Adjusting the settings
To adjust the fan speed, turn the fan speed control dial clock-
wise (increase) or count erclockwise (decrease).
Turning the dial to “0” turns off the fan.
Vehicles without an air conditioning on/off button:
Turn the temperature control di al clockwise to increase the
temperature.
Vehicles with an air conditioning on/off button:
To adjust the temperature setting, turn the temperature control
dial clockwise (warm) or counterclockwise (cool).
If is not pressed, the system will blow ambient temperature
air or heated air.
For quick cooling, turn the temperature control dial to “
MAX A/C”
position and set the outside/recirculated air mode button to recircu-
lated air mode.
To select the air outlets, set the air outlet selector dial to the
desired position.
The positions between the air outlet selections shown below can
also be selected for more delicate adjustment.
Defogging the windshield
Set the air outlet selector dial to position.
If the recirculated air mode is
used, it will automatically switch
to the outside air mode.
In this position, the outside/recir-
culated air mode cannot be
changed to the recirculated air
mode.

Air flows mainly to the feet.
: Some models
Air flows to the feet and the
windshield defogger operates.
If the recirculated air mode is
used, it will automatically switch
to the outside air mode.
In this position, the outside/recir-
culated air mode cannot be
changed to the recirculated air
mode.
Switching between outside air and recirculated air modes
Press .
The mode switches between outside air mode (introduces air from
outside the vehicle) (indicator off) and recirculated air mode (recy-
cles air inside the vehicle) (indicator on) each time the button is
pressed.
: Some models

Interior features
■Fogging up of the windows
●The windows will easily fog up when the humidify in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively. (vehicles with an air conditioning on/off button)
● If you turn off, the windows may fog up more easily. (vehicles with
an air conditioning on/off button)
● 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 button to the recirculated air mode. This is effec-
tive in preventing outside air from enter ing the vehicle interior. During cooling
operation, setting the recirculated air m ode will also cool the vehicle interior
effectively.
■ When the indicator light on goes off by itself (vehicles with an
air conditioning on/off button)
Press to turn off the dehumidification function and turn it on again.
There may be a problem in the air conditioning system if the indicator light
goes off again. Turn the air conditioning system off and have it inspected by
your Toyota dealer.
■ When the outside temperature falls to nearly 32°F (0°C) (vehicles with
an air conditioning on/off button)
The dehumidification function may not operate even when
is
pressed.

■Air conditioning odors
●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.
■ Air conditioning filter
→ P. 268
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 wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

Interior features
Rear window and outside rear view mirror defoggers∗
∗: If equipped
■The defoggers can be operated when
The engine switch is in the “ON” position.
■ The outside rear view mirr or defoggers (if equipped)
Turning the rear window defogger on will turn the outside rear view mirror
defoggers on.
CAUTION
■ When the outside rear view mirr or defoggers are on (if equipped)
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
Defoggers are used to defog the rear window, and to remove rain-
drops, dew and frost from the outsid e rear view mirrors (if equipped).
Turn the defoggers on/off
The defoggers will automati-
cally turn off after approxi-
mately 15 minutes.

Maintenance and care
CAUTION
■
When working near the electric cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the electric cooling fan may automatically start to
run if the air conditioning is on and/or the coolant temperature is high.
( → P. 247)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also, a backfire could cause a fire in the engine com-
partment.

260 4-3. Do-it-yourself maintenance
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure warn-
ing system)
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not handled
correctly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmit-
ters (vehicles with a tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( →P. 254)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition, driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
■Low profile tires (vehicle s with P195/50R16 tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention
to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

264 4-3. Do-it-yourself maintenance
CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions
may occur and result in an accident causing death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resu lting from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or mo isture could get into the valve and
cause air leakage, which could result in an accident. If the caps are lost,
replace them as soon as possible.
