4-1. 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 perio d of time with the ignition switched
ON when the engine is not running.
• Clear all obstructions such as l eaves, snow and ice from the hood
and the air inlet in t he cowl grille to imp rove the system efficiency.
• Use the climate control system to defog the windows and dehumi d-
ify the air.
• The recirculate mode should be used when driving through tunne ls
or while in a traffic jam, or when you would like to shut off o utside
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 con-
trol system.
• Run the air conditioner about 10 minutes at least once a month to
keep internal parts lubricated.
• Have the air conditioner checke d before the weather gets hot. Lack
of refrigerant may make the ai r 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 your Toyota
dealer.
