Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
WARNING
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.
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.If the temperature gauge indicates
overheating:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
Apply the parking brake.
3. Turn off the air conditioner.
4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don't go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
5. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
6. When cool, check the coolant level.
If it's low, look for coolant leaks from
the radiator and hoses.

Starting a Flooded Engine
If the engine fails to start, it may be
flooded (excessive fuel in the engine).
Follow this procedure:
1. Depress the accelerator all the way and
hold it there.
2. Turn the ignition switch to the START
position and hold it there―for up to 10
seconds. If the engine starts, release the
key and accelerator immediately
because the engine will suddenly rev
up.
3. If the engine fails to start, crank it
without depressing the accelerator―for
up to 10 seconds.
Jump-Starting
The battery is in the trunk.
Jump-starting is dangerous if done
incorrectly. So follow the procedure
carefully. If you feel unsure about jump-
starting, we strongly recommend that you
have a competent service technician do
the work.
WARNING
Battery-Related Explosion:
Flames and sparks near open battery
cells are dangerous. Hydrogen gas,
produced during normal battery
operation, could ignite and cause the
battery to explode. An exploding
battery can cause serious burns and
injuries. Keep all flames, including
cigarettes, and sparks away from open
battery cells.
Frozen Battery:
Jump-starting a frozen battery is
dangerous. It may rupture or explode,
causing serious injury.
Don't jump-start a frozen battery.
CAUTION
Use only a 12 V booster system. You
can damage a 12 V starter, ignition
system, and other electrical parts
beyond repair with a 24 V power
supply (two 12 V batteries in series or a
24 V motor generator set).
1. Make sure the booster battery is 12 V
and that its negative terminal is
grounded.

Owner Maintenance Precautions
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
Mazda Dealer.
WARNING
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.

Engine Coolant
qInspecting Coolant Level
WARNING
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.Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.
If it's at or near LOW, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.

Your Mazda's headlights and fog lights
have replaceable halogen bulbs.
WARNING
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.
qReplacing 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 and 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.
Refer to Light Bulbs (page 8-33).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.
