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.

| Normal fuse, Blown fuse |
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.

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.

| 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.
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.
