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.Brake Fluid
qInspecting 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.

qAdding Brake 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 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.
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
CAUTION
lBrake fluid will damage painted
surfaces. If brake fluid does get on a
painted surface, wipe it off
immediately.
lUsing 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.
Clutch Fluid
qInspecting Clutch Fluid Level
Inspect the level in the clutch fluid
reservoir regularly. It should be kept at
MAX.
qAdding Clutch Fluid
WARNING
Spilled Clutch Fluid:
Spilled clutch 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. Clutch fluid
spilled on a hot engine could cause a
fire. Be careful not to spill clutch fluid
on yourself or on the engine.
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.

NOTE
Low clutch fluid level may signal a
fluid leak. If you find a low fluid level,
have the clutch inspected.
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 10-4).
Inspect the fluid level at each engine oil
change. Add fluid if necessary; it does not
require periodic changing.
Full
Low OK

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.Automatic Transmission
Fluid (ATF)
qInspecting 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).
CAUTION
lLow fluid level causes transmission
slippage. Overfilling can cause
foaming, loss of fluid, and
transmission malfunction.
lUse specified fluid (page 10-4). A
nonspecified fluid could result in
transmission malfunction and failure.
lThe 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.
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.

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.
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.
FULL
LOW
Fluid
cold
scale
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.
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.
NOTE
Use the cold scale as a reference.
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.

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.
Air Filter
CAUTION
Don't drive without an air filter. This
could result in excessive engine wear.
This air filter may be cleaned with
compressed air and reused, or replaced,
depending on its condition. Unless it is
very dirty, simply shake it to remove
foreign particles. Each time you inspect it,
wipe inside the air cleaner housing with a
damp cloth.
qReplacing the Air Filter
NOTE
If the vehicle is operated in very dusty
or sandy areas, replace the filter more
often than recommended intervals.
1. Loosen the bolt and remove the hose.
