■Operation of the air conditioning system in Eco drive mode (if equipped)
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
●Engine speed controlled to restrict heating/cooling capacity.
●Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
●Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
●Adjust the fan speed.
●Turn off Eco drive mode. (→P. 184)

Interior features
COROLLA_TMMMS_TMMC_U (OM02494U)■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 button to 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 or the inside temperature.

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 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.

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 rear view mirror
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. (if equipped)
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.
