Fuses
▼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 expert
repairer (we recommend an
Authorised Mazda Repairer) as soon as
possible.
▼Fuse 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.
1. Normal
2. 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. Consult an
expert repairer (we recommend an
Authorised Mazda Repairer).
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
accessory socket 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 bonnet
If the headlights or other electrical
components do not work and the fuses
in the cabin are normal, inspect the
fuse block under the bonnet.
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.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of
the same amperage rating.
1. Normal
2. Blown

WARNING
Do not replace the main fuse by
yourself. Have an expert repairer
(we recommend an Authorised
Mazda Repairer) perform the
replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse
is a high current fuse. 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.
