Improper or incomplete service may result in problems. This section gives instructions
only for items that are easy to perform.
As explained in the Introduction (page 8-2), several procedures can be done only by a
qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage.
For details, read the separate Mazda Warranty statement provided with the vehicle. If
you’re unsure about any servicing or maintenance procedure, have it done by an
Authorized Mazda Dealer.
There are strict environmental laws regarding the disposal of waste oil and fluids. Please
dispose of your waste properly and with due regard to the environment.
We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized

Owner Maintenance Precautions
Maintenance Procedures:
Performing maintenance work on a vehicle is dangerous if not done properly. You can
be seriously injured while performing some maintenance procedures. If you lack
sufficient knowledge and experience or the proper tools and equipment to do the
work, have it done by a qualified technician.
Running the Engine:
Working under the hood with the engine running is dangerous. It becomes even more
dangerous when you wear jewelry or loose clothing.
Either can become entangled in moving parts and result in injury.
Therefore, if you must run the engine while working under the hood, make certain
that you remove all jewelry (especially rings, bracelets, watches, and necklaces) and
all neckties, scarves, and similar loose clothing before getting near the engine or
cooling fan which may turn on unexpectedly.
Electrical Fan and Engine Inspection:
Inspecting the engine with the ignition switch in the ON position is dangerous. The
cooling fan could come on unexpectedly even when the engine isn’t running. You
could be seriously injured by the fan. Turn the ignition switch off and remove the key
from the ignition switch when you inspect the engine.

Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
NOTE
•The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
•Use only specified engine oil (page
10-4).
Engine Coolant
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Do not use a match or live flame in
the engine compartment. DO NOT
ADD COOLANT WHEN THE
ENGINE IS HOT.
Cooling Fan and Engine
Inspection:
Inspecting the engine with the
ignition switch in the ON position is
dangerous. The cooling fan could
turn on unexpectedly even when the
engine isn’t running. You could be
seriously injured by the fan. Turn the
ignition switch off and remove the key
from the ignition switch when you
inspect the engine.
Cooling System Cap:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don’t remove the
cooling system cap when the engine
and radiator are hot.

Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.
If the blades are not wiping properly,
clean the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.

Replacing Windshield Wiper
Blades
When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.
1. Raise the wiper arm and turn the blade
assembly to expose the plastic locking
clip.
Slide the assembly downward; then lift
it off the arm.
Wiper Blades
•Hot waxes applied by automatic car
washers have been known to affect
the cleanability of windows.
•To prevent damage to the wiper
blades, don’t use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
•When the wiper lever is in the
AUTO position and the ignition
switch is in the ON position, the
wipers may move automatically in
the following cases:
If the windshield above the rain
sensor is touched.
If the windshield above the rain
sensor is wiped with a cloth.
If the windshield is given a
shock.
If the rain sensor is given a shock
from inside the vehicle.
Be careful not to pinch hands or
fingers as it may cause injury, or
damage the wipers. When washing or
servicing your Mazda, make sure the
wiper lever is in the OFF position.
CAUTION
To prevent damage to the wiper arms
and other components, don’t move the
wipers by hand.
To prevent damage to the windshield,
don’t let the wiper arm fall on it.

Your Mazda’s headlights and fog lights
have replaceable halogen bulbs.
Replacing Exterior Light Bulbs
Replacing a headlight bulb
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood.
3. Do the following procedure when
replacing the left headlight bulb.
Turn the screws counterclockwise and
remove them and the cover.
4. Find the high and low beam bulbs in
the rear of the headlight unit.
The outboard bulb is the LOW beam,
and the inboard one is the HIGH beam.
(page 8-36)
Xenon Fusion Bulb Replacement:
Replacing the xenon fusion bulbs by
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Do not replace the xenon
fusion bulbs by yourself. Consult an
Authorized Mazda Dealer when the
replacement is necessary.
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.

6. Inspect it and replace if it’s blown.
7. 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 SPARE circuit.

components don’t work and the fuses in
the cabin are OK, inspect the fuse block
under the hood. If a fuse is blown, it must
be replaced. Follow these steps:
1. Turn off the ignition switch and all
other switches.2. Remove the fuse block cover.
3. If a fuse is blown, replace it with a new
