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 mode

■

Using the voice command system

■

Fogging up of the windows

●

The windows will easily fog up when the humidity in the vehicle is high. Selecting

will dehumidify the air from the outlets and defog the windshield effectively.

●

If you turn

off, the windows may fog up more easily.

●

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

■

Outside/recirculated air mode

●

When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-

lated air mode button to the recirculated air mode. This is effective in preventing out-

side air from entering the vehicle interior. During cooling operation, setting the

recirculated air mode will also cool the vehicle interior effectively.

●

Outside/recirculated air mode may automatically switch depending on the tempera-

ture setting or the inside temperature.

■

When the outside temperature exceeds 75

F (24C) and the air conditioning system

is on

●

In order to reduce the air conditioning power consumption, the air conditioning 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 engine switch is turned to

IGNITION ON mode.

●

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

■

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.

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.

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

gers are on.
