WARNING
Do not perform maintenance work if you lack suffi cient knowledge and experience
or the proper tools and equipment to do the work. Have maintenance work done by a
qualifi ed technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can be
seriously injured while performing some maintenance procedures.
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 lo ose clothing before getting near the engine or cooling
fan which may turn on unexpectedly: 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.
Pull over to a safe location, then switch the ignition off and make sure the fan is not
running before attempting to work near the cooling fan: Working near the cooling fan when it is running is dangerous. The fan could continue
running indefi nitely even if the engine has stopped and the engine compartment
temperature is high. You could be hit by the fan and seriously injured.
Do not leave items in the engine compartment: After you have fi nished checking or doing servicing in the engine compartment, do not
forget and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine compartment could cause engine damage or a fi re
leading to an unexpected accident.

Except U.S.A. and CANADA
Use SAE 5W-30 engine oil.
Oil container labels provide important
information.
A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine friction.

Vehicle Engine Control Unit Reset
Procedure
After replacing the engine oil, it is
recommended to have a repair shop such
as an Authorized Mazda Dealer perform
the initialization (engine oil data resetting)
of the recorded value. If the value recorded
by the computer is not initialized, the
wrench indicator light may not turn off or
it may turn on earlier than normal.
Refer to Maintenance Monitor on page
6-16 .

Inspecting Engine Oil Level
1. Be sure the vehicle is on a level surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and reinsert it fully.
MAXOK
MIN
5. Pull it out again and examine the level.
The level is normal if it is between the MIN and MAX marks.
If it is near or below MIN, add enough oil to bring the level to MAX.
CAUTION
Do not overfi ll the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live fl ame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT: 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.
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before attempting
to work near the cooling fan: Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefi nitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and
radiator are hot: When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.

Maintenance and Care
Owner Maintenance
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 is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
Radiator coolant will damage paint. Rinse it off quickly if spilled. If the “FL22” mark is shown on or near the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other
than FL-22 may cause serious damage to
the engine and cooling system.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

Inspect fl uid level in the washer fl uid
reservoir; add fl uid if necessary.
L F
OK
The top of the fl oat should be between F
and L.
Use plain water if washer fl uid is
unavailable.
But use only washer fl uid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fl uid is supplied
from the same reservoir.
Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
