N O T E
 


y Always check tire pressure when tires
are cold.
 


y Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
 


y UnderinÀ ation 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.
 


y OverinÀ ation 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 inÀ ating,
have it inspected.

Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help increase tire life
and distribute wear more evenly.
Refer to Scheduled Maintenance on
page 6-4 .


During rotation, inspect them for correct
balance.


Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward

Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

 


y Incorrect tire pressure



y Improper wheel alignment



y Out-of-balance wheel



y Severe braking

After rotation, inÀ ate all tire pressures to
speci¿ cation (page 9-8 ) and inspect the
lug nuts for tightness.
(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 4-129 .
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 reduced if rotated from side to
side.

Maintenance and Care
Owner Maintenance
*Some models.
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 6-44 ).

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 .

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.

Maintenance and Care
Appearance Care
*Some models.
Underbody 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, À oor pan, and exhaust
system, even though these parts may be
coated with anti-corrosive material.

Thoroughly À ush 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
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.
 


y (18-inch wheel vehicle) 
 If your aluminum wheels lose luster,
apply wax which contains no polishing
powder.

y Make sure the screw thread is
adequately lubricated.

Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the front wheels (driving wheels):
Driving with the temporary spare tire
on one of the front driving wheels is
dangerous. Handling will be aff ected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the front wheel and install the
temporary spare tire to the rear.

N O T E
If the following occurs while driving, it
could indicate a À at tire.




y Steering becomes dif¿ cult.



y The vehicle begins to vibrate
excessively.
 


y The vehicle pulls in one direction.
If you have a À at tire, drive slowly to a
level spot that is well off the road and out
of the way of traf¿ c to change the tire.
Stopping in traf¿ c or on the shoulder of a
busy road is dangerous.
WARNING
Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure someone.
No person should place any portion
of their body under a vehicle that is
supported by a jack.

Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in
a vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.

N O T E
Make sure the jack is well lubricated

Locking Lug Nuts *
If your vehicle has Mazda optional
antitheft wheel lug nuts, one on each
wheel will lock the tires and you must
use a special key to unlock them. This
key will attach to the lug wrench.
Register them with the lock manufacturer
by ¿ lling out the card provided in the
glove compartment and mailing it in the
accompanying envelope. If you lose this
key, consult an Authorized Mazda Dealer
or use the lock manufacturer's order form,
which is with the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire
is installed, one of the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.

Special key Antitheft lug nut

To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the
antitheft lug nut, and be sure to hold

WARNING
Make sure the mounting surfaces of
the wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire,
not removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off , resulting in
an accident.

2. Mount the spare tire.
3. Install the lug nuts with the beveled
edge inward; tighten them by hand.



WARNING
Do not apply oil or grease to lug nuts
and bolts and do not tighten the
lug nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off , resulting in an accident.
In addition, lug nuts and bolts could
be damaged if tightened more than
necessary.

4. Turn the lug wrench counterclockwise
and lower the vehicle. 5. Use the lug wrench to tighten the nuts

WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off . This could result
in loss of vehicle control and cause a
serious accident.

Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same confi guration:
Because the wheel studs and lug nuts
