To defog the windshield and the side windows early, turn the air flow and
temperature up.

To return to the previous mode, press 

 again when the windshield

is defogged.

■

Defogging the rear window and outside rear view mirrors (if
equipped)

Defoggers are used to defog the rear window, and to remove rain-
drops, dew and frost from the outside rear view mirrors.

Before operating the defoggers, make sure the back window is
completely closed. (

→P. 152)

Press

The defoggers will automatically turn off after their operation time. The
operation time varies depending on the ambient temperature and vehi-
cle speed.

■

Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.

Therefore, the fan may stop for a while until warm or cool air is ready to flow

immediately after 

 is pressed.

■

Fogging up of the windows

●

The windows will easily fog up when the humidity in the vehicle is high.

Turning 

 on will dehumidify the air from the outlets and defog the wind-

shield effectively.

●

If you turn 

 off, the windows may fog up more easily.

●

The windows may fog up if the recirculated air mode is used.

■

Outside/recirculated air mode

●

When driving on dusty roads, in tunnels, or in heavy traffic, set the outside/
recirculated air mode to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling opera-
tion, setting the recirculated air mode will also cool the vehicle interior
effectively.

●

Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant tem-
perature or inside temperature.

■

When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning system is on

●

In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.

●

Recirculated air mode is selected as a default mode when the engine switch
is turned to the “ON” position.

●

It is possible to switch to outside air mode at any time by pressing

 

.

■

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

The dehumidification function may not operate even when 

 is pressed.

■

When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle 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.

■

When the indicator light on 

 flashes

Press 

 

to turn off the cooling and dehumidification function and turn it on

again. There may be a problem in the air conditioning system if the indicator
light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.

■

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.

●

To reduce potential odors from occurring:

• It is recommended that the air conditioning system be set to outside air

mode prior to turning the vehicle off.

• The start timing of the blower may be delayed for a short period of time

immediately after the air conditioning system is started in automatic
mode.

WARNING

■

To prevent the windshield from fogging up

●

Do not use 

 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, block-
ing your vision.

■

To prevent burns

●

Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers are on.

●

Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on.

NOTICE

■

To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

●

Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
