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:
Working near the electrical cooling fan when it is running is dangerous. You could be
hit by the fan and seriously injured. Turn off the ignition switch and make sure the
fan is not running before attempting to work near the electrical cooling fan.

NOTE
Once the engine coolant exceeds a preset temperature, an electrical cooling fan turns on.
It will continue running for about 10 minutes after the ignition switch is turned to off.

Check the oil level and fill to the F mark
if necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
NOTE
lThe indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
lUse only specified engine oil (page
10-4).
lVerify that the engine cover is
securely installed.

Because you need a special tool to
retighten the filter, an Authorized Mazda
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.
Electrical Fan and Engine
Inspection:
Working near the electrical cooling
fan when it is running is dangerous.
You could be hit by the fan and
seriously injured. Turn off the ignition
switch and make sure the fan is not
running before attempting to work
near the electrical cooling fan.
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.

NOTE
Once the engine coolant exceeds a
preset temperature, an electrical cooling
fan turns on. It will continue running
for about 10 minutes after the ignition
switch is turned to off.
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 F and L marks
on the coolant reservoir when the engine
is cool.
If it's at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
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.
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 alcohol or methanol
antifreeze. DO 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.

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.
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.
1. Remove the cooling system cap.
2. Only when the engine is cool, loosen
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.3. With the drain plug loose but not fully
removed, flush out the system with
running water.
Tighten Loosen Loosen

4. Drain the system completely and
retighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water as necessary to provide
freezing and corrosion protection.
5. In extremely cold climates, add the
mixture percentage recommended in
the coolant mixture percentage table.
6. Reinstall the cooling system cap.
7. Run the engine at idle for about 10
minutes, then turn it off. If the coolant
level warning light comes on during
this time, turn the engine off.
After turning off the engine, inspect the
drain plug and the water hoses for
leaks.
8. After the engine has cooled, remove
the cooling system cap and inspect the
coolant level. If it's low, repeat steps 5
to 7.
