To change coolant1. Remove the cooling system cap.
2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.
3. Flush out the system with running
water.
4. Drain the system completely. Insert
and tighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water as necessary to provide
freezing and corrosion protection.
5. In extremely cold climates, add the
mixture percentage recommended in
the coolant mixture percentage table.
6. Run the engine at idle with the cooling
system cap off. Slowly add additional
coolant if necessary.
7. At this point, wait until the engine
reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
8. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time.
Removing the Cooling System Cap:
Removing the cooling system cap
while the engine is running or hot is
dangerous. This might lead to cooling
system and engine damage and could
result in serious injury from escaping
hot coolant or steam. Turn off the
engine and wait until it’s cool. Even
then, be very careful when removing
the cap.
Wrap a thick cloth around the cap
and slowly turn it counterclockwise
about two and a half rotations.
Step back while the pressure escapes.
When you’re sure all the pressure has
escaped, turn the cap
counterclockwise — still using a cloth
— and remove the cap.

Inspecting 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.

Adding Brake/Clutch Fluid
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
Brake/Clutch Fluid
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.

Inspecting Power Steering Fluid
Level
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. •Brake and clutch fluid will damage
painted surfaces. If brake or clutch
fluid does get on a painted surface,
wipe it off immediately.
•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.
CAUTIONPower Steering Fluid
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).

Inspecting Automatic Transaxle
Fluid Level
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
The volume of fluid changes with the
temperature. Fluid must be checked at idle
without driving at normal operating
temperature.
1. Park on a level surface and set the
parking brake firmly.
2. Idle the engine about two minutes.
Push down on the brake pedal.
3. Move the shift lever through all ranges
and set it at P.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.
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 level must be between Full and
Low.
Automatic Transaxle Fluid
(ATF)
•Low fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and transaxle
malfunction.
•Use specified fluid (page 10-4). A
nonspecified fluid could result in
transaxle malfunction and failure.
CAUTION
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.

Fully insert the dipstick. When adding
fluid, inspect with the dipstick to make
sure it doesn’t pass full.

Inspecting Washer Fluid Level•Use the cold scale only as a
reference.
•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.
•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.
NOTE
Inspect the fluid on both sides of the
dipstick in a well lit area for an
accurate reading.
CAUTIONWasher Fluid
Substitute Washer Fluid:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the
windshield, affect your visibility, and
could result in an accident. Use only
windshield washer fluid or plain
water in the reservoir.
Using Washer Fluid Without Anti-
freeze Protection in Cold Weather:
Operating your vehicle in
temperatures below 4 degrees C (40
degrees F) using washer fluid without
anti-freeze protection is dangerous as
it could cause impaired windshield
vision and result in an accident. In
cold weather, always use washer fluid
with anti-freeze protection.
NOTE
State or local regulations may restrict
the use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides
adequate freeze resistance for all
regions and climates in which the
vehicle will be operated.

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.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 engine hood’s secondary
latch keeps the hood from opening when
the primary latch is released.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.

Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.
If the blades are not wiping properly,
clean the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.

Replacing Windshield Wiper
Blades
When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.
1. Raise the wiper arm and turn the blade
assembly to expose the plastic locking
clip.
Slide the assembly downward; then lift
it off the arm.
Wiper Blades
•Hot waxes applied by automatic car
washers have been known to affect
the cleanability of windows.
•To prevent damage to the wiper
blades, don’t use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
•When the wiper lever is in the
AUTO position and the ignition
switch is in the ON position, the
wipers may move automatically in
the following cases:
If the windshield above the rain
sensor is touched.
If the windshield above the rain
sensor is wiped with a cloth.
If the windshield is given a
shock.
If the rain sensor is given a shock
from inside the vehicle.
Be careful not to pinch hands or
fingers as it may cause injury, or
damage the wipers. When washing or
servicing your Mazda, make sure the
wiper lever is in the OFF position.
CAUTION
To prevent damage to the wiper arms
and other components, don’t move the
wipers by hand.
