Engine Oil
NOTE
Changing the engine oil should be done by an
Authorized Mazda Dealer.
qRecommended Oil
Use SAE 5W-20 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.
U.S.A. and CANADA
(ILSAC)
Only use oils“Certified For Gasoline
Engines”by the American Petroleum
Institute (API). An oil with this trademark
symbol conforms to the current engine
and emission system protection standards
and fuel economy requirements of the
International Lubricant Standardization
and Approval Committee (ILSAC),
comprised of U.S. and Japanese
automobile manufacturers.

qInspecting 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.
Full
OK
Low
5. Pull it out again and examine the level.
It's OK between Low or MIN and Full
or MAX.
But if it's near or below Low or MIN,
add enough oil to bring the level to
Full or MAX.
CAUTION
Don't add engine oil over Full or
MAX. This may cause engine
damage.
6. Make sure the O-ring on the dipstick is
positioned properly before reinserting
the dipstick.
The distance between Low or MIN and
Full or MAX on the dipstick represents
the following:

Engine Coolant
qInspecting Coolant Level
WARNING
Do not use a match or live flame 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.
Switch the ignition to 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 indefinitely
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 the 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.
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 MAX and MIN
marks on the coolant reservoir when the
engine is cool.
If it's at or near MIN, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to MAX.

CAUTION
ØRadiator coolant will damage
paint.
Rinse it off quickly if spilled.
ØUse only soft (demineralized)
water in the coolant mixture.
Water that contains minerals will
cut down on the coolant's
effectiveness.
ØDon't add only water. Always add
a proper coolant mixture.
ØThe engine has aluminum parts
and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.
ØDO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
ØDO NOT MIX alcohol or methanol
with the coolant. This could
damage the cooling system.
ØDon'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).
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

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.
qAdding Brake/Clutch Fluid
WARNING
Be careful not to spill brake fluid on
yourself or on the engine:
Spilled brake fluid is dangerous. If it
gets in your eyes, they could be
seriously injured. If this happens,
immediately flush your eyes with
water and get medical attention.
Brake fluid spilled on a hot engine
could cause a fire.
If the brake/clutch fluid level is low,
have the brakes and clutch inspected:
Low brake/clutch fluid levels are
dangerous. Low levels could signal
brake lining wear or a brake system
leak. Your brakes could fail and
cause an accident.
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
CAUTION
ØBrake and clutch fluid will
damage painted surfaces. If brake
or clutch fluid does get on a
painted surface, wash it off with
water immediately.
ØUsing nonspecified brake and
clutch fluids (page 10-4) will
damage the systems. Mixing
different fluids will also damage
them.
If the brake/clutch system
frequently requires new fluid,
consult an Authorized Mazda
Dealer.

Power Steering Fluid
qInspecting Power Steering Fluid
Level
CAUTION
To avoid damage to the power
steering pump, don't operate the
vehicle for long periods when the
power steering fluid level is low.
NOTE
Use specified power steering fluid (page 10-4).
Inspect the fluid level in the reservoir at
each engine oil change with the engine off
and cold. Add fluid if necessary; it does
not require periodic changing.
The level must be kept between MIN and
MAX.
Visually examine the lines and hoses for
leaks and damage.
If new fluid is required frequently, consult
an Authorized Mazda Dealer.
Automatic Transaxle Fluid
(ATF)
í
qInspecting Automatic Transaxle
Fluid Level
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
CAUTION
ØAlways check the automatic
transaxle fluid level according to
the following procedure. If the
procedure is not done correctly,
the automatic transaxle fluid level
cannot be measured accurately
which could lead to automatic
transaxle damage.
ØA low fluid level can cause
transaxle slippage. Overfilling can
cause foaming, loss of fluid, and
transaxle malfunction.
ØUse only the specified fluid. A non-
specified fluid could result in
transaxle malfunction and failure.
1. Park on a level surface and set the
parking brake firmly.
2. Make sure there is no ATF leakage
from the ATF hose or the housing.
3. Shift the shift lever to the park position
(P), start the engine and warm it up.
CAUTION
Do not shift the shift lever while the
engine is warming up. If the ATF level
is extremely low, the automatic
transaxle could be damaged.

4. While the engine is still idling, pull out
the dipstick and wipe it clean, and then
put it back.
5. Check the ATF level. If there is no ATF
adhering 5 mm from the end of the
dipstick, add ATF.
CAUTION
If there is no ATF adhering to the
dipstick even after the engine has
been warmed up, do not drive the
vehicle. Otherwise, the automatic
transaxle could be damaged.
6. Shift the shift lever to each range and
position, and make sure there is no
abnormality.
7. Drive the vehicle on city roads for
5 km (3.1 mile) or more.
8. Park on a level surface and set the
parking brake firmly.
9. Shift the shift lever to the park position
(P), check the ATF level while the
engine is idling, and make sure that the
ATF level is within the proper level. If
the ATF level is not within the proper
level, add ATF. The proper fluid level
is marked on the dipstick as follows.
Full
OK
Low
CAUTION
ØUse the cold scale only as a
reference.
ØIf outside temperature is lower
than about 20°C (70°F), start the
engine and inspect the fluid level
after the engine reaches operating
temperature.
ØIf the vehicle has been driven for
an extended period at high speeds
or in city traffic in hot weather,
inspect the level only after
stopping the engine and allowing
the fluid to cool for 30 minutes.
Fully insert the dipstick. When adding
fluid, inspect with the dipstick to make
sure it does not pass full.
NOTE
Inspect the fluid on both sides of the dipstick in
a well lit area for an accurate reading.
