surface, wipe it off immediately.
Otherwise, they could be damaged and the
surface coating could be scratched.
▼ Panel Maintenance
If a panel becomes soiled, wipe it off with
a soft cloth soaked in clean water and
thoroughly wrung out.
If some areas require further cleaning, use
the following procedure:
1. Wipe the soiled ar
ea with a soft cloth
soaked in a mild detergent (approx.
5 %) diluted with water.
2. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
NOTE
Be particularly careful when cleaning
shiny surface panels and metallic parts
such as plating as they can be scratched
easily.
▼Cleaning the Window Interiors
If the windows become covered with an
oily, greasy, or waxy film, clean them with
glass cleaner. Follow the directions on the
container.
CAUTION

Do not scrape or scratch the inside of the
window glass. It could damage the
thermal filaments.
 When washing the inside of the window
glass, use a soft cloth dampened in
lukewarm water, gently wiping the
thermal
filaments.
Use of glass cleaning products could
damage the thermal filaments.
▼ Cleaning the Floor Mats
Rubber floor mats should be cleaned with
mild soap and water only.
WA R N I N G
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning rubber
floor
mats:
Cleaning the rubber floor mats with rubber
cleaning products makes the floor mats
slippery.
This may cause an accident when
depressing the accelerator, brake, or clutch
(Manual transaxle) pedal or when getting
in or out of the vehicle.
After removing the floor mats for
cleaning, always reinstall them securely
(page 3-41).
