● 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 the outside/recir-

Outside/recirculated air mode
■
● When driving on dusty roads such as tun-
nels or in heavy traffic, set the outside/
recirculated air mode switch to the recir-
culated air mode. This is effective in pre-
venting outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirculated air mode will
also cool the vehicle interior effectively.
Outside/recirculated air mode may auto-
●
matically switch depending on the tem-
perature setting or the inside
temperature.
■ Registering air conditioning settings to
electronic keys (vehicles with driving
position memory)
● Unlocking the vehicle using an electronic
key and turning the engine switch to
IGNITION ON mode will recall that
key's registered air conditioning settings.
When the engine switch is turned off, the
●
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
● The system may not operate correctly if
more than one electronic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.

Ventilation and air conditioning odors
■
● To let fresh air in, set the air conditioning
system to the outside air mode.

emitted from the vents.
