Black plate (425,1)
NOTElAlways check tire pressure when tires are
cold.
lWarm tires normally exceed recommended
pressures. Don't release air from warm tires
to adjust the pressure.
lUnderinflation 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.
lOverinflation 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 inflating,
have it inspected.
qTire 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 according to
the scheduled maintenance charts.
Refer to Scheduled Maintenance on
page 8-3. 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:
lIncorrect tire pressurelImproper wheel alignmentlOut-of-balance wheellSevere braking
After rotation, inflate all tire pressures to
specification (page 10-11) and inspect the
lug nuts for tightness.
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.

CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
q 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.
CAUTION
(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)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-35.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-35.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New tread
Tread wear indicator
Worn tread
You should replace the tire before the
band crosses the entire tread.
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 9-24.

qTemporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
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.
Maintain its pressure at 420 kPa (4.2
kgf/cm
2or bar, 60 psi).
CAUTION
Ø Do not 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.
Ø 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.
Ø 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 8-40). 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 9-24.
q
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 affected, leading to loss of
control and an accident.

ØLimited-Slip Differential System
Ø (With Tire Pressure Monitoring
System)
ØWhen 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.
ØThe wheels equipped on your
Mazda are specially designed
for installation of the tire
pressure sensors. Do not use
non-genuine wheels, otherwise
it may not be possible to install
the tire pressure sensors.
NOTE
Be sure to install the tire pressure sensors
whenever tires or wheels are replaced. Refer to
Tires and Wheels on page 5-35.
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). 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 flat 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 flying 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.
qReplacing Exterior Light Bulbs
NOTElTo replace the bulb, contact an Authorized
Mazda Dealer.
lIf the halogen bulb is accidentally touched,
it should be cleaned with rubbing alcohol
before being used.
lUse the protective cover and carton for the
replacement bulb to dispose of the old bulb
promptly and out of the reach of children.
