The powerful yet energy efficient S-Flow technology provides climate control only to the zones that are occupied. Switching on the S-Flow cuts air conditioning for the rear seats. For models with optional 3-zone independent temperature controls, air conditioning of the front passenger’s side is also cut automatically when the seat isn’t occupied, further contributing to energy efficient control. Switching to Eco Mode provides intelligent control of the air conditioning, to help reduce overall power consumption. Another climate control innovation is “nanoe” technology that releases microscopic, negatively charged “nanoe” particles in the cabin(Optional). By attaching themselves to airborne particles, these “nanoe”ions help to purify the cabin air and effectively deodorize the seats and upholstery.
