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

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.

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.
NOTE
Be sure to install the tire pressure
sensors whenever tires or wheels are
replaced. (page 5-24)

Your Mazda’s headlights and fog lights
have replaceable halogen bulbs.
Replacing Exterior Light Bulbs
Replacing a headlight bulb
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood.
3. Do the following procedure when
replacing the left headlight bulb.
Turn the screws counterclockwise and
remove them and the cover.
4. 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.
(page 8-36)
Xenon Fusion Bulb Replacement:
Replacing the xenon fusion bulbs by
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Do not replace the xenon
fusion bulbs by yourself. Consult an
Authorized Mazda Dealer when the
replacement is necessary.
Handling Halogen 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.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.
