ªAUTOº button
For automatic operation of the air condi-
tioning, press the ªAUTOº button. An indi-
cator light will illuminate to show that the
automatic operation mode has been se-
lected.
In the automatic operation mode, the air
conditioning selects the most suitable fan
speed and air flow, on±off of the air condi-
tioning and air intake according to the
temperature.
When you press the ªAUTOº button with
the air intake mode at FRESH, internal
circulation may be applied for maximum
cooling.
When you adjust the temperature selector
to maximum cooling, a ªMAX COLDº mes-
sage will appear on the display and the
air intake mode will be automatically
changed to RECIRCULATE.
You may use manual controls if you want
to select your own settings.Fan speed selector

crease.
In automatic operation, the fan speed is
adjusted automatically unless you desire
another fan speed mode.

Turn the knob to adjust the temperatu-
reÐto the right to warm, to the left to
cool.

It is recommended that you close the low-
er vent. For details about this, see ªInstru-
ment panel ventsº on page 297 in this
Section.
For details about air flow selector settings,
see ªÐAir flow selector settingsº de-
scribed below.
For further information for removing frost
and fog, see ªInstrument panel ventsº on
page 297 in this Section.
Air intake selector button
Press the button to select the air source.
1. RECIRCULATEÐRecirculates the air in-
side the vehicle.
2. FRESHÐDraws outside air into the
system.
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.
For example, when the ambient tempera-
ture is low, the air intake mode may
change automatically to FRESH. This is
not a malfunction.When the ignition switch is turned to the
ªONº position, the air intake mode is al-
ways set to FRESH even if the previous
mode was RECIRCULATE.
ªA/Cº button
To turn on the air conditioning, press the
ªA/Cº button. The ªA/Cº button indicator
will come on. To turn the air conditioning
off, press the button again.
If the ªA/Cº 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 a Toyota dealer for service.

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 ªOFFº.

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

interior.Heating

Pressing the windshield air flow button
turns on the defogging function with the
purpose of clearing the front view.When pressing the windshield air flow but-
ton, the air intake selects FRESH auto-
matically and fan speed may increase.
This is to clean up the front view more
quickly. It is not possible to return to RE-
CIRCULATE in this mode.
Press the ªA/Cº button for dehumidified
heating or cooling. This setting clears the
front view more quickly.

On humid days, do not blow cold air
on the windshieldÐthe difference be-
tween the outside and inside tempera-
tures could make the fogging worse.
