■For quick cooling (vehicles with an air conditioning system)
Turn the dial to the “MAX A/C” position and select the recirculated air
mode.
■ Fogging up of the windows
●Vehicles with the 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.
● Vehicles with the button: 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 button 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 outside temperature is low (vehicles with the button)
The air conditioning system may not operate even when
is pressed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air m\
ode.
● 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.

3806-1. Using the air conditioning system and defogger
COROLLA_TMMMS_TMMC_U (01999-02509)■
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.
Vehicles without a smart key system
● Recirculated air mode is selected as a default mode when the engine switch
is turned to the “ON” position.
Vehicles with a smart key system
● Recirculated air mode is selected as a default mode when the engine switch
is turned to IGNITION ON mode.
● It is possible to switch to outside air mode at any time by pressing .
■ When the outside temperature is low
The dehumidification function may not operate even when is pressed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air m\
ode.
● 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.
