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.
qFuse Replacement
Replacing 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.
NormalBlown
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.
Replacing 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.
