Fogging up of the windows
■
The windows will easily fog up when the
humidity in the vehicle is high. Turning
("A/C") on will dehumidify the air
from the outlets and defog the windshield
effectively.
● If you turn
dows may fog up more easily.
The windows may fog up if the recircu-
●
lated air mode is used.
■ Outside/recirculated air mode
● When driving on dusty roads such as tun-
nels or in heavy traffic, set the out-
side/recirculated air mode button to the
recirculated air mode. This is effective in
preventing outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirculated air mode will
also cool the vehicle interior effectively.
● Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature 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

is pressed or "AUTO" is
("A/C") off, the win-
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

Automatic mode for air intake control
■
In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidification function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function.
Operation of the air conditioning sys-
■
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem 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
■ When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when
"A/C" is selected.
■ 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 sys-
tem. This may then cause odor to be
emitted from the vents.
