your Lexus dealer.
*: The doors that can recall the driving position memory are changed at the
same time.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until
warm or cool air is ready to flow immedi-
ately after is pressed or “AUTO” is
selected.
■Using the voice command system
Air conditioning system can be operated
using voice commands. Fo r details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■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 (“A/C”) off, the win-
dows may fog up more easily.
●The windows may fog up if the recircu-
lated 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 tem-
porarily is recommended 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 auto-
matically switch de pending 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
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
.
■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 condit ioning 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 is pressed or
“A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
