4305-6. Driving tips
Perform the following according
to the driving conditions:
Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, outside rear
view mirrors, windows, vehi-
cle’s roof, chassis, around the
tires or on the brakes.
 Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle. Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.

Turn automatic mode of the
parking brake off.
Otherwise, the parking brake
may freeze and not be able to
be released automatically.
Also, avoid using the following as
the parking brake may operate
automatically, even if automatic
mode is off.
• Brake hold system
Park the vehicle and shift the
shift position to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels. Failure to
do so may be dangerous
because it may cause the
vehicle to move unexpect-
edly, possibly leading to an
accident.
 When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift position to P.
( P.264)
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from your Toyota
dealer or legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.

■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

Interior features
■Water droplets during air condi-
tioning operation
The outside heat exchanger, accu-
mulator 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. Ho wever, it is not a
malfunction.

Outside heat exchanger
■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
dehumidify the air from the outlets
and defog the windshield effec-
tively.
●If you turn “A/C” switch off, the
windows may fog up more easily.
●The windows may fog up if the
recirculated air mode is used.
■While using “My Room Mode”
●It may not be possible to obtain
the intended defogging perfor-
mance even if the windshield
defogger switch is pressed. If the
windows need to be defogged
before driving, stop charging
power and then press the wind-
shield defogger switch.
●When the outside temperature is
low, heating may feel insufficient
due to restricted operation of the
air conditioning.
Heating cannot be performed
when it is approximately 14°F (-
10°C) 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 vehicle.
■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 recommended 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 recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to cool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is pressed.
■Operation of the air condition-
ing system in the eco air condi-
tioning mode
●In the eco air conditioning mode,
the air conditioning system is con-
trolled as follows to prioritize fuel
efficiency:
• Engine speed and compressor
operation controlled to restrict
heating/cooling capacity
• Fan speed restricted when auto-
matic mode is selected
●The eco air conditioning mode can
be turned on and off using the
option screen of the air condition-
ing control screen. ( P.440)
●When the driving mode is
changed to Eco drive mode, the
eco air conditioning mode is
