mode toggles as follows.
Normal  “ECO”  “FAST”  Nor-
mal
When “ECO” is displayed on the air
conditioning screen, the air condi-
tioning is controlled with low fuel
consumption prioritized such as
reducing fan speed, etc.
When “FAST” is displayed on the
screen, fan speed will be
increased.
■Fogging up of the windows
●The windows will easily fog up when
the humidity in the vehicle is high. Turning “A/C” on will dehumidify the air from the outlets and defog the

Interior features
windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recir-culated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn 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 recirculated air mode temporarily is recommended in pre-
venting dirty air from entering the vehicle interior and helping to cool the vehicle when the outside 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 restrict heating/cool- ing capacity• Fan speed restricted when automatic
mode is selected
●To improve air conditioning perfor-
mance, perform the following opera- tions:• Adjust the fan speed
• Turn off Eco drive mode ( P.322)
●Even when the drive mode is set to
Eco drive mode, the air conditioning eco mode can be turned off by press-ing the “FAST/ECO” switch. ( P.344)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is
pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condition-
ing 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 occur-
ring: • It is recommended that the air condi-tioning 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.
●When parking, the system automati-cally switches to outside air mode to encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting the vehicle.
■nanoe™ X system (if equipped)*1, 2
This vehicle incorporates a biocidal product.
Ionised air generated by a device incor- porated in the vehicle purifies the air in the cabin by suppressing bacteria.
Active substance: Free radicals gener- ated in situ from ambient air or water.
nanoe™ helps to provide purified air by
emitting electrically charged water parti- cles through the front vent on the pas-senger side (left-hand drive vehicles) or
driver side (right-hand drive vehicles).*3
●When the fan is turned on and
nanoe™ X on the option control screen is selected, the nanoe™ X system is activated.
●When the fan is operated in the follow-ing conditions, system performance
will be maximized. If the following con- ditions are not met, performance will be limited.
• Air conditioner vent opening blows to the upper body, blows to the lower body and feet or feet.

• When opening the front vent on the
passenger side (left-hand drive vehi- cles) or driver side (right-hand drive vehicles).
●When nanoe™ X is generated, a small amount of ozone is emitted and
may be faintly smelled in some situa- tions. However, this is approximately the same as the amount that already
exists in nature, such as in forests, and it has no affect on the human body.
●A slight noise may be heard during operation. This is not a malfunction.*1: “nanoe X” is a “nanoe” generator.
*2: nanoe™ and the nanoe™ mark are
trademarks of Panasonic Corpora-
tion.
*3: According to temperature and humid-
ity conditions, fan speed and direc-
tion of the air flow, the nanoe™
system may not operate at full capac-
ity.

If the fan speed setting or air flow
modes are operated, the automatic
mode indicator goes off. However,
automatic mode for functions other
than that operated is maintained.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambient conditions.
WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather. The differ-ence 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.
■When the outside rear view mir-
ror defoggers are operating
Do not touch the outside rear view mirror surfaces, as they can become
very hot and burn you.
■nanoe™ X
Do not disassemble or repair the gen- erator because it contains high volt-
age parts. Contact any Toyota retailer or Toyota authorized repairer, or any repairer if the generator needs repair.
NOTICE
■To prevent 12-volt battery dis-charge
Do not leave the air conditioning sys-
tem on longer than necessary when the hybrid system is off.
■To prevent damage to the nanoe™ X
Do not insert anything into the front
center vent on the passenger side (left-hand drive vehicles) or driver side (right-hand drive vehicles) vent,
attach anything to it, or use sprays around the passenger side (left-hand drive vehicles) or driver side (right-
hand drive vehicles) vent. These things may cause the generator not to work properly.
