Toyota Yaris: Climate Control System / Operating Tips

Toyota Yaris XP210 (2020-2026) Owner's Manual / Interior Features / Climate Control System / 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 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.
