Before Driving Your Mazda
Form No. 8R09-EA-02G
Before Starting the Engine
•Be sure the windows, outside mirrors,
and outside lights are clean.
• Inspect inflation pressures and
condition of tires.
• Look under the vehicle for any sign of
a leak.
• If you plan to back up, make sure
nothing will be in your way. •
Are all doors closed and locked?
• Is the seat adjusted properly?
• Are the inside and outside mirrors
adjusted?
• Is everyone
’s seat belt fastened?
• Do all the lights work?
• Check all gauges.
• Check all warning lights when the
ignition switch is turned to the ON
position.
• Release the parking brake and make
sure the parking brake warning light
goes off.
Always be thoroughly familiar with your
Mazda.
Before Getting In
NOTE
Engine oil, engine coolant, brake/
clutch fluid, washer fluid, and other
fluid levels should be inspected daily,
weekly, or at refueling, depending on
the fluid. See Maintenance, Section 8.

In Case of an Emergency
Form No. 8R09-EA-02G
Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transmission in park (P), a manual
transmission in neutral.
Apply the parking brake.
3. Turn off the air conditioner. 4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don ’t go near the front of the vehicle.
Stop the engine. Then turn the ignition
switch to the ON position without
starting the engine.
The radiator cooling fans will start to
cool the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools. If this doesn ’t lower the
temperature, stop the engine and let it
cool.
5. Visually inspect the alternator/water pump drive belt for looseness and
breakage and all cooling hose
connections for leaks. If the belt is
broken or coolant is leaking, call an
Authorized Mazda Dealer for
assistance.
6. If the drive belt is OK, the engine is cool, and no coolant leaks are obvious,
inspect the coolant level. Carefully add
coolant as required (page 8-15).
Overheating
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.

Owner Maintenance
The owner or a qualified service technician should make these vehicle inspections at the
indicated intervals to ensure safe and dependable operation.
Bring any problem to the attention of an Authorized Mazda Dealer or qualified service
technician as soon as possible.

When Refueling
• Brake and clutch fluid level (page 8-17)
• Engine coolant level (page 8-15)
• Engine oil level (page 8-13)
• Washer fluid level (page 8-22)


At Least Monthly
• Tire inflation pressures (page 8-28)


At Least Twice a Year (For Example, Every Spring and Fall)
• Automatic transmission fluid level (page 8-20)
• Power steering fluid level (page 8-19)
You can do the following scheduled maintenance items if you have some mechanical
ability and a few basic tools and if you closely follow the directions in this manual.
• Air filter (page 8-23)
• Engine coolant (page 8-15)
• Engine oil (page 8-14)

Check the oil level and fill to the F 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 FULL and LOW
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 LOW, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.

Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3). For mixture percentage:
To change coolant
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.

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 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 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.
