Fogging up of the windows
●
The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield 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 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.
●
Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■
When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on

ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
●

is turned to “ON” position.
●
It is possible to switch to outside air mode at any time by pressing .
■
Ventilation and air conditioning odors

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.
