Adjusting the settings
To adjust the fan speed, turn the fan speed control dial clock-
wise (increase) or counterclockwise (decrease).
Turning the dial to turns off the fan.
Vehicles without a cooling and dehumidification function on/off
button:
Turn the temperature control lever up to increase the tem-
perature.
Vehicles with a cooling and dehumidification function on/off
button:
To adjust the temperature setting, turn the temperature control
lever up (warm) or down (cool).
If is not pressed, the system will blow ambient tem-
perature air or heated air.
To select the air outlets, set the air outlet selection lever 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 lever to
position.
Vehicles with an outside/recircu-
lated air mode lever: Set the out-
side/recirculated air mode lever to
outside mode if recirculated air
mode is used.

Adjusting the position of and opening and closing the air outlets
Direct air flow to the left or right,
up or down.
Open the vent.
Close the vent.
Fogging up of the windows (vehicles with a cooling and dehumidifica-
tion function on/off button)
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.

Fogging up of the front side door windows
Outside/recirculated air mode (vehicles with an outside/recirculated air
mode lever)
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode lever to the recirculated air mode. This is effective
in preventing outside air from entering the vehicle interior. During cooling
operation, setting the recirculated air mode will also cool the vehicle interior
effectively.
When the indicator light on goes off by itself (vehicles
with a cooling and dehumidification function 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 any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
When the outside temperature falls to nearly 0°C (32°F) (vehicles with a
cooling and dehumidification function on/off button)
The dehumidification function may not operate even when is
pressed.
The front side door windows can be
quickly defogged by turning the side
vents to the windows.

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 (vehicles with a cooling and dehumidification
function on/off button)
P. 279
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.

Maintenance and care
AYGO_WE_99E96E
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. 266)
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.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Minimum temperature: -35C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
CAUTION
When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
