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 9-7.

CAUTION
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.
 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-band indicator appears, replace the
tire with the same type of temporary
spare (page 6-36).
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 8-25.
▼ Replacing a Wheel
WA R N I N G
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
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
*
NOTE
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).
For details, contact an Authorized
Mazda Dealer.

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.

Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate circuit
protector. If a fuse has blown, the inside
element will be melted.

If the same fuse blows again, avoid using
that system and consult an Authorized
Mazda Dealer as soon as possible.

amperage rating, and make sure it fits
tightly. If it does not fit tightly, have an
expert install it. Co nsult an Authorized
Mazda Dealer.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the AUDIO or OUTLET circuit.

Mazda fuse or equivalent of the same
rating. Otherwise you may damage the
electric system.
