(road surface freeze prevention
heater)
• When the wheels are mis- aligned, such a fter a wheel has
been subjected to a strong
impact
• When a pedestrian or passing vehicle is detected during assis-
tance
• When something is incorrectly detected as a parking line (light,
reflections from a building, dif-
ference in height on the parking
surface, a gutter, painted road
lines, redrawn lines, etc.)
If the vehicle deviates greatly from
the set parking space in any situa-

4366-1. Using the air conditioning system and defogger
switch.
■Defogging the rear window
(if equipped)
A defogger is used to defog the
rear window.
Press the rear window defogger
switch.
When the rear window defogger
switch is on, the indicator illumi-
nates on the rear window defogger
switch.
The defogger will automatically turn
off after 15 minutes.
■Defogging the rear window
and outside rear view mir-
rors (if equipped)
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 and out-
side rear view mirror defoggers
switch.
When the rear window and outside
rear view mirror defoggers switch is
on, the indicator illuminates on the
rear window and outside rear view
mirror defoggers switch.
The defoggers will automatically
turn off after 15 minutes.
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally.
This may also reduce fuel con-
sumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
●It is possible to switch to outside
air mode at any time by pressing
the outside air mode 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.
• 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.
Outside heat exchanger
●In the following situations the gas-
oline engine may operate in order
to extract heat from the engine
coolant via the heater even in EV
mode.
• The outside temperature is approximately 75°F (24°C) or low
• Windshield defogger is operating

1Press the “AUTO” switch.
2 Adjust the temperature set-
ting.
3 To stop the operation, press
the “OFF” switch.
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 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.
Cool air may blow around the upper
body even when the heater is on
due to sunlight.
■Windshield fog detection func-
tion
When automatic mode is set, the
humidity sensor detects fog on the
windshield and controls the air con-
ditioning system to prevent fog.
WARNING
■Cautions for using “My Room
Mode”
Do not leave children, people who
need assistance, or pets inside
the vehicle. The system may turn
off automatically and the interior
temperature may become high or
low, resulting in heat stroke, dehy-
dration or hypothermia. Failure to
do so may result in death or seri-
ous injury.
■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.
■When the outside rear view
mirror defoggers are operat-
ing (if equipped)
Do not touch the rear view mirror
surfaces when the outside rear
view mirror defoggers are on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the hybrid 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 condition-
ing system, such as the evapora-
tor, is to be replaced, it must be
replaced with a new one.
Using automatic mode
NOTICE
■Humidity sensor
In order to detect fog on the wind-
shield, a sensor which monitors
the temperature of the windshield,
the surround humidity, etc. is
installed.
Follow these points to avoid dam-
aging the sensor:
●Do not disassemble the sensor
