Air bag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.

sound to remind you to fasten your
safety belt. Refer to theSeating
and safety restraintschapter.
Charging system:Illuminates when
the battery is not charging properly.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
specificationschapter.
Engine coolant temperature:
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as possible , switch off the engine and let cool. Refer to
Engine coolantin theMaintenance and specificationschapter.

²If steam is coming from the engine compartment:do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch
to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
²If neither coolant nor steam is escaping:open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is low, look for leaks in the radiator
hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an Authorized Mazda dealer.
SeeAdding coolantin theMaintenance and specificationssection. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note:If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
WARNING: The use of tire sealants is not recommended and
may damage your tires.
Temporary spare tire information (if equipped)
Your vehicle may be equipped with a conventional spare tire that may be
different in size (smaller diameter and narrower width) than other tires
on your vehicle. If this is the case, your spare tire is considered
ªtemporaryº and the spare wheel will be labeled as such. Replace this
tire with a tire of the same size, speed rating and load carrying capacity
as the other road tires as soon as possible.

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
4.5É C (40É F), 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.

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.
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
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:
²maximum cooling system efficiency.
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.
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.
