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.
