Interior Comfort Climate Control System 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. 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. 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. 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. 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. 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. 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. 6-2
