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.
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 serious
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 conditioner
maintenance.
For details, consult an Authorized
Mazda Dealer.
