5. Check the coolant level.
If it’s low, look for leaks in the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump.
If you find a leak or other damage, or if
coolant is still leaking, stop the engine
and call an Authorized Mazda Dealer.
If you find no problems, the engine is
cool, and no leaks are obvious, carefully
add coolant as required (page 8-13).

Cooling System Caps:When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don’t remove either
cooling system cap when the engine
and radiator are hot.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made.

1. Make sure the booster battery is 12 V
and that its negative terminal is
grounded.
2. If the booster battery is in another
vehicle, don’t allow the vehicles to
touch. Turn off the engine of the
vehicle with the booster battery and all
unnecessary electrical loads in both
vehicles.
3. Connect the jumper cables in the exact
sequence as in the illustration.
Connect one end of a cable to the
positive terminal on the discharged
battery (1).
Attach the other end to the positive
terminal on the booster battery (2).
Connect one end of the other cable
to the negative terminal of the
booster battery (3).
Connect the other end to a solid,
stationary, exposed metallic point
(for example, the strut mounting
bolt) away from the discharged
battery (4).4. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
5. When finished, carefully disconnect
the cables in the reverse order
described in Step 3.

batteryJumper cables
Connect cables in
numerical order and
disconnect in reverse
order.
Connecting to Negative Terminal:Connecting the end of the second
cable to the negative ( ) terminal of
the discharged battery is dangerous.
A spark could cause the gas around
the battery to explode and injure
someone. Connect the cable to a point
away from the battery.
Connecting Jumper Cable to a
Moving Part:Connecting a jumper cable near or to
a moving parts (cooling fans, belts) is
dangerous. The cable could get
caught when the engine starts and
cause serious injury. Never connect a
jumper cable to or near any part that
moves.

Maintenance and Care
Owner Maintenance
Form No. 8R29-EA-02I
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 procedure 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.
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 procedure. 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, with 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.

Inspecting Coolant Level
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 or F and
LOW or L marks on the coolant reservoir
when the engine is cool.If it’s at or near LOW or L, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL or F.
Do not overfill.

If new coolant is required frequently,
consult an Authorized Mazda Dealer.
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. Don’t
inspect the coolant system or add
coolant when the engine is hot.
WARNING
2.3-liter engine
Radiator coolant will damage paint.
Rinse it off quickly.

Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
For mixture percentage:To change coolant
1. Remove the cooling system cap. •
Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant’s effectiveness.
•
Don’t add only water. Always add a
proper coolant mixture.
•
The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
•
DO NOT USE alcohol or methanol
antifreeze. DO NOT MIX alcohol
or methanol with the coolant. This
could damage the cooling system.
•
Don’t use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

CAUTIONRemoving the Cooling System Cap:Removing the cooling system cap or
drain plug while the engine is
running or hot is dangerous. This
might lead to cooling system and
engine damage and could result in
serious injury from escaping hot
coolant or steam. Turn off the engine
and wait until it’s cool. Even then, be
very careful when removing the cap
or drain plug. Wrap a thick cloth
around it and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you’re sure all the pressure is
gone, press down on the cap — still
using a cloth — turn the cap, and
remove it.
