Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with
the ignition switch in the ACC position
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions like leaves, snow
and ice from the hood and the air inlet in
the cowl grille to improve the system
efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
NOTE
The air conditioner may be used along
with the heater to dehumidify the air.
qOutside/Recirculated Air Position
Use the outside air position in normal
conditions. The recirculated air position
should be used only when driving on
dusty roads or for quick cooling of the
interior.
qParking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air Filter
If your vehicle is equipped with an air
filter for the air conditioner, it is necessary
to change the filter periodically as
indicated in scheduled maintenance (page
8-3). Consult an Authorized Mazda
Dealer for replacement of the cabin air
filter.

lIf the cassette tape is loose, it may
produce poor sound or performance
during playback. Use a pencil or
something similar to remove any slack.
lOnly cassette tapes that play no longer
than 90 minutes should be used.
Cassette tape exceeding 90 minutes are
thin and may easily break.
lDo not leave a cassette tape in the tape
player slot when not in use. Remove it
completely to permit the slot door to
close and to protect the mechanism
from dust.
lStore cassette tapes away from extreme
heat, magnetic fields, and direct
sunlight. Protect the exposed cassette
tape from dirt and damage. Store
cassette tapes in their original cases or
other protective cases.
qOperating Tips for CD Player/In-
Dash CD Changer
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in the
CD player/In-dash CD changer may
become clouded with condensation. At
this time, the CD will eject immediately
when placed in the unit. A clouded CD
can be corrected simply by wiping it with
a soft cloth. Clouded optical components
will clear naturally in about an hour. Wait
for normal operation to return before
attempting to use the unit.
Handling the CD player/In-dash CD
changer
The following precautions should be
observed.
lDo not spill any liquid on the audio
system.
lDo not insert any objects, other than
CDs, into the slot.

Engine Coolant
qInspecting Coolant Level
WARNING
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS
HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Turn off the ignition switch and
make sure the fan is not running
before attempting to work near the
cooling fan:
Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and the
engine compartment temperature is
high. You could be hit by the fan and
seriously injured.
Do not remove the cooling
system cap when the engine and
radiator are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
NOTE
Changing the coolant should be done
by an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the MAX or F and
MIN or L marks on the coolant reservoir
when the engine is cool.
