■Fogging up of the windows
●The windows will ea sily fog up when
the humidity in the vehicle is high.
Turning “A/C” s witch on will dehumid- ify the air from the outlets and defog
the windshield effectively.
●If you turn “A/C” switch off, the win -
dows may fog up more easily.
●The windows may fog up if the recir -
culated air mode is used.
■While using “My Room Mode”
●It may not be possible to obtain the
intended defogging performance even
if is pressed. If the windows
need to be defogged before driving,
stop charging powe r and then press
.
●When the outside te mperature is low,
heating may feel insufficient due to
restricted operation of the air condi -
tioning. Heating cannot be performed when it is -10°C (14° F) or less as the
gasoline engine cannot be started
during “My Room Mode”. If heating is desired, stop charging and remove
the AC charging cable from the vehi -
cle.
■When driving o n dusty roads
Close all windows. If dust thrown up by
the vehicle is still d rawn into the vehicle
after closing the windows, it is recom - mended 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 recir culated air mode
temporarily is recommended in pre - venting dirty air from entering the
vehicle interior and helping to cool the
vehicle when the ou tside air tempera- ture is high.
●Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside tem-
perature.
■Operation of the air conditioning system in Eco drive mode
●In Eco drive mode, the air conditioning system is controlled as follows to pri -
oritize fuel efficiency:
• Engine speed and compressor opera - tion controlled to res trict heating/cool-
ing capacity
• Fan speed restrict ed when automatic mode is selected
●To improve air conditioning perfor - mance, perform the following opera -
tions:
• Turn off Eco drive mode ( →P.434) • Turn off blower customization
( →P.454)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is
pressed.

●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning
system. This may t hen cause odor to
be emitted from the vents.
●To reduce potential odors from occur -
ring: • It is recommended that the air condi-
tioning system be se t to outside air
mode prior to turning the vehicle off. • The start timing o f the blower may be
delayed for a short period of time
immediately after t he air conditioning system is started in automatic mode.
