To change coolant
1. 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 to the first stop.
Step back while the pressure escapes.
When you ’re sure all the pressure is
gone, press down on the cap — still
using a cloth — turn the cap, and
remove it.

Inspecting Brake Fluid Level
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 linings. If it
is excessively low, have the brake system
inspected by an Authorized Mazda
Dealer.

Adding Brake Fluid
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
Brake 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 Fluid Levels:
Low brake 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 inspected.
• Brake fluid will damage painted
surfaces. If brake fluid does get on
a painted surface, wipe it off
immediately.
• Using nonspecified brake fluids
(page 10-4) will damage the system.
Mixing different fluids will also
damage it.
If the brake system frequently
requires new fluid, consult an
Authorized Mazda Dealer.

Inspecting Power Steering Fluid
Level
Inspect the fluid level at each engine oil
change. Add fluid if necessary; it does not
require periodic changing.
The level must be kept between the H and
L marks.
Visually examine the lines and hoses for
leaks and damage.
1. Park on a level surface, well off the
right-of-way, and set the parking brake
firmly.
2. Turn off the engine and allow it to cool. 3. Remove the filler cap and attached
dipstick.
4. Wipe them clean and put them back.
5. Remove again and inspect the level.
6. It must be between H and L. Add fluid if necessary.
Don ’t overfill.
If new fluid is required frequently, consult
an Authorized Mazda Dealer.
Power 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
Transmission Fluid Level
The automatic transmission fluid level
should be inspected regularly. Measure it
as described below.
The volume of fluid changes with the
temperature. For that reason, it is best to
examine the level after having driven the
vehicle for 15 minutes. If necessary,
however, it can also be inspected without
driving when the outside temperature is
above 20
°C (70 °F).
1. Park on a level surface and set the parking brake firmly.
2. Idle the engine. 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.
5. Put the dipstick back into the filler tube and make sure it is fully seated.
6. Pull the dipstick out and read the fluid level.
The proper fluid level is marked on the
dipstick as follows.
Fluid hot scale
When checking the fluid level at normal
operating temperature, the fluid level
should be within the FULL and LOW
marks on the dipstick.
Automatic Transmission
Fluid (ATF)
• Low fluid level causes transmission
slippage. Overfilling can cause
foaming, loss of fluid, and
transmission malfunction.
• Use specified fluid (page 10-4). A
nonspecified fluid could result in
transmission malfunction and
failure.
• The vehicle should not be driven if
the fluid level is below the bottom
of the dipstick and the outside
temperature is above 20
°C (70° F),
or if evident automatic transmission
fluid leaks are found.
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.

Fluid cold scale
When the vehicle has not been driven but
the engine is idling, and the outside
temperature is above 20°C (70 °F), the
fluid level should be close to, but not
above, the bottom notch on the dipstick.
Fully insert the dipstick. When adding
fluid, inspect with the dipstick to make
sure it doesn ’t pass full.

Inspecting Washer Fluid Level
NOTE
Use the cold scale as a reference.
NOTE
Inspect the fluid on both sides of the
dipstick in a well lit area for an
accurate reading.
Washer 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.

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.
Compress the clip and 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.
CAUTION
To prevent damage to the wiper arms
and other components, don ’t move the
