the air conditioning according to the tem-
perature.
When you push the “AUTO” button with
the air intake mode at FRESH, internal
circulation may be applied for maximum
cooling.
You may use manual controls if you want
to select your own settings.
Fan speed selector
Select the mode button you desire to ad-
just the fan speed and push it. An indica-
tor light will illuminate to show which fan
speed mode is being selected.
In automatic operation, you do not have
to adjust the fan speed unless you desire
another fan speed mode. Temperature selector
To increase the temperature, push the
“UP” side, to decrease it, push the
“DOWN” side.
“LO” appears when you adjust to maxi-
mum cooling, and “HI” appears when you
adjust to maximum warming.
“OFF” button
Push the “OFF” button to turn off the air
conditioning system.
Air flow selector
Push one of the buttons to select the
vents used for air flow. An indicator light
will illuminate to show which air flow
mode is being selected.
In automatic operation, you do not have
to select the air flow unless you desire
another air flow mode.

4. Floor/Windshield— Air flows mainly
from the floor vents and windshield
vents and fan speed may increase in
order to clean up the front view.
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 in-
take selector button once again.
5. Windshield— Air flows mainly from the
windshield vents and fan speed may
increase in order to clean up the front
view.
Pressing this 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.
It is not possible to return to RECIR-
CULATE in this mode.
For details about air flow selector settings,
see “Air flow selector settings” described
below.
Air intake selector
Push the button to select the air source.
An indicator light will illuminate to show
which the air source is being selected. 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. If the ambient temperature is low when
the ignition switch is turned to the “ON”
position, the air intake mode is always set
to FRESH even though the previous mode
was RECIRCULATE.
“A/C” button
To turn on the air conditioning, push the
“A/C” button. The
“A/C” button indicator
will come on. To turn the air conditioning
off, push 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”.
