Outside/recirculated air mode
●
When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior. Dur-
ing cooling operation, 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.

may also reduce fuel consumption.

Recirculated air mode is selected as a default mode when the engine
switch is turned to the "ON" position (vehicles without a smart key sys-
tem) or the "POWER" switch is turned to ON mode (vehicles with a smart
key 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 automatic
mode.
