Operating Tips
 












 Operate the air-conditioning 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.
 


(With i-stop)
 The airfl ow amount may decrease
slightly while the i-stop function is
operating.
 


 Clear all obstructions such as leaves,
snow and ice from the bonnet and the
air inlet in the cowl grille to improve the
system effi ciency.




 Use the air-conditioning system to defog
the windows and dehumidify the air.
 


 The recirculate mode should be used
when driving through tunnels or while in
a traffi 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 windscreen defrosting.
 


 If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the air-conditioning 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
effi cient.

 The refrigerant specifi cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refi 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 expert repairer,
we recommend an Authorised Mazda
Repairer.
