“AUTO” position (for fan speed)
For automatic operation of the air condi-
tioning, turn the fan speed selector knob
to “AUTO” position.
In the automatic operation mode, the air
conditioning selects the most suitable fan
speed according to the temperature.
You may use manual controls if you want
to select your own settings.
Fan speed selector
Turn the knob to adjust the fan speed—to
the right to increase, to the left to de-
crease.
In automatic operation, you do not have
to adjust the fan speed unless you desire
another fan speed mode.
Temperature selector
Turn the knob to adjust the temperature
to the right to warm and then to the left
to cool.
27p002
Air flow selector
Turn the knob to select the vents used for
air flow.1. Panel— Air flows mainly from the
instrument panel vents.
2. Bilevel— Air flows from both the floor
vents and the instrument panel vents.
3. Floor— Air flows mainly from the floor
vents.
4. Floor/Windshield— Air flows mainly
from the floor vents and windshield
vents.
This position allows the air intake to
select FRESH automatically. This is to
clean up the front view more quickly. If you want to return the setting to RE-
CIRCULATE mode, press the air intake
selector button once again.
Press the “A/C” and “MAX” button for
dehumidified heating or cooling. This
setting clears the front view more
quickly.
5. Windshield— Air flows mainly from the
windshield vents.
Turning the air flow selector to the
windshield position turns on the defog-
ging function with the purpose of clear-
ing the front view.
This position allows the air intake to
select FRESH automatically. This is to
clean up the front view more quickly.
If you want to return the setting to RE-
CIRCULATE mode, press the air intake
selector button once again.
For details about air flow selector settings,
see “Air flow selector settings” on page

Air intake selector
Press the button to select the air source.1. Recirculate— Recirculates the air inside
the vehicle.
2. Fresh— Draws outside air into the sys-
tem.
The air intake selector button is used to
switch the air intake FRESH mode that
draws outside air into the system and RE-
CIRCULATED mode that recirculates the
air inside vehicle.
To turn the air source to RECIRCULATED
mode, press the button. The indicator will
come on. To turn the air source to FRESH
mode, press the button again. The indica-
tor will go off. To prevent fogging up of the windshield,
the air intake mode may change automati-
cally to FRESH depending on the condi-
tion of the air conditioning system.
2way air intake control
To improve fuel economy, “Fresh” mode
control changes when the air intake se-
lector is set in “Fresh” mode on the
following conditions:
When the maximum heating is needed
with the air flow in “Floor” or “Floor/
Windshield”, fresh air flows in the up-
per compartment, while air is recircu-
lated in the lower compartment.
When cooling is needed, both fresh
and recirculate modes turns on.

Air conditioning onoff buttons
To turn on the air conditioning, push
the “A/C” button.
1. Turning off the air conditioning
Push the “A/C” button to turn off the air
conditioning. 2. Economical and environmentfriendly cooling
Usually use the air conditioning with the
“A/C” button on. If you push the button
again, the air conditioning turns off.

139
3. Powerful cooling and dehumidifying
If the air conditioning does not work well
with the “A/C” button on, push the “MAX”
button. To cancel the “MAX” mode, push
the “MAX” button again. To turn off the air
conditioning, push the “A/C” button.
With the “MAX” button on, the gasoline
engine is frequently used.
The air conditioning may not turn on with
the selector lever in “N” position because
the gasoline engine cannot start.
If the “A/C” button indicator flashes, there
is a problem in the air conditioning system
and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to your Toyota dealer for service. For economical and environmentfriend-
ly use
Usually, use the air conditioning with the
“A/C” button on (economical and environ-
mentfriendly cooling).
In this mode the gasoline engine starts
and stops automatically and good fuel
economy driving is achieved.
To use the air conditioning in economi-
cal and environmentfriendly way, we
recommend the following setting:
1. Lower the setting temperature if you feel a little hot with the “A/C” button
on.
2. If you feel still hot with the “A/C” but- ton on, push the “MAX” button also.
After the compartment cools, turn off
the “MAX” mode only.

Air flow selector settings92.Operating tips93.
To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
On cold days, set the fan speed to
high for a minute to help clear the
intake ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.
When driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake selector be set to
FRESH and the fan speed selector to
any setting except “OFF”.

141

If following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake selector be temporarily set to
RECIRCULATE, which will close off the
outside passage and prevent outside
air and dust from entering the vehicle
interior.
Heating

For quick heating, select recirculated
air for a few minutes. To keep the
windows from fogging, select fresh af-
ter the vehicle interior has been
warmed.
Press the “MAX” button on for dehu-
midified heating.
Choose “Floor/Windshield” air flow to
heat the vehicle interior while defrost-
ing or defogging the windshield. Air conditioning
For best results, set controls to:
Fan speed—
“AUTO”
Temperature— To the desired
temperature
Air intake—FRESH (outside air)

Defogging
The inside of the windshield
For best results, set controls to:
Fan speed—“AUTO”
Temperature— Towards high temperature
to heat;
low temperature to cool
Air intake—FRESH (outside air)
Air flow—WINDSHIELD
Air conditioning—”MAX” ON
Turning the air flow selector to the wind-
shield position turns on the defogging
function with the purpose of clearing the
front view.
When turning the air flow selector to wind-
shield or floor/windshield position, the air
intake selects FRESH automatically. This
is to clean up the front view more quickly.
If you want to return the setting to RE-
CIRCULATE mode, press the air intake
selector button once again.
On humid days, do not blow cold air
on the windshield—the difference be-
tween the outside and inside tempera-
tures could make the fogging worse. Defrosting
The outside of the windshield
For best results, set controls to:
Fan speed—
“AUTO”
Temperature— Towards high temperature
