Mazda 6 Owners Manual: Operating Tips
- Operate the climate control 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.
- 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. 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 Authorized Mazda Dealer.
