“AUTO” button
For automatic operation of the air condi-
tioning, press the “AUTO” 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, onoff of the air condi-
tioning and air intake according to the
temperature.
When you press the “AUTO” 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 “MAX COLD” 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.
To turn off the automatic operation, press
the “OFF” button.Fan speed selector

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

re—to the right to warm, to the left to
cool.
The temperature display changes between

2. Bilevel—Air flows from both the floor
vents and the instrument panel vents.
When you set the temperature selector
setting at about the middle in automatic
operation, warm air flows out of the
floor vents and relatively lowtempera-
ture air flows out of the center and
side vents.
3. Floor— Air flows mainly from the floor
vents.
It is recommended that you close the
lower vent. For details about this, see
“Instrument panel vents” on page 249
in this section.
4. Floor/Windshield— Air flows mainly
from the floor vents and windshield
vents.
Use with the air intake selector posi-
tioned in FRESH.
It is recommended that you close the
lower vent. For details about this, see
“Instrument panel vents” on page 249
in this section.
For details about air flow selector settings,
see “—Air flow selector settings” de-
scribed below.
Windshield air flow button
When this button is pressed, air flows
mainly from the windshield vents.
Pressing the button once again returns the
air flow mode to the last one used.
This button 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 RECIRCULATE
mode, press the air intake selector button
once again.
Press the “A/C” button for dehumidified
heating or cooling. This setting clears the
front view more quickly. It is recommended that you close the low-
er vent. For details about this, see “Instru-
ment panel vents” on page 249 in this
section.
For details about air flow selector settings,
see “—Air flow selector settings” de-
scribed below.

and fog, see “Instrument panel vents” on

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.
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. “A/C” button
To turn on the air conditioning, press the
“A/C” button. The “A/C” button indicator
will come on. To turn the air conditioning
off, press the button again.
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 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 “OFF”.
