• The windows will easily fog up when the humidity in the vehicle is high. Turning “A/C” switch is on will dehumidify the air from the outlets and defog the windshield effectively.
• If you turn “A/C” switch is off, the windows may fog up more easily.
• The windows may fog up if the recirculated air mode is used.

■ When driving on dusty roads

Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the air intake mode be set to outside air mode and the fan speed to any setting except off.

■ Outside/recirculated air mode

Setting to the recirculated air mode temporarily is recommended in preventing dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air temperature is high.

■ When the outside temperature falls to nearly 32°F (0°C)

The dehumidification function may not operate even when “A/C” switch is pressed.

■ Ventilation and air conditioning odors

• To let fresh air in, set the air conditioning system to the outside air mode.
• During use, various odors from inside and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to be emitted from the vents.
• It is recommended that the air conditioning system be set to outside air mode prior to turning the vehicle off.
• When parking, the system automatically switches to outside air mode to encourage better air circulation throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

■ Air conditioning filter

■Air conditioning system refrigerant

• A label regarding the refrigerant of the air conditioning system is attached to the hood at the location shown in the following illustration.

• The meaning of each symbol on the label are as follows:

WARNING

■ To prevent the windshield from fogging up

Do not use the windshield defogger switch during cool air operation in extremely humid weather. The difference between the temperature of the outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your vision.

■ When the outside rear view mirror defoggers are operating

(vehicles with outside rear view mirror defoggers) Do not touch the outside rear view mirror surfaces, as they can become very hot and burn you.

NOTICE

■To prevent battery discharge

Do not leave the air conditioning system on longer than necessary when the engine is off.

■When repairing/replacing parts of the air conditioning system

Have repair/replacement performed by your Toyota dealer. When a part of the air conditioning system, such as the evaporator, is to be replaced, it must be replaced with a new one.
