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.

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.
CAUTION
Don't add engine oil over MAX. This
may cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
qChanging 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.
CAUTION
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.
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 MAX mark on the dipstick. 6. Securely reinstall the oil-filler cap.

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 MAX
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 EngineInspection:
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.

qAdding Brake/Clutch 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/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.
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
CAUTION
lBrake and clutch fluid will damage
painted surfaces. If brake or clutch
fluid does get on a painted surface,
wipe it off immediately.
lUsing nonspecified brake and clutch
fluids (page 10-4) 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.
Power Steering Fluid
q Inspecting 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).
2.3-liter engine
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.
3.0-liter engine
Inspect the fluid level at each engine oil
change. Add fluid if necessary; it does not
require periodic changing.
LowOK
High Loosen
Tighten
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 Transaxle Fluid
(ATF)
q 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.
CAUTION
lLow fluid level causes transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and transaxle
malfunction.
lUse specified fluid (page 10-4). A
nonspecified fluid could result in
transaxle malfunction and failure.
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.

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.
q Replacing the Air Filter
NOTE
If the vehicle is operated in very dusty
or sandy areas, replace the filter more
often than recommended intervals.
1. Unfasten the clamps.
