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 lever in P (Park), 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 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 Genuine Engine Coolant, or an equivalent
premium engine coolant that meets Mazda specification.
A 50/50 mixture of distilled water and Mazda Genuine 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 Genuine 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 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
engine cooling system. If you are unsure which type of coolant
your vehicle requires, contact your local authorized dealer.

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 3.0L and 4.0L V6 engines use the overflow system, and the
2.3L I4 engines use 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 damage to the engine’s cooling
system and possible severe personal injury.
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.
