■

When the outside temperature

exceeds 75°F (24°C) and the air

conditioning system is on

●

In order to reduce the air condi-

tioning power consumption, the air

conditioning system may switch to

recirculated air mode automati-

cally. This may also reduce fuel

consumption.

featur

recirculated 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 temporarily is recom-

mended 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 temperature setting or the

inside temperature.

■

Operation of the air condition-

ing system in Eco drive mode

●

In Eco drive mode, the air condi-

tioning system is controlled as fol-

lows to prioritize fuel efficiency:

• Engine speed and compressor

operation controlled to restrict

heating/cooling capacity

• Fan speed restricted when auto-

matic mode is selected

●

To improve air conditioning perfor-

mance, perform the following

operations:

• Adjust the fan speed

• Turn off Eco drive mode (



P.300)

■

When the outside temperature

is low

The dehumidification function may

not operate even when the “A/C”

switch is pressed.

■

Ventilation and air conditioning

odors

●

To let fresh air in, set the air condi-

tioning 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 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 out-

side 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 con-

ditioning system is started in auto-

matic mode.

●

When parking, the system auto-

matically switches to outside air

mode to encourage better air cir-

culation throughout the vehicle,

helping to reduce odors that occur

when starting the vehicle.

■

Air conditioning system opera-

tions when the engine is

stopped due to the Stop & Start

system (vehicles with Stop &

Start system)

When the engine is stopped due to

Stop & Start system operations, the

automatic air conditioning cooling,

heating and dehumidification func-

tions turn off and the fan speed is

decreased according to the outside

temperature etc. or air blowing

stops. To stop the air conditioning

system from turning off, press the

Stop & Start cancel switch and

refrain from using the Stop & Start

system.

■

WARNING

■

To prevent the windshield

from fogging up

Do not use the windshield defog-

ger switch during cool air opera-

tion in extremely humid weather.

The difference between the tem-

perature of the outside air and

that of the windshield can cause

the outer surface of the wind-

shield to fog up, blocking your

vision.

■

When the outside rear view

mirror defoggers are operat-

ing

Do not touch the rear view mirror

surfaces when the outside rear

view mirror defoggers are on.

■

When the windshield wiper

de-icer is operating
