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.

Dealer should do the work.
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 EngineInspection:
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 or F and
LOW or L marks on the coolant reservoir
when the engine is cool.
2.3-liter engine
3.0-liter engine
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.
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
qChanging Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
CAUTION
lUse only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
lDon't add only water. Always add a
proper coolant mixture.
lThe engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
lDO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
lDO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
lDon't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.

NOTE
If the“FL22”mark is shown on or near
the cooling system cap, use FL22 type
engine coolant. If engine coolant other
than FL22 type is used, the engine
coolant must be replaced earlier than
the specified replacement interval
indicated in the scheduled maintenance
(page 8-3).

WARNING
Removing the Cooling System Cap:
Removing the cooling system cap
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.
Wrap a thick cloth around the cap and
slowly turn it counterclockwise to the
first stop (3.0-liter engine) or about
two and a half rotations (2.3-liter
engine).
Step back while the pressure escapes.
When you're sure all the pressure is
gone, press down on the cap (3.0-liter
engine)―still using a cloth―turn
the cap, and remove it.
1. Make sure the engine is not running
and it has cooled.
2. Remove the cooling system cap.

3. Remove the radiator drain plug and
drain the coolant into a suitable
container. Properly dispose of the used
coolant.
4. Flush out the system with running
water.
5. Drain the system completely. Insert and
tighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water as necessary to provide
freezing and corrosion protection.
6. In extremely cold climates, add the
mixture percentage recommended in
the coolant mixture percentage table.
7. Run the engine at idle with the cooling
system cap off. Slowly add additional
coolant if necessary.
8. At this point, wait until the engine
reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
9. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time and verify that the coolant level is
between the F and L marks.
Brake/Clutch Fluid
qInspecting Brake/Clutch Fluid Level
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept at MAX.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
