Defogging the windshield

Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.

Set the outside/recirculated air mode but-
ton to outside air mode if the recirculated
air mode is used. (It may switch automati-
cally.)

Fogging up of the windows

The windows will easily fog up when the

humidity in the vehicle is high. Selecting

“A/C” on will dehumidify the air from the

outlets and defog the windshield effectively.

●

If you turn “A/C” off, the windows may fog

up more easily.

●

The windows may fog up if the recircu-

lated air mode is used.

■

When driving on dusty roads

Close all windows. If dust thrown up by the

vehicle is still drawn into the vehicle after

closing the windows, it is recommended

that the air intake mode be set to outside air

mode and the fan speed to any setting

except off.

■

Outside/recirculated air mode

●

Setting to the recirculated air mode tem-

porarily is recommended in preventing

dirty air from entering the vehicle interior

and helping to cool the vehicle when the

outside air temperature is high.

●

Outside/recirculated air mode may auto-

matically switch depending on the tem-

perature setting or the inside

temperature.

■

Registering air conditioning settings to

electronic keys (vehicles with driving

position memory)

●

Unlocking the vehicle using an electronic

key and turning the engine switch to

IGNITION ON mode will recall that

key’s registered air conditioning settings.

●

When the engine switch is turned off, the

current air conditioning settings will auto-

matically be registered to the electronic

key that was used to unlock the vehicle.

●

The system may not operate correctly if

more than one electronic key is in the

vicinity or if the smart entry & start system

is used to unlock a passenger door.

●

The doors that can recall the air condi-

tioning setting when unlocked using the

smart entry & start system can be
changed.

■

Operation of the air conditioning sys-

tem in Eco drive mode

In Eco drive mode, the air conditioning sys-

tem 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.391)

■

When the outside temperature falls to

nearly 0°C (32°F)

The dehumidification function may not

operate even when “A/C” is selected.

■

Ventilation and air conditioning odors

●

To let fresh air in, set the air conditioning

system to the outside air mode.

●

During use, various odors from inside and

outside the vehicle may enter into and

accumulate in the air conditioning sys-

tem. This may then cause odor to be

emitted from the vents.

●

To reduce potential odors from occur-

ring:

• It is recommended that the air condition-

ing 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 imme-

diately after the air conditioning system is

started in automatic mode or pollen

removal mode.

■

When the Heated Windshield Defroster

is operating (if equipped)

When the Heated Windshield Defroster is

operating, operation of the heated steering

wheel, front passenger seat heater and rear

seat heaters will be suspended.

WARNING

■

To prevent the windshield from fog-

ging up

Do not use the windshield defogger

switch 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.

■

When the outside rear view mirror

defoggers are operating

Do not touch the outside rear view mir-

ror surfaces, as they can become very

hot and burn you.

To prevent battery discharge

Do not leave the air conditioning system

on longer than necessary when the

Outside air mode switches to

(recirculated air) mode. Pollen is removed

from the air and the air flows to the upper

In order to prevent the windshield from fog-

ging up when the outside air is cold, the

dehumidification function may operate or

the outside/recirculated air mode may not
switch to

(recirculated air) mode.

Pollen is filtered even if the pollen removal

mode is turned off.

■

nanoe™ system (if equipped)

This vehicle incorporates a biocidal prod-

uct.

Ionised air generated by a device incorpo-

rated in the vehicle purifies the air in the

cabin by suppressing bacteria.

Active substance: Free radicals generated

in situ from ambient air or water

nanoe™ helps to provide purified air by

emitting electrically charged water parti-

cles through the window side air outlet of

the driver’s seat*.

●

When the fan is turned on and nanoe™

on the option control screen is selected,

the nanoe™ system is activated.

●

When the fan is operated in the following

conditions, system performance will be

maximized. If the following conditions are

not met, performance will be limited.

• The

air outlets are

being used.

• The window side air outlet of the driver’s

seat is open.

●

When nanoe™ is generated, a small

amount of ozone is emitted and may be

faintly smelled in some situations. How-

ever, this is approximately the same as the

amount that already exists in nature, such

422

as in forests, and it has no affect on the

human body.

●

A slight noise may be heard during oper-

ation. This is not a malfunction.

: According to temperature and humidity

conditions, fan speed and direction of
the air flow, the nanoe™ system may not
operate at full capacity.

Press the automatic mode switch or
select “AUTO” on the sub function
menu. (

Press the outside/recirculated air
mode switch to switch to automatic

If the fan speed setting or air flow modes

are operated, the automatic mode indica-

tor goes off. However, automatic mode for

functions other than that operated is main-

tained.

■

Using automatic mode

Fan speed is adjusted automatically accord-

ing to the temperature setting and the

ambient conditions.
Therefore, the fan may stop for a while until

warm or cool air is ready to flow immedi-

ately after the automatic mode switch is

pressed or “AUTO” is selected.
Cool air may blow around the upper body

even when the heater is on due to sunlight.

■

Automatic mode for air intake control (if

equipped)

In automatic mode, the system detects

exhaust gas and other pollutants and auto-

matically switches between outside air and

recirculated air modes.
When the dehumidification function is off,

and the fan is operating, turning automatic

mode on will activate the dehumidification

function.

This function automatically controls the
air conditioning airflow so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver's
seat. Unnecessary air conditioning is
suppressed, contributing to increased
