2021 Mazda 3 Owners Manual - Operating Tips



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/switch on for a long period of time with the ignition switched ON when the engine is not running.
  • (With i-stop) The airflow 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 efficiency.
  • 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 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 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 efficient. The refrigerant specifications are indicated on a label attached to the inside of the engine compartment. Check the label before refilling 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.
