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.
NOTE:
²The vehicle may need to be driven to relearn the idle and fuel trim
strategy.
²If 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
Maintenance and Specifications

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.
²Always 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
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the service maintenance section. The coolant
concentration should be maintained at 50/50 coolant and water, which
equates to a freeze point of -36É C (-34É F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014±R1060). The level of coolant
should be maintained at the ªcold fullº of ªcold fill rangeº level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in theAdding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50±50 mixture of coolant and water provides the following:
²freeze protection down to -36É C (-34É F).
²boiling protection up to 129É C (265É F).
²protection against rust and other forms of corrosion.
²an accurate temperature readout from the engine coolant
gauge.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
²The engine coolant should be at the ªcold fill levelº or within the ªcold
fill rangeº as listed on the engine coolant reservoir (depending upon
application).
²Refer to the Scheduled Maintenance section for service interval
schedules.
²Be sure to read and understandPrecautions when servicing your
vehiclein 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 toAdding
engine coolantin 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
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.
WARNING: Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant
on hot engine parts.
WARNING: Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
Maintenance and Specifications
220

The cooling system in your vehicle is filled with either green-colored or
yellow-colored Mazda Premium Engine Coolant meeting Mazda
Specifications. To determine your vehicle's coolant type (color), check
your coolant reservoir.
To maintain the integrity of the coolant and the cooling system
and maintain the warranty on the cooling system:
²Add Mazda Premium Engine Coolant or the type of coolant
originally equipped in your vehicle.If you are unsure which type
of coolant your vehicle requires, check your coolant reservoir or
contact your local dealer.
²Do not add/mix an orange-colored, extended life coolant such
as Mazda Speciality Orange Engine Coolant, meeting Mazda
specifications with the factory-filled coolant.Mixing Mazda
Speciality Orange Engine Coolant or any orange-colored extended life
product with your factory filled coolant can result in degraded
corrosion protection.
²A 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.
²Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
²Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
²Do not mix with recycled coolant unless from a
Mazda-approved recycling process (seeUse of Recycled Engine
Coolantsection.
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 ªcold fullº 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.
Maintenance and Specifications
221

WARNING: To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief
cap. The cooling system is under pressure; steam and hot liquid
can come out forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic
bottle). Slowly turn cap counterclockwise (left) 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 ªcold fill rangeº or the ªcold fullº 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, run the engine for a few minutes to
mix the coolant. Check the coolant concentration. Make sure the engine
is off and cool before removing the coolant pressure relief cap (see
preceding steps on cap removal). Check the concentration per the
Checking Engine Coolantsection. If the concentration is not 50/50
(protection to ±34ÉF/±36ÉC), 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 liter (1.0 quart) of engine coolant per
month, have your 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 recommend coolants. Use of a recycled engine coolant
which does not meet the Mazda recommended coolant, 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
toRefill capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this chapter.
Severe climates
If you drive in extremely cold climates (less than ±36É C [±34É F]):
²It may be necessary to increase the coolant concentration
above 50%.
²NEVER increase the coolant concentration above 60%.
²Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
²Refer 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:
²It is still necessary to maintain the coolant concentration
above 40%.
²NEVER decrease the coolant concentration below 40%.
²Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
²Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
Maintenance and Specifications
223

²Refer 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 pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision,
which may result in possible personal injury.
