Climate Control System

Operating Tips

Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
switch 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 ef ciency.
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 traf c 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.
5–2
Run the air conditioner 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
ef cient.
The refrigerant speci cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before re lling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
For details, consult an Authorized
Mazda Dealer.
