Owner Maintenance Precautions
Improper or incomplete service may result in problems. This section gives instructions only
for items that are easy to perform.
As explained in the Introduction (page 8-2), several procedures can be done only by a
qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage.
For details, read the separate Mazda Warranty statement provided with the vehicle. If
you're unsure about any servicing or maintenance procedure, have it done by an
Authorized Mazda Dealer.
There are strict environmental laws regarding the disposal of waste oil and fluids. Please
dispose of your waste properly and with due regard to the environment.
We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized
Mazda Dealer.
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.

Brake/Clutch Fluid
qInspecting 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.
qAdding Brake/Clutch Fluid
WARNING
Be careful not to spill brake fluid on
yourself or on the engine:
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.
If the brake/clutch fluid level is low,
have the brakes and clutch inspected: 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 the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
CAUTION
Ø Brake and clutch fluid will
damage painted surfaces. If brake
or clutch fluid does get on a
painted surface, wash it off with
water immediately.
Ø Using 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
qInspecting 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).
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.
Washer Fluid
q Inspecting 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.

Battery
WARNING
Wash hands after handling the battery and related accessories:Battery posts, terminals and related accessories contain lead and lead compounds,
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:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries. Keep all flames including
cigarettes and sparks away from open battery cells.

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 Systemí
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
lAlways check tire pressure when tires are
cold.
lWarm tires normally exceed recommended
pressures. Don't release air from warm tires
to adjust the pressure.
lUnderinflation 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.
lOverinflation 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 8-3.
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:
lIncorrect tire pressurelImproper wheel alignmentlOut-of-balance wheellSevere braking

After rotation, inflate all tire pressures to
specification (page 10-7) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to
rear, not from side to side. Tire
performance will be reduced if
rotated from side to side.
CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Replace all four tires at the same time: Replacing just one tire is dangerous.
It could cause poor handling and
poor braking resulting in loss of
vehicle control. Mazda strongly
recommends that you replace all four
tires at the same time.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.
NOTE
(With Tire Pressure Monitoring System)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-34.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-35.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
