Replacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.

Replace all four tires at the same time:
Replacing just one tire is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tires at the
same time.

If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.

New treadTread wear indicator
Worn tread

You should replace the tire before the band
crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-126 .
N O T E
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 8-24 .

Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it is properly
inÀ ated and stored.
N O T E
The temporary spare tire condition
gradually deteriorates even if it has not
been used.

The temporary spare tire is easier to
handle because of its construction which
is lighter and smaller than a conventional
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 9-10 .

CAUTION
 


¾ Do not use your temporary spare tire
rim with a snow tire or a conventional
tire. Neither will properly fi t and could
damage both tire and rim.
 


¾ 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.
 


¾ 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 6-46 ).

Replacing a Wheel
WARNING
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be aff ected, leading to loss of
control and an accident.

CAUTION
A wrong-sized wheel may adversely
aff ect:




¾ Tire fi t



¾ Wheel and bearing life



¾ Ground clearance



¾ Snow-chain clearance



¾ Speedometer calibration



¾ Headlight aim



¾ Bumper height



¾ Tire Pressure Monitoring System *
N O T E




y 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).
 


y 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 À at spots.

WARNING
Do not replace the xenon fusion bulbs
yourself:
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. Consult an Authorized
Mazda Dealer when the replacement is
necessary.

Never touch the glass portion of a
halogen bulb with your bare hands
and always wear eye protection when
handling or working around the 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 fl ying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.

Always keep halogen bulbs out of the
reach of children:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.

CAUTION
When removing the lens or lamp unit
using a fl athead screwdriver, make
sure that the fl athead screwdriver does
not contact the interior terminal. If
the fl athead screwdriver contacts the
terminal, a short circuit may occur.

N O T E
 


y To replace the bulb, contact an
Authorized Mazda Dealer.
 


y If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
 


y Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.

WARNING
Do not replace the main fuse and
multiplex slow blow fuse by yourself.
Have an Authorized Mazda Dealer
perform the replacement:
Replacing these fuses by yourself is
dangerous because they are high
current fuses. Incorrect replacement
could cause an electrical shock or a
short circuit resulting in a fi re.

4. Reinstall the cover and make sure that
it is securely installed.

Maintenance and Care
Appearance Care
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 damage the
protective coating; also, cleaners and
detergents may discolor or deteriorate
the paint.

Pay special attention to removing salt, dirt,
mud, and other foreign material from the
underside of the fenders, and make sure
the drain holes in the lower edges of the
doors and rocker panels are clean.

Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits
can damage the ¿ nish if not removed
immediately. When prompt washing with
plain water is ineffective, use a mild soap
made for use on vehicles.

Thoroughly rinse off all soap with
lukewarm or cold water. Do not allow
soap to dry on the ¿ nish.

After washing the vehicle, dry it with a
clean chamois to prevent water spots from
forming.
WARNING
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 aff ected.

When using an automatic car wash






y Retract the door mirrors.



y The automatic car wash brushes could
reduce the paint lustre or hasten paint
deterioration.

When using a high water pressure car
wash
High water temperature and high water
pressure car washers are available
depending on the type of car wash
machine. If the car washer nozzle is
put too close to the vehicle, the force of
the spray could damage or deform the
molding, affect the sealability of parts,
and allow water to penetrate the interior.
Keep a suf¿ cient space (30 cm (12 in) or
more) between the nozzle and the vehicle.
In addition, do not spend too much time
spraying the same area of the vehicle, and
be very careful when spraying between
gaps in doors and around windows.

Appearance Care
*Some models.
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
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 aff ected.

Aluminum Wheel Maintenance *
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels.

N O T E
 


y Do not use a wire brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
 


y Always use a sponge or soft cloth to
clean the wheels.
  Rinse the wheels thoroughly with
lukewarm or cold water. Also, be sure
to clean the wheels after driving on
dusty or salted roads to help prevent
corrosion.
 


y Avoid washing your vehicle in an
automatic car wash that uses high-
speed or hard brushes.

Plastic Part Maintenance
 












y When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
recti¿ ed spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a signi¿ cant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, À ush with water
immediately.
 


y If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or À uids such as
gasoline, oil, engine coolant, or battery
À uid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or À uids using a
soft cloth immediately.
