WARNING
■Caution regarding the use of
windshield wipers in “AUTO”
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in “AUTO” mode.
Take care that y our fingers or
anything else does not become
caught in the windshield wipers.
■Caution regarding the use of
washer fluid
When it is cold, do not use the
washer fluid until the windshield
becomes warm. The fluid may
freeze on the windshield and
cause low visibility. This may lead
to an accident, resulting in death
or serious injury.
NOTICE

empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.
■When a nozzle becomes
blocked
In this case, conta ct your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.
■To prevent 12-volt battery dis-
charge
Do not leave the wipers on longer
than necessary when the hybrid
system is off.

3444-6. 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, vehicle’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.

Park the vehicle and move
the shift lever 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 dan-
gerous 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 lever to P. ( P.243)
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.
 If the vehicle is parked without
setting the parking brake,
confirm that the shift lever
cannot be moved out of P
*.
*: The shift lever will be locked if it is
attempted to be shifted from P to
any other position without
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.

■Defogging the rear window
and outside rear view mir-
rors (if equipped), and de-
icing windshield wipers (if
equipped)
Defoggers are used to defog the

■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.
■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 c ool 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
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
consumption.
●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/recirculated air mode

Interior features
stable power supply
●Devices that require a constant
power supply from the power out-
let, such as a device with a timer.
■When the 120 VAC power out-
lets cannot be used
If the AC120V switch is pressed but
the switch indicator does not illumi-
nate, the protection circuit may have
operated.
In this case, perform the appropriate
procedures as follows.
●Disconnect the plug of each
device from the p ower outlets,
check that the total power con-
sumption of all devices to be con-
nected to the power outlets is less
than 1500 W and check that the
devices are not malfunctioning,
reconnect the devices and then
press the AC120V switch again.
●Check the charge of the hybrid
battery (traction battery)
(  P.122). If the charge is low,
shift the shift lever to P, allow the
engine to run to charge the hybrid
battery (traction battery), and then
press the AC120V switch again.
●If the temperature inside the vehi-
cle is high, such as after the vehi-
cle has been park ed in the sun,
use the air conditioning system to
sufficiently ventilate or cool the
interior, and then press the
AC120V switch again.
●If the vehicle has been stopped in
a cold area, to pro tect the hybrid
battery (traction battery), the
power outlets may not be able to
be used. In this case, drive the
vehicle for a while to warm up the
hybrid battery (traction battery),
and then press the AC120V
switch again.
If the power outlets cannot be used
even after performing the appropri-
ate procedures above, have the
vehicle inspected by your Toyota
dealer.
WARNING
■For safe use
Observe the following precau-
tions.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Do not use devices such as the
following when driving:
• Devices which cannot be prop- erly secured within the vehicle.
• Devices which may distract the driver and be a hinderance to
safe driving, such as a TV, DVD
player, etc.
• Unsecured devices which gen- erate heat, such as a toaster,
microwave, electric heater,
electric kettle, coffee maker,
etc., as they may cause burns
or a fire in the case of sudden
braking or an accident.
• Devices which may fall under the pedals and prevent the
brake pedal from being
depressed.
●Do not use devices which pro-
duce steam while the windows
are closed. Doing so may cause
the windows to fog up, reducing
visibility and making it difficult to
drive safely. Also, the steam
may damage or negatively
affect other devices.
●Do not connect a malfunctioning
device to a power outlet, as
doing so may cause the power
outlets to become inoperable.
●Do not disconnect the plug of a
device while your hands are wet
or insert a pin or other object
into the power ou tlet. Also, if a
liquid or snow is on the power
outlet, dry the outlet before
using it.
