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
ON position when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as 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.
