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.

2−way air intake control

To improve fuel economy, “Fresh” mode

control changes when the air intake se-

lector is set in “Fresh” mode on the

following conditions:

The air intake selector button is used to

switch the air intake FRESH mode that

draws outside air into the system and RE-

CIRCULATED mode that recirculates the

air inside vehicle.

2. Economical and environment−friendly

cooling

Usually use the air conditioning with the

“A/C” button on. If you push the button

again, the air conditioning turns off.

To turn the air source to RECIRCULATED

mode, press the button. The indicator will

come on. To turn the air source to FRESH

mode, press the button again. The indica-

tor will go off.

For economical and environment−friend-

ly use

If the air conditioning does not work well

with the “A/C” button on, push the “MAX”

button. To cancel the “MAX” mode, push

the “MAX” button again. To turn off the air

conditioning, push the “A/C” button.

Usually, use the air conditioning with the

“A/C” button on (economical and environ-

ment−friendly cooling).

In this mode the gasoline engine starts

and stops automatically and good fuel

economy driving is achieved.

With the “MAX” button on, the gasoline

engine is frequently used.

The air conditioning may not turn on with

the selector lever in “N” position because

the gasoline engine cannot start.

To use the air conditioning in economi-

cal and environment−friendly way, we

recommend the following setting:

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 your Toyota dealer for service.

1. Lower the setting temperature if you

feel a little hot with the “A/C” button

on.

2. If you feel still hot with the “A/C” but-

ton on, push the “MAX” button also.

After the compartment cools, turn off

the “MAX” mode only.

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.

27p005

D Keep the area under the front seats

clear to allow air to circulate through-

out the vehicle.

D 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.

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”.

136

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.

tures could make the fogging worse.
