the ABS, brake assist, VSC, Trailer
Sway Control, TRC and hill-start
assist control systems
●A sound may be heard from the
engine compartment when the brake
pedal is depressed repeatedly, when
the hybrid system is started or just
after the vehicle begins to move. This
sound does not indicate that a mal-
function has occurred in any of these
systems.
●Any of the following conditions may
occur when the above systems are
operating. None of these indicates
that a malfunction has occurred.
• Vibrations may be felt through the
vehicle body and steering.
• A motor sound may be heard also
after the vehicle comes to a stop.

■Heating
●In HV mode, the gasoline engine may
operate in order to extract heat from
the engine coolant via the heater.
●In EV mode, heating is done by a heat
pump system.
• When the outside temperature is low
or it is snowing, compared to conven-
tional vehicles, heating may be less
effective and warm air may not come
out.
• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
• If frost has formed of the outside heat
exchanger, the heating performance
will decline. The frost can be removed
from the outside heat exchanger by
operating the Remote Air Conditioning
System before driving (P.438).
When frosted over, the heating opera-
tion of the Remote Air Conditioning
System starts after defrosting.
• When “AUTO” switch is turned on, the
heating is controlled optimally. There-
fore, the set heating performance may
not be achieved even if the fan speed
setting is increased.
Outside heat exchanger
●In the following situations the gasoline
engine may operate in order to extract
heat from the engine coolant via the
heater even in EV mode.
• The outside temperature is approxi-
mately -10°C (14°F) or low

■Water droplets during air condi-
tioning operation
The outside heat exchanger, accumula-
tor and air conditioning piping may incur
condensation or frost may form. During
or after the air conditioning operation,
water droplets may fall from the vehicle.
However, it is not a malfunction.

■Fogging up of the windows
●The windows will easily fog up when
the humidity in the vehicle is high.
Turning “A/C” switch 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 power and then press
.
●When the outside temperature 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 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:
• Turn off Eco drive mode (P.411)
• Turn off blower customization
(P.432)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not
operate even when “A/C” switch is
pressed.

low
●When the hybrid system is cool (for
example, after being left for a long time in low temperatures)
■Windshield defogger
When defogging the windshield using
the Remote Air Conditioning System, defogging may be insufficient due to the power being restricted more than during
normal air conditioning operation. Also, the outside of the windshield may fog up due to the outside temperature, humidity
or air conditioning set temperature.
■Using the heater via the Remote Air Conditioning System
●When the outside temperature is low, heating may feel insufficient due to restricted operation of the air condi-
tioning.
●When the outside heat exchanger
becomes frosted over, heating perfor- mance may decline due to automati-cally switching to the frost removal
operation. ( P.432)
■Security feature
Any unlocked doors will be automatically locked when the system is operating.
The emergency flashers flash to indicate that the doors have been locked or the system has been turned off.
■Conditions affecting operation

WARNING
■Precautions for the Remote Air Conditioning System
●Do not use the system if people are in the vehicle. Even when the system is in use, the
internal temperature may still reach a high or low level due to features such as the automatic shut-off.
Children and pets left inside the vehicle may suffer heatstroke dehy-dration or hypothermia, or could
result in death or serious injury.
●Depending on the surrounding envi-
ronment, signals from the wireless switch may transmit further than expected. Pay appropriate attention
to the vehicle’s surroundings and use the switch only when neces-sary.
●Do not operate “A/C” on the wire-less remote control if the hood is
open. The air conditioning may operate unintentionally and objects may be drawn into the electrical
