Separate left and right temperature controls allow the driver and front passenger to enjoy personalized comfort, while a third zone is dedicated to the rear cabin. In addition to fully automatic or manual control of blower speed and airflow distribution, the system includes a humidity sensor, a dust/pollen filter, and an activated charcoal filter that helps remove odors from the cabin air. The rear-cabin settings can be adjusted from control panels both in the dash and in the second row.
