qParking in Direct Sunlight

Operating Tips

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.

qOperating the Climate Control

System

Operate the climate control system with

the engine running.

qNot Using for a Long Period

Run the air conditioner about 10 minutes

at least once a month to keep internal

parts lubricated.

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.

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

qClearing the Air Inlet

efficient. Consult an Authorized Mazda

Dealer for refrigerant inspection.

Clear all obstructions like leaves, snow

and ice from the hood and the air inlet in

the cowl grille to improve the system

efficiency.

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.

qReplacement of the Cabin Air

Filter

To help defog the windows, operate the

air conditioner to dehumidify the air.

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.

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.
