WARNING

Do not perform maintenance work if you lack sufficient knowledge and experience or
the proper tools and equipment to do the work. Have maintenance work done by a
qualified technician:

Performing maintenance work on a vehicle is dangerous if not done properly. You
can be seriously injured while performing some maintenance procedures.

If you must run the engine while working under the hood, make certain that you
remove all jewelry (especially rings, bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing before getting near the engine or cooling
fan which may turn on unexpectedly:

Working under the hood with the engine running is dangerous. It becomes even
more dangerous when you wear jewelry or loose clothing.
Either can become entangled in moving parts and result in injury.

Switch the ignition to off and make sure the fan is not running before attempting to
work near the cooling fan:

Working near the cooling fan when it is running is dangerous. The fan could
continue running indefinitely even if the engine has stopped and the engine
compartment temperature is high. You could be hit by the fan and seriously injured.

Do not leave items in the engine compartment:

After you have finished checking or doing servicing in the engine compartment, do
not forget and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine compartment could cause engine damage or a
fire leading to an unexpected accident.

Engine Coolant

qInspecting Coolant Level

WARNING

Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:

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.

Switch the ignition to off and

make sure the fan is not running before
attempting to work near the cooling
fan:

Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.

Do not remove the cooling

system cap when the engine and
radiator are hot:

When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.

NOTE

Changing the coolant should be done by an
Authorized Mazda Dealer.

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.

If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.

CAUTION

Ø Radiator coolant will damage

paint.
Rinse it off quickly if spilled.

Ø Use only soft (demineralized)

water in the coolant mixture.
Water that contains minerals will
cut down on the coolant's
effectiveness.

Ø Do not add only water. Always

add a proper coolant mixture.

Ø The engine has aluminum parts

and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.

Ø DO NOT USE coolants Containing

Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.

Ø DO NOT MIX alcohol or methanol

with the coolant. This could
damage the cooling system.

Ø Do not use a solution that

contains more than 60%
antifreeze.
This would reduce effectiveness.

NOTE

If the

“FL22” mark is shown on or near the

cooling system cap, it is recommended to use
Mazda Genuine FL22 engine coolant (page
8-4).

If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

Brake/Clutch Fluid

qInspecting Brake/Clutch Fluid Level

WARNING

If the brake/clutch fluid level is low,
have the brakes inspected:

A low brake/clutch fluid level is
dangerous.
A low level could indicate brake
lining wear or a brake system leak
which could cause the brakes to fail
and lead to an accident.

The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
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.

Power Steering Fluid

qInspecting Power Steering Fluid

Level

CAUTION

To avoid damage to the power
steering pump, do not operate the
vehicle for long periods when the
power steering fluid level is low.

Inspect the fluid level in the reservoir at
each engine oil change with the engine off
and cold.

The level must be kept between MIN and
MAX.

Visually examine the lines and hoses for
leaks and damage.

If the fluid decreases significantly or the
fluid level is around MIN or lower than
MIN, consult an Authorized Mazda
Dealer to have the vehicle inspected.

Washer Fluid

qInspecting Washer Fluid Level

WARNING

Use only windshield washer fluid or
plain water in the reservoir:

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.

Using Washer Fluid Without Anti-freeze
Protection in Cold Weather:

Operating your vehicle in
temperatures below 4 degrees C (40
degrees F) using washer fluid without
anti-freeze protection is dangerous
as it could cause impaired windshield
vision and result in an accident. In
cold weather, always use washer
fluid with anti-freeze protection.

NOTE

State or local regulations may restrict the use
of volatile organic compounds (VOCs), which
are commonly used as anti-freeze agents in
washer fluid. A washer fluid with limited VOC
content should be used only if it provides
adequate freeze resistance for all regions and
climates in which the vehicle will be operated.

Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.

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.

Wiper Blades

CAUTION

Ø Hot waxes applied by automatic

car washers have been known to
affect the wiper's ability to clean
windows.

Ø To prevent damage to the wiper

blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.

Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.

If the blades are not wiping properly,
clean the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.

qReplacing Windshield Wiper Blades

When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.

CAUTION

To prevent damage to the wiper arms
and other components, don't try to
sweep the wiper arm by hand.

chemicals known to the State of California to cause cancer and reproductive harm.

Read the following precautions carefully before using the battery or inspecting

to ensure safe and correct handling:

Always wear eye protection when working near the battery:

Working without eye protection is dangerous. Battery fluid contains SULFURIC ACID
which could cause blindness if splashed into your eyes. Also, hydrogen gas produced
during normal battery operation, could ignite and cause the battery to explode.

Wear eye protection and protective gloves to prevent contact with battery

fluid:

Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID which could cause serious injuries if it gets in
eyes, or on the skin or clothing. If this happens, immediately flush your eyes with
water for 15 minutes or wash your skin thoroughly and get medical attention.

Always keep batteries out of the reach of children:

Allowing children to play near batteries is dangerous. Battery fluid could cause
serious injuries if it gets in the eyes or on the skin.

Keep flames and sparks away from open battery cells and do not allow metal

tools to contact the positive (

) or negative ( ) terminal of the battery when

working near a battery. Do not allow the positive (

) terminal to contact the vehicle

body:

Tires

For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.

WARNING

Using Different Tire Types:

Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.

Using Wrong-Sized Tires:

Using any other tire size than what is
specified for your Mazda (page 10-7)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.

qTire Inflation Pressure

WARNING

Always inflate the tires to the correct
pressure:

Overinflation or underinflation of
tires is dangerous. Adverse handling
or unexpected tire failure could result
in a serious accident.
Refer to Tires on page 10-7.

Use only a Mazda-genuine tire valve
cap:

Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tire valve cap that is not a Mazda-
genuine part.

The Tire Pressure Monitoring System

does not alleviate the need to check the
tire condition every day, including
whether the tires all look inflated properly.
Inspect all tire pressure monthly when the
tires are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tire wear.
When checking the tire pressures, use of a
digital tire pressure gauge is
recommended.

Refer to the specification charts (page
10-7).

NOTE

Always check tire pressure when tires are
cold.

Warm tires normally exceed recommended
pressures. Don't release air from warm tires
to adjust the pressure.

Underinflation can cause reduced fuel
economy, uneven and accelerated tire wear,
and poor sealing of the tire bead, which
will deform the wheel and cause separation
of tire from rim.

Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.

qTire Rotation

WARNING

Rotate tires periodically:

Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires according to
the scheduled maintenance charts.
Refer to Scheduled Maintenance on
page 8-4.

During rotation, inspect them for correct
balance.

NOTE

Because your vehicle is not equipped with a
spare tire, you cannot do a tire rotation safely
with the jack that comes with your vehicle.
Have an Authorized Mazda Dealer perform
tire rotation.

Do not include (TEMPORARY USE ONLY)
spare tire in rotation.

Forward

Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tire pressure

Improper wheel alignment

Out-of-balance wheel

Severe braking
