5-1. Using the air conditioning system and defogger
●
Adjust the temperature setting
●
Turn off Eco drive mode (P.257)
■
Fogging up of the windows
●
The windows will easily fog up when
the humidity in the vehicle is high.
Turning the "A/C" switch on will dehu-
midify the air from the outlets and
defog the windshield effectively.
●
If you turn the "A/C" switch off, the
windows may fog up more easily.
●
The windows may fog up if the recir-
culated 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 switch to the
recirculated air mode. This is effective in
preventing outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirculated air mode
will also cool the vehicle interior effec-
tively.
■
When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not
operate even when the "A/C" switch is
pressed.
■
Ventilation and air conditioning
odors
●
To let fresh air in, set the air condition-
ing 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 occur-
ring:
It is recommended that the air condi-
tioning system be set to outside air
mode prior to turning the vehicle off.
●
When parking, the system automati-
cally switches to outside air mode to
encourage better air circulation
throughout the vehicle, helping to
reduce odors that occur when starting
the vehicle.
■
Air conditioning system opera-
tions when the engine is stopped
due to the Stop & Start system
(vehicles with Stop & Start system)
When the engine is stopped due to the
Stop & Start system operations, the air
conditioning cooling, heating and dehu-
midification functions turn off and only
ambient temperature air is blown, and
there is a possibility that the blowing of
ambient temperature air will stop. To
prevent the air conditioning system from
turning off, press the Stop & Start cancel
switch to deactivate the system.
■
When the windshield is fogged up
and the engine is stopped due to
the Stop & Start system (vehicles
with Stop & Start system)
Press the windshield defogger switch to
restart the engine and defog the wind-
shield.
If the windshield continuously fogs up,
press the Stop & Start cancel switch and
refrain from using the Stop & Start sys-
tem.
■
When an odor comes from the air
conditioning system while the
engine is stopped due to the Stop &
Start system (vehicles with Stop &
Start system)

WARNING
■
To prevent the windshield from
fogging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The differ-
ence between the temperature of the
outside air and that of the windshield
can cause the outer surface of the
windshield to fog up, blocking your
vision.
