Air flow selector settings Operating tips

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, move the fan speed to
ªHIº for a minute to help clear the in-
take 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 ªOFFº.

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.
