Owner Maintenance
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire infl ation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Diff erent Tire Types:
Driving your vehicle with diff erent
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.

Using Wrong-Sized Tires:
Using any other tire size than what is
specifi ed for the vehicle (page 9-9 )
is dangerous. It could seriously aff ect
ride, handling, ground clearance,
tire clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specifi ed for the
vehicle.

Tire Infl ation Pressure
WARNING
Always infl ate the tires to the correct
pressure:
Overinfl ation or underinfl ation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-9 .

Use only a Mazda-genuine tire valve
cap:
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease which
could result in a serious accident. Do
not use any part for the tire valve cap
that is not a Mazda-genuine part.

Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specifi cation charts (page
9-9 ).
(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 .

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.

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 4-153 .
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 .

Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it is properly
infl ated and stored.
NOTE
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 9-9 .


 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-

WARNING
Do not jack up the vehicle higher than is
necessary:
Jacking up the vehicle higher than
is necessary is dangerous as it could
destabilize the vehicle resulting in an
accident.

Do not start the engine or shake the
vehicle while it is jacked up:
Starting the engine or shaking
the vehicle while it is jacked up is
dangerous as it could cause the vehicle
to fall off the jack resulting in an
accident.

Never go under the vehicle while it is
jacked up:
Going under the vehicle while it is
jacked up is dangerous as it could
result in death or serious injury if the
vehicle were to fall off the jack.

8. Remove the lug nuts by turning them
counterclockwise; then remove the
wheel and center cap.

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

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
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
3. Place the lug wrench on top of the key
and apply pressure. Turn the wrench
