3-1. Using the air conditioning system and defogger

■Using the automatic mode

Fan speed is adjusted automatically in accordance with the temperature set-

ting and ambient conditions. As a result, the following may occur.

●Immediately after

is pressed, the fan may stop for a while until

warm or cool air is ready to flow.

●Cool air may flow to the area around the upper body when the heater is

on.

■Switching between outside air and recirculated air modes

Recirculated air mode or outside air mode may be automatically switched to

in accordance with under these condition, such as temperature setting and

inside temperature.

3

Also, outside air mode may be automatically switched to when the outside

temperature is low.

■When the outside temperature exceeds 75 F (24 C) and the air condi-

tioning system is on

●In order to reduce the air conditioning power consumption, the air condi-

tioning system may switch to recirculated air mode automatically. This

may also reduce fuel consumption.

●Recirculated air mode is selected as a default mode when the “POWER”

switch is turned to ON mode.

●It is possible to switch to outside air mode at any time by pressing

.

■Using the system in recirculated air mode

The windows will fog up more easily if the recirculated air mode is used.

■Window defogger feature

●Recirculated air mode may automatically switch to outside air mode in

situations where the windows need to be defogged.

●When the outside air temperature is low, it may take a while for the con-

densation to clear from the windshield.

333

3-1. Using the air conditioning system and defogger

■When

is selected for the air outlets used

For your driving comfort, air flowing to the feet may be warmer than air flow-

ing to the upper body depending on the temperature setting.

■Micro dust and pollen filter

●In order to prevent the windows from fogging up when the outside air is

cold, the following may occur.

• Outside air mode does not switch to recirculated air mode.

• The air conditioning system operates automatically.

• The operation cancels after 1 minute.

●In rainy weather, the windows may fog up. Press

.

●Condensation may appear on the windows if this mode is used in abnor-

mally high levels of humidity.

●Pollen will be collected by the filter even when micro dust and pollen filter

mode is OFF.

■Maintenance of the air conditioning filter

The air conditioning filter must be cleaned or changed regularly to maintain

air conditioning efficiency according to the maintenance schedule. In dusty

areas or areas with heavy traffic flow, early replacement may be required.

(For scheduled maintenance information, refer to the “Owner’s Manual Sup-

plement/ Scheduled Maintenance Guide”.)

When inspecting, cleaning and replacing the air conditioning filter, contact

your Toyota dealer.

334

3-1. Using the air conditioning system and defogger

■If air flow from the vents decreases dramatically

The filter may be clogged. Contact your Toyota dealer.

■Operation of the air conditioning system in Eco drive mode

In the Eco drive mode, the air conditioning system is controlled as follows to

prioritize fuel efficiency:

●Engine speed and compressor operation controlled to restrict heating/

cooling capacity

●Fan speed restricted when automatic mode is selected

To improve air conditioning performance, perform the following operations:

●Adjust the fan speed

●Turn off Eco drive mode (P. 204)

3

●Customize the air conditioning control of Eco drive mode. (P. 590)

■When outside air temperature is below 32 °F (0 °C)

The cooling and dehumidification function may not operate even when

is pressed.

■Air conditioning odors

●During use, various odors from inside and outside the vehicle may enter

into and accumulate in the air conditioning system. This may then cause

odor to be emitted from the vents.

●To reduce potential odors from occurring:

• It is recommended that the air conditioning system be set to outside air

mode prior to turning the vehicle off.

• The start timing of the blower may be delayed for a short period of time

immediately after the air conditioning system is started in automatic

mode.

■Customization

Settings (e.g. enable/disable automatic operation of the air conditioning

compressor when the “AUTO” switch ON) can be changed.

(Customizable features P. 590)

335

3-1. Using the air conditioning system and defogger

CAUTION

■To prevent the windshield from fogging up

Do not use

during cool air operation in extremely humid weather.

The difference between the temperature of the outside air and that of the

windshield can cause the outer surface of the windshield to fog up, blocking

your vision.

NOTICE

■To prevent 12-volt battery discharge

Do not leave the air conditioning system on longer than necessary when the

hybrid system is not operating.
