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.

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
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.

CAUTION
ØDon't use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodized aluminum parts. This
may damage the protective
coating; also, cleaners and
detergents may discolor or
deteriorate the paint.
ØTo prevent damaging the antenna,
remove it before entering a car
wash facility or passing beneath a
low overhead clearance.
Pay special attention to removing salt,
dirt, mud, and other foreign material from
the underside of the fenders, and make
sure the drain holes in the lower edges of
the doors and rocker panels are clean.
Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits can
damage the finish if not removed
immediately. When prompt washing with
plain water is ineffective, use a mild soap
made for use on vehicles.
Thoroughly rinse off all soap with
lukewarm or cold water. Don't allow soap
to dry on the finish.
After washing the vehicle, dry it with a
clean chamois to prevent water spots from
forming.
WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal:
Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
Waxing
Your vehicle needs to be waxed when
water no longer beads on the finish.
Always wash and dry the vehicle before
waxing it. In addition to the vehicle body,
wax the metal trim to maintain its luster.
1. Use wax which contains no abrasives.
Waxes containing abrasive will remove
paint and could damage bright metal
parts.
2. Use a good grade of natural wax for
metallic, mica, and solid colors.
3. When waxing, coat evenly with the
sponge supplied or a soft cloth.
4. Wipe off the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and similar
materials will usually also take off the wax.
Rewax these areas even if the rest of the
vehicle doesn't need it.
