BATTERY

Your vehicle is equipped with a
Mazda maintenance-free battery
which normally does not require
additional water during its life of
service.

If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.

For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.

If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.

Note: Electrical or electronic accessories or components added to
the vehicle by the dealer or the owner may adversely affect
battery performance and durability.

It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.

WARNING:

Batteries normally produce explosive gases which

can cause personal injury. Therefore, do not allow flames, sparks

or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.

WARNING:

When lifting a plastic-cased battery, excessive

pressure on the end walls could cause acid to flow through the

vent caps, resulting in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.

WARNING:

Keep batteries out of reach of children. Batteries

contain sulfuric acid. Avoid contact with skin, eyes or clothing.

Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.

WARNING:

Battery posts, terminals and related accessories

contain lead and lead compounds. Wash hands after handling.

Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:

1. With the vehicle at a complete stop, set the parking brake.

2. Put the gearshift in P (Park) (automatic transmission) or the neutral

position (manual transmission), turn off all accessories and start the
engine.

3. Run the engine until it reaches normal operating temperature.

4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.

• The vehicle may need to be driven 10 miles (16 km) or more to

relearn the idle and fuel trim strategy.

• If you do not allow the engine to relearn its idle trim, the idle

quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.

When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.

If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
• Always dispose of automotive

batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.

ENGINE COOLANT

Checking engine coolant

Your engine’s cooling system has been factory-filled with a 50/50 mixture
of distilled water and Mazda engine coolant, or an equivalent premium
engine coolant that meets Mazda specification.

A 50/50 mixture of distilled water and Mazda engine coolant provides:
• maximum cooling system efficiency.
• freeze protection down to -34°F (-36°C).
• boiling protection up to 265°F (129°C).
• protection against rust and other forms of corrosion.
• an accurate temperature readout from the engine coolant

gauge.

The engine coolant must be maintained at the correct fluid level
and concentration to work properly. If the engine coolant fluid
level and concentration is not maintained correctly, damage to
the engine and cooling system may result.

When the engine is cold, check the level of the engine coolant in the
reservoir.
• The engine coolant should be at the “cold fill level” or within the “cold

fill range” as listed on the engine coolant reservoir (depending upon
application).

• Confirm the color and type of engine coolant before adding, to avoid

mixing incompatible products.

• Refer to scheduled maintenance for service interval schedules.
• Be sure to read and understand Precautions when servicing your

vehicle in this chapter.

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer to Adding
engine coolant in this chapter.

WARNING:

Automotive fluids are not interchangeable; do not

use engine coolant, antifreeze or windshield washer fluid outside

of its specified function and vehicle location.

Adding engine coolant

Use only Mazda engine coolant or a premium engine coolant that
meets a Mazda specification.
• DO NOT USE Extended Life Engine Coolant (orange in color).
• DO NOT USE a DEX-COOL威 engine coolant or an equivalent

engine coolant.

• DO NOT USE alcohol or methanol antifreeze or any engine

coolants mixed with alcohol or methanol antifreeze.

• DO NOT USE supplemental coolant additives in your vehicle.

These additives may harm your engine’s cooling system.

• DO NOT MIX different colors or types of coolant in your

vehicle. Make sure the correct coolant is used.

• DO NOT MIX recycled coolant and conventional coolant

together in your vehicle. Mixing of engine coolants may harm
your engine’s cooling system.

• The use of an improper coolant may harm engine and cooling

system components and may void the warranty of your vehicle’s

WARNING:

Do not put engine coolant in the windshield washer

fluid reservoir. If engine coolant is sprayed onto the windshield,

it could make it difficult to see through the windshield.

When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir, when the
engine is cool,

until the appropriate fill level is obtained.

• NEVER increase the coolant concentration above 60%.
• NEVER decrease the coolant concentration below 40%.
• Engine coolant concentrations above 60% or below 40% will

decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.

A large amount of water without engine coolant may be added, in case of
emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.

For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the FULL COLD level. For all other vehicles, which have a
coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.

Note:

The 4.0L V6 engine uses the overflow system, and the 2.3L I4

engine uses the degas system.

WARNING:

To avoid scalding hot steam or coolant from being

released from the engine cooling system, never remove the

reservoir cap while the engine is running or hot. Failure to follow this
warning may result in possible severe personal injury and damage to
the engine’s cooling system.

Add the proper mixture of coolant and water to the cooling system by
following these steps:

1. Before you remove the cap, turn the engine off and let it cool.

2. When the engine is cool, wrap a thick cloth around the cap. Slowly

turn cap counterclockwise until pressure begins to release.

3. Step back while the pressure releases.

4. When you are sure that all the pressure has been released, use the

cloth to turn it counterclockwise and remove the cap.

5. Fill the coolant reservoir slowly with the proper coolant mixture (see

above), to within the COLD FILL RANGE or the FULL COLD level
on the reservoir. If you removed the radiator cap in an overflow
system, fill the radiator until the coolant is visible and radiator is
almost full.

