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.
Turn off the ignition switch 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 or F and
MIN or L marks on the coolant reservoir
when the engine is cool.
Without turbocharger
With turbocharger
If it's at or near MIN or L, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to MAX or F.

CAUTION
ØRadiator coolant will damage
paint.
Rinse it off quickly if spilled.
Ø Use only soft (demineralized)
water in the coolant mixture.
Water that contains minerals will
cut down on the coolant's
effectiveness.
Ø Don't add only water. Always add
a proper coolant mixture.
Ø The engine has aluminum parts
and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.
Ø DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
Ø DO NOT MIX alcohol or methanol
with the coolant. This could
damage the cooling system.
Ø Don'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.
Without turbocharger
With turbocharger
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
Ø Brake and clutch fluid will
damage painted surfaces. If brake
or clutch fluid does get on a
painted surface, wash it off with
water immediately.
Ø Using 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.

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.
Without turbocharger
With turbocharger
The level must be kept between MIN and
MAX.

Automatic Transaxle Fluid
(ATF)
í
qInspecting Automatic Transaxle
Fluid Level
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
5AT
CAUTION
Ø Always 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.
Ø A low fluid level can cause
transaxle slippage. Overfilling can
cause foaming, loss of fluid, and
transaxle malfunction.
Ø Use 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

The volume of fluid changes with
temperature. Fluid must be checked while
idling the engine without driving at
normal operating temperature.
CAUTION
ØLow fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and
transaxle malfunction.
Ø Use specified fluid (page 10-4). A
nonspecified fluid could result in
transaxle malfunction and failure.
1. Park on a level surface and set the parking brake firmly.
2. Start the engine and depress the brake pedal.
3. Move the shift lever through all ranges, then set it at P.
WARNING
Make sure the brake pedal is applied
before shifting the shift lever: Shifting the shift lever without first
depressing the brake pedal is
dangerous. The vehicle could move
suddenly and cause an accident.
4. With the engine still idling, pull out the dipstick, wipe it clean, and put it back. 5. Pull it out again.
The proper fluid level is marked on the
dipstick as follows.
A
Full
Low
B
Full
Fluid hot scale A
When the vehicle has been driven and the
fluid is at normal operating temperature,
about 65°C (150°F), the level must be
between Full and Low.
Fluid cold scale B
When the engine has not been running
and the outside temperature is about 20°C
(70°F), the fluid level should be close to,
but not above, the bottom notch on the
dipstick.
CAUTION
Ø
Use the cold scale only as a
reference.
Ø If outside temperature is lower
than about 20°C (70°F), start the
engine and inspect the fluid level
after the engine reaches operating
temperature.
Ø If 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.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
To inspect the washer fluid level in the
front reservoir, pull off the cap. Then,
holding your thumb over the hole in the
center of the cap, lift it straight up. The
fluid level can be seen from the fluid
column in the pipe. Add fluid if necessary.
Use plain water if washer fluid is
unavailable. But use only washer fluid in
cold weather to prevent it from freezing.
NOTE
Front and rear washer fluid 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.

3. Turn the knobs counterclockwise andlower the fuse block.
4. Locate the position of the suspected
fuse by using the chart inside the fuse
block cover.
5. Pull the fuse straight out with the fuse puller provided on the inside of the
engine compartment fuse block cover.
6. Inspect the fuse and replace it if it'sblown.
Normal Blown
7. Insert a new fuse of the same amperage
rating, and make sure it fits tightly. If it
does not fit tightly, have an expert
install it. We recommend an
Authorized Mazda Dealer.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the MIRROR or CIGAR circuit.
CAUTION
Always replace a fuse with one of the
same rating. Otherwise you may
damage the electric system.
Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses in
the cabin are normal, inspect the fuse
block under the hood. If a fuse is blown, it
must be replaced. Follow these steps:
1. Turn off the ignition switch and allother switches.
