for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally 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 the auto-
matic mode switch is pressed.
To turn on the “SYNC” mode,
perform any of the following pro-
cedures:
 Press the “SYNC” mode
switch.
 Adjust the front passenger’s
side temperature setting.
The indicator comes on when the
“SYNC” mode is on.
WARNING
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■To prevent burns
●Do not touch the rear view mir-
ror surfaces when the outside
rear view mirror defoggers are
on.
●Vehicles with windshield wiper
de-icer: Do not touch the glass
at lower part of the windshield
or to the side of the front pillars
when the windshield wiper de-
icer is on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the EV system is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your Toyota dealer.
When a part of the air conditioning
system, such as the evaporator, is
to be replaced, it must be
replaced with a new one.

This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. Unnecessary air
conditioning is suppressed, con-
tributing to increased electricity
consumption efficiency.
Front seat concentrated airflow
mode operates in the following
situations.
No passengers are detected
in the rear seats
 The windshield defogger is
not operating
While operating, illuminates.
■Manually turning front seat
concentrated airflow mode
on/off
In front seat concentrated air-
flow mode, directing airflow to
the front seats only and to all
seats can be switched via switch
operation. When the mode has
been switched manually, auto-
matic airflow control stops oper-
ating.
Press on the air conditioning
operation panel and switch the
airflow.
 Indicator illuminated: Airflow
to the front seats only
 Indicator off: Airflow to all the
seats
■Operation of automatic airflow
control
●In order to maintain a comfortable
interior, airflow may be directed to
seats without passengers immedi-
ately after the EV system is
started and at other times depend-
ing on the outside temperature.
●After the EV system is started, if
passengers move around inside
or enter/exit the vehicle, the sys-
tem cannot accura tely detect the
presence of passengers and auto-
matic airflow control will not oper-
ate.
■Operation of manual airflow
control
Even if the function is manually
switched to directing airflow to only
the front seats, w hen a rear seat is
occupied, it may automatically direct
airflow to all seats.
WARNING
■To not interrupt the wind-
shield defogger from operat-
ing
Do not place anything on the
instrument panel which may cover
the air outlets. Otherwise, air flow
may be obstructed, preventing the
windshield defoggers from defog-
ging.

the temperature settings of the air
conditioning system.
Press and hold “A/C” on the
wireless remote control to oper-
ate the Remote Air Conditioning
Remote Air Condition-
ing System
The Remote Air Condition-
ing System uses electrical
energy stored in the trac-
tion battery and allows the
air conditioning to be oper-
ated by remote control.
If the Remote Air Condition-
ing System is used while
the charging cable is con-
nected to the vehicle, the
reduction of charge in the
traction battery will be sup-
pressed to allow you to use
electricity from an external
power source.
Charging will be conducted
automatically after the
Remote Air Conditioning Sys-
tem is stopped.

■Operating conditions
The system will only operate if all of
the following cond itions are met:
●The power switch is OFF.
●All doors are closed.
●The hood is closed.
■Remote Air Conditioning Sys-
tem automatic shut-off
The system will auto matically shut
off under the following conditions:
●About 20 minutes have passed
since operation began
●Any one of the operating condi-
tions is not met
The system may also shut off if the
charge level of the traction battery drops to low.
■Conditions affecting operation
The system may not start in the fol-
lowing situations:
●The charge level of the traction
battery is low
●When the EV 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 insuffi-
cient 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 outsi de temperature,
humidity or air conditioning set tem-
perature.
■Security feature
Any unlocked doors will be automat-
ically locked when the system is
operating. The emergency flashers
flash to indicate that the doors have
been locked.
■Conditions affecting operation
 P.188
■While the Remote Air Condi-
tioning System is operating
●Depending on the operating con-
dition of the Remote Air Condition-
ing System, the e lectric fan may
spin and an operating noise may
be heard.
However, this does not indicate a
malfunction.
●The Remote Air Conditioning Sys-
tem may stop operating temporar-
ily if other features that use
electricity (for example, the seat
heater, lights, windshield wipers)
are in operation or if the charge
level of the 12-volt battery
becomes low.
●The headlights, windshield wiper,
meter, etc. will not operate.

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 dehydration or
hypothermia, or could result in
death or serious injury.
●Depending on the surrounding
environment, signals from the
wireless switch may transmit
further than expected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when necessary.
●Do not operate “A/C” if the hood
is open. The air conditioning
may operate unintentionally and
objects may be drawn into the
electrical cooling fan.

Maintenance and care
 Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
■Front side window s with IR pro-
tective coating
The front side windows have IR pro-
tective coating. To prevent any dam-

• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of
the vehicle usin g a high pres-
sure car washer. If water enters
the traction battery, the EV sys-
tem may malfunction.
●Do not use the washer on the
area around the charging port
lid. Water could get into the
charging inlet and could dam-
age the vehicle.
■Cleaning aluminum parts
When cleaning the hood, do not
push hard or put weight on it.
The aluminum part may be
dented.
