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 conditioning—OFF
For quick heating, select recirculated
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.

Defogging
The inside of the windshield
For best results, set controls to:Fan speed— Any setting except “OFF”
Temperature— Towards red zone to heat;
blue zone to cool
Air intake—FRESH (outside air)
Air flow—WINDSHIELD
Turning the air flow selector to the wind-
shield or floor/windshield position turns on
the defogging function with the purpose of
clearing the front view.
When turning the air flow selector to wind-
shield or floor/windshield position, the air
intake selects FRESH automatically. This
is to clean up the front view more quickly.
If you want to return the setting to RE-
CIRCULATE 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.
If you turn the air flow selector to the
another position, the air intake mode re-
turns to FRESH mode automatically.
On humid days, do not blow cold air
on the windshield—the difference be-
tween the outside and inside tempera-
tures could make the fogging worse.

If air flow control is not satisfactory, check
the side vents. The side vents may be
opened or closed as shown.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 in
FRESH mode.
To keep the air conditioning efficiency, re-
place the filter following the interval below;
U.S.A.—Every 22500 miles∗
Canada—Every 16000 km
∗: If you drive your vehicle on dusty roads
mostly, replace the filter every 10000
miles.
1. Open the glove box. Remove the screw with a Phillips head screw-
driver and slide off the damper as
shown.

The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogged up in the rain. However,
if there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer.Light bulbsBulb
