Operating Tips
•Operate the climate control system with
the engine running.
•To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
•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.
•Use the climate control system to defog
the windows and dehumidify the air.
•The recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
•Use the outside air position for
ventilation or windshield defrosting.
•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.
•Run the air cond itioner about 10
minutes at least once a month to keep
internal parts lubricated.
•Have the air conditioner checked before
the weather gets hot . Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If the
wrong type of refrigerant is used, it
could result in a ser ious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.

5. After cooling begins, adjust the fancontrol dial and temperature control
dial as needed to maintain maximum
comfort.
CAUTION
If the air conditioner is used while driving
up long hills or in heavy traffic, monitor the
high engine coolant temperature warning
light to see if it is illuminated or flashing
(page 4-24).
The air conditioner may cause engine
overheating. If the warning light is
illuminated or flashing, turn the air
conditioner off (page 7-22).
NOTE
•(Type A)
When maximum cooling is desired, set
the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then turn the fan control dial
fully clockwise.
•(Type B)
When maximum cooling is desired, set
the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then set the fan control dial to
position 4.
•If warmer air is desired at floor level,
set the mode selector dial at the
position and adjust the temperature
control dial to maintain maximum
comfort.
•The air to the floor is warmer than air
to the face (except when the temperature
control dial is set at the extreme hot or
cold position).

Use this mode for ventilation or
windshield defrosting.
WA R N I N G
Do not use the position in cold or rainy

▼ Operation of Automatic Air
Conditioner
1. Set the mode selector dial to the
AUTO position.
2. Set the air intake s elector to the outside
air position (indicato r light turned off).
NOTE
If the recirculated air position is used
for long periods in cold weather or
high humidity, the wi ndshield may fog
up more easily.
3. Set the fan control dial to the AUTO
position.
4. Press the A/C switch to operate the air
conditioner (turn i ndicator light on).
5. Set the temperature control dial to the desired position.
6. To turn off the system, set the fan
control dial to the 0 position.
NOTE
•Setting the temperature to maximum hot
or cold will not provide the desired
temperature at a faster rate.
•When selecting heat, the system will
restrict airflow until it has warmed to
prevent cold air from blowing out of the
vents.
▼Windshield Defrosting and
Defogging
Set the mode selec
tor dial to the
position and turn the f an control dial to the
desired speed.
In this position, the outside air position is
automatically selected, and when the fan
control dial is ON, the air conditioner
automatically turns on. The air conditioner
will directly dehumidify the air to the front
windshield and side windows (page 5-6).
Airflow amount will be increased.
WA R N I N G
Set the temperature control to the hot or
warm position when defogging (
position):
Using the
position with the temperature
control set to the cold position is
dangerous as it will cause the outside of the
windshield to fog up. Your vision will be
hampered, which could lead to a serious
accident.
NOTE
Use the temperature control dial to
increase the air flow temperature and
defog the windshield more quickly.
