3986-1. Using the air conditioning system and defogger
tized such as reducing fan
speed, etc.
Press the eco air conditioning
mode switch.
When the eco air conditioning
mode is on, the indicator illumi-
nates on the eco air conditioning
mode switch.
■Defogging the windshield
Defoggers are used to defog the
windshield and front side win-
dows.
Press the windshield defogger
switch.
Set the outside/recirculated air
mode switch to outside air mode if
t h e r e c i r c u l a t e d a i r m o d e i s u s e d . ( I t
may switch automatically.)
To defog the windshield and the
side windows quickly, turn the air
flow and temperature up.
To return to the previous mode,
press the windshield defogger
switch again when the windshield is
defogged.
When the windshield defogger
switch is on, the indicator illumi-
nates on the windshield defogger
switch.
■Defogging the rear window
and outside rear view mir-
rors
Defoggers are used to defog the
rear window and to remove rain-
drops, dew and frost from the
outside rear view mirrors.
Press the rear window defogger
and outside rear view mirror
defoggers switch.
The defoggers will automatically
turn off after 15 minutes.
When the rear window defogger
and outside rear view mirror defog-
gers switch is on, the indicator illu-
minates on the rear window
defogger and outside rear view mir-
ror defoggers switch.
■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
conventional 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 interior.
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 per-
formance will decline. The frost
can be removed from the outside
heat exchanger by operating the
Remote Air Conditioning System
before driving ( P.405). When
frosted over, the heating operation
of the Remote Air Conditioning
System starts after defrosting.
• When “AUTO” switch is turned on,
the heating is controlled opti-
mally. Therefore, the set heating
performance may not be achieved
even if the fan speed setting is
increased.

Interior features
If the Remote Air Conditioning
System is used while the AC
charging cable is connected to
the vehicle, electricity from an
external power source can be
used minimizing the drop in
charge of the hybrid battery
(traction battery).
Charging will be conducted auto-
matically after the Remote Air Con-
ditioning System is stopped.
Check the temperature setting
of the air conditioning system.
( P.396)
The Remote Air C onditioning Sys-
tem will operate in accordance with
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
System.
The system can be stopped by
pressing “A/C” twice.
■Operating conditions
The system will only o perate if all of
the following conditions are met:
●The shift lever is in P.
●The power switch is off.
●All doors are closed.

■Remote Air Conditioning Sys-
tem automatic shut-off
The system will automatically shut
off under the follo wing 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 hybrid battery
(traction battery) drops to low.
■Conditions affecting operation
The system may not start in the fol-
lowing situations:
●The charge level of the hybrid bat-
tery (traction battery) is low
●The outside temperature is
extremely low
●When the hybrid system is cool
(for example , after being left for a
long time in low temperatures)
■Windshield defogger

4667-3. Do-it-yourself maintenance
The 12-volt battery is located in
the right-hand side of luggage
compartment.
■Before recharging
When recharging, the 12-volt bat-
tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the power switch on
the charger is off when connecting
and disconnecting the charger
cables to the 12-volt battery.
■After recharging/reconnecting
the 12-volt battery
●The hybrid system may not start.
Follow the procedure below to ini-
tialize the system.
1 Shift the shift lever to P.
2 Open and close any of the doors.
3 Restart the hybrid system.
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the
power switch in
ACC. The hybrid
system may not start with the
power switch turned off. How-
ever, the hybrid system will oper-
ate normally from the second
attempt.
●The power switch mode is
recorded by the vehicle. If the 12-
volt battery is reconnected, the
vehicle will return the power
switch mode to the status it was in
before the 1 2-volt battery was dis-
connected. Make sure to turn off
the power switch before discon-
nect the 12-volt battery. Take
extra care when connecting the
12-volt battery if the power switch
mode prior to discharge is
unknown.
If the hybrid sys tem will not start
even after multiple attempts at all
methods above, contact your
Toyota dealer.

If communication between
the electronic key and vehi-
cle is interrupted ( P.218)
or the electronic key cannot
be used because the battery
is depleted, the smart key
system and wireless remote
control cannot be used. In
such cases, the doors can

5418-2. Steps to take in an emergency
8
When trouble arises
recharge the 12-volt battery
of your vehicle.
6 Open and close any of the
doors of your vehicle with the
power switch off.
7 Maintain the engine speed of
the second vehicle and start
the hybrid system of your
vehicle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the exclusive jump
starting terminal cover, and
reinstall the fuse box cover to
its original position.
Once the hybrid system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the hybrid system
when the 12-volt battery is dis-
charged
The hybrid system cannot be
started by push-starting.
■To prevent 12-vol t battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnec essary electri-
cal components when the vehicle is running at a low speed for an
extended period, such as in heavy
traffic.
■When the 12-volt battery is
removed or discharged
●Information stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at you
r Toyota dealer.
●Some systems may require initial-
ization. (P.582)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-vo lt battery termi-
nals, contact your Toyota dealer.
■Charging the 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the hybrid system may
be unable to start. (The 12-volt bat-
tery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the 12-
volt battery is discharged. Use the
wireless remote c ontrol or the
mechanical key to lock or unlock
the doors.
●The hybrid syste m may not start
on the first attemp t after reinstall-
ing the 12-volt battery. In that
case, start the hybrid system in
the same manner as when the
electronic key does not operate
properly ( P.538). This is not a
malfunction, as the hybrid system
will start normally on the second
attempt.
