air flow mode to the last one used.
Pressing the windshield button turns on
the defroster −linked air conditioning. At
this time, the air conditioning turns on
regardless of the “A/C” button indicator
comes on or goes off. This is not a mal-
function. This is to clean up the front view
more quickly.
For details about air flow selector settings,
see “Air flow selector settings” described
below.

Air intake selector
Press the button to select the air source.
1. RECIRCULATE (indicator light is on)—
Recirculates the air inside the vehicle.
2. FRESH (indicator light is off)—Draws
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.

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.

and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to a Toyota dealer for service.

:Independent setting
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 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 to any set-
ting except off.

Air conditioning filter—
XS19017
The air conditioning filter information
label is placed inside of the glove box
as shown and indicates that a filter has
been installed.
The air conditioning filter prevents dust
from entering the vehicle through the air
conditioning vent.
XS19007
The air conditioning filter is behind the
glove box. The air conditioning filter may clog af-
ter long use. The filter may need to be
replaced if the air flow of the air condi-
tioning and heater experiences extreme
reductions in operating efficiency, or if
the windows begin to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance
schedule. In dusty areas or areas with
heavy traffic flow, such as inner city or
desert areas, early replacement may be
required. (For scheduled maintenance
information, please refer to the “Scheduled
Maintenance Guide” or “Owner ’s Manual
Supplement.”)

outlet, keep the arrow pointing up.
INFORMATION
The air filter should be installed prop-
erly in position. The use of air condi-
tioning with the air filter removed
may cause deteriorated dustproof per-
formance and then affect air condi-
tioning performance.
