When the outside temperature exceeds 75 F (24 C) and the air condition-
ing system is on

ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the en gine switch
is turned to the “ON” position (vehicles without a smart key sy stem) or IGNI-
TION ON mode (vehicles with a smart key system).

be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in aut omatic
