Maintenance and Care
Owner Maintenance
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinfl 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.
Overinfl 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 infl 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:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, infl ate all tire pressures to
specifi cation (page 9-9 ) 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 4-153 .
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.

*Some models.
CAUTION
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.
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 6-45 ).
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 8-24 .
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:
Tire fi t
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 fl at spots.

Maintenance
Always keep the jack clean.
Make sure the moving parts are kept
free from dirt or rust.
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.
CAUTION
When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
To avoid damage to the temporary
spare tire or to the vehicle, observe the
following precautions:
Do not exceed 80 km/h (50 mph).
Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the
ground clearance is reduced.
Do not use a tire chain on this tire
because it will not fi t properly.
Do not use your temporary spare
tire on any other vehicle, it has been
designed only for your Mazda.
Use only one temporary spare tire on
your vehicle at the same time.

Locking Lug Nuts
If your vehicle has Mazda optional
antitheft wheel lug nuts, each wheel will
have one locking lug nut that locks the
wheel and tire, and you must use a special
key to unlock the locking lug nut. This
key is stored in the glove compartment.
Register the key and lug nuts with the
lock manufacturer by fi 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

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
Tire Infl ation Pressure
Inspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specifi ed on the vehicle tire information placard or tire label for optimum service.
Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (5,000 miles) to
help increase tire life and distribute wear more evenly.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, infl ate all tire pressures to specifi cation (page 9-9 ) 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 4-153 .
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.
