WINDSHIELD WASHER FLUID
Windshield washer fluid
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets Mazda specification . Refer to
Lubricant specificationsin this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
WARNING: If you operate your vehicle in temperatures below
40°F (4.5°C), use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze protection in cold
weather could result in impaired windshield vision and increase
the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.

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.

A50/50 mixtureof 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.

•3.0L & 4.0L engines
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 theService Maintenance Sectionfor service interval
schedules.
•Be 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
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 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 the engine is cool, add a50/50 mixtureof engine coolant and
distilled water to the engine coolant reservoir, until the coolant is at
the“FULL COLD”level or within the“COLD FILL RANGE”as listed in
the engine coolant reservoir (depending upon application).
•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.
Plain water may be added in an emergency, but youmustreplace it with
a 50/50 mixture of engine coolant and distilled water as soon as possible.
Check the coolant level in the reservoir before you drive your vehicle the
next few times (with the engine cool). If necessary, add a50/50

mixtureof engine coolant and distilled water to the engine coolant
reservoir until the coolant level is at the“FULL COLD”level or within
the“COLD FILL RANGE”as listed on the reservoir (depending upon
application).
Have your dealer check the engine cooling system for leaks if you have
to add more than 1.0 quart (1.0 liter) of engine coolant per month.
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.
If you must remove the coolant cap, follow these steps to avoid 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.
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
toRefill capacitiesin this section.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this section.
