CAUTION
Limited-Slip Differential system;
don't use the following:
lTires not of the designated size
lTires of different sizes or types at the
same time
lTires 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.
qReplacing 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.
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 5-30.
lBe sure to install the tire pressure
sensors whenever tires or wheels are
replaced.
Refer to Tires and Wheels on page
5-30.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

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. Regarding the manufacturing
week and year is indicated with 4 digit.
Refer to The tire labeling on page 9-18.
qTemporary Spare Tire
Your Mazda is not equipped with a spare
tire. If you require a spare tire, consult an
Authorized Mazda Dealer.
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. 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
2or bar, 60 psi).
CAUTION
lDon'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.
lThe 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.
lThe 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 8-26).
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. Regarding the manufacturing

qReplacing 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.
CAUTION
lA wrong-sized wheel may adversely
affect:
lTire fitlWheel and bearing lifelGround clearancelSnow-chain clearancelSpeedometer calibrationlHeadlight aimlBumper heightlTire Pressure Monitoring SystemlLimited-Slip Differential System
l(With Tire Pressure Monitoring
System)
lWhen 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.
lThe 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 5-30.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
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 a Headlight Bulb
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood and find the high and low
beam bulbs in the rear of the headlight
unit.
The outboard bulb is the LOW beam,
and the inboard one is the HIGH beam.
Refer to Light Bulbs on page 8-29.
3. If you are changing the right headlight
bulb, start the engine, turn the steering
wheel all the way to the right, and turn
off engine. If you are changing the left
headlight bulb, turn the steering wheel
to the left.
4. Turn the center section of the plastic
retainer counterclockwise and remove
the retainers and partially peel back the
mudguard.
