Recommended Oil
Oil container labels provide important
information.
The quality designation SL
or ILSAC

must be on the label.
Engine oil viscosity, or thickness, has an
effect on fuel economy and cold-weather
operation (starting and oil flow).
Low-viscosity engine oils can provide
improved fuel economy and cold-weather
performance.
But high-temperature weather conditions
require higher-viscosity engine oils for
satisfactory lubrication.When choosing an oil, consider the
temperature range your vehicle will
operate in before the next oil change.
Then select the recommended viscosity
from this chart.
Energy conserving oils are recommended.
A chief contribution they make to fuel
economy is reducing the amount of fuel
necessary to overcome engine friction.

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 5 minutes for the
oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.

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.
Don’t add engine oil over MAX. This
may cause engine damage.

CAUTION
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 any oil splatter from the
exhaust manifold, the exhaust pipe and
the shield. Oil left on these areas will
smoke when the engine is running.

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 FULL or F and
LOW or L marks on the coolant reservoir
when the engine is cool.If it’s at or near LOW or L, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL or F.
Do not overfill.

If new coolant is required frequently,
consult an Authorized Mazda Dealer.
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.
WARNING
2.3-liter engine
Radiator coolant will damage paint.
Rinse it off quickly.

Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
For mixture percentage:To change coolant
1. Remove the cooling system cap. •
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.

CAUTIONRemoving 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.
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 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.

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.
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 yourselfor 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.
WARNING•
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 10-3) 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.

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 10-3). 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.
