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.
Visually examine the lines and hoses for
leaks and damage.
If new fluid is required frequently, consult
an Authorized Mazda Dealer.

Automatic Transaxle Fluid

í
qInspecting Automatic Transaxle
Fluid Level
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
5AT
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.

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.
ØUse 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
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.

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 and
lower 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's
blown.
NormalBlown
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 all
other switches.
