This air filter may be cleaned with
compressed air and reused, or replaced,
depending on its condition. Unless it is
very dirty, simply shake it to remove
foreign particles. Each time you inspect it,
wipe inside the air cleaner housing with a
damp cloth.

Replacing the Air Filter
1. Make sure the ignition switch is turned
off.
2. Remove the battery cover and battery duct. 3. Unfasten the clamps.
4. Lift off the air filter cover and remove
the filter.
5. Wipe inside the air cleaner housing with a damp cloth.
6. Clean or replace the filter.
7. Install in the reverse order of removal.
Replace the filter according to the
Scheduled Maintenance (page 8-3).
Air Filter
Don ’t drive without an air filter. This
could result in excessive engine wear.
NOTE
If the vehicle is operated in very dusty
or sandy areas, replace the filter more
often than the recommended intervals.
Use a Mazda genuine air filter. Use of
other filters could damage the airflow
sensor.

Tire Rotation
To equalize tread wear, rotate the tires
every 12,000 km (7,500 miles)/8,000 km*
(5,000 miles) or sooner if irregular wear
develops. During rotation, inspect them
for correct balance.
*Unique driving conditions for USA,
Canada and Puerto Rico
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, inflate all tire pressures to
specification (page 10-8) and inspect the
lug nuts for tightness.
NOTE
• Always check tire pressure when
tires are cold.
• Warm tires normally exceed
recommended pressures. Don
’t
release air from warm tires to adjust
the pressure.
• Underinflation can cause reduced
fuel economy and poor sealing of
the tire bead, which will deform the
wheel and cause separation of tire
from rim.
• Overinflation can produce a harsh
ride and a greater possibility of
damage from road hazards.
Keep your tire pressure at the
correct levels. If one frequently
needs inflating, have it inspected.
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.
Front
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.

Replacing a TireIf a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
You should replace it before the band is
across the entire tread.

Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it
’s properly
inflated and stored.
The temporary spare tire is easier to
handle because of its construction. It is
lighter and smaller than a conventional
tire and should be used only for an
emergency and only for a short distance.
Use the temporary only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2 kgf/
cm
2 or bar, 60 psi).
Worn Tires:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Always use tires that are in good
condition.
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the
tire pressure sensors may be damaged.
NOTE
(With Tire Pressure Monitoring
System)
• When tires with steel wire
reinforcement in the sidewalls are
used, the system may not function
correctly even with a genuine
wheel. (page 5-24)
• Be sure to install the tire pressure
sensors whenever tires or wheels are
replaced. (page 5-24)

Replacing a Wheel
• Don
’t 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 up to 5,000 km (3,000 miles),
depending on road conditions and
driving habits.
• 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 8-33).
CAUTION
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.
•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
• (With Tire Pressure Monitoring
System)

 When replacing/repairing the
tires or wheels or both, have the
work done by an Authorized
Mazda Dealer, or the tire
pressure sensors may be
damaged.
 The wheels equipped on your
Mazda are specially designed for
installation the tire pressure
sensors. Do not use non-genuine
wheels, otherwise it may not be
possible to install the tire
pressure sensors.
