porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
● Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.

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.
