■ Registering air conditioning settings to electronic keys
● Unlocking the vehicle using an electronic key and turning the power switch to ON
mode will recall that key’s registered air conditioning settings.
● When the power 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 passenger

Settings for the electronic key and the corresponding door can be changed. Contact
