■Heating
●In HV mode, the gasoline engine may operate in order to exhaust 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 con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor- mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing ( →P. 509). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. Therefore, the set heating performance may not be achieved even if the fan speed
setting is increased.
● In the following situations the gasoline engine may operate in order to
exhaust heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately -10 °C or low
• is operating
■ 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.
■ Water droplets during air conditioning operation• 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.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.

■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The buzzer sounds and the emergency flashers flash to indicate that the
doors have been locked or the system has been turned off.

■ Conditions affecting operation
→P. 281
■ When using the Remote Air Conditioning System
A charging message will be displayed on the multi-information display. Differ-
ent messages will be displayed depending on when the Remote Air Condi-
tioning System was started (after charging or during charging).
■ While the Remote Air Conditioning System is operating
●Depending on the operating condition of the Remote Air Conditioning Sys-
tem, the electric fan may spin and an operating noise may be heard. How-
ever, this does not indicate a malfunction.
● The Remote Air Conditioning System may stop operating temporarily if
other features that use electricity (for example, the seat heater, lights, wind-
shield wipers) are in operation or if the charge level of the 12-volt battery
becomes low.
● The headlights, windshield wiper, combination meter, etc. will not operate
while the Remote Air Conditioning System is operating.
■ Electronic key battery depletion
→P. 264
■ When the electronic key battery is fully depleted
→P. 627
■ Customization
Setting (e.g. Operation using “A/C” on the wireless remote control) can be
changed. (Customizable features →P. 732)
■ Smartphone-linked op eration (vehicles with 11.6-inch display)
After applying to Entune, it is possible to use the smartphone application to

Interior features
■The wireless charger can be operated when
The power switch is in ACCESSORY or ON mode.
■ Usable portable devices
Qi standard wireless charge standard can be used on compatible devices.
However, not all Qi standard devices and compatibility are guaranteed.
Starting with mobile phones and smart phones , it is aimed for low power elec-
trically supplied portable devices of no more than 5W.
■ When covers and accessories are attached to portable devices
Do not charge in situations where cover and accessories not able to handle
Qi are attached to the portable device. Depending on the type of cover and
accessory, it may not be possible to charge. When charging is not performed
even with the portable device placed on the charge area, remove the cover
and accessories.
■ While charging, noise enters the AM radio
Turn off the wireless charger and confirm that the noise has decreased. If the
noise decreases, continuously pushing the power supply switch of the wire-
less charger for 2 seconds, the frequency of the charger can be changed and
the noise can be reduced.
Also, on that occasion, the operation indicator light will flash orange 2 times.
■ Important points of the wireless charger
●If the electronic key cannot be detected within the vehicle interior, charging
cannot be done. When the door is opened and closed, charging may be
temporarily suspended.
● When charging, the wireless charging device and portable device will get
warmer, however this is not a malfunction.
When a portable device gets warm while charging, charging may stop due
to the protection function on the portable device side. In this case, when the
temperature of the portable device drops significantly, charge again.
■ Operation sounds
When the power supply is turned on, while searching for the portable device a
sound will be produced, however this is not a malfunction.
