3-1. Using the air conditioning system and defogger
■Using the automatic mode
Fan speed is adjusted automatically accord ing to the temperature setting and ambi-
ent conditions. As a result, the following may occur:
●The system may switch automatically to recirculated air mode when the coolest
temperature setting is selected when the ambient temperature is high.
●Immediately after is pressed, the fan may stop for a while until warm or
cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to in
accordance with the temperature setting and the inside temperature.
■Using the system in outside air mode
As hot air from the hood grilles may flow through the air outlets, it is recommended
that the air conditioning system be turned on while outside air mode is used.
■Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
■When is selected for the air outlets used
For your driving comfort, air flowing to th e feet may be warmer than air flowing to

■When the outside air temperature approaches 32 F (0C)
The air conditioning system may not operate even when “A/C” is selected on the
operation screen.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. 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.
