2021 MAZDA MODEL CX-3 fuse

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.
▼ 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 isblown.
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. Consult 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.
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 by
yourself. Have an Authorized Mazda
Dealer 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.
