Interior Comfort  
Climate Control System  
qNot Using for a Long Period  
Operating Tips  
Run the air conditioner about 10 minutes  
at least once a month to keep internal  
parts lubricated.  
qOperating the Climate Control  
System  
Operate the climate control system with  
the engine running.  
qCheck the Refrigerant before the  
Weather Gets Hot  
NOTE  
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.  
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  
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.  
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.  
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.

When using the air conditioner, mist may come out from the vents. This is not a sign of trouble but a  
result of humid air being suddenly cooled.
