Lexus engineers spent two years in the Middle East and Arctic Circle developing an advanced air conditioning system that can cope with harsh temperature extremes. Two powerful air conditioning units and twenty-eight air vents throughout the cabin distribute air at just the right temperature quietly and evenly throughout the cabin, without unwelcome drafts. The air conditioner also features Multi-zone Automatic Climate Control that enables occupants in the front seats and outboard second and third row seats to set their individual climate zone preferences. For colder weather the front seats have heaters.
