Fogging up of the windows

●

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 out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculated air mode will also cool the vehicle
interior effectively.

temperature setting or the inside temperature.

When the outside temperature exceeds 75

°F (24°C) and the air condition-

ing system is on

●

In order to reduce the air conditioning power consumption, the air condition-
ing 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 the “ON” position (vehicles without a smart key system) or IGNI-
TION ON mode (vehicles with a smart key system).

●

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 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.
