■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:
● Heating/cooling capacity is restricted.
● Outside/recirculated air mode may automatically switch depending on
the temperature setting or the inside temperature.
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed or the temperature setting
● 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 pressed.
■ 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
windshield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.

Interior features
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior. Dur-
ing 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 condi-
tioning system is on
● In order to reduce the air conditioning power consumption, the air condi-
tioning 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 the “ON” position (vehicles without a smart key sys-
tem) or the “POWER” switch is turned to ON mode (vehicles with a smart
key system).
● It is possible to switch to outside air mode at any time by pressing
.
■ When the outside temperature falls to nearly 32 F (0 C)
The dehumidification function may not operate even when is
pressed.
■ Air conditioning odors
●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 immediately after the air conditioning system is started in automatic
mode.

(Customizable features P. 522)
CAUTION
■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, blocking
your vision.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
