■

Registering air conditioning settings to electronic keys (vehicles with a smart entry &

start system)

●

Unlocking the vehicle using an electronic key and turning the power switch to ON

mode will recall that key’s registered air conditioning settings.

●

When the power switch is turned off, the current air conditioning settings will automati-

cally 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.

■

Using automatic mode

Fan speed is adjusted automatically according to the temperature setting and the ambi-

ent conditions.

Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately

after the “AUTO” button is pressed or “AUTO” is selected.

■

Fogging up of the windows

●

The windows will easily fog up when the humidity in the vehicle is high. Pressing “A/C”

button or selecting “A/C” will dehumidify the air from the outlets and defog the wind-

shield effectively.

●

If you turn “A/C” off, the windows may fog up more easily.

●

The windows may fog up if the recirculated air mode is used.

■

Windshield fog detection function (if equipped)

When automatic mode is set, the humidity sensor (



P. 556) detects fog on the wind-

shield and controls the air conditioning system to prevent fog.

■

When driving on dusty roads

Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after clos-

ing 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 temporarily 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 automatically switch depending on the tempera-

ture setting or the inside temperature.

When the outside temperature is low

The dehumidification function may not operate even when “A/C” is pressed or “A/C” is

selected.

■

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

• Customize the air conditioning control of Eco drive mode. (



P. 748)

■

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 accu-

mulate 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.

WARNING

■

To prevent the windshield from fogging up

●

Do not use

during cool air operation in extremely humid weather. The differ-

ence 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.

■

To prevent burns

●

Do not touch the rear view mirror surfaces when the outside rear view mirror defog-

gers are on.

●

Do not touch the glass at lower part of the windshield or to the side of the front pillars

when the windshield wiper de-icer is on. (vehicles with windshield wiper de-icer)

NOTICE

■

Humidity sensor (if equipped)

■

To prevent 12-volt battery discharge

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

tem is off.

●

Do not place anything on the instrument

panel which may cover the air outlets. Other-

wise, air flow may be obstructed, preventing

the windshield defoggers from defogging.

In order to detect fog on the windshield, a sen-

sor which monitors the temperature of the

windshield, the surround humidity, etc. is

installed. (



P. 554)

Follow these points to avoid damaging the sen-

sor:

●

Do not disassemble the sensor

●

Do not spray the glass cleaner on the sensor

or subject it to strong impacts

●

Do not stick anything on the sensor
