Interior features
■Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn 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 vehi-
cle after closing the windows, it is recommended that the air i ntake 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 recommended in prevent-
ing 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 dependin g on the
temperature setting or the inside temperature.
■ When the outside temperature exceeds 75°F (24°C) and the air co ndition-
ing system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the en gine switch
is in the “ON” position (vehicles without a smart key system) o r IGNITION
ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pre ssing .
■ When the outside tempera ture falls to nearly 32F (0 C)
The dehumidification function may not operate even when is selected.

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in automatic
mode.

WARNING
■To prevent the windshield from fogging up
● Do not use
during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rea r view mirror
defoggers are on.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning system on longer than necessa ry when the
engine is stopped.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers to
defog.

NOTICE
■To avoid damaging the power outlet and the plug
● Close the power outlet lid when not in use.
● Do not allow foreign objects or liquids to enter the power outlet, as this
may cause a short circuit.
● Do not use plug adaptors to connect too many plugs to the power outlet.
● After removing a plug, gently close the power outlet lid.
■ To prevent the fuse from being blown
Do not use a 120 V AC appliance that requires more than the maximum
capacity of the power outlet. If a 120 V AC appliance that consumes more
than the maximum capacity is used, the protection circuit will cut the power
supply.
■ Appliances that may not op erate properly (120 V AC)
The following 120 V AC appliances may not operate even if their power con-
sumption is under maximum capacity.
● Appliances with high initial peak wattage
● Measuring devices that process precise data.
● Other appliances that require an extremely stable power supply
■ To prevent battery discharge
Turn off all the vehicle’s electronic equipment and accessories, such as the
headlights and air conditioning, when electrical appliances tha t consume in
excess of 100 W are used continuously for long periods of time.
■ To prevent any damage caused by heat
● Do not use any electrical appliances that give off intense heat, such as
toasters, in any locations including the internal or external t rim, seats and
deck.
● Do not use any electrical appliances that are easily affected by vibration or
heat inside the vehicle. Vibration while driving, or the heat o f the sun while
parking, may result in damage to those electrical appliances.
■ If any electrical appliances are to be used while driving
Securely fasten both the appliances and their cables to prevent them from
falling or getting caught in any of the power train components.
■ If the power outlet is loose when an electrical appliance plug is con-
nected
Replace the outlet. Contact your Toyota dealer for any necessary replace-
ments.
