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 .

2. Blown

WARNING
Do not replace the main fuse by
yourself. Have an Authorized Mazda

shock or a short circuit resulting in a
fire.
4. Reinstall the cover and make sure that it is securely installed.
