Active Ventilated seats are a luxury you'll soon consider a necessity. Three levels of heating and cooling ventilation are offered. By gently circulating air through perforations in the seat and backrest, Active Ventilated seats help keep you cooler and your clothes drier during warmer months. New reversible fans can draw heat away for brief periods. On cold or damp days, using both the ventilation and heating together can circulate the seat heating more quickly, to help keep you warm and dry.
