■Using automatic mode
Fan speed is adjusted automatically 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 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 wind-
shield effectively.
●If you turn off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
●Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant temper-
ature or inside temperature.
Rear outlets
Direct air flow to the left or right, up or down.
Turn the knob to open or close the vent.

4RUNNER (U)_(OM35B23U)■When the outside temperature exceeds 75°F (24°C) and the air condition-
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 engine switch
is turned to the “ON” position (vehicles without a smart key system) or the
engine switch is turned to IGNITION ON mode (vehicles with a smart key
system).
●It is possible to switch to outside air mode at any time by pressing
.
■When the outside temperature falls to nearly 32F (0C)
The dehumidification function may not operate even when is pressed.
■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 intake mode be
set to outside air mode and the fan speed to any setting except off.
■When the indicator light on flashes
Press
to turn off the cooling and dehumidification function and turn it on
again. There may be a problem in the air conditioning system if the indicator
light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
■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 cause odor to
be emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.

CAUTION
■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 rear view mir-
ror defoggers are on.
●Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary 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
from defogging.

Seat heaters/seat ventilators
: If equipped
The seat heaters warm the seats and the seat ventilators main-
tain good airflow by blowing air through the seats.

• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
●Observe the following precautions to prevent the minor burns or overheat-
ing
• Do not cover the seat with a blanket or cushion when using the seat
heater.
• Do not use seat heater more than necessary.
NOTICE
●Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
●To prevent battery discharge, do not use the functions when the engine is
off.

■The power outlet can be used when
The engine is running.
■The indicator light changes according to the maximum available capac-
ity as follows:
■When the power outlet is in operation
The sound of the cooling fan may be heard from the right side of the luggage
compartment. This is normal and does not indicate a malfunction.
■If the engine is started with the power outlet main switch on
The maximum capacity of the power supply may decrease to below the stan-
dard, or may be cut off completely, even when the vehicle is stationary.
■The protection circuit may be activated to cut the power supply if any of
the following conditions apply:
●The engine is started with the power outlet main switch on.
●Use of electrical appliances exceeding the maximum capacity is attempted.
A sound may be heard when the protection circuit is activated. This is nor-
mal and does not indicate a malfunction.
●Electrical appliances, which consume power exceeding 100 W, have been
used continuously for a long time period.
●The total power usage by all electrical features (headlights, air conditioning,
etc.) has exceeded the total vehicle maximum for an extended period of
time.120 V AC/400 W

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 operate 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 that 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 trim, 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 of the sun while
parking, may result in damage to those electrical appliances.
