■Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
● When stopped, or driving at low speeds (less than 16 mph [25 km/h])
● When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
■ Operation of the air conditio ning system in Eco drive mode
In the Eco drive mode, the air conditioning system 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 ( P. 187)
● Customize the air conditioning control of Eco drive mode. ( P. 529)
■ When outside air temperature is below 32 F (0 C)
The cooling and 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.

compressor when the “AUTO” switch ON) can be changed.
(Customizable features P. 529)
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 wind-
shield 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.
