Your Mazda’s headlights have replaceable
halogen bulbs.
Replacing a Headlight Bulb
1. Make sure the headlight switch is off.
2. Lift the hood and find the high and low
beam bulbs in the rear of the headlight
body.
The outboard bulb is the LOW beam,
and the inboard one is the HIGH beam.
3. Turn the socket and bulb assembly counterclockwise and remove it while
holding the rubber socket cover in
place. Carefully remove the headlight
bulb from its socket in the reflector by
gently pulling it straight backward out
of the socket.
4. Disconnect the bulb from the electrical connector by pressing the tab on the
connector with your finger and pulling
the bulb upward.
Handling Halogen Bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it
will explode and serious injuries
could be caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.

Yo u r v e h i c l e’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.

Fuse Replacement
If the electrical system doesn
’t work, first
inspect fuses on the driver ’s side.
1. Turn off the ignition switch and other switches.
2. Open the fuse panel cover. 3. Pull the fuse straight out with the fuse
puller provided on the fuse panel.
4. Inspect it and replace if it ’s blown.
5. Push in a new fuse of the same rating, and make sure it fits tightly. If it
doesn ’t, have an Authorized Mazda
Dealer install it.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the RADIO circuit.
Fuses
Fuse panel cover
Always replace a fuse with one of the
same rating. Otherwise you may
