—Air flow selector settings

—Operating tips

D 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.

D Make sure the air intake grilles in front

of the windshield are not blocked (by

leaves or snow, for example).

D 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.

D Keep the area under the front seats

clear to allow air to circulate through-

out the vehicle.

D On cold days, turn the fan speed se-

lector to “HI” for a minute to help clear

the intake ducts of snow or moisture.

This can reduce the amount of fogging

on the windows.

D 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”.

: See “Instrument panel vents” in this section.

D 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.