6. Replace the cap. Turn until tightly installed. Cap must be tightly

installed to prevent coolant loss.

After any coolant has been added, check the coolant concentration, refer
to Checking engine coolant. If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.

Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.

If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.

Recycled engine coolant

Not all coolant recycling processes produce coolant which meets Mazda
specification. Use of a recycled engine coolant which does not meet
Mazda specifications may harm engine and cooling system components.

Always dispose of used automotive fluids in a responsible manner.

Follow your community’s regulations and standards for recycling and
disposing of automotive fluids.

Coolant refill capacity

To find out how much fluid your vehicle’s cooling system can hold, refer
to Maintenance product specifications and capacities in this chapter.

Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.

Severe climates

If you drive in extremely cold climates (less than –34°F [–36°C]):
• It may be necessary to increase the coolant concentration

above 50%.

• NEVER increase the coolant concentration above 60%.
• Increased engine coolant concentrations above 60% will

decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.

• Refer to the chart on the coolant container to ensure the

coolant concentration in your vehicle will provide adequate
freeze protection at the temperatures in which you drive in the
winter months.

If you drive in extremely hot climates:
• It is still necessary to maintain the coolant concentration

above 40%.

• NEVER decrease the coolant concentration below 40%.
• Decreased engine coolant concentrations below 40% will

decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.

• Decreased engine coolant concentrations below 40% will

decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.

• Refer to the chart on the coolant container to ensure the

coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.

WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS

Important safety precautions

WARNING:

Do not overfill the fuel tank. The pressure in an

overfilled tank may cause leakage and lead to fuel spray and fire.

WARNING:

The fuel system may be under pressure. If the fuel

filler cap is venting vapor or if you hear a hissing sound, wait

until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.

WARNING:

If you do not use the proper fuel filler cap,

excessive vacuum in the fuel tank may damage the fuel system

or cause the fuel cap to disengage in a collision, which may result in
serious personal injury.

WARNING:

Automotive fuels can cause serious injury or death

if misused or mishandled.

WARNING:

Gasoline may contain benzene, which is a

cancer-causing agent.

Observe the following guidelines when handling automotive fuel:
• Extinguish all smoking materials

and any open flames before
fueling your vehicle.

• Always turn off the vehicle before

fueling.

• Automotive fuels can be harmful

or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.

• Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind

can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.

Maintenance and Specifications

262

• Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,

remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.

• Fuels can also be harmful if absorbed through the skin. If fuel is

splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.

• Be particularly careful if you are taking “Antabuse” or other forms of

disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.

WARNING:

When refueling always shut the engine off and

never allow sparks or open flames near the filler neck. Never

smoke while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.

WARNING:

The flow of fuel through a fuel pump nozzle can

produce static electricity, which can cause a fire if fuel is

pumped into an ungrounded fuel container.

Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
• Place approved fuel container on

the ground.

• DO NOT fill a fuel container while

it is in the vehicle (including the
cargo area/pickup bed).

• Keep the fuel pump nozzle in contact with the fuel container while

filling.

• DO NOT use a device that would hold the fuel pump handle in the fill

position.

When fueling your vehicle:

1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/4 of a turn to remove

it.

3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the

filler pipe.

5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.

If the check fuel cap light

comes on, the fuel filler cap may not be

properly installed. The light can come on after several driving events
after you’ve refueled your vehicle.
At the next opportunity, safely pull off of the road, remove the fuel filler
cap, align the cap properly and reinstall it. The check fuel cap
light

may not reset immediately; it may take several driving cycles for

the check fuel cap light

to turn off. A driving cycle consists of an

engine start-up (after four or more hours with the engine off) followed
by city and highway driving.

Continuing to drive with the check fuel cap light

on may cause the

service engine soon

light to turn on as well.

If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The warranty may be void
for any damage to the fuel tank or fuel system if the correct
genuine Mazda or other certified fuel filler cap is not used.

WARNING:

The fuel system may be under pressure. If the fuel

filler cap is venting vapor or if you hear a hissing sound, wait

until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.

WARNING:

If you do not use the proper fuel filler cap,

excessive vacuum in the fuel tank may damage the fuel system

or cause the fuel cap to disengage in a collision, which may result in
personal injury.

Choosing the right fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded
fuel or any other fuel. The use of leaded fuel is prohibited by law and
could damage your vehicle.

Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.

Note:

Use of any fuel other than those recommended may cause

powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.

Cleaner air

Mazda endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in the Choosing the right
fuel section.

Octane recommendations

Your vehicle is designed to use
“Regular” unleaded gasoline with a
pump (R+M)/2 octane rating of 87.
Some stations offer fuels posted as
“Regular” with an octane rating
below 87, particularly in high altitude areas. Fuels with octane levels
below 87 are not recommended.

Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.

Fuel quality

If you are experiencing starting, rough idle or hesitation driveability
problems, try a different brand of unleaded gasoline. If the problems
persist, see your authorized dealer.

Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.

Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.
