Engine Oil
qRecommended Oil
Use SAE 5W-20 engine oil.
Oil container labels provide important
information.
A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine
friction.
U.S.A. and CANADA
(ILSAC)
Only use oils “Certified For Gasoline
Engines ”by the American Petroleum
Institute (API). An oil with this trademark
symbol conforms to the current engine
and emission system protection standards
and fuel economy requirements of the
International Lubricant Standardization
and Approval Committee (ILSAC),
comprised of U.S. and Japanese
automobile manufacturers.

Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and reinsert it fully.
Full
Low OK
5. Pull it out again and examine the level.It's OK between L and F.
But if it's near or below L, add enough
oil to bring the level to F.
CAUTION
Don't add engine oil over F. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
The distance between L and F on the
dipstick represents the following:
Oil capacity
L (US qt, Imp qt) 0.8 (0.85, 0.70)
q 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.
WARNING
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.

Changing engine oil
WARNING
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.
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 drain plug washer after the oil has thoroughly drained.
4. Reinstall the plug tightly.
5. Fill the engine with new oil to the F mark on the dipstick.
6. Securely reinstall the oil-filler cap.

7. Start the engine and inspect around thedrain plug for leaks.
8. Turn it off and wait 5 minutes for the oil to return to the oil pan. Check the oil level and fill to the F mark
if necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
NOTE
lThe indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
lUse only specified engine oil (page
10-4).
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Engine Coolant
qInspecting Coolant Level
WARNING
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. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS
HOT.
Cooling Fan and Engine
Inspection:
Inspecting the engine with the ignition
switch in the ON position is
dangerous. The cooling fan could turn
on unexpectedly even when the engine
isn't running. You could be seriously
injured by the fan. Turn the ignition
switch off and remove the key from the
ignition switch when you inspect the
engine.
Cooling System Cap:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove the cooling
system cap when the engine and
radiator are hot. 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 FULL and LOW
marks on the coolant reservoir when the
engine is cool.
If it's at or near LOW, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

qChanging Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
CAUTION
lUse only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant's effectiveness.
lDon't add only water. Always add a
proper coolant mixture.
lThe engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
lDO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
lDO NOT MIX alcohol or methanol
with the coolant. This could damage
the cooling system.
lDon't use a solution that contains
more than 60% antifreeze.
This would reduce effectiveness.

WARNING
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.
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 andtighten 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
q Inspecting 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.
