*Some models. 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.
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
Ne w tread Tread wear indicator
Worn tread
You should replace the tire before the band
crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 . 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. 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 8-24 .
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.
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 

6 –54 Maintenance and Care
Owner Maintenance
FusesYour 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.
Fuse ReplacementReplacing the fuses on the vehicle's left
side
If the electrical system does not work, first
inspect the fuses on the vehicle's left side.
1. Make sure the ignition is switched off,
and other switches are off.
2. Open the fuse panel cover. 3. Pull the fuse straight out with the
fuse puller provided on the fuse block
located in the engine compartment.
4. Inspect the fuse and replace it if it is
blown.
Normal Blown
5. Insert a new fuse of the same amperage
rating, and make sure it fits tightly. If
it does not fit tightly, have an expert
install it. We recommend 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.
CAUTION Always replace a fuse with a genuine
Mazda fuse or equivalent of the same
rating. Otherwise you may damage
the electric system.
6. Reinstall the cover and make sure that
it is securely installed.

6 –55 Maintenance and Care
Owner MaintenanceReplacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses
in the cabin are normal, inspect the fuse
block under the hood. If a fuse is blown, it
must be replaced. Follow these steps:
1. Make sure the ignition is switched off,
and other switches are off.
2. Remove the fuse block cover.
NOTE
If the lock is forcefully opened, the fuse
block cover may come in contact with the
frame when it is removed and become
scratched.
When removing the cover, remove it slowly
according to the following procedure.
1. Disengage the rear lock by pressing
down on the front tab with your
fingers.
2. Remove the front tab while slightly
lifting the front of the cover. 3. Remove the cover while lifting it and
sliding it to the rear.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of the
same amperage rating .
Normal
Blown
WARNING Do not replace the main fuse and
multiplex slow blow fuse by yourself.
Have an Authorized Mazda Dealer
perform the replacement:
Replacing these fuses by yourself is
dangerous because they are high
current fuses. Incorrect replacement
could cause an electrical shock or a
short circuit resulting in a fire.
4. Reinstall the cover and make sure that
it is securely installed.
