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 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.
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.

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
WARNING
Cooling Fan and EngineInspection:
Inspecting the engine with the ignition
switch in the ON position is
dangerous. The cooling fan could turn
on unexpectedly even when the engine
isn't running. You could be seriously
injured by the fan. Turn the ignition
switch off and remove the key from the
ignition switch when you inspect the
engine.
Cooling System Caps:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury. Don't remove either cooling
system cap when the engine and
radiator are hot.
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.If the temperature gauge indicates
overheating:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
Apply the parking brake.
3. Turn off the air conditioner.
4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the enginecompartment:
Don't go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.
If neither coolant nor steam isescaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
5. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
6. When cool, check the coolant level.
If it's low, look for coolant leaks from
the radiator and hoses.
