Fuses  
Your vehicle's electrical system is  
protected by fuses.  
located in the engine compartment.  
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.  
4. Inspect the fuse and replace it if it is  
blown.  
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.

Normal  
1. Make sure the ignition is switched off,  
and other switches are off.  
2. Open the fuse panel cover.  
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.  
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  
3. Remove the cover while lifting it  
and sliding it to the rear.  
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.  
NOTE  
If the lock is forcefully opened, the fuse  
block cover may come in contact with  
the frame when it is removed and  
become scratched.  
When removing the cover, remove it  
slowly according to the following  
procedure.  
1. Disengage the rear lock by  
pressing down on the front tab with  
your fingers.  
Normal  
Blown  
2. Remove the front tab while slightly  
lifting the front of the cover.  
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  
ꢀre.  
4. Reinstall the cover and make sure that  
it is securely installed.
