3886-1. Using the air conditioning system and defogger
COROLLA_Uswitch.
■Defogging the rear window
and outside rear view mir-
rors
Vehicles without outside rear
view mirror defoggers
A defogger is used to defog the
rear window.
Press the rear window defogger
switch.
The defogger will automatically turn
off after a while.
When the rear window defogger
switch is on, the indicator illumi-
nates on the rear window defogger
switch.
Vehicles with outside rear
view mirror defoggers
Defoggers are used to defog the
rear window, and to remove
raindrops, dew and frost from
the outside rear view mirrors.
Press the rear window and out-
side rear view mirror defoggers
switch.
The defoggers will automatically
turn off after a while.
When the rear window and outside
rear view mirror defoggers switch is
on, the indicator illuminates on the
rear window and outside rear view
mirror defoggers switch.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” switch is on
will dehumidify the air from the
outlets and defog the windshield
effectively.
●If you turn “A/C” switch is 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
outside/recirculated air mode switch
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
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning 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.
●It is recommended that the air
conditioning system be set to out-
side air mode prior to turning the
vehicle off.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.

WARNING
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■When the outside rear view
mirror defoggers are operat-
ing
Do not touch the outside rear view
mirror surfaces, as they can
become very hot and burn you.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning
system on longer than necessary
when the engine is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your Toyota dealer.
When a part of the air conditioning
system, such as the evaporator, is
to be replaced, it must be
replaced with a new one.
