Operating Tips
▼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 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.
(With A/C switch)
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
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.
