Fuses
Your vehicle's electrical system is
protected by fuses.
If any lights, accessories, or controls don't
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.
qFuse 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. Remove the cover.
3. Pull the fuse straight out with the fuse puller provided on the inside of the
engine compartment fuse block cover.
4. Inspect the fuse and replace it if it'sblown.
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. 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 CIGAR circuit.
CAUTION
Always replace a fuse with one of the
same rating. Otherwise you may
damage the electric system.

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.
