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
Spilled Brake Fluid:
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. Be careful not to spill brake fluid
on yourself or on the engine.
Low Brake/Clutch Fluid Levels:
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 you find a low fluid
level, have the brakes and clutch
inspected.
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
CAUTION
lBrake and clutch fluid will damage
painted surfaces. If brake or clutch
fluid does get on a painted surface,
wash it off with water immediately.
lUsing nonspecified brake and clutch
fluids (page 10-5) 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 10-5).
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.
5AT
CAUTION
lAlways 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.
lA low fluid level can cause transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and transaxle
malfunction.
lUse 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
4AT
The volume of fluid changes with the
temperature. Fluid must be checked at idle
without driving at normal operating
temperature.
CAUTION
lLow fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and transaxle
malfunction.
lUse specified fluid (page 10-5). 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
Sudden Vehicle Movement:
Shifting the shift lever without first
depressing the brake pedal is
dangerous. The vehicle could move
suddenly and cause an accident.
Make sure the brake pedal is applied
before shifting the shift lever.
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
lUse the cold scale only as a
reference.
lIf outside temperature is lower than
about 20°C (70°F), start the engine
and inspect the fluid level after the
engine reaches operating
temperature.
lIf 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 doesn't pass full.
NOTE
Inspect the fluid on both sides of the
dipstick in a well lit area for an accurate
reading.
