5. Pull it out again and examine the level.
It’s OK between MIN and MAX.
But if it’s near or below MIN, add
enough oil to bring the level to MAX.
6. Make sure the O-ring is positioned
properly before reinserting the
dipstick.

Changing Engine Oil and Filter
Change engine oil and filter according to
Scheduled Maintenance (page 8-3).
Please act responsibly—protect the
environment and take used oil to a
recycling facility. Ask your dealer or a
service station for information.Changing engine oil
1. Warm up the engine for a few minutes
and turn it off. Remove the oil-filler
cap.
2. Remove the drain plug and drain the oil
into a suitable container.
3. Replace the plug tightly after the oil
has thoroughly drained.
4. Fill the engine with new oil to the
MAX mark on the dipstick.
5. Securely replace the oil-filler cap.
6. Start the engine and inspect around the
drain plug for leaks.
7. Turn it off and wait 5 minutes for the
oil to return to the oil pan. Don’t add engine oil over MAX. This
may cause engine damage.
Handling Used Engine Oil:
Continuous contact with used engine
oil is dangerous. It could cause skin
cancer. Always wash with soap and
water immediately after changing oil
and filter.
Remove oil splatter from the exhaust
manifold, the exhaust pipe and the
shield. Oil left on these areas will
smoke when the engine is running.
CAUTION
WARNING
CAUTION
Checking or Changing Engine Oil:
Hot engine oil is dangerous. If the
engine has been running, the engine
oil becomes very hot. You could be
seriously burned. Don’t check or
change the engine oil when the
engine is hot.

mark if necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year—at the beginning of the
winter season—and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks
on the coolant reservoir when the engine
is cool.
NOTE
•The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
•Use only specified engine oil (page
10-4).
Engine Coolant
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Don’t
inspect the coolant system or add
coolant when the engine is hot.

If it’s at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.

Changing Coolant (Without Rear
Heater)
Change coolant according to Scheduled
Maintenance (page 8-3).For mixture percentage:
To change coolant
1. Remove the cooling system cap. Radiator coolant will damage paint.
Rinse it off quickly.
•Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant’s effectiveness.
•Don’t add only water. Always add a
proper coolant mixture.
•The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
•DO NOT USE alcohol or methanol
antifreeze. DO NOT MIX alcohol
or methanol with the coolant. This
could damage the cooling system.
•Don’t use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

Removing the Cooling System Cap:
Removing the cooling system cap or
drain plug 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
or drain plug. Wrap a thick cloth
around it 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.

2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
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 and
water as necessary to provide freezing
and corrosion protection.
5. In extremely cold climates, add the
amount recommended in the coolant
manufacturer’s instructions.
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.

Changing Coolant (With Rear
Heater)
Have an Authorized Mazda Dealer change
the coolant according to the Scheduled
Maintenance (page 8-3).

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.

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.
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.
WARNING
CAUTION
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 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
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
The top of the float should be between
FULL and LOW.
Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing. •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 both sides of the dipstick for
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.

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.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.

Replacing the Air Filter
1. Remove the bolt and unfasten the
clamps on the air cleaner housing.
