■Switching between outside air and recirculated air modes
Press .
The mode switches among (recirculated air mode), automatic and (outside air mode) modes each time the button is pressed.
When the system is switched to automatic mode, the air conditioning system
operates automatically.
■Defogging the windshield
Defoggers are used to defog the windshield and front side windows.
Press .
Set to outside air mode if the recirculated air mode is used. (It
may switch automatically.)
To defog the windshield and the side windows early, turn the air flow and tem-
perature up.

Interior features
■Using automatic mode
Fan speed is adjusted automatically according 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 the “AUTO” button is pressed or “AUTO” is selected.
■When the outside temperature exceeds 75 °F (24 °C) and the air conditioning sys-
tem 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 “START STOP
ENGINE” <“POWER”> switch is turned to IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on the option control screen will dehumidify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Windshield fog detection function (if equipped)
When automatic mode is set, the humidity sensor (→P. 476) detects fog on the
windshield and controls the air conditioning system to prevent fog.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set to
the recirculated air mode. This is effective 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 tem-
perature setting or the inside temperature.
■When the outside temperature is low
The dehumidification function may not operate even when “A/C” on the option con-
trol screen is selected.

ES350_300h_OM_OM33B36U_(U)
■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.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the micro dust and pollen filter is turned off.
■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning sy stem is controlled as follows to priori-
tize 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
■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 immedi- ately after the air conditioning system is started in automatic mode.

NOTICE
■To avoid the compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror.
Doing this may cause the compass sensor to malfunction.
■To ensure normal operation of the compass
●Do not perform a circling calibration of the compass in a place where the earth’s
magnetic field is subject to interference by artificial magnetic fields.
●During calibration, do not operate electric systems (moon roof, power windows,
etc.) as they may interfere with the calibration.
