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 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 dehumid-

ify 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 con-

trol 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 your Toyota

dealer.

When using the air conditioner under humid ambient temperature conditions,

the system may blow fog from the vents. This is not a sign of trouble but a

result of humid air being suddenly cooled.

4-1. Climate Control System

■ Temperature control dial

This dial controls temperature. Turn it clockwise for hot and coun-

terclockwise for cold.

■ Fan control dial

This dial allows variable fan speeds.

The fan has seven speeds.

■ Mode selector dial

Turn the mode selector dial to select airflow mode (P. 258).

■ A/C switch

Press the A/C switch to turn the air conditioner on. The indicator

light on the switch will illuminate when the fan control dial is in any

position except OFF.

■ Air intake selector

This switch controls the source of air entering the vehicle.

Press the air intake selector switch to alternate between the outside

air and recirculated air positions.

● Recirculated air position (

Outside air is shut off. Air within the vehicle is recirculated.

● Outside air position (

)

Outside air is allowed to enter the cabin. Use this mode for venti-

lation or windshield defrosting.

with the fan control dial in a position

other than 0 and the temperature control dial in the maximum cold position,

the air intake selector switches to the recirculated air position and the A/C

turns on automatically. If A/C is not desired, press the A/C switch to turn it off.

■Mode selector dial

●The mode selector dial can be set at the intermediate positions (

between each mode. Set the dial to an intermediate position if you want to

split the airflow between the two modes.

)

●For example, when the mode selector dial is at the

position between

the

and

positions, airflow from the floor vent is less than that of

the

position.

■A/C switch

The air conditioner may not function when the outside temperature

approaches 32 °F (0 °C).

WARNING

■Do not use the recirculated air position in cold or rainy weather

Using the recirculated air position in cold or rainy weather is dangerous as it

will cause the windows to fog up. Your vision will be hampered, which could

lead to a serious accident.

NOTICE

If the air conditioner is used while driving up long hills or in heavy traffic,

monitor the engine coolant temperature warning light to see if it is illumi-

nated or flashing (P. 164).

The air conditioner may cause engine overheating. If the warning light is

illuminated or flashing, turn the air-conditioning off (P. 484).

humidity, the windshield may fog up more easily.

●Setting the temperature to maximum hot or cold will not provide the desired

temperature at a faster rate.

In this position, the outside air position is automatically selected, and

when the fan control dial is ON, the air conditioner automatically turns

on. The air conditioner will directly dehumidify the air to the front wind-

shield and side windows (P. 258). Airflow amount will be increased.

Use the temperature control dial to increase the air flow temperature and

defog the windshield more quickly.

WARNING

■Set the temperature control to the hot or warm position when defog-

ging (

Using the

position with the temperature control set to the cold posi-

tion is dangerous as it will cause the outside of the windshield to fog up.

Your vision will be hampered, which could lead to a serious accident.
