settings will be set to those that were in use the last time the “ENGINE START
STOP” switch was turned off.
Air conditioning system settings are memorized individually on each electronic key,
so the settings reproduced will be specific to the key that is used.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent conditions. As a result, the following may occur.
●Immediately after the switch is pressed, the fan may stop for a while until warm
or cool air is ready to flow.

Recirculated air mode or outside air mode may be automatically switched to in
accordance with the temperature setting, the inside temperature, outside tempera-
ture, etc.
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used.
■Window defogger feature
Recirculated air mode may automatically switch to
(outside air) mode in situ-
ations where the windows need to be defogged.
■Automatic mode for air intake control (vehicles with a rear automatic air condi-
tioning system)

matically switches between outside air and recirculated air modes.
When the air conditioning is off, and the fan is operating, turning automatic mode
on will activate the air conditioning system.

■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.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in AUTO mode.
■Customization
Settings (e.g. enable/disable automatic operation of the air conditioning compres-
sor when the “AUTO” switch ON) can be changed.
(Customizable features →P. 7 8 2 )
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference 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.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is stopped.
