from the floor vents and windshield
vents.
Turning the air flow selector to the
floor/windshield position turns on the
defogging/defrosting function with the
purpose of clearing the windshield.
In this position, air intake selector
mode changes to FRESH automatically
to clear the windshield quickly. If you
want to return the setting to RECIRCU-
LATE mode, press the air intake selec-
tor button once again.
Press the “A/C” button for dehumidified
heating or cooling. This setting clears
the windshield more quickly.

ging/defrosting function and the air con-
ditioning with the purpose of clearing
the windshield.
In this position, air intake selector
mode changes to FRESH automatically
to clear the windshield quickly. It is not
possible to return to RECIRCULATE in
this position. In this position, the air conditioning
turns on regardless of the “A/C button
indicator comes on or goes off. This is
not a malfunction.
For details about air flow selector settings,
see “Air flow selector settings” described
below.
XS19014
Air intake selector
Press the button to select the air source.
1. Recirculate (indicator light is on)—Re-
circulates 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.

385
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
If the ambient temperature drops, the air
intake mode will automatically change
from RECIRCULATE to FRESH after a few
minutes. This automatic change control
mode can be cancelled by pushing and
holding the button for longer than 2 sec-
onds. The automatic change control mode
will be reactivated if the engine switch is
turned to the “LOCK” or “ACC” position.
“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.

:Independent setting
To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open long enough for the
hot air to escape. This operation allows
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”.

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 best results, set controls to:
Fan speed— Any setting except “OFF”
Temperature— Towards red zone
Air intake—FRESH (outside air)
Air flow—FLOOR

air for a few minutes. To keep the
windows from fogging, select fresh af-
ter the vehicle interior has been
warmed.
Press the “A/C” button on for dehumidi-
fied heating.
Choose floor/windshield air flow to heat
