2805-1. Using the air conditioning system and defogger
■Operation of the air conditio ning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
● When the outside temperature exceeds 68°F (20°C), the air conditioning
system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● It is possible to switch to outside air mode at any time by pressing
.
●Engine speed and compressor operation controlled to restrict heating/cool-
ing 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
■ 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
immediately after is touched.
■ 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.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor ( →P. 282) 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 the out-
side/recirculated air mode to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant tem-
perature or inside temperature.

Interior features
■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 power switch
is turned to ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■When the outside temperat ure falls to nearly 32°F (0°C)
The dehumidification function may not operate even when is touched.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air m\
ode.
● 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:
• This vehicle is equipped with a deodorizing charcoal air filter. This filter
should be inspected and replaced according to the maintenance sched-
ule. (Air conditioning filter: →P. 371)
• 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.
■ Air conditioning filter
→P. 371
■ Handling of the air conditioning panel
The operating section of the air conditioning panel uses touch switch sensors.
In the following cases, incorrect operation or non-response may occur.
●If the surface of the touch switch is dirty or has liquid attached to it, incorrect
operation or non-response may occur.
● If the surface of the touch switch receives electromagnetic waves, incorrect
operation or non-response may occur.
● If wearing gloves during operation, non-response may occur.
● If fingernails are used to operate the system, non-response may occur.
● If a touch pen is used to operate the system, non-response may occur.
● If the palm of your hand touches the surface of the touch switch during oper-
ation, incorrect operation may occur.
● If the palm of your hand touches the surface of the touch switch, incorrect
operation may occur.
● If operations are performed quickly, non-response may occur.

2825-1. Using the air conditioning system and defogger
■Customization
Settings (e.g. air conditioning setting, touch switch sensitivity) can be
changed.
(Customizable features →P. 461)
WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surf aces when the outside rear view mirror
defoggers are on.
NOTICE
■ Humidity sensor
■ To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed.
Follow these points to avoid damaging
the sensor:
●Do not disassemble the sensor
● Do not spray the glass cleaner on the
sensor or subject it to strong impacts
● Do not stick anything on the sensor
